Pear moth mainly harms peach fruit and new shoots. It overwinters with mature larvae in cracks in the old bark of the host trunk, at the root neck, beside rocks and orchards. Usually, the first and second generation larvae occur from mid-May to late June, which mainly harms the new shoots of peach trees. Damaged shoots often shed gum, and the leaves withered first, then dried up and drooped. From mid-July to late August, the 3rd and 4th generation larvae occurred, which mainly harmed the peach fruit. Larvae mostly feed from the depression of the fruit stalk and feed on the core of the fruit, and the damaged fruit is easy to rot and fall off.

Prevention and control methods: ① Scrape off the old bark. From winter to germination, all the old bark of branches is scraped off and burned centrally to eliminate overwintering larvae. (2) Cut off the tips of pests. When it is found that the leaves of new shoots 1 ~ 2 are withered, the damaged new shoots should be cut off in time, and the larvae in them should be treated and destroyed centrally. ② Trapping and killing adults. At night, put the sweet and sour liquid (brown sugar 1, vinegar 2, water 10, a little white wine) into the jar and hang it on the peach tree to trap and kill the adults. ④ Chemical control. When the rate of eggs and fruits in the field reaches 65438 0%, it should be sprayed in time. The available chemicals are 50% acetaminophen EC 1000 times, 2.5% fenvalerate EC 2500 times, 20% methomyl EC 2500 times and 50% phoxim EC 1000 times. In the larval stage, 25% diflubenzuron 3 can also be sprayed with 2000 times solution, and the effect is very good.
