Indole-3-acetonitrile production from indole glucosinolates deters oviposition by Pieris rapae.
Like many crucifer-specialist herbivores, Pieris rapae uses the presence of glucosinolates as a signal for oviposition and larval feeding. Arabidopsis thaliana glucosinolate-related mutants provide a unique resource for studying the in vivo role of these compounds in affecting P. rapae oviposition. Low indole glucosinolate cyp79B2 cyp79B3 mutants received fewer eggs than wild type, confirming p...
متن کاملThe Genome of Pieris rapae Granulovirus.
Pieris rapae granulovirus (PrGV) can infect and kill larvae of Pieris rapae, a worldwide and important pest of mustard family crops. The PrGV genome consists of 108,592 bp, is AT rich (66.8%), and is most structurally and organizationally similar to the Choristoneura occidentalis granulovirus genome. Of the predicted 120 open reading frames (ORFs), 32 genes specifically occurred in GVs, includi...
متن کاملExperimental Evaluation of Arthropod Predation on Pieris rapae (Lepidoptera: Pieridae) Eggs and Larvae in Cabbage
Knowledge of factors causing mortality in herbivorous insects is essential to developing a better understanding of their population dynamics and more effective strategies to manage their abundance in crops. In this study we used 2 methods of predator exclusion to evaluate the effects of arthropod predators on Pieris rapae L. eggs and larvae on cabbages (Brassica oleracea variety capitata L.) in...
متن کاملEffectiveness of the defence mechanism of the turnip sawfly, Athalia rosae (Hymenoptera: Tenthredinidae), against predation by lizards.
The turnip sawfly, Athalia rosae Linnaeus, is a pest on cruciferous crops. Larvae sequester secondary plant compounds, namely glucosinolates, in their haemolymph. When attacked, their integument is easily disrupted and a droplet of haemolymph is exuded ('easy bleeding'). This has been shown to be an effective, chemical-based, defence against invertebrate predators. The efficiency of this propos...
متن کاملIntroduction and evaluation of Cotesia rubecula, a parasitoid of Pieris rapae in New Zealand
The host specificity of Cotesia rubecula (Marshall) was examined through literature searches, behavioural and ecological observations, and host specificity tests of a South Australian population. The results led to the importation and testing of C. rubecula in quarantine in New Zealand where its specificity to the genus Pieris was confirmed. Introduction of the parasitoid was approved and the s...
