Figure 3. Schematic representation of the response of flies with different rearing histories towards γ-octalactone. B. dorsalis was reared on 3 different hosts.

The final (third) generation gravid females were used in oviposition bioassays. A one-tailed t test revealed a significant difference (P<0.0001) between Test (OL, γ-octalactone present) and Control (No OL, γ-octalactone not present). One-way ANOVA between the tests of group 1 (mango), 2 (banana) and 3 (guava) showed no significant difference in the mean no. of eggs laid.
