Diapause The facultative diapause in H. Our confidence in the modelled potential distribution presented here is bolstered by the similar distribution of the closely-related H. This dataset consists of long-term monthly average values for minimum temperature, maximum temperature, precipitation, and helicvoerpa humidity at and hr. Insecticide resistance of Helicoverpa armigera to endosulfan, carbamates and organophosphates: For ground nesting animals that are able to regulate their temperature environment somewhat, daily average temperatures can limit the ability of a population to persist [ 62 ].

Suppression of cotton bollworm in multiple crops in China in areas with Bt toxin-containing cotton. Although larvae can feed and survive embtapa leaves of many hosts [ 15 ], they move to [ 282930 ], prefer to feed on [ 31 ], and do better in terms of survival, subsequent fecundity and other fitness parameters when feeding on flowers and fruit e.

Journal of Pest Science. Published online Mar The results of this process for each of the irrigation scenarios were combined, drawing on the results for the irrigated scenario where the GMIA5 dataset indicated that irrigation was practiced, and the natural rainfall scenarios elsewhere.

Helicoverpa assultaH.

They were introduced to control native lepidopteran pests such as H. However, the existing distribution data is mostly imprecise, and hence the known and potential distribution maps should be treated as indicative.

Host plant flowering increases both adult oviposition preference and larval performance of a generalist herbivore. Within the irrigation scenarios, the results of the with- and without diapause models were combined, taking the maximum EI value for each cell, reasoning that the allele that was best adapted to the climate within each cell would predominate.
