pod borer is one of the main causes for yield loss of chickpea. therefore, breeding of chickpea for resistance to this pest is important. the use of cry toxin from bacillus thuringiensis is an effective strategy for producing of transgenic resistant chickpea to this pest. these toxins are able to become active in the midgut of larvae and disrupt the insect's digestive system. we studied the sta...

Efforts are being made to express toxin genes from the bacterium, Bacillus thuringiensis (Bt) in chickpea for minimizing the losses due to the pod borer, Helicoverpa armigera. However, there is an apprehension that acidic exudates in chickpea leaves may influence the protoxin-toxin conversion in the insect midgut, and thus, reduce the efficacy of Bt toxins. Therefore, we studied the influence o...

Article history: Received on: 15/05/2015 Revised on: 10/06/2015 Accepted on: 17/06/2015 Available online: 20/06/2015 Two field experiments were conducted during Kharif, 2010 and 2011 to find out economical control measures against legume pod borer, Maruca vitrata (Geyer) on pigeonpea. Experimental results showed that the per cent inflorescence damage due to Maruca was lowest in chlorantranilipr...

Plant resistance is a promising control method for the two most damaging insect pests of maize, Zea mays L.: the European corn borer, Ostrinia nubilalis (Hübner), and the western corn rootworm, Diabrotica virgifera virgifera LeConte. Fifteen experimental lines of maize, derived from a backcross breeding program designed to introgress resistance to European corn borer from Peruvian maize into tw...

Abstract The evolution of resistance to the Bacillus thuringiensis ( Bt ) toxins by insect pests is a major threat technology. However, rate can be slowed with appropriate integrated management (IRM) strategies. Surveys were conducted identify alternate host species for Maruca vitrata (commonly called legume pod borer or that could serve as refuges Pod-Borer Resistant (PBR) cowpea in three West...
