Abstract Adult H. armigera were tested using a four-choice olfactometer to see how they orientated in response to volatiles from marigold, tomato, chickpea, and pigeonpea plants. Both female and male H. armigera moths were found to be most attracted to the volatiles of marigold plants, with a 35.01 percent attraction to uncut twigs and a 42.32 percent attraction to cut twigs, respectively. The volatile compounds from tomato plants elicited the second highest reaction. Volatiles from the host plant were identified using GC-MS testing. Eleven volatile compounds were isolated from marigolds, ten from tomatoes, seventeen from pigeonpeas, and ten from chickpeas.
