Magnet is a blend of synthetic plant volatiles that attracts Helicoverpa moths, especially females. Currently, research is determining strategies to utilize this product in cotton pest management. One strategy is to mix Magnet with synthetic insecticides and use the product as attract and kill (Pyke et al. 1987) on Bollgard ) cotton to reduce Helicoverpa populations on adjacent conventional cotton crops. The study reported here showed that, Magnet mixed with insecticide and applied to Bollgard cotton crops, can reduce populations of Helicoverpa spp. on adjacent conventional cotton crops. The study also showed that using Magnet in this way, growers could reduce insecticide use and costs for control of Helicoverpa spp. on conventional cotton crops
