What are the common pests of pomegranate trees
What are the common pests of pomegranate trees? Please introduce the following kinds of pomegranate pests: Japanese tortoise wax scale, commonly known as scale insects, belonging to Homoptera, Coccidae. When the nymph is fixed on the leaves or shoots, it absorbs sap and secretes mucus, which induces coal pollution, affects photosynthesis, weakens the tree potential, causes a large number of fallen leaves and fruit, and in serious cases can lead to sterilization or even death of the whole tree. Prevention and control methods: (1) chemical control. It is a favorable time for chemical control from nymph hatching to wax shell formation; in production, the damage can be controlled by spraying 1000 times of 25% imidophos, 1000 times of 50% malathion, 400 times of 50% carbaryl wettable powder or 1000 times of dichlorvos EC every 7-10 days for 2-3 times. (2) protect and utilize natural enemies. There are many kinds of natural enemies of Japanese tortoise wax scale, such as ladybugs, lacewings, parasitic wasps and so on. Pomegranate stem window moth, also known as pomegranate window moth, occurs in most pomegranate producing areas in China. Larvae drill into new shoots and perennial branches, which weakens the tree potential, affects fruit yield and quality, and can cause death of the whole plant in serious cases. Control methods: (1) in the pomegranate growing season, often check the branches, find the killed new shoots, cut off the branches from the lower end of the last faecal hole in time, and eliminate the larvae. (2) Pesticide control. In the peak incubation period, spray control with 1000 times of Diema mixture, 1000 times of dichlorvos EC or 2.5% of 3000 times of enemy kill, and the effect is good. After the larvae have eaten into the branches, they can use tools such as waste syringes to inject 400-500 times of dichlorvos into the insect track, or dip dichlorvos with cotton balls into the bores, seal the yellow mud and kill the larvae.
