Opis:
Antifeedants, or food deterrents, are substances that, by acting on the sense of taste of insects, entirely or partially inhibit their feeding and can be used to reduce the population of harmful species. Antifeedants have the advantage of low toxicity and high selectivity towards selected groups of pests, providing an alternative to the classically used insecticides, which usually have a broad spectrum of action and greater toxicity, even towards vertebrates. Among their numerous activities, lactones can exhibit antifeedant properties. However, the use of natural lactones as antifeedants is limited due to their low isolation yields from natural sources and complex chemical synthesis. Therefore accesible synthetic compounds are of great interest. This work presents the synthesis pathways and the deterrent activities of the lactones obtained in convenient transformations, often from natural terpene precursors.

Opis:
As the global human population continues to grow, the demand for food rises accordingly. Unfortunately, anthropogenic activities, climate change, and the release of gases from the utilization of synthetic fertilizers and pesticides are causing detrimental effects on sustainable food production and agroecosystems. Despite these challenges, there remain underutilized opportunities for sustainable food production. This review discusses the advantages and benefits of utilizing microbes in food production. Microbes can be used as alternative food sources to directly supply nutrients for both humans and livestock. Additionally, microbes offer higher flexibility and diversity in facilitating crop productivity and agri-food production. Microbes function as natural nitrogen fixators, mineral solubilizers, nano-mineral synthesizers, and plant growth regulator inducers, all of which promote plant growth. They are also active organisms in degrading organic materials and remediating heavy metals and pollution in soils, as well as soil-water binders. In addition, microbes that occupy the plant rhizosphere release biochemicals that have nontoxic effects on the host and the environment. These biochemicals could act as biocides in controlling agricultural pests, pathogens, and diseases. Therefore, it is important to consider the use of microbes for sustainable food production.

Opis:
Two  separate field trials, one with 22 multipurpose white-flowering cultivars  and  second with 8 cultivars of feed pea, were  conducted  to  determine the degree of  damage  to  seeds  caused  by the pea  moth (Cydia nigricana) and pea weevil  (Bruchus pisorum) and to study important agronomic traits of pea cultivars. Damage to pea seeds by the pea  moth and pea weevil was common in the central region. The pea cultivars tested differed in their susceptibility to these two pests, as reflected by the value of  percentage  seed  damage. The percentage of seed damage caused by pea weevil in  this  study was tenfold  higher than that by pea moth. Highly significant effect of years of cultivation on all examined traits was shown. Seeds  damage  by  both  insects  was most  strongly affected by  the precipitation and to lesser extent by mean  daily  temperature during pea  growing seasons.  For the set of white-flowering  cultivars, the correlation between the amount of damaged seed and the amount  of  precipitation  was r = - 0.47 and r= - 0.76 for  pea moth  and pea  weevil  respectively, while in   feed  pea cultivars only for seeds  damaged by pea weevil  a significant correlation (r= -0.84) was found. The second abiotic factor, mean daily temperature had a positive effect on the amount of damaged seeds, particularly caused  by pea weevil in feed pea (r= 0.84). The cluster analysis identified cultivars with the lowest percentage of damaged seeds and high yield performance.

A field trial is conducted to study the seasonal incidence of five pests namely Brinjal shoot & fruit borer [Leucinodes orbonalis Guenee], Hadda beetle [Henosepilachna vigintioctopunctata (Fabricius)], Mealy bug [Centrococcus insolitus (Green)], Aphid [Aphis gossypii (Glover) and White fly Bemisia tabaci (Gennadius) on brinjal in relation to weather parameters at agricultural farm of RKMVERI campus, Narendrapur during kharif & rabi crop seasons (2019-20). The brinjal crops receive pests load from 9 to 15 week plant age and 10 to 17 week plant age during kharif and rabi crop season respectively. The all five pests attain maximum peak sequentially sharing various microhabitats for feeding on host plants. Among the five pests recorded shoot & fruit borer appears as the major pest enjoying the crop to its optimum throughout the season till harvest and seems to cause heavy damage in brinjal production. Mealy bugs attack the brinjal leaves only in the kharif crop whereas white flies are encountered in the field during rabi crop season only. In kharif season during the crop growing period, borer caterpillar incidence % is significant and positively correlated with avg. temperature (°C). For rabi season due to lack of complete field data on the incidence pattern of pest species correlation coefficient values are not generated. Data generated so far prompts to assume that the pest species are now with strong genetic stability irrespective of climate change and/or improvised agronomic practices.

