ABSTRACT
LepTon HTK is a diagnostic test kit currently being developed for differentiating between the eggs of tobacco budworm (Heliothis virescens) and cotton bollworm (Helicoverpa zea). The kit is the product of a joint collaboration between the CSIRO (Australia), Cotton Incorporated, and Abbott Laboratories. Development of the specific antibody was initiated in September, 1995, with an anticipated market introduction during the 1998 cotton field season. Procedures for using the test kit have been identified, along with key recommendations for successful application to egg differentiation. The kit will enable the U.S. cotton grower and consultant to accurately identify insect populations and to select the most effective insecticide for control.
