The Heliothine complex, Helicoverpa zea (Boddie) and Helicoverpa virescens (F.), is considered the second most important insect pest group in Virginia, thrips being the primary pest. It is estimated that Heliothines caused a total yield loss of 2,937 bales, or about 590 bales per year, in the years from 1997-2001. Each year, several field experiments are conducted at Virginia Tech research farms to evaluate efficiacy and efficiency of different products/rates and application strategies. Bollworm resistance has been monitored using adult vial testing procedures during the 2000 and 2001 seasons. Heliothine eggs collected from commercial cotton fields were tested with the Helid egg testing system to determine the species ratio of the bollworm:budworm complex. Results showed that all products did not result in the same lint yields, and that using the high rate at the second application generally resulted in more lint than applying two sequential lower-rate sprays. In vial testing studies, in 2000, over all sample dates and locations, 12 and 6% of bollworm adults survived the 5 and 10µg cypermethrin rates, respectively. In 2001, over all sample dates and locations, only 3.3 and 0% survived the 5 and 10µg cypermethrin rates, respectively. Only 2.2% survived the 15µg spinosad rate. The ratio of bollworm:budworm eggs varied over the five-sample date period with bollworm comprising 67-95% of the egg population, depending on sample date. Over all sample dates, the bollworm:budworm egg ratio was 78:22%.
