Kairomones and their use for management of entomophagous insects : XI. Effect of host plants on kairomonal activity of frass fromHeliothis zea larvae for the parasitoidMicroplitis croceipes.

abstract：:In nature, Papilio polytes utilizes a limited range of rutaceous plants as hosts. We isolated and identified oviposition stimulants for the butterfly from the foliage of its primary host plant Toddalia asiatica. Females readily deposited eggs in response to a methanolic extract of the plant. Partition of the extract w...
