Figure 3. Specific mulberry leaf volatiles repel egg parasitoids.
Two oviposition stimulants (α-humulene and valencene) repelled T. chilonis. Mulberry leaf volatiles and two oviposition stimulants (α-humulene and valencene) were presented to egg parasitoids in a 4-arm olfactometer assay. Egg parasitoids were repelled by these oviposition stimulants. Significant difference was analyzed by paired t-test (see Results). Leaf image was taken by V.K.
