Opis:: In this short communication describing experiments carried out on the larvae of two insects, Unaspis euonymi Comstock (feeding on Euonymus japonicus Thunb.) and Dynaspidiotus britannicus Newstead (feeding on Laurus nobilis L.), we evaluate for the first time the efficiency of using DNA insecticides in the control of sap-sucking insects, including armored scale insects. Over a period of 10 days, high insect mortality was detected in both U. euonymi and D. britannicus, accompanied by a significant decrease in the concentration of target RNAs. At the same time, no visible changes were observed when the leaves of the host plants were subjected to treatment with DNA insecticides for one month. The results show the high efficiency of DNA insecticides used against hemipteran insect pests. It is noteworthy that the high efficiency of DNA insecticides and their low cost in comparison with RNA preparations provides a safe and extremely promising potential vehicle for the control of sap-sucking insects.

Opis:: Azadirachtin is the most active substance separated from Azadirachta indica. lt acts destructively on numerous species of insects and mites. The aim of the presented investigations was to determine the effect of azadirachtin on one of the most dangerous pests of cabbage plants, Pieris brassicae, and on its natural enemy, Apanteles glomeratus. The results of the field observations did not show any repellent effect of azadirachtin relating to laying their eggs cabbage butterflies. However, a significant effect of the azadirachtin solution on reduction the number of cabbage butterfly caterpillars (it was more distinctly marked in respect to young larva stages) as well as on limited feeding by caterpillars. No negative influence of azadirachtin on a parasite of Pieris brassicae caterpillars, Apanteles glomeratus was distinctly shown.
Azadirachtyna jest najbardziej aktywną substancją wyizolowaną z Azadirachta indica. Działa szkodliwie na liczne gatunki owadów i roztoczy. Celem przedstawionych doświadczeń było określenie jej wpływu na jednego z najgroźniejszych szkodników roślin kapustnych bielinka kapustnika (Pieris brassicae) oraz na jego wroga naturalnego baryłkarza bieliniaka (Apanteles glomeratus). Wyniki przeprowadzonych obserwacji polowych nie wykazały repelentnego działania azadirachtyny w stosunku do składających jaja motyli bielinka. Stwierdzono natomiast znaczący wpływ preparatu na redukcję liczby gąsienic bielinka kapustnika (wyraźniej zaznacza się to w odniesieniu do młodszych stadiów larwalnych) oraz na hamowanie pobierania pokarmu przez gąsienice. Nie wykazano wyraźnie negatywnego wpływu azadirachtyny na pasożyta gąsienic bielinka – baryłkarza bieliniaka.

Opis:: Obiekt prezentowanych badań stanowiła populacja kapturnika zbożowca (Rhyzopertha dominica F.), groźnego szkodnika magazynowanego ziarna zbóż i produktów spożywczych. Czynne przemieszczanie się osobników dorosłych tego gatunku po gładkiej powierzchni nie jest możliwe z powodu budowy ich ciała, jednak bardzo sprawnie poruszają się w obrębie pryzm ziarna. Wykazują, podobnie jak populacje innych chrząszczy spichrzowych, dużą aktywność migracyjną. Celem badań laboratoryjnych było zbadanie przebiegu procesu migracji w początkowym okresie zasiedlania ziarna pszenicy przez tego szkodnika. Ocenę aktywności migracyjnej oparto na analizie liczebności populacji oraz wskaźników: migracji, śmiertelności i struktury płciowej. Jako substrat w eksperymentach zastosowano pszenicę - optymalny pokarm dla tego gatunku owada. Badania prowadzono w temperaturze 28°C i RH 60 ±5 %. Stwierdzono, że rozprzestrzenianie się populacji kapturnika zbożowca w warunkach swobodnych migracji dwukierunkowych w początkowym okresie zasiedlania pokarmu prowadzi do szybkiego, równomiernego opanowywania całego dostępnego substratu. Ponadto samice tego gatunku wykazują wyższą aktywność migracyjną. Prowadzi to do rozprzestrzeniania się populacji i atakowania coraz to nowego ziarna zbóż. Stwierdzonej aktywności migracyjnej towarzyszy bardzo niska śmiertelność populacji.
The subject of presented study were populations of the lesser grain borer (R. dominica), a dangerous pest for stored cereal grain and food products. The active relocation of adult individuals of this species on smooth surfaces is impossible because of their body structure; however, they move very agilely on the areas of grain heaps. They demonstrate a high migration activity, similar to that observed in populations of other granary beetles. In laboratory tests the migration process in initial period of grain colonization by the pests was examined. The assessment of migration activity was based on analysis of population numbers and focused on determinants concerning migration, mortality rate and gender structure. Wheat was used in experiments, as the parent substance - optimal fodder for this insect species. The experiments were conducted at 28°C and 60 ±5 % r.h. It was found out that propagation of the lesser grain borer populations under undisturbed bi-directional migration conditions, during initial period of food colonization, leads to quick and uniform seizure of all substrate available. Moreover, females of this species demonstrate a higher migration activity. This results in propagation of the population and leads to attacks on other, new cored grains. Discovered migration activity was accompanied by very low mortality ratio.

