| dc.description.abstract | Studies were conducted to determine the effect of various biotic and physical factors on the feeding and searching behavior of the larvae of Chrysopa carnea Stephens. The ultimate objective of these studies was to determine the principle factors affecting the number of C. carnea larvae required to control populations of the bollworm, Heliothis zea (Boddie), and the tobacco budworm, H. virescens (F.), on cotton. Studies indicated that survival of C. carnea larvae were affected more by the quantity of the prey than by the kind of prey available. The preference exhibited by C. carnea larvae for the 4 different kinds of prey commonly found in the field was, in descending order: 1st instar Heliothis larvae; cotton aphids, Aphis gossyppii Glover; Heliothis eggs; and carmine spider mites, Tetranychus cinnabarinus (L.). C. carnea larvae were capable of completing development on the 4 different kinds of prey. ... | en |
