The importance of Heliothis has grown with the advent of resistance in H.armigera to various pesticides.

Outbreaks of native budworm, Helicoverpa punctigera, often arise after egg laying by emigrant moths from distant populations.

The Australian cotton industry relies heavily on chemical pesticides for management of a diverse array of pest insects, weeds and diseases.

During the 1988/89 cotton season trials were conducted to evaluate the potential of synthetic pheromones to control the pink -spotted boll worm, Pectinophora scutigera, by mating disruption

The aim of the present work was to assess if the fatty acid profiles of moths are useful in establishing different larval dietary histories
