Rearing the Cotton Bollworm, Helicoverpa armigera, on a Tapioca-Based Artificial Diet

The impact of a tapioca-based artificial diet on the developmental rate, life history parameters, and fertility was examined over five consecutive generations for the cotton bollworm, Helicoverpa armigera Hubner (Lepidoptera: Noctuidae), a highly polyphagous pest of many agricultural crops. The study showed that when fed the tapioca-based artificial diet during larval stage, larval and pupal de...

A comparison of artificial diet and hybrid sweet corn for the rearing of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) based on life table characteristics.

The demographic characteristics of Helicoverpa armigera (Hübner) reared on hybrid sweet corn (Zea mays L. variety saccharata) (hybrid super sweet corn KY bright jean) and on an artificial diet were compared by using the age-stage, two-sex life table. Because the hatch rate of eggs varies with maternal age, age-specific fecundity was calculated based on the numbers of hatched eggs to reveal the ...

Increasing tolerance to Cry1Ac cotton from cotton bollworm, Helicoverpa armigera

1. Changes in the frequency of Cry1Ac resistance genes and shifts in tolerance of cotton bollworm, Helicoverpa armigera , to the Cry1Ac toxin were assessed using bioassays of F 1 and F 2 offspring of isofemale lines from Anci County of Hebei Province (a multiple-crop system including corn, soybean, peanut, and Bt cotton) and Xiajin County of Shandong Province (an intensive Bt cotton planting ar...

Rearing the house fly predator Carcinops pumilio (Erichson) (Coleoptera: Histeridae) on an artificial diet

A number of concentrations of PRO-PLEXTM, a protein rich food additive, were incorporated into an artificial diet to determine its effect on the predatory beetle, Carcinops pumilio (Erichson). The impact of this host-free artificial diet on developmental time, larval weight, oviposition and mortality was assessed. When C. pumilio is fed on a host-free diet, the total development of egg to adult...
