Durante los años 2016 al 2019 por un período de muestreo 15 días en el mes setiembre la comunidad Claverito, ubicada parte baja plaza Clavero zona oriental y periurbana ciudad Iquitos (Perú), con finalidad monitorear riqueza abundancia mariposas diurnas empleando red entomológica trampas Van Someren Rydon, se registraron 3738 individuos, pertenecientes a 6 familias, 26 géneros 32 especies. La f...

The Black-veined White Aporia crataegi (Lepidoptera: Pieridae) is a trans-Palearctic species causing damage to various fruit and berry crops. Here we analyzed Wolbachia infection in A. populations. bacteria are maternally transmitted intracellular symbionts of many arthropods, including numerous Lepidoptera. We have studied 376 samples collected 10 regions Russia from the Far East Kaliningrad. ...

Abstract Background Cabbage butterfly, Pieris brassicae Linnaeus (Lepidoptera: Pieridae), is a major insect pest affecting cole crops worldwide. Excessive applications of chemical-based insecticides have devastating impression over the organisms and environment. Results In this study, entomopathogenic nematode (EPN) Heterorhabditis bacteriophora Poinar strain EUPT-S26 (local isolate) was evalua...

В научно-исследовательской работе приводится видовой состав чешуекрылых - вредителей сои ТОО «Байсерке-Агро» в Алматинской области. результате проведенных исследований на полях кормовых (соя) культур области нами было отмечено 22 вида (бабочки), относящихся к 6 семействам. По видовому разнообразию из выявленных преобладают представители семейства Noctuidae – 10 видов, за ними следуют Pieridae 4...

The methanolic extract of milk thistle, Silybium marianum L. (Asterales: Asteraceae), was investigated for its effects on the mortality, growth, feeding indices, enzymatic activity, and levels of non-enzymatic molecules of the small white butterfly, Pieris rapae L. (Lepidoptera: Pieridae), a pest of cruciferous plants. Feeding indices including approximate digestibility (AD), efficiency of conv...

Porphobilinogen represents a key building block of tetrapyrroles serving as functional ligands of many vitally important proteins. Here we report the first purification of porphobilinogen synthase (PBGS) from whole insects by sequentially employing two modes of native electrophoresis on polyacrylamide gels subsequent to more conventional procedures. Using adults of Pieris brassicae L. (Lepidopt...

Man's harvesting of photovoltaic energy requires the deployment of extensive arrays of solar panels. To improve both the gathering of thermal and photovoltaic energy from the sun we have examined the concept of biomimicry in white butterflies of the family Pieridae. We tested the hypothesis that the V-shaped posture of basking white butterflies mimics the V-trough concentrator which is designed...

We here report the first complete mitochondrial (mt) genome of a skipper, Ctenoptilum vasava Moore, 1865 (Lepidoptera: Hesperiidae: Pyrginae). The mt genome of the skipper is a circular molecule of 15,468 bp, containing 2 ribosomal RNA genes, 24 putative transfer RNA (tRNA), genes including an extra copy of trnS (AGN) and a tRNA-like insertion trnL (UUR), 13 protein-coding genes and an AT-rich ...

The development of indigenously isolated entomopathogenic nematodes as biological control agents was investigated. The study involved three nematode species (Heterorhabditis indica, Steinernema thermophilum and S. glaseri) and their pathogenicity against larvae of cabbage butterfly, Pieris brassicae, under laboratory conditions. Nematodes of different concentrations (0, 10, 25, 50, 75, and 100 ...