Opis:: This study investigated insect pest infestation of maize, millet, sorghum, rice and wheat grains traded in the three main markets namely Monday, Baga-Road and Custom-Park markets in Maiduguri, Borno state, Nigeria. Sampling lasted from January to June 2012. Samples per grain type, each weighing one kilogram, were obtained every two weeks from ten randomly selected traders per market. Each sample was sieved in the laboratory to recover all adult insects present, both at sampling and also after one month stay (laid out in a completely randomized design). In each market, Sitophilus zeamais Motschulsky and Rhyzopertha dominica (F.) followed by Tribolium castaneum Herbst, Sitophilus oryzae (Linnaeus), Trogoderma granarium (Everts) or Cryptolestes sp. were the insect pests commonly found attacking more (between two to five) grain types. Observed highest and lowest mean insect numbers were respectively by S. zeamais in maize grains (12.13 individuals in Monday market) and T. granarium in wheat grains (0.13 individuals in Baga-Road market). Results unveil that among three markets, higher mean total numbers of insects were present in maize, rice or wheat (18-33). For all grain types, the mean numbers of damaged grains were significantly higher in Monday (53-357) and Custom-Park (46-302) than in Baga-Road (17-109) markets. Furthermore, the mean total number of damaged grains across markets was significantly higher maize, followed by rice and wheat (55-231) than in other grain types (37-41). The implications of all these results on insect infestation of different cereal grain types sold in these markets are discussed.

Opis:: The effects of powdered herbs (lavender Lavandula officinalis L., peppermint Mentha piperita L. and basil Ocimium basilicum L.) added to the food substances of three insect species: the rice weevil Sitophilus oryzae (L.), lesser grain borer Rhyzopertha dominica (F.), and the saw-toothed grain beetle Oryzaephilus surinamensis (L.) on the life span and development of the three insect species as well as habitat conditions, sex structure, and the survivability of males and females were considered. The experiments were conducted in the laboratory at a temperature of 28°C and relative humidity (RH) 60 ±5%. In all the studied populations, high female mortality was found (♂/♀ < 1). The studied populations were: the rice weevil and the lesser grain borer cultured in wheat grain with herb additions, and the saw-toothed grain beetle cultured in semolina with herb additions. Among the herbs used, peppermint caused a significant effect in the form of increased mortality rates among females of S. oryzae and O. surinamensis. Lavender and basil had a similar impact among R. dominica females. The herbs applied in the experiments intensified the mortality of females and, consequently, led to the disappearance of entire populations.

Opis:: Określono wrażliwość prusaków (Blattella germanica L.) różnorodnych pod względem wieku i płci, na owadobójczy biopreparat z Bacillus thuringiensis var. kurs taki (Dipel).
In the studies conducted for finding of biological factors effectively controlling insects of hygienic importance German cockroaches were subjected to the action of an insecticide containing spores of Bacillus thuringiensis var. kurstaki. One gram of the insecticide contained 25 miliard (US billion) spores with protein endotoxin crystals. The inscets were given drinking water and food containing 1.0%, 0.5%, 0.25%, 0.125% of the initial preparation. The experiment was carried out on 1800 cockroaches. Half of them (600 mature insects differentiated for sex and age and 300 larvae in stage 1st of development) were treated with the preparation, the remaining insects served for control. The insects were kept at about 28°C. After 9 days o the experiment in the group receiving 1% Dipel on food 76.4% mature insects and 83,0% larvae in 1st stage of development died. After 14 days all males died, and after 17 days died all females. In the control group died in that time 2.3% and 3.4% respectively. In case of lower per cent of the preparation in food the time of dying was prolonged, and at the lowest per cent it was 22 days. The study showed that Dipel effectively reduced the population of German cockroaches, and although in initial period its action was slower than that of chemical agents, it could be used for the control of these insects, especially as it in non-toxic for humans, warm-blooded animals and useful insects.

