Hybridizing transgenic Bt cotton with non-Bt cotton counters resistance in pink bollworm.
Extensive cultivation of crops genetically engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) has suppressed some major pests, reduced insecticide sprays, enhanced pest control by natural enemies, and increased grower profits. However, these benefits are being eroded by evolution of resistance in pests. We report a strategy for combating resistance by cro...
متن کاملEfficacy of Some Insecticides Against Whitefly (Bemisia tabaci Genn.) Infesting Cotton under Field Conditions
Seven insecticides, viz. Megamos 20SL, Actara 25WG, Polo 500SC, Sitara 25WP, Nighaban 20EC, Thiodan 35EC and Confidor 200SL were evaluated at their field recommended doses for their efficacy against whitefly (Bemisia tabaci Genn.) on cotton, at the farmer’s field in Dera Ghazi Khan during 2007. The insecticides were applied at ETL’s of whitefly. All the test insecticides caused significant mort...
متن کاملGenetics of resistance to cotton leaf curl disease in Gossypium hirsutum L. under field conditions.
One hundred and forty two cotton germplasm lines were screened for cotton leaf curl virus symptoms in field evaluations during 2003, 2004, and 2005. Fifty cross combinations involving 30 of these lines classified resistant or susceptible were used for inheritance study of the disease. All the F(1) plants of crosses involving resistant x resistant, resistant x susceptible, and susceptible x resi...

Epidemiological studies were undertaken at slaughter-houses, livestock farms, veterinary hospitals andon household buffaloes under climatic conditions of four different districts of Punjab province. Infection ratewas 22.29, 28.33, 17.08 and 12.75%, respectively in slaughter-house buffaloes, livestock farm buffaloes,veterinary hospital buffaloes and household buffaloes. Overall the season wise t...
متن کاملDominant resistance to Bt cotton and minor cross-resistance to Bt toxin Cry2Ab in cotton bollworm from China
Evolution of resistance by insect pests threatens the long-term benefits of transgenic crops that produce insecticidal proteins from Bacillus thuringiensis (Bt). Previous work has detected increases in the frequency of resistance to Bt toxin Cry1Ac in populations of cotton bollworm, Helicoverpa armigera, from northern China where Bt cotton producing Cry1Ac has been grown extensively for more th...
