| differential selection of malathion resistance in anopheles culicifacies a and b (diptera: culicidae) in haryana state, india. | in november 1989, for the first time after the introduction of malathion spray in 1982, increased densities of anopheles culicifacies giles s.l. were observed in chhatera and barota, two villages in halalpur block in sonepat district, haryana state, india. in bioassay tests against the diagnostic dose of malathion (5% for 1 h), 41-47% of mosquitoes survived. an culicifacies populations in this area comprise two sibling species, a and b. differential malathion resistance was observed; in species ... | 1992 | 1495027 |
| urban malaria and its vectors anopheles stephensi and anopheles culicifacies (diptera : culicidae) in gurgaon, india. | the seasonal variation in the density of immature and adult malaria vectors anopheles stephensi and an. culicifacies were recorded from january to december, 1986 in urban gurgaon, india. the highest combined anopheline larval density (2.3 per dip) was recorded in the 31st week. the peak adult density for malaria vectors an. stephensi (4.14 per man hour) and an. culicifacies (1.02 per man hour) were reported in the month of august. the highest percentage of total infestation for anophelines and o ... | 1995 | 8525407 |
| susceptibility of the malaria vector anopheles culicifacies (diptera: culicidae) to ddt, dieldrin, malathion, and lambda-cyhalothrin. | the susceptibility of the malaria vector anopheles culicifacies to ddt, dieldrin, malathion, and lambda-cyhalothrin was determined in karnal, yamunanagar, and ambala districts of haryana state, india. the vector population showed a high degree of resistance to ddt and dieldrin. the test mortality to ddt and dieldrin ranged from 25% to 28% and 18% to 20%, respectively, in nadasahib of ambala districts. the mortality of an. culicifacies to malathion ranged between 65% and 68%. all the tests with l ... | 1999 | 10672548 |
| evaluation of bifenthrin treated mosquito nets against anopheline and culicine mosquitoes. | the main rural malaria vector anopheles culicifacies has developed resistance to dichloro diphenyl trichloroethane (ddt), hexachloro cyclo hexane (hch) and malathion in the state of haryana in northern india. an alternative synthetic pyrethroid insecticide bifenthrin was therefore evaluated on mosquito nets against anopheline and culicine mosquitoes, in two villages jagdishpur and garh mirakpur of community health center (chc) badhkhalsa in district sonipat, haryana state. | 2005 | 15713980 |
