Formulation for optimizing Bacillus thuringiensis production

Publikováno v: Journal of Biological Control. 31:38-49

Bacillus thuringiensis Berliner, a gram positive aerobic bacterium, produces parasporal crystal (Cry) toxins that are highly specific and effective against insect species. During the course of isolation of native strains, B. thuringiensis AUG-5 was f

Genetically Modified Crops in Asia Pacific

Autor: Mao Chen, G T. Gujar, Y Andi Trisyono

Meeting future food needs without compromising environmental integrity is a central challenge for agriculture globally but especially for the Asia Pacific region – where 60% of the global population, including some of the world's poorest, live on o

Cooperative management of pest susceptibility to transgenic Bacillus thuringiensis (Bt) crops is pursued worldwide in a variety of forms and to varying degrees of success depending on context. We examine this context using a comparative socioecologic

Rising levels of antimicrobial and pesticide resistance increasingly undermine human health and systems for biomass production, and emphasize the sustainability challenge of preserving organisms susceptible to these biocides. In this Review, we intro

Toxicity of Bacillus thuringiensis Cry2Ab and the inheritance of Cry2Ab resistance in the Pink bollworm, Pectinophora gossypiella (Saunders)

Autor: P A, Malthankar, G T, Gujar

Publikováno v: Indian journal of experimental biology. 54(9)

Though the insecticidal crystal (Cry) proteins produced by Bacillus thuringiensis (Bt) are effective against insect pests, evolution of resistance remains an issue of great concern. Here, we explored the ability of pink bollworm, Pectinophora gossypi

Publikováno v: Annals of Microbiology. 65:611-629

The diversity of culturable, aerobic and heterotrophic Bacillus and Bacillus-derived genera (BBDG) was investigated in various extreme environments (including thermal springs, cold deserts, mangroves, salt lakes, arid regions, salt pans and acidic so

Field-evolved resistance to Bt toxin Cry1Ac in the pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), from India

Autor: Sanyasi Dhurua, G. T. Gujar

Publikováno v: Pest Management Science. 67:898-903

BACKGROUND: The pink bollworm is one of the most destructive pests of cotton. Transgenic cotton producing Bt toxin Cry1Ac or a combination of Cry1Ac and Cry2Ab2 has been used effectively against this pest. However, some other insects have evolved res

Impact of different levels of non-Bt cotton refuges on pest populations, bollworm damage, and Bt cotton production

Autor: G. T. Gujar, S. Dhurua, G. K. Bunker, V. Kalia

Publikováno v: Journal of Asia-Pacific Entomology. 13:249-253

The impact of structured strip row refugia (varying from 10% to 50%) in the Bt cotton crops JKCH1947Bt (producing one toxin, Cry1Ac) and MRC7017BGII (producing two toxins, Cry1Ac and Cry2Ab) on the pest complex and cotton yield was studied. During th

Autor: K.K. Aggarwal, G. T. Gujar, V. Kalia, Rupa Nair

Publikováno v: Journal of Invertebrate Pathology. 104:31-38

The analysis of reciprocal genetic crosses between resistant Helicoverpa armigera strain (BH-R) (227.9-fold) with susceptible Vadodara (VA-S) strain showed dominance (h) of 0.65-0.89 and degree of dominance (D) of 0.299-0.782 suggesting Cry1Ac resist