Opis:
Objective: Chamomile plants (Chamomilla recutita L. Rausch) are often attacked by pests, which usually cause the decrease of raw material yield and its quality. The objects of field trial were two chamomile cultivars: Złoty Łan (4n) and Promyk (2n) cultivated under organic regime. The aim of this study was to evaluate of impact of the spinosad treatment and its time of application on two chamomile cultivars: cv. Promyk – 2n and cv. Złoty Łan – 4n exposed to insect pests. Methods: The first treatment with spinosad as a preventative control (P) was performed in the early phase of plant development (seven leaves). Intervention (I) treatment was made in green bud phase. In both terms of observation insect pests were observed and collected. In each spraying application of 0.06 g of spinosad per 1 liter of water was used. Results: Spinosad was able to limit the number of pest population and finally increased yielding of the treated cultivars as compared to the untreated plants. Time of spinosad application for cv. Złoty Łan plants was not statistically siginificant, although was more effective for the preventative treatment of cv. Promyk in the increasing of the plant biomass (283.8 g · m-2) and seed (32 g · m-2) yields than intervention. Conclusion: Protection treatment with spinosad might be recommended in chamomile cultivation and it is more effective than intervention in diploid cultivar which begin blooming earlier than tetraploid. Essential oil content was not related with protection treatment for diploid cultivar, although intervention in tetraploid cultivar caused higher content of oil.

Opis:
Acantholyda posticalis Mats. for over twenty years increases the extent of occurrence and causes defoliation of Scots pine stands. The population size is estimated annually based on the autumn surveys of phytophagous insects, but accuracy of these prognoses is far from satisfactory. The aim of the study was to describe the spatial distribution of pre−imaginal stages of A. posticalis wintering in the litter and soil to improve the methods of survey currently applied in Polish forestry. The research was carried out in four forest district located in different regions of Poland. In each forest stand three following zones were outlined: the belt of trees on the edge of the stand adjoining to young plantation or thicket, the belt 15−20 m from the stand edge and the belt in the forest interior at least 30−40 m from the edge of a stand. 152 trees were examined and 1540 plots of size 1×0.5 m were established under their canopy. The pre−imaginal stages were searched within each of these plots in the litter and soil to the depth of 20 cm. Later on they were divided into eonymphae and pronymphae, and counted. The significant differences in number of pre−imaginal stages of A. posticalis between studied forest stands in different forest districts were found. The spatial distribution of larvae wintering in the litter and soil was highly variable in scale of both stand and single tree. The abundance of larvae depended on the distance from the forest edge, but the values of this parameter calculated for trees in the same zone also varied substantially. The lowest mean abundance of pre−imaginal stages of A. posticalis denoted under pines growing at the edges of trees stand. Within the canopy projection on forest floor, the distribution of larvae was significantly dependent on the distance from the tree trunk. The highest abundance was observed within one meter from the trunk. The survey method currently used for primary pine pest assessment in Polish forests bases on ten plots and five of them are located 1.5 m from the tree trunk. In the light of presented results, the assessment of A. posticalis number could be inaccurate, because half of these plots in which scrutiny of litter and soil take place, omit the areas of higher concentration of wintering stages of the pest.

Opis:
The research was carried out in the economic and natural Forest Reserve ‘Yertys Ormany’ in Pavlodarsk Oblast (Kazakhstan) in 2018. In the middle of May, two barrier traps of the ‘Netocia’ type (30, in total) were installed on each research plot damaged by wind, fire and great pine web – spinning pine sawfly – Acantholyda posticalis Mats. Insects were caught every month, from mid−June to mid−August. 1521 insects belonging to 67 species and 23 families were caught in the traps. Beetles clearly dominated. We also observed a great pine web and sirex woodwasp Sirex noctilio Fabr. Of the beetles caught, 10% were thermophilic jewel beetles or metallic wood−boring beetles Buprestidae, among which Chalcophora mariana (L.) dominated. The highest average number of individuals was observed on sites damaged by A. posticalis, however, differences between the plots turned to be insignificant. The highest significant average number of species was observed on sites damaged by the fire and by the wind. The GLM analysis indicated the highest mean values of the Margalef index in plots damaged by fire and by the wind, but did not show significant differences between the average values of the fidelity index of the assemblages. The research confirmed the hypothesis of a greater number of species and individuals, and a higher diversity of pests in pine stands more strongly disturbed (i.e. damaged by the fire and by the wind). At the same time, there were no differences between the most seriously disturbed variants.

