| documentation of high-level bacillus sphaericus 2362 resistance in field populations of culex quinquefasciatus breeding in polluted water in thailand. | bacillus sphaericus (bsph) neide has been recognized as an effective mosquito larvicide since its discovery 20 years ago. various strains of this agent, such as 2362, 2297, 1593, and c3-41, have been developed, formulated, and field-evaluated against mosquito larvae in different countries. their high efficacy in controlling mosquitoes breeding in various habitats, especially those in polluted water, has been documented. however, resistance to bsph has been reported in culex pipiens complex in bo ... | 2004 | 15669382 |
| emergence of resistance and resistance management in field populations of tropical culex quinquefasciatus to the microbial control agent bacillus sphaericus. | in recent years, highly potent mosquitocidal strains of the microbial agent bacillus sphaericus (bsph) have been isolated and developed for the control of mosquito larvae around the world. laboratory selection experiments with the most active strains and their use in large-scale operational mosquito control programs resulted in the emergence of resistance in larvae of the culex pipiens complex. this generated great concern among vector control agencies around the world, who feared reduced effica ... | 2003 | 12674533 |