Opis:: Th e present exploration is focused on the bio-fabrication of silver nanoparticles (Ag NPs) using Trichodesma indicum aqueous leaf extract as a reducing agent. Th e synthesized Ag NPs were productively characterized by UV-vis spectroscopy, XRD, and TEM studies. Th e photosynthesis of Ag NPs was done at room temperature for 24 h and at 60°C. Th e green synthesis of spherical-shaped Ag NPs bio-fabricated from T. indicum with a face centred cubic structure showed average particle sizes of 20–50 nm, which is inconsistent with the particle size calculated by the XRD Scherer equation and TEM analysis. We further explored the larvicidal effi cacy of biosynthesized Ag NPs with leaf extracts of T. indicum against Mythimna separata. Th e results showed that Ag NPs (20–50 nm) of T. indicum possess good larvicidal activity against M. separata with an LC50 of 500 ppm. Th us, we can advocate that Ag NPs of 20–50 nm size extracted from T. indicum may be considered in the pest management programme of M. separata in future.

Opis:: Efforts have been made during the past three decades to develop insecticides with selective properties that act specifically on biochemical sites present in a particular insect group, but whose properties differ from those present in mammals. This approach has led to the discovery of compounds that affect the hormonal regulation of molting and developmental processes in insects such as ecdysone agonists, juvenile hormone (JH) mimics and chitin synthesis inhibitors. The search for potent acylureas has led to the development of novaluron (Rimon) developed by Makhteshim Chemical Works. The LC-50 value of novaluron on 3rd-instar Spodoptera littoralis fed on treated leaves is approximately 0.1 mg a.i./liter. This value resembles that of chlorfluazuron and is tenfold lower than that of teflubenzuron. Novaluron affects nymphs of Bemisia tabaci more than chlorfluazuron and teflubenzuron. Artificial rain, at a rate of 40 mm/h applied 5 and 24 h after treatment in a cotton field had no appreciable effect on the potency of novaluron on both S. littoralis larvae and B. tabaci nymphs. Hence, novaluron can be used in tropical areas and during rainy seasons. In general, benzoylphenyl ureas had no direct effect on parasitoids and phytoseiids and are considered mildly affect other natural enemies. Novaluron has no cross-resistance with conventional insecticides, the JH mimics pyriproxyfen and neonicotinoids. As such, it is considered an important compound in pest management programs.

Plots were arranged in a Randomized Complete Block Design (RCBD), with three replications. Three insect pests of okra (Podagrica uniformis, Podagrica sjostedti and Zenocerous variegatus) were observed on the field. Cypermethrin applied singly and Cypermethrin combined with plant extracts effectively controlled observed insect pests, followed by lone application of plant extracts (L camara, T. vogelii and Z. officinales plant extracts at 1st and 2nd season. Okra yield revealed that both plant extract and Cypermethrin combined with plant extract were not significantly different from one another at first season and at second season Cypermethrin combined with plant extracts performed better than Cypermethrin applied singly. This study indicates that the studied plant extracts can be good synergist for Cypermethrin in controlling field pest of okra.

Opis:: Beauveria bassiana is an entomopathogenic fungus that is widely used in Thailand to control pest insects. However, the increasing temperature has influenced the insect control efficiency of the fungus. Therefore, determination of thermotolerant isolates of B. bassiana that can grow and remain pathogenic at higher temperatures than its current optimum temperature may be a better way to control pest insects in a high temperature environment. Three isolates of B. bassiana obtained from the Rice Department, Thailand were selected for mutagenesis using ethyl methanesulfonate (EMS) with subsequent screening at high temperatures (33 and 35°C). In addition, the recovery of fungal growth after exposure to a high temperature for a period of time (5–15 days) and then transferring to 25°C was evaluated. No isolates were found that grew at 35°C but one mutant isolate (BCNT002MT) produced larger diameter colonies and more spores than the corresponding wild type (WT) at 33°C. Growth and spore production of the BCNT002MT isolate were greater than its WT when incubated at 25°C for 14 days following exposure to 33°C for 7 days. In addition, the spore germination level (%) of BCNT002MT was significantly higher than its WT during culture at 25°C after prior exposure to 33°C for 5, 10 and 15 days. The pathogenicity against the brown planthopper, Nilaparvata lugens (Stål), of this mutant isolate was also prominent.