Opis:
Bats have a set of features that make them very effective insects predators, thus they can potentially play an important role as a biological pest control agent in forests. The active flight ability, nocturnal lifestyle, high level of metabolism and a lack of a significant threat from predators make bats the most important predators of insects active in the evening and at night. All bats species noted in Poland are associated with forests, where they use various microhabitats and forage on various types of prey. According to foraging strategy and diet, insect−eating bats have been divided into several ecomorphological groups, which shows different efficacy in foraging on particular species of forest insects pests. Numerous studies indicate that bats diet includes primary forest pests from order Lepidoptera and also some species from Diptera and Coleoptera. Forest pests from Lepidoptera and Diptera represent a significant share in the diet of gleaning bats, especially long eared bats Plecotus sp., barbastelle Barbastella barbastellus and Natterer’s bats Myotis nattererii. During the swarming period Melolonthinae sp. and Amphimallon sp. (Coleoptera) dominate in the diet of all larger species of bats, especially aerial hawkers and bats foraging along the linear elements in the landscape: serotine bat Eptesicus serotinus, commone noctule Nyctalus noctula, lesser noctule Nyctalus leisleri and mouse eared bat Myotis myotis (which forage mainly on ground beetles). Moreover many bat species are able to change diet and adapt it to the most abundant prey. According to forest protection, the most important guilds are gleaners, bats foraging in the dense vegetation and canopy and aerial hawkers. Bats have a great potential as a biological control agents and all conservation practices including this group of animals will simultaneously support the natural forest resistance mechanisms.

Introduction and objective. The great number of pigeon populations in many European cities promotes the spread of the European pigeon tick (Argas reflexus), the bites of which cause local and systemic reactions. The aim was to study the occurrence of A. reflexus in several cities of Upper Silesia, and skin lesions caused by A. reflexus tick bites in humans. Materials and method. The results of investigations carried out in 1995–2002 in five cities located in the Upper Silesian conurbation are presented. Specimens of A. reflexus were collected for one hour in attics and lofts inhabited by these ticks. A history of skin lesions caused by bites was taken from residents who had been infested by A. reflexus. The development of skin lesions was monitored for three months in two individuals who had been bitten several times by these arthropods. Results. In the localities, 987 A. reflexus specimens were collected, including 334 females, 269 males, and 384 various nymphal stages. Within one hour, 38–109 ticks specimens were collected at the study sites. Cases of attacks by unengorged A. reflexus were reported in all the habitats located in the residential buildings; the ticks were also found in residents’ flats and in staircases. Residents who had been repeatedly attacked by European pigeon ticks developed a strong inflammatory reaction to the components of tick saliva, and had purple papules with necrosis in the centre of the lesion. The tick bite areas exhibited scars and hyperpigmentation. Conclusions. Individuals attacked by A. reflexus several times are at risk of development of severe persistent local reactions to bites. Pigeon ticks, trophically associated with pigeons present abundantly in the Upper Silesian conurbation and other European urban habitats, pose a serious threat to public health.

Opis:
Repeating outbreaks of the Scots pine pests, effecting in stands damages, are the most important problems of forest protection. In extreme cases they pose a real threat to the stability of stands. Naturally occurring entomopathogenic nematodes are important regulatory factors in insect populations. Many species are employed as biological agents to control the insect pests. The objectives of this research was to describe the influence of potential forest pests on occurrence and abundance of entomopathogenic nematodes. Entomopathogenic nematodes (Steinernematidae and Heterorhabditidae) were studied in woodland soils in northern Poland. Soil samples were collected from 2010 to 2015 from coniferous forests with abundant suitable insect hosts: the beetle grubs of Melolontha melolontha L. living in the soil (Coleoptera: Scarabaeidae) and foliage feeders Diprionidae spp. (Hymenoptera) and the caterpillar of Dendrolimus pini L., Panolis flammea Den. et Schiff. and Bupalus piniarius L. butterflies. Nematodes occurred in all type of forest and 171 soil samples were taken from 40 localities. Each study plot was approximately 100 m2 and 20 cm deep; 50 individual samples were taken using Egner’s stick, making the bulk sample approximately 600 cm3 in volume. The presence of entomopathogenic nematodes in the soil samples were determined using a standard Galleria mellonella baiting technique. Entomopathogenic nematodes were isolated from 52 soil samples (30,4%). Three species of the genus Steinernema (Steinernema feltiae, S. affine, S. silvaticum) and anyone of the genus Heterorhabditis were recorded. S. feltiae was the most common species and distinguished by the largest ecological flexibility especially to hosts. The largest number of S. feltiae samples was isolated in the places of butterfly outbreak P. flammea and also in the places of mass occurrence of beetle grubs of M. melolontha. In the feeding places of beetle of Scarabaeidae a high share of S. affine was noted too. The more rarely noted was S. silvaticum especially in outbreak of Diprionidae spp. The most abundance of entomopathogenic nematodes community was 140 000 ind./m2 in sites with M. melolontha grubs.

