Attractant for coccinella septempunctata

Abstract

The invention provides an attractant for coccinella septempunctata. The attractant for the coccinella septempunctata consists of the following raw materials: 280 to 370 grams of triple superphosphate, 50 to 67 grams of diammonium and 21 to 30 grams of plant ash, wherein the ash rate of ramie root to tamarix to diversifolious poplar in the plant ash is 1:1:1. The attractant for the coccinella septempunctata is prepared by the following steps of: crushing the triple superphosphate and the diammonium into powder; mixing the power and the plant ash; and adding 18 to 35 kilograms of water to stir uniformly and spraying the mixture. The attractant for the coccinella septempunctata is sprayed for twice every year and aims to induce the coccinella septempunctata and kill aphids in the cotton field, wherein the first spraying time is from the twelfth day to the fifteenth day in June and germinated fruit branches of cotton is protected from being infringed by the aphids; the second spraying time is from the twenty-eighth day in July to the first day in August and cotton bolls are protected from being infringed by the aphids; and the spraying temperature is between 28 and 30 DEG C. By the attractant, the yield of the cotton can be increased by 60 to 80 kg / mu. When the attractant is sprayed on melon and fruit, vegetable, red date trees, walnut trees, Pyrus sinkiangensis trees and apple trees, the technical effect of inducing the coccinella septempunctata to kill the aphids is achieved.

Description

technical field [0001] The invention relates to the technology of killing aphids, which lures the seven-spotted ladybug so that it can arrive at a designated position on time, and kills the aphids without using other pesticides; the spraying equipment can be an ordinary pesticide equipment. Background technique [0002] Ladybug is known as a natural enemy of aphids for a long time, but killing aphids often requires the cooperation of pesticides. In order to prevent aphids from invading cotton plants, early practical pesticides are the best choice, which will inevitably cause pesticide poisoning harm to people. In order to prevent insects and control insects to produce the same technical effect, the attractant adopted in the present invention's concept induces the method of Copteris seven-spotted ladybug to kill aphids. [0003] According to research and field observations, aphids usually occur in June (large cotton fields in arid areas) and become a disaster in July. At thi...
