Opis:: Pine processionary, Thaumetopoea pityocampa Denis and Schiffermüller, 1775 is a moth that belongs to the order of insects Lepidoptera, and family Notodontidae. The larvae of pine processionary moth are the main pest of pines all over the world, but mainly in Mediterranean region. The contact with pine processionary caterpillar (lepidopterism) can produce a strong inflammatory reaction on skin and mucous membranes. Other findings include hyperthermia, tachypnoea, respiratory distress, cyanosis and tongue oedema, labial angioedema, ptyalism, bilateral submandibular lymphadenomegaly, conjunctivitis and severe tongue necrosis. Tough, few veterinary cases have been published. Also in Poland pine processionary moth (Thaumetopoea pinivora) is present, especially near the Baltic coast and can be a possible health risk for both humans and animals (especially dogs). The aim of this article is to increase knowledge about the clinical manifestations of pine processionary caterpillar contact, which may be useful for diagnosis of this dangerous disease.

Opis:: The mechanisms underlying larval diapause in the wax moth (Galleria mellonella) is one of the most throughly studied aspects. At the low temperature of 18°C, the last instar larvae did not pupate but transferred to 30°C they initiated development and pupation in a circadian manner. Different types of surgical manipulations including head-ligation, nerve cord-severance, implantation of the brain, prothoracic glands, accompanied with ecdysteroid titre measurements indicated that diapausing arrest of larval development at 18°C might be due to the nervous inhibition of their prothoracic glands.

Opis:: Fault diagnosis is part of the maintenance system, which can reduce maintenance costs, increase productivity, and ensure the reliability of the machine system. In the fault diagnosis system, the analysis and extraction of fault signal characteristics are very important, which directly affects the accuracy of fault diagnosis. In the paper, a fast bearing fault diagnosis method based on the ensemble empirical mode decomposition (EEMD), the moth-flame optimization algorithm based on Lévy flight (LMFO) and the naive Bayes (NB) is proposed, which combines traditional pattern recognition methods meta-heuristic search can overcome the difficulty of selecting classifier parameters while solving small sample classification under reasonable time cost. The article uses a typical rolling bearing system to test the actual performance of the method. Meanwhile, in comparison with the known algorithms and methods was also displayed in detail. The results manifest the efficiency and accuracy of signal sparse representation and fault type classification has been enhanced.

The epizootic induced by the fungus B. bassiana in 1994 caused about 92% reduction of the pest population. That has been noted for the first time in a natural population of S. salicis in Poland.
Badania nad entomopatogennymi grzybami prowadzono w latach 1972 - 1996 na 33 populacjach białki wierzbówki Stilpnotia salicis L. pochodzących z 12 województw: bydgoskiego, ciechanowskiego, kaliskiego, katowickiego koszalińskiego, leszczyńskiego, legnickiego, płockiego, poznańskiego, toruńskiego, włocławskiego i zielonogórskiego. Trzynaście badanych populacji zakażonych było grzybami, w tym w jedenastu stwierdzono mieszaną infekcję z wirusami. Wyizolowano 6 gatunków grzybów: Aspergillus flavus Link ex Fr., Beauveria bassiana (Bals.) Vuill., Acremonium sensu Gams, Fusarium sp. Link ex Fr., Paecilomyces farinosus (Holm. ex Gray) Brown et Smith oraz Paecilomyces fumosoroseus (Wize) Brown et Smith. Obserwowana w 1994 roku epizoocja wywołana przez grzyb B. bassiana spowodowała około 92% redukcję populacji szkodnika. Zjawisko to notowane było po raz pierwszy w naturalnej populacji S. salicis w Polsce.

Opis:: The high efficiency of baculovirus infection is partially explained by the ability of the virus to suppress host defense machinery connected with the apoptosis pathway. Members of the baculovirus gene family, inhibitors of apoptosis (vIAPs), have been shown to inhibit apoptosis in baculovirus-infected cells. Here we showed that treatment of the LdMNPV- -infected 1st instar gypsy moth (Lymantria dispar) caterpillars with sense (oligoBIR) and antisense (oligoRING) DNA oligonucleotides from the LdMNPV IAP3 gene induced elevated mortality of the insects. Apoptotic DNA ladder assay showed that the leading role in this phenomenon is played by the antisense oligoRING fragment of the vIAP3 gene. These results imply that the application of both antisense DNA oligonucleotides from vIAP genes and baculovirus preparations (one following the other) may be a potential method for plant protection against insect pests.

Opis:: The Mediterranean flour moth, Ephestia kuehniella Zeller, is a major pest of stored grain products, particularly flour. There have been major concerns over the application of conventional insecticides in stored products, which have strongly demonstrated the need for applying such alternative safe compounds as essential oils. The aim of the present study is to investigate the chemical composition and fumigant toxicity of essential oil from Ziziphora clinopodioides Lam. against the eggs, larvae, and adults of E. kuehniella. All toxicity tests were carried out under laboratory conditions set at 26±1°C and 70% relative humidity (RH). The results of gas chromatography- -mass spectrometry (GC/MS) analysis indicated that the essential oil extracted from the leaves of Z. clinopodioides, is rich in pulegone (49.4%), piperitenone (10.7%), menthone (8.9%), and 1,8-cineol (6.9%). Based on the bioassay results, the LC50 value of the tested oil was estimated to be 54.61 μl · l–1 air for larvae and 1.39 μl · l–1 air for adults. Also, it is shown that increasing the oil concentration resulted in a significant increase in oviposition deterrency as well as a considerable reduction in the egg hatching percentage. These results suggest that Z. clinopodioides oil could be a potential candidate as a fumigant for managing E. kuehniella in stored products.

