Abstract
Egg counts were made to determine preferred oviposition sites of Heliothis zea (Boddie) on the tomato cultivars ‘VF-J98’ under field cage conditions and ‘VF-198’ and ‘Campbell 82’ under natural conditions. A phenological study of tomato was used to establish an age basis for vegetative and fruiting structures. Moths demonstrated a highly significant preference for oviposition on leaves rather than on blooms, fruit, or stems. No preference was shown for dorsal vs. ventral leaf surfaces. A highly significant relationship existed between proximity of leaves to blooms, with a positive correlation between the number of open flowers and selection of a leaf for oviposition.
