Logáil Isteach / Cláraigh

To examine how plant allelochemicals in prey affect foraging choices made by generalist predator paper wasps, Polistes dominulus (Vespidae), we compared predation on Pieris napi (Pieridae) caterpillars reared on host plants with different allelochemicals. In naturalistic behavioral choice

Larvae of the cabbage butterfly,Pieris rapae, refuse to feed on the wild mustard,Erysimum cheiranthoides, due to the presence of alcoholextractable deterrents. The active components were extracted inton-BuOH, and this extract was separated into four fractions (I-IV) by reverse-phase HPLC. Fractions

The possible effects of environmental stress on plant chemistry that are important to herbivorous insects were examined by growing a wild crucifer, Erysimum cheiranthoides, under different nutrient regimes. Oviposition by the cabbage butterfly, Pieris rapae, is thought to be affected by the balance