Opis:: 5.8S ribosomal RNA plays an important role in protein synthesis and eukaryotic ribosome translocation. Contact DNA insecticides based on antisense fragments of 5.8S ribosomal RNA gene of gypsy moth Lymantria dispar L. showed prospective insecticidal activity on its larvae. The most pronounced insecticidal effect was found for antisense fragments 10 and 11 nucleotides long (oligoRIBO-10 and oligoRIBO-11), whereas 12 nucleotides long fragment (oligoRIBO-12) caused the lowest level of insect mortality. This data corresponds to results obtained earlier using rabbit reticulocyte and wheat germ extracts, where maximum inhibition of protein synthesis was observed when a relevant oligomer 10-11 nucleotides long was used, whilst longer chain lengths resulted in reduced inhibition. Using oligoRIBO-11 fragment we have shown penetration of antisense oligonucleotides to insect cells through insects’ exoskeletons. MALDI technique registered the penetration of the oligoRIBO-11 fragment into insect cells after 30 min and a significant response of insect cells to the applied oligonucleotide after 60 min, which indicates not only that the oligonucleotide enters the insect cells, but also the synthesis of new substances in response to the applied DNA fragment. Contact DNA insecticides developed from the L. dispar 5.8S ribosomal RNA gene provide a novel biotechnology for plant protection using unmodified antisense oligonucleotides.

Opis:: The codling moth (CM), Cydia pomonella (L.), causes heavy damage in Bulgarian apple orchards. Conventionally treated orchards, were monitored in this study. In spite of numerous chemical treatments, these orchards showed increasing flight densities of CM moths, growing populations of hibernating larvae and rising fruit damage rates. Thus, the control of CM by conventional spraying programmes became ineffective, apparently due to the development of resistance to insecticides. Products based on the Cydia pomonella granulosis virus (CpGV), such as Madex®, may provide alternative control tools that can be applied with other approaches, for a sustainable control strategy. The trials were carried out in Central-South and South-East Bulgaria, in 2006-2010. Four treatments of Madex® against the first generation, and six treatments against the second generation kept the fruit damage and population density of CM at a low level. Based on the obtained results, different control strategies have been suggested, depending on the initial CM pressure in a particular orchard. Madex® may be a promising alternative to traditional programmes of CM control. Its dose, however, should be adjusted to the initial CM population density. Also, at a high or moderate CM population density Madex® applications should be combined with MD to avoid resistance of CM to granulovirus. At the peak of CM hatching, additional chemical treatments may be sometimes necessary. Such treatments include using insecticides which are still effective against CM.

Opis:: Control failure of pests and selectivity of insecticides to beneficial arthropods are key data for the implementation of Integrated Pest Management (IPM) programs. Therefore, the aim of this study was to assess the control failure likelihood of Plutella xylostella and the physiological selectivity active ingredients to parasitoid Oomyzus sokolowskii (Hymenoptera: Eulophidae) and to predators Polybia scutellaris (Hymenoptera: Vespidae) and Lasiochilus sp. (Hemiptera: Anthocoridae). In bioassays, P. xylostella larvae and O. sokolowskii, P. scutellaris and Lasiochilus sp. adults were used. Concentration-mortality curves of six insecticides for P. xylostella were established. These curves were used to estimate the mortality of P. xylostella at the recommended concentration, in order to check a control failure of insecticides to this pest. Furthermore, the lethal concentration for 90% of populations (LC90) and the half of LC90 were used in bioassays with the natural enemies to determine the selectivity of these insects to insecticides. All tested insecticides showed control failure to P. xylostella, indicated by high LC90 and low estimated mortalities (less than 80%). The cartap insecticide was selective in half of LC90 to Lasiochilus sp. and moderately selective in LC90 and the half of LC90, to Lasiochilus sp. and P. scutellaris, respectively. Deltamethrin was moderately selective in the half of LC90 to predator Lasiochilus sp. Cartap, carbaryl, and deltamethrin reduced the mortality of Lasiochilus sp. in the half LC90. The results also showed that the insecticides methamidophos, carbaryl, parathion methyl and permethrin were not selective to any of the tested natural enemies. The role of insecticides in IPM systems of Brassica crops is discussed based on their control failures to P. xylostella and selectivity to their natural enemies.