Based on significant similarity of the shape and size of apple and tomato fruits the relation between the doses of active ingredients of plant protection products and their residue levels immediately after treatment was derived for the apples and then quality indices and the risks for human health were estimated. It was found that many of the currently in force MRLs need to be revised and the exposure of consumer should not exceed the acceptable daily intakes (ADIs) and acute reference doses (ARfDs) for pesticide residues.

The subject of the study were comparison of control and infested by Acyrthosiphon pisum (Harris) vegetative parts of pea plants. In the pea plants six flavonol aglycones were identified: quercetin, kaempferol+RCO-, kaempferol, tricin, apigenin+RCO-, and apigenin. In infested plants relatively high concentration of total phenols, o-dihydroxyphenols and total flavonoids in comparison with control were observed. It suggests that phenolics have negative effect on insects and they are good for control of the insect pests.

Opis:: Global warming and climate change are some of the most widely discussed topics in today's society, and they are of considerable importance to agriculture globally. Climate change directly affects agricultural production. On the other hand, the agricultural sector is inherently sensitive to climate conditions, and this has made the agricultural sector one of the most vulnerable sectors to the effects of global climate change. Rising CO2 levels in the atmosphere, increased temperature, and altering precipitation patterns all substantially influence agricultural insect pests and agricultural productivity. Climate change has a number of implications for insect pests. They can lead to a decreased biological control effectiveness, particularly natural enemies, increased incidence of insect-transmitted plant diseases, increased risk of migratory pest invasion, altered interspecific interaction, altered synchrony between plants and pests, increase in the number of generations, increased overwintering survival, and increase in geographic distribution. As a consequence, agricultural economic losses are a real possibility, as is a threat to human food and nutrition security. Global warming will necessitate sustainable management techniques to cope with the altering state of pests, as it is a primary driver of pest population dynamics. Future studies on the impacts of climate change on agricultural insect pests might be prioritized in several ways. Enhanced integrated pest control strategies, the use of modelling prediction tools, and climate and pest population monitoring are only a few examples.

Opis:: Leaf beetles and fruitfly infestation greatly limits water melon (Citrullus lanatus) production throughout the tropics. The efficacy of aqueous plant extracts applied at 5 % w/v concentration of two botanicals (neems seed oil and garlic bulb) and 1.5 melt of one synthetic insecticide (karate 2.5 EC) against their infestation were evaluated. The effects of these treatments including control on the number of the insects, number of leaves, vines, length of vines, number of fruits, fruit weight, fruit damaged and undamaged were assessed during 2012 and 2013 cropping seasons in Lawanti, Gombe state, Northern Guinea Savannah region of Nigeria. Result of the study showed that neem seed oil and garlic bulb treatments at 5 % w/v were effective against the leaf beetles and water melon fruitfly as the synthetic insecticide karate 2.5 EC in managing the water melon insect pests. Karate 2.5 EC significantly reduced the infestation of the insect pests of water melon and increased number of leaves, vines, length of vines, number of fruits, fruit weight and number of undamaged fruits/plot followed closely by neem seed oil (A. indica) and garlic bulb (A. sativum) extracts. Water melon a growth and fruit yields were appreciably improved in these treatment while untreated control water melon crops had more leafs beetles and fruitfly infestations, poor plant growth and lower fruit yields. Both botanicals can thus serve as alternatives to synthetic insecticides for managing water melon leaf beetles and fruitfly attack.

Opis:: Three date cultivars were sourced from the open market, sterilized and infested with Oryzaephilus surinamensis L. in a no-choice infestation experiment to determine emergence and weight loss. Emergence of O. surinamensis in Jigawa cultivar with and without calyx was significantly higher (P≤0.05) than emergence in Mali and Deglet Noor with and without calyx, just as emergence in Mali cultivar without calyx was significantly (P≤0.05) higher than emergence in Deglet Noor with and without calyx. Based on cultivar, Deglet Noor gave the least emergence of O. surinamensis, with the highest in Jigawa cultivar. There was a highly significant (P≤0.05) weight loss in Jigawa date cultivar compared with weight loss in both Deglet Noor and Mali date cultivars. Moreover, dates without calyx had significantly higher (P≤0.05) weight loss compared with dates with calyx. Finally, pulpy dates appeared to be the most susceptible cultivars, whereas firm dates were the least susceptible date cultivars. Conclusively, the results showed that Deglet Noor cultivar with calyx had the least emergence of O. surinamensis, as well as loss in weight, and is, therefore, recommended to store-owners for prolonged storage.
