[0002] Cherry Drosophila is an important pest that has been found in recent years to harm cherry fruits. Its degree of harm is similar to that of peach fruit borer in the mid-1980s. The variety has reached more than 80%, and the commercial rate of sweet cherries has declined after being damaged, which has seriously affected the selling price and benefits of sweet cherries. Its harm has caused great economic losses to sweet cherries. The damage rate is increasing year by year. From the surface, the fruit insects appeared in late May, and the insect fruit rate continued to rise. In June, with the increase of mature varieties and the increase of fruit maturity, the damage gradually increased, and the concentration of contiguous cherries occurred more Seriously, because the insect only harms ripe or rotten fruits, the higher the maturity, the more serious the harm. In addition, the eggs of this insect are laid in the fruit peel, and after the eggs hatch, the larvae eat the fruit pulp, so the eggs and larvae are directly treated Chemical control is neither reliable nor realistic, and considering the safety of the fruit, it is not suitable to spray pesticides at this stage.
