Abstract:

A biological control program for Heliothis species on cotton consisting of the naturally occurring predator-parasite complex and the nuclear polyhedrosis virus was integrated into a cotton-insect-biological-control program. Heliothis control with biological agents was compared with a toxaphene.DDT-1llethyl parathion control program using 25-30acre plots. The virus was applied at 1.2X1011 (20 Lu), 30x1011 (50 LU), and 6,OXI1011(100 LU) polyhedral inclusion bodies (PIBs) per acre. The initiation of virus applications was varied to evaluate the effectiveness of the virus against various ages of larvae, The Heliothis biological control program compared favorably with the insecticide program when virus application was initiated to coincide with hatch of high egg populations.
