Abstract: This experiment revealed that the cavader of Culex pipiens pallens larvae play a role of special culture medium for the Bacillus shaericus regardless in the clean or polluted water. The amount of B. S. spore declined to a lower point after 24 hr when the larvae feed the spore. After that, the amount increased and reached the peak at 96 hr and showed the high toxic against the mosquito larvae of Culex pipiens pallens. However, because the size of most breeding place of this mosquitoes are so large, this phenomenum without any applicable significance to control the breeding places of Culex pipiens pallens.
