... The impact of insect artificial diet on the egg production of females was examined for L29 consequently generations of laboratory populations Perillus bioculatus (F.) (Hemiptera: Pentatomidae, Asopinae). Particular attention is paid to the overwintered generation, which plays a key role in the rehabilitation of the predator populations after hibernation. It was shown that with an increase in the n ...
... Stage specific mortality and sex ratio adjustment in Zygogramma bicolorata Pallister (Coleoptera: chrysomelidae), were evaluated monthly for two consecutive years, 2010 and 2011, in field conditions on Parthenium hysterophorus L. Development of immature stages was considerably affected during the cold seasons of 2010 and 2011, and it was completely arrested in January. Similarly, the mortality sur ...
... In Moldova is investigated invasive entomofauna with the economic and ecological impact. Until now settled 118 species of the Hemimetabola group, belonging of 2 subclasses, 2 superorder and 7 orders. These 118 species were corellation with the database of Fauna Europaea and recorded are 24 species (20.3%), but for 94 (79.6%) mentioned with the "absent" and "no data". In the meantime there were rec ...

Abstract:
... Methyl salicylate is an organic compound produced by potato and other plants in response to insect herbivory. In other studies the compound has been shown to be attractive to numerous predatory arthropods. Experiments were conducted in Virginia to evaluate methyl salicylate lures for attracting natural enemies in potato plots to manage populations of Leptinotarsa decemlineata (Say). Abundance of p ...
... The paper reviews the diversity of seasonal cycles known in stink bugs (Heteroptera, Pentatomidae) from the temperate zone and is based on the data of 43 pentatomid species studied in detail up to date (Saulich and Musolin, 2011). All the seasonal cycles realized by pentatomids in the temperate zone can be divided into two large groups: univoltine and multivoltine cycles. In univoltine cycles, onl ...
... Marking biological control agents facilitates studies of dispersal and predation. This study examines the effect of a biological solvent, dimethyl sulfoxide (DMSO), on retention of immunoglobulin G (IgG) protein solutions applied to Diorhabda carinulata (Desbrochers) (Coleoptera: Chrysomelidae), an important biological control agent of saltcedar, either internally by feeding them protein‐labeled f ...

Abstract:
... The explosive spread of the common ragweed induced by disturbance of the natural habitats in the postwar years created an ideal vacant niche for acclimation of North American phytophagous insects introduced to the South of Russia in the 1960–70s. The propagation of these species resulted in restoration of natural succession periodicity and promoted the subsequent acclimation of the predatory stink ...

Abstract:
... The biology and bioregulatory activity of a population of the North American predatory two-spotted stink bug Perillus bioculatus F. are studied and the genetic similarity between this species of predatory bugs and other representatives of the family Pentatomidae is analyzed. It is established that P. bioculatus is of great importance for biological control of the Colorado potato beetle by the natu ...
... Froeschner (1988) records 23 species of stink bugs (Hemiptera: Heteroptera: Pentatomidae) as occurring in Washington state. Based onmaterial primarily housed in the M.T. James Entomological Collection at Washington State University, the number of species is increased to 47. Species recorded by Froeschner (1988) but not found in our collections are: Apateticus crocatus (Uhler), Chlorochroa rossiana ...
... Determining relative strengths of trophic links is critical for ranking predators for conservation biological control. Molecular gut-content analysis enables ranking by incidence of prey remains in the gut, but differential digestive rates bias such rankings toward predators with slower rates. This bias can be reduced by indexing each predator's half-life to that of the middle-most half-life in a ...
... Habitat manipulation in agroecosystems can influence predator–prey interactions. In this study, we collected foliar predators from field potato plots with different mulch treatments and assayed them for DNA of the target prey, Leptinotarsa decemlineata (Say), using species-specific primers. Concurrently, L. decemlineata larval abundance and plant damage were recorded from the same plots. Predator ...
... Cold storage of insects is a common practice used when transporting insects or to assist with efforts to increase the size of a colony. However, cold storage affects egg, nymphal and adult survival, fecundity, and egg viability. We evaluated the influence of nutrient source on the response of eggs, nymphs and adults of Perillus bioculatus when exposed to two temperatures most likely to be used for ...
... Plant cystatins, similar to other defense proteins, include hypervariable, positively selected amino acid sites presumably impacting their biological activity. Using 29 single mutants of the eighth domain of tomato (Solanum lycopersicum) multicystatin, SlCYS8, we assessed here the potential of site-directed mutagenesis at positively selected amino acid sites to generate cystatin variants with impr ...
... Fragments of two artificial diet up-regulated and two prey up-regulated transcripts were isolated from the predatory Pentatomid Perillus bioculatus using suppression subtractive hybridization. A BlastX search found similarities for two diet-upregulated clones, i.e., the tyrosine-3-monooxygenase gene and the gene for the chitin binding protein, Gasp. The probe generated from the tyrosine-3-monooxyg ...
... Recent developments in the area of nutrigenomics hold the promise of providing valuable information about the impact of nutrition on a wide range of biochemical parameters by investigating how nutrition alters global gene expression patterns. Our goal is to use a nutrigenomics approach to identify insect molecular markers that could be used as early indicators of insect responses to different nutr ...

Abstract:
... Nymphs of Perillus bioculatus F., a specialist pentatomid predator of the Colorado potato beetle, Leptinotarsa decemlineata (Say), are smaller than comparable instars of their prey. In laboratory experiments, P. bioculatus fed small prey exhibited greater capture success, increased survivorship, and faster development to adulthood than individuals fed large prey. An increase of potato beetle prey ...
... Selected morphological and physiological properties of the corpus allatum (CA)––corpus cardiacum (CC) complex from the two-spotted stinkbug, Perillus bioculatus (Hemiptera: Pentatomidae), were studied. The CAs play an important role in insect physiology because of their production of the juvenile hormones (JHs), i.e., key hormones involved in development and reproduction. We found that the P. bioc ...
... The effect of juvenile hormone (JH) III on the hemolymph composition of vitellogenin was examined in Perillus bioculatus. Adult females were treated topically with JH III, and the premature presence of vitellogenin in the hemolymph was then detected using electrophoresis and Western blot analyses. JH III treatment resulted in a dose-dependent early production of vitellogenin that was detectable 48 ...
... The impact of a zoophytogenous, insect-free artificial diet on the developmental rate, life history parameters, and fertility was examined over 11 consecutive generations for domesticated Perillus bioculatus (F.) (Heteroptera: Pentatomidae). This study showed that when fed an insect-free artificial diet during both the nymphal and adult stages, developmental times were prolonged, and the net repro ...
