Abstract: | The temporal occurrence and frequency of mating, oviposition, and feeding of wild velvetbean caterpillar moths, Anticarsia gemmatalis,in a soybean field (Glycine max)were documented. Mating occurred predominately during the first 4 h after sunset and primarily on leaflet bottoms. Oviposition was concentrated within the first 6 hr after sunset. Eggs were laid singly, and in areas of high trichome density, on leaflets, pulvini, and petioles. Feeding occurred primarily at night, with most males feeding during the first half of the night and females during the second half. Males and females shared some food sites but others were visited strictly by males. |
