文摘
- •
We studied the effects of dual herbivory on three different parasitoid species.
- •
Egg and caterpillar parasitoid foraging were affected by aphid nonhosts.
- •
Foraging by aphid parasitoids was not affected by the presence of nonhost caterpillars.
- •
For all three wasp species there was a negative, aphid density-dependent effect.
- •
Plant volatile emissions respond nonlinearly to increasing aphid density.