Opis:
Ślimaki nagie Deroceras reticulatum, Arion vulgaris, A. rufus, A. distinctus i A. subfuscus oraz niektóre inne gatunki z rodzin Agriolimacidae, Arionidae i Milacidae, powodują poważne szkody w uprawach roślin rolniczych, ogrodniczych i sadowniczych. Znaczne straty ekonomiczne z powodu ich żerowania występują w uprawach rzepaku ozimego, pszenicy ozimej, ziemniaka, buraka, kapusty, sałaty oraz niektórych roślin strączkowych. Najbardziej narażone na uszkodzenia są ziarniaki zbóż oraz siewki rzepaku. W celu oceny stopnia zagrożenia roślin przez ślimaki, konieczne jest prowadzenie stałego monitoringu ich występowania. Podstawą podejmowania decyzji wykonania chemicznych zabiegów zwalczania jest ustalenie liczebności ślimaków i stopnia uszkodzenia roślin oraz przekroczenie progów szkodliwości. Wzrost szkód wyrządzanych przez ślimaki wymaga doskonalenia strategii ich ograniczania, zgodnie z zasadami integrowanej ochrony roślin. Strategia ta powinna opierać się na kompleksowym wdrażaniu wszystkich znanych i potencjalnych metod, profilaktycznych, agrotechnicznych, kulturowych, biologicznych i chemicznych. Duże znaczenie, obok stosowania granulowanych moluskocydów, będzie miało wykorzystanie, alternatywnych pokarmów, mniej wrażliwych odmian oraz czynników biologicznych, w tym nicienia Phasmarhabditis hermaphrodita.
The slugs Deroceras reticulatum, Arion vulgaris, A. rufus, A. distinctus and A. subfuscus and certain other species of the Agriolimacidae, Arionidae and Milacidae families bring serious damage to agricultural, horticultural and orchard crops. Their grazing produces significant economic losses in crops of winter rape, winter wheat, potatoes, beetroot, cabbage, lettuce and certain pulses. The most susceptible to damage are grain caryopses and rape seedlings. To evaluate the degree to which plants are at risk of slug damage, the occurrence of slugs needs to be continuously monitored. Decisions on chemical treatments are based on determination of the size of slug populations and the extent of plant damage that exceeds acceptable thresholds. Increasing levels of slug damage make it necessary to improve strategies for combating these pests, in accordance with the principles of integrated plant protection. Such a strategy should be based on application of the full range of known and potential methods: preventive, agritechnical, cultural, biological and chemical. Besides the application of granular molluscicides, most important techniques shall include the use of alternative foods, less susceptible plant cultivars and biological agents such as nematode Phasmarhabditis hermaphrodita.

Essential oils as alternative synthetic pesticides for pest management of foodstuffs have recently received increased attention. Controlled and slow release formulations of essential oils are used to enhance their efficiency. Two volatile essential oils of Mentha piperita L. and Salvia officinalis L. were investigated for release rate and mortality percentage by fumigant toxicity against 1st instar larvae of Plodia interpunctella. Electrospinning was used to incorporate various concentrations of essential oils in nanofibers. Th e essential oils can be released from the nanofibers for long periods of time, from several days to several weeks. Poly(lactic acid) was used as a green polymer carrier and the essential oils were incorporated into the nanofi bers (8–15v/v% PLA). Insecticidal bioassay revealed that oil-loaded nanofibers (NFOs) were more toxic than pure essential oils (PEOs) against tested larvae. Th e LC50 and LT50 of NFOs were 1.2 and 4 times, respectively, more than PEOs. Our results indicated that PEOs completely lost their insecticidal activity after 14 days, whereas at the same period, NFOs had an average of 93% mortality when applied against P. interpunctella. Therefore, it can be concluded that nanofibers improved the persistence of the oil. This study presents S. officinalis has more toxicity and M. piperita had more persistence for controlling the larvae of indian meal moth.

