Studies were conducted at The International Crops Research Institute for the Semi-Arid Tropics, Asia Region, (ICRISAT) during 1999-2000, on the male nocturnal moth, Helicoverpa armigera
, to examine the trapping effectiveness of the "ICRISAT Dry Funnel" pheromone trap design.
Using genetic engineering techniques, a team of Australian researchers has created plant cells which produce a virus that kills a costly agricultural pest, Helicoverpa armigera
, the cotton bollworm.

NPV and Spodoptera litura NPV).

Juss) extracts against American bollworm, Helicoverpa armigera
Bt cotton effectively control bollwsorms, especially Helicoverpa armigera
, thus preventing yield losses from an estimated damage of 30% to 60% each year in India.
1997, "Differentially regulated inhibitor sensitive and insensitive protease genes from phytophagous insect pest Helicoverpa armigera
are members of complex multigene families".
It has been shown that Helicoverpa armigera
moths laid more eggs on the most abundance hosts in field due to increased encounters .
Old world bollworm, Helicoverpa armigera
(Hubner), surveys were initiated in 2004 under the Indiana Cooperative Agricultural Pest Survey (CAPS) program.
These observations agree with those noted by Mironidis & Savopoulou-Soultani (2008), who mentioned that the development of Helicoverpa armigera
(Hubner, 1808) (Lepidoptera: Noctuidae) was faster under an alternating thermal regime (mean 25[degrees]C) than in a constant temperature (25[degrees]C).
Delayed cuticular penetration and enhanced metabolism of deltamethrin in pyrethroid resistant strains of Helicoverpa armigera
