The white star beetle is commonly known as "Mingklun" or "old stuffy". The adults were the most seriously endangered during June-August, and they ate during the daytime. The apples, pears, and peaches that most like to have wounds were eaten. The fruit was bitten into a big hole, causing fruit drop and rot. Adults have a feign death and clustering, and fruit vinegar flavor and sunflower flower dish aroma are highly attractive to adults. Using these characteristics, the following three methods can be skillfully used to control the white beetle, which can save costs and receive ideal control effects without polluting the environment. 1, plant sunflower entice method. In the orchard, 4-6 plants per mu were planted in a single plant. During the months of June to August, using the sunflower scent trap, each morning, a bag of sunflowers was used to cover the sunflower and the adult insects were dropped into the bag, and then concentrated to kill. Each day can kill more than 20 per plant. 2, fruit vinegar trapping method. Use the characteristics of white star beetle like fruit vinegar. The preparation method of fruit vinegar is: 1 part of ground fruit, 1 part of vinegar, 1.5-2 parts of sugar and 0.5 parts of water. The fruit is chopped, mixed with vinegar, sugar, water, heated and boiled into a porridge, into a wide-mouth bottle, half a bottle is better. Then add half a 500-fold dichlorvos solution and mix well. During the peak period of adult white beetle beetles, in the orchard, a bottle of fruit vinegar is suspended at intervals of 20-30 meters, and the height of the bottle is 1.2-1.5 meters. The bottle should be close to the trunk so that the adult insects can fly into it and remove the white beetle's dead insects every morning. 3, insect trap method. Use adult trapping characteristics. In the orchard, evenly distribute beer bottles at a height of 1.5 meters or so, and catch 2 or 3 living white beetle adults into beer bottles. Will recruit other adults to fly into the bottle. When the amount of adults is large, beer bottles can be induced within 3-5 days, and attention should be paid to clearing the adults in the bottles in time.
