[0011] Determination of biological activity of different insecticides on Drosophila

[0012] Indoor pesticide screening for lethal effects on Drosophila adults

[0013] The lethal action test of fruit flies was carried out by the drug film method, and the results of the investigation are shown in Table 1. In the test agent, 10% pyriproxyfen suspension concentrate has the best effect on fruit fly adults. When diluted 800 times, after 24h, the adults The mortality rate of adult insects is 92%, followed by 4.5% beta-cypermethrin microemulsion and 10% bifenthrin microemulsion, the mortality rate of adults is 85.71% and 86.50% respectively, and the killing rate when 20% diflubenzuron suspension concentrate is diluted 800 times The worm effect was slightly lower than that of the previous pesticides. After 24 hours, the mortality rate of adults still reached 75.61%.

Abstract

The invention relates to a method for preventing and controlling grape sour rots by pesticides. The method is characterized in that four pesticides including pyriproxyfen, beta-cypermethrin, bifenthrin and diflubenzuron are adopted to treat fruit clusters or trap and kill fruit bat flies from a grape veraison to a grape maturation period to prevent and control the grape sour rots.

Description

technical field [0001] The invention relates to a method for preventing and controlling grape sour rot by using insecticides, in particular to using any one of pyriproxyfen, beta-cypermethrin, bifenthrin and diflubenzuron to prevent and control grape sour rot . Background technique [0002] Grape sour rot is an important disease of grape fruit during the ripening period. It is a fruit rot disease caused by the joint action of wounds, fruit flies, pathogenic bacteria and other factors. It is also called secondary infection disease. It is first caused by hail, birds Under proper conditions, more acetic acid bacteria or yeast can grow in the wound, and the yeast can convert the sugar in the fruit pulp into ethanol, and then the acetic acid bacteria will oxidize the ethanol into Acetic acid, the smell of acetic acid lures vinegar flies, and then the vinegar flies carry out a series of activities such as feeding and laying eggs on the wound, and become carriers and disseminators...
