ABSTRACT

Heliothis/Helicoverpa species have been reported to occur globally, except in the nearctic and neotropical regions (Knuston and Nagarkatti 1989). The need for international collaborative research on biological control of these pests has been well documented by Jackson et al. (1989). The present chapter focuses on the recent progress made in the use of entomophagous arthropods (parasitoids and predators) in biological control of Helicoverpa armigera (Hubner) and discusses the bottlenecks as well as opportunities for promoting biocontrol of this widely distributed and highly polyphagous pest.
