Abstract:
... Heliothis virescens (F) is a polyphagous pest on cotton soybean, and tobacco and H. subflexa (Guenee) is a monophagous nonpest on Physalis spp. Oviposition choices of the reciprocal F1 hybrids of these two species were compared with those of the parental strains to determine sex linkage, quantify niche breadth, and rank host preferences. Strains of H. virescens, H. subflexa, and the reciprocal F1 ...

Abstract:
... We investigated the relationship between parasitoid attraction to herbivore‐induced plant volatiles and larval parasitism rates of two closely related heliothine, noctuid moths. Heliothis subflexa Guenee is a specialist on plants in the genus Physalis, while Heliothis virescens Fabricius is an extreme generalist. In North America, these species serve as the only known hosts for the specialist para ...

Abstract:
... 1. The insect Heliothis subflexa Guenée is a specialist on plants in the genus Physalis. In the present study, the physical response of Physalis leaves to egg deposition by H. subflexa is described. 2. It was observed that the leaves of Physalis plants respond to the eggs of H. subflexa, while co‐occurring non‐host plants do not. Leaves of Physalis angulata L. and Physalis pubescens L. respon ...
