The increasing need for food can be met through an increase in crop productivity and reduction in pest associated losses. Recombinant DNA technology has created new avenues for genetic enhancement of crops through the development of transgenic plants with resistance to insects. Bacillus thuringiensis (Bt) genes have been widely used as candidate genes for genetic transformation of crop plants f...

Development of resistance and resurgence has limited the application of single pesticide and has given way out to tank mixture. Pest management strategy is mainly relying on chemical pesticides. Mixture of two or more pesticides is very common among the farmers. Pest population to be controlled should be susceptible or have low level of resistance to each pesticide used in the mixture. Combinat...

BACKGROUND The noctuid Helicoverpa armigera is one of the key cotton pests in the Old World. One possible pest regulation method may be the management of host crop in the landscapes. For polyphagous pests such as H. armigera, crop diversity and rotations can offer sequential and alternate resources that may enhance abundance. We explore the impact of landscape composition and host crop diversit...

Diamondback moth (DBM), Plutella xylostella (L.), has attained major pest status in Brassica vegetable crops around the world. In many cases, use of synthetic pyrethroid insecticides for control of other pests, such as Pieris rapae (L.), has disrupted natural enemies and selected for insecticide resistance in DBM, changing the pest status of the moth from minor to major. We estimated levels of ...
