Heliothis armigera has been a growing problem for many years, While the cotton producers have borne the brunt of it, reports of increasing damage to crops such as pulses, sorghum an maize have become more frequent. The subtropical climate of the Darling Downs, Burnett and Dawson Callide regions along with the number of host crops grown in the region have created a paradise for Heliothis and devastation for field crop growers. The cotton industry has had avoluntary chemical usage strategy for many years, however, due to many of the same chemicals being used on other crops, chemicals are failing because of the continuous exposure of Henothis to the same chemical in different crops e. g. Carbamates on chickpeas, cotton and mung beans. The last 2 summer seasons have seen many chemicals on the verge of failure as the leve of resistance rose with spray failures occurring when application rates and timing were not 100%. There has been little or no margin for error. In December 1997, Downs growers were warned that cotton may become unviable with years If Heliothis armigera was not managed. In some Downs areas in 1996-97 and again in 1997-98 Heliothis egg lays reached up to 800 per meter with very small and small larvae at to 7 per meter during periods of the season. This pressure meant that many grain crops were also at serious risk i.e all pulse crops and unacceptable damage to sorghum, maize, sunflowers and millets. Added to this list of woes was the poor performance of Ingard cotton. This along with very limited new technology available at a prohibitive price, indicated that a cropping Armageddon was fast approaching