Opis:: The physiological response of Phalaenopsis × hybridum ‘Innocence’ to biotic stress caused by Pseudococcus longispinus feeding was investigated. The condition of the cytoplasmic membranes expressed by a value of electrolyte outflow (EL) and TBARS and the activity of antioxidative system enzymes: catalase and peroxidase, and the amount of non-enzymatic antioxidant – proline, were determined. The changes in all the analyzed physiological parameters depended on the duration of the pest feeding. The outflow of electrolytes, TBARS content and catalase activity was the highest in the first period of the experiment (after 24-hour of mealybug feeding). Significant increase of peroxidase activity and proline content was noted after 7 days of insects feeding. The values of all analyzed parameters (except EL) demonstrated a decreasing tendency after 14 days of P. longispinus feeding. The observed reaction of P. hybridum ‘Innocence’ testifies to mechanisms triggered with the aim of neutralizing the effects of biotic stress and enabling the normal functioning of the cells in the orchid plants colonized by longtailed mealybug.
Badano fizjologiczną reakcję P. × hybridum ‘Innocence’ na stres biotyczny wywołany żerowaniem P. longispinus. Określono stan błon cytoplazmatycznych wyrażony wartością wypływu elektrolitów (EL) i zawartością substancji reagujących z kwasem tiobarbiturowym (TBARS), a także aktywność enzymów systemu antyoksydacyjnego: katalazy i peroksydazy, oraz ilość nieenzymatycznego antyoksydanta – proliny. Zmiany w wartowniach wszystkich analizowanych parametrów zależały od długości żerowania szkodnika. Wartość EL, zawartość TBARS oraz aktywność katalazy były najwyższe w pierwszym terminie eksperymentu (24-godzinne żerowanie czerwca). W przypadku aktywności peroksydazy i zawartości proliny istotny wzrost notowano dopiero po 7 dniach Żerowania. Po 14 dniach od zasiedlenia storczyków wartości wszystkich analizowanych parametrów (wyjątek EL) wykazywały wyraźną tendencję spadkową. Obserwowana reakcja P. hybridum ‘Innocence’ świadczy o uruchomieniu przez rośliną mechanizmów, których zadaniem jest neutralizacja skutków stresu biotycznego i umożliwienie komórkom powrotu do normalnego funkcjonowania.

Opis:: Bollworms comprise the most harmful and economically relevant species of lepidopteran. Helicoverpa gelotopoeon (D.) (Lepidoptera: Noctuidae) is native to America and affects many crops. Tobacco is an industrial crop in which methods of pest control rely mainly on the application of insecticides. To develop new eco-friendly strategies against insect pests it is very important to overcome the side effects of insecticides. The utilization of fungal entomopathogens as endophytes is a new perspective that may accomplish good results. The present study aimed to evaluate the ability of endophytic Beauveria bassiana (Bals.-Criv.) Vuill. to affect H. gelotopoeon life parameters and feeding behavior on tobacco plants. Beauveria bassiana LPSC 1215 as an endophyte did not reduce the amount of vegetal material consumed by H. gelotopoeon larvae but affected the life cycle period of the plague, particularly the larval and adult stages. Also, egg fertility was affected since adults laid eggs that were not able to hatch. The results of this investigation provide new information on endophytic entomopathogen potential to be incorporated in Integrated Pest Management (IPM) programs.

Opis:: Future climatic warming may modifyinsect development, sex ratio, quantitative changes in populations that could affect the frequency of outbreaks. Here we analyzed the influence of temperature on larval growth and development in the gypsy moth (Lymantria dispar L.). The larvae were reared at three constant temperatures: 15, 20 or 25°C, and fed with leaves of the English oak (Quercus robur L.). Larval mortality, duration of development (DD), relative growth rate (RGR), total mass of food eaten (TFE), and pupal mass (PM) were estimated. Larval mortality was lowest at 20°C, higher at 25°C, and highest at 15°C. DD significantly decreased with increasing temperature and depended on sex. The influence of temperature on the shortening of DD was stronger in males than in females. RGR significantly depended on temperature and was the highest at 25°C, and lowest at 15°C. At 15°C, RGR did not change markedly with time. In contrast, RGR at 20°C was characterized bya continuous decreasing trend. At 25°C, RGR was very high for 2 weeks but quickly declined afterwards. Temperature did not affect the TFE. PM was significantly correlated with temperature and sex. PM of females was higher at 20°C than at 15 and 25°C, in contrast to that of males, which was similar at 20 and 25°C, and higher than at 15°C. For larval growth and development, the most favourable was the medium temperature (20°C). The least favourable temperature for females was 25°C, for males 15°C. The results suggest that global warming may modifythe future sex ratio of gypsy moths that may affect insect development and outbreaks.

Opis:: Potato is one of the most important food crops with a capacity to abate hunger among farmers in the region. However, its productivity has stagnated and remained low due to poor agronomic practices applied by smallholder farmers. To avert this situation, dissemination through training of already existing better technologies and practices should be prioritized. A lot of research has been done with better recommendations- use of disease-free tuber seeds from high yielding and tolerant varieties, adequate application of balanced nutrients, timely scouting and integrated management of pests and diseases and good harvesting practices are available for immediate adoption. The adoption and dissemination could be facilitated by currently existing policies that promote cross-border movement and diffusion of research technologies and new varieties.
