Abstract:In studies of the nuclear polyhedral virus residue, we observed that the larvae of Hellothis spp. did little feeding on leaf disks made from cotton leaves (cultivar Stoneville 7A) that had been sprayed with a mixture of toxaphene and DDT. Our observations suggested that this mixture deterred larval feeding. A mixture of toxaphene and DDT has been evaluated as a toxicant against larvae of the bollworm, Heliothis zea (Boddie), and the tobacco budworm, H. virescens (F.), in the laboratory (Adkisson 1967, Adkisson and Nemec 1967) and in the field (McGarr and Chapman 1963, McGarr 1968). Young and Hamm (1966) tested the polyhedral virus separately and in combination with DDT as a control for bollworms (corn earworms) on sweet corn. They found the control of bollworm larvae did not usually increase appreciably when 100 larval equivalents of virus were used in combination with DDT at 2 lb/acre compared with the control achieved when DDT was used alone. However, in 1 test, the virus with DDT did give a significant difference in yield over virus alone. We therefore tested toxaphene and DDT separately and in combination in the laboratory to corroborate the apparent antifeeding effect observed in the field.
