Granular mosquito larva-killing preparation

Abstract

The invention discloses a granular mosquito larva-killing preparation. The key points of the technical scheme comprise that: the granular mosquito larva-killing preparation consists of an attapulgite ceramsite filter material, an ethanol extract of a botanical pesticide, pasty attapulgite clay and ethanol. The granular mosquito larva-killing preparation is prepared by the following steps of: stirring the raw materials at a low speed; and after the mixed liquid of the ethanol extract of the botanical pesticide, the pasty attapulgite clay and the ethanol is absorbed by the attapulgite ceramsite filter material completely, performing packaging to prepare a finished product, namely the granular mosquito larva-killing preparation. The granular mosquito larva-killing preparation is scattered into mosquito larva-containing water; the ethanol extract of the botanical pesticide and the pasty attapulgite clay absorbed by the attapulgite ceramsite filter material are released and dispersed into the water; and the mosquito larvae deposited into the water bottom are adhered to the dispersed pasty attapulgite clay and are killed by the released ethanol extract of the botanical pesticide, so the granular mosquito larva-killing preparation is suitable for killing the mosquito larvae.

Description

technical field

[0001] The invention relates to a mosquito killer, in particular to a granular preparation for killing mosquito larvae. Background technique

[0002] Summer is the most rampant season for mosquitoes. After being bitten by mosquitoes, "red blood cells" will form on the skin. Bringing some terrible infectious diseases, mosquitoes have seriously affected people's normal life and sleep, endangering human health, and eliminating mosquitoes is the key to ensuring human health and avoiding the spread of diseases.

[0003] The total number of eggs produced by each female mosquito is about 1,000 to 3,000. Mosquitoes lay eggs on the water surface and hatch into aquatic larvae—larvae after two days. Larvae feed on bacteria and single-celled algae in the water. They undergo 4 times of shedding Then it grows into a chrysalis, floats on the water, and finally the chrysalis skin ruptures, and the larvae are born. Therefore, priority is given to killing the larvae of mosqu...
