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 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 کاملFitness Costs of Thermal Reaction Norms for Wing Melanisation in the Large White Butterfly (Pieris brassicae)
The large white butterfly, Pieris brassicae, shows a seasonal polyphenism of wing melanisation, spring individuals being darker than summer individuals. This phenotypic plasticity is supposed to be an adaptive response for thermoregulation in natural populations. However, the variation in individuals' response, the cause of this variation (genetic, non genetic but inheritable or environmental) ...
متن کاملPlants influencing the behaviour of Large White Butterfly (Pieris brassicae L
Large White Butterfly, Pieris brassicae L. (LWB) is one of the greatest pests of cruciferous cultures in Estonia, and, in the years of its biggest abundance, it can destroy a significant part of a crop. Many plants contain natural compounds that can repel and/or attract insects and protect neighbouring plants. This principle is used in a method known as companion planting. The aim of this paper...
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...
