BACKGROUND:Helicoverpa armigera (Hubner) is one of the most important pests in many countries. Spinosad is used widely for the control of pests, but there is sparse information available regarding its sublethal effects on H. armigera. Here, the autho

Laboratory colonies of cotton bollworm larvae, Helicoverpa armigera, kept at 20 degrees C under a photoperiod of L:D=10:14 were fed on five host plants (cotton, corn, kidney bean, tobacco and tomato) and an artificial diet (control) to determine the

The development, body weight, survivorship, and reproduction of the cotton bollworm, Helicoverpa armigera (Hubner), were evaluated in the laboratory at 27°C and photoperiod L:D = 14:10 on six host plants: cotton (Gossypium hirsutum L.), corn (Zea ma

Summer diapause in the cotton bollworm, Helicoverpa armigera (Hubner), is prolongation of the pupal stage, particularly in males, induced by high temperatures. The effects of exposing a parental generation to temperatures of 33 to 39°C on the develo

A new and practical artificial diet for the cotton bollworm, Helicoverpa armigera (Hubner), containing canned tomato paste has been developed. The developmental duration of larvae fed on the diet was greatly shortened because most of them only went t

Performances of the aphid, Myzus persicae, were monitored during feeding on leaves of the rape, Brassica chinensis, previously fumigated with SO2 in a range of concentrations between 20 and 160 nl/1 at 25°C. Response of the aphids depended on dose o

Facultative diapause, a strategy that allows insects to initiate additional generations when conditions are favorable or to enter diapause when they are not, has a profound effect on the ecology and evolution of species. Most previous studies have co

Laboratory colonies of cotton bollworm larvae, Helicoverpa armigera, were kept at 20 degrees C under a photoperiod of L:D=10:14 and fed on three host plants (cotton, tobacco, kidney bean) and an artificial diet (control) to determine the dynamic effe

Summer diapause in the cotton bollworm, Helicoverpa armigera (Hubner), which prolongs the pupal stage, particularly in males, is induced by high temperatures. In the laboratory, summer-diapausing pupae of H. armigera were induced at high temperatures
