The invention discloses a photo-induction mosquito-removing device for inducing and killing mosquito larva outside, which comprises a cylinder body, an egg-laying chamber, a column, an insectarium, an eclosion chamber, an upper filter and a shield, wherein the column top of the egg-laying chamber is provided with a mosquito-induction opening, and the bottom wall at the bottom is provided with an air chamber; and the egg-laying chamber is inserted into the water from the opening of the cylinder body, and can float up and down. Rain enters the cylinder body through the upper filter on the top of the cylinder body, and forms flooded water in the insectarium and the egg-laying chamber. Female mosquitoes fly into the egg-laying chamber through mosquito-induction opening from the holes on the filter of the cylinder body, and lay and breed wigglers on the surface of the water. The wigglers are naturally active, and enter the insectarium through the meshes of the column for living. Because the temperature of the water in the egg-laying chamber is little high, the wigglers can not swim back and escape. The wigglers find food and pupate in the insectarium. The mosquito larvae begin eclosion into mosquitoes which are trapped in the eclosion chamber, and the breeding chain is cut off. The device can be arranged in a balcony or a garden. Besides, the cylinder body can be used for planting flowers or fishing. People not only can enjoy the joy of gardening, but also can control mosquito breeding, and can create a healthy and comfortable community.

The invention belongs to the technical field of biological prevention and control of sanitary insect pests, and mainly discloses a material and a method for preventing and controlling larvae of mosquitoes which are the leader of 'four pests'. The invention discloses a novel strain Bt S2160-1 of Bacillus thuringiensis, Bt for killing mosquito larvae, wherein the preservation number of the novel strain is CGMCC No.13274. The strain Bt S2160-1 has very high insecticidal activity upon larvae of culex fatigans and aedes albopictus, and compared with a Bt mosquito strain Bti recommended by WHO (World Health Organization), the Bt S2160-1 has relatively high activity upon larvae of aedes albopictus. The Bacillus thuringiensis Bt S2160-1 disclosed by the invention can be made into an insecticide for large-scale prevention and control on larva populations of culex fatigans and aedes albopictus. Therefore, the strain can be powerful supplement as a mosquito control microbial agent in addition to Bti, or even can be used as a substitution of Bti for controlling populations of aedes albopictus, and the risk that mosquitoes have resistance to a Bti crystal protein which is used for a long time to control mosquito populations can be reduced.
