Sex-biased predation on moths by insectivorous bats
Article Abstract:
Predation risk from bats which hunt airborne prey apply to all nocturnally flying insects that show sexual dimorphism during flight. The study on two species of insectivorous bats, Lasiurus cinereus and L. borealis shows that they consumed remarkably more male than female moths in the wild. This is due to sexual dimorphism related to sexual differences in mate acquiring technique. The peak of male and bat activity coincide in the middle of the night, but female activity peaked earlier in the night when bat activity is comparatively low.

The influence of genes for melanism on the activity of the flour moth, Ephestia kuehniella
Article Abstract:
The effects of genes for melanism on activity levels and patterns in adult Mediterranean flour moths Ephestia keuhniella, were investigated. Electrostatic techniques were used to measure walking or flight activity of mated females during the third night of their lives. Melanic females were found to be more active that the nonmelanic genotypes, although the average length of bouts of activity were no different.

Experience influences oviposition behaviour in two pyralid moths, Ephestia cautella and Plodia interpunctella
Article Abstract:
A study on the role of experience in oviposition behaviour in pyralid moths is presented. The almond moth (Ephestia cautella) and the Indian meal moth (Plodia interpunctella) were used in the study.
