Laboratory evaluation of the pathogenicity of three entomopathogenic nematodes against larvae of cabbage butterfly, Pieris brassicae Linnaeus (Lepidoptera: Pieridae)
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 ...
متن کاملBiochemical characterization of digestive proteases of Pieris brassicae (Lepidoptera: Pieridae) feeding on cruciferous hosts
Pieris brassicae is one of the most serious pests of cultivated crucifers in the world. The present experiment is intended to determine the proteolytic digestion of fifth instar larvae and the effects of four cruciferous hosts to P. brassicae nutritional physiology. Brassica oleracea var. botrytis, Brassica oleracea var. capitata, Brassica oleracea var. italica and Brassica oleracea var. viridi...
متن کاملCharacterization of a Digestive α-Amylase in the Midgut of Pieris brassicae L. (Lepidoptera: Pieridae)
The current study deals with a digestive α-amylase in the larvae of Pieris brassicae L. through purification, enzymatic characterization, gene expression, and in vivo effect of a specific inhibitor, Acarbose. Although α-amylase activity was the highest in the whole gut homogenate of larvae but compartmentalization of amylolytic activity showed an equal activity in posterior midgut (PM) and ante...
متن کاملEffects of a lectin from Polygonum persicaria L. on Pieris brassicae L. (Lepidoptera: Pieridae)
In the current study, the entomotoxic effects of a lectin, extracted from Polygonum persicaria, were determined on Pieris brassicae larvae. The purified molecule significantly decreased larval survival, weight, and mass protein. Different concentrations of P. persicaria agglutinin (PPA) (0.5, 1 and 2 mg/ml) significantly decreased nutritional indices including: the efficiency of conversion of i...
متن کاملترکیبهای محافظ سرما در شفیره‌های آزمایشگاهی و زمستان‌گذران سفیدۀ بزرگ کلم Pieris brassicae (Lepidoptera: Pieridae)
سفیدۀ بزرگ کلم Pieris brassicae (L.)، از آفات مهم گیاهان خانوادۀ چلیپاسانان بوده که به‌صورت شفیره روی گیاهان مختلف یا دیگر پناهگاه‌ها، زمستان را پشت سر می‌گذارد. در زمینۀ تغییرپذیری فیزیولوژیکی این آفت در طول زمستان که آن را در برابر دماهای پایین متحمل می‌سازد اطلاعات کمی در دست است. لذا در این بررسی، ترکیب‌های محافظ سرما در حشرات گردآوری‌شده در ماه‌های پاییز و زمستان و همچنین شفیره‌های آزمایشگ...