Tyrophagus putrescentiae
Opis:
Mite infestation of stored products is a serious threat to food safety and public health. These stored product mites are not only serious pests of stored food but also cause allergies in humans. Thirty serum samples from patients living in suburban areas of Upper Silesia (South Poland) were tested for sensitization to two species of storage mites: Lepidoglyphus destructor [LD] and Tyrophagus putrescentiae [TP]. Patient antibodies against particular antigens were identified using anti-human anti-IgE monoclonal antibodies. Fifteen protein fractions from LD gave positive reactions with IgE antibodies and 18 from TP. Seven of the 30 samples showed positive reactions to a protein fraction measuring about 29 kDa from LD and six reacted with a fraction measuring about 25 kDa from TP. These findings may imply the existence of many protein fractions with allergenic properties besides the characterized allergens in the two tested species.

Opis:
Since its initial discovery in 1945, pitch canker caused by Gibberella circinata (anamorph Fusarium circinatum) has become one of the most important pine diseases in the world. It infests 57 pine species (including Pinus sylvestris) and Douglas−fir. F. circinatum has been reported in both nurseries and forests on all continents except Australia and Oceania. Both vegetative and reproductive parts of the host plant (i.e. stem, branches, roots, flowers, cones and seeds) can be infected by F. circinatum. For mature trees, the main symptoms include bleeding resinous cankers on the stem and branches as well as tree death. In nurseries, F. circinatum causes pre− and post−emergence damping off as well as mortality of older seedlings. Dispersal of fungal spores occurs through air, water splash, soil, insect vectors and translocation of the infected plant material. Currently there are no effective means of controlling pitch canker, although there is ongoing research into using chemical, physical and biological methods, quarantine and breeding for resistance to control this disease. The occurrence of the disease depends mainly on the presence and density of the host species, favorable climatic conditions (especially high humidity), presence of suitable vectoring and wounding agents and various stress factors. Taking into account the above−mentioned factors, threat to Scots pine in Poland should be considered marginal, but it cannot be ruled out completely. KEY WORDS

Opis:
Coroczne monitorowanie szkodliwości agrofagów jest ważnym elementem integrowanej ochrony roślin, ponieważ jest źródłem wiedzy o aktualnej zdrowotności roślin uprawnych w Polsce. Umożliwia śledzenie zmian w nasileniu szkodliwości, rejonizacji i zasięgu występowania agrofagów roślin uprawnych, określenie ich znaczenia gospodarczego, jest pomocne w prognozowaniu długoterminowym. Wszystkie obserwacje, dotyczące ogólnokrajowego monitorowania oceny szkodliwości agrofagów roślin uprawnych, aktualnie wykonywane są przez pracowników Państwowej Inspekcji Ochrony Roślin i Nasiennictwa (PIORiN) i przekazywane późną jesienią w formie raportów do Zakładu Metod Prognozowania Agrofagów i Ekonomiki Ochrony Roślin Instytutu Ochrony Roślin – Państwowego Instytutu Badawczego (IOR – PIB) w Poznaniu, gdzie tworzona jest jedyna w kraju baza danych AGRO GIS, na podstawie której corocznie opracowywany jest stan tosanitarny roślin uprawnych w kraju.
Every year monitoring of agrophages harmfulness is an important element of integrated control and gives information about phytosanitary state of agricultural plants in Poland. Such information are the base of the evaluation the tendency of pests and diseases spread as well as their economic value and helpful in long-term prognosis. Pest/diseases monitoring is provided by Plant Protection and Seed Health Inspection Service, results, as a reports, from monitoring are sent in late autumn to the Plant Protection Institute – national research institute (PPI – NRI) at the Department of Pests Methods Forecasting and Economy of Plant Control. At the Department the only base AGRO GIS in the country is created and then the every year phytosanitary state of agricultural plants in Poland is developed.
