Reader Xue Min, Xiayou Town, Lintong District, Weinan City, Shaanxi Province, China Answer: Spotted wax beetles are common in all parts of the world. The worm eats grapes, skunks and bitter bucks. Adults and nymphs suck the young leaves and stem sap, and the excretion liquid adheres to the leaves and fruits, causing coal pollution and making the surface dark, affecting photosynthesis and reducing the quality of fruit. The worm spends one generation per year, wintering on the twigs and strains of vines. Overwintering eggs usually begin to hatch in mid-April. Adult nymphs appear about 60 days after nymphs. Adults and nymphs are clustered and often harmed on the back of young leaves. They have strong jumping power and are frightened to escape. Eggs are produced in the shade of branches and poles. To control this pest, first, it is necessary to combine Winter pruning to search for egg pieces on the branches and piles for crushing and killing. Second, nymphs and adults can be sprayed with 10% imidacloprid 2000 times or 20% fenvalerate 1500-2000 times. Third, the establishment of the park should be away from miscellaneous woods such as skunk and bitter buckwheat.
