The white star beetle mainly feeds on the juice and flower discs of the sunflower rhizome with adults. Its prevention and control methods are as follows:

(1) Agricultural control. 1 Severe plots of beetles occur in the late autumn or early winter, which can reduce the damage of the second year. 2 Reasonably arrange the mouthwash. Beans, peanuts, sweet potatoes and corn are white-flowered beetles. Avoid crop rotation with such crops. 3 Avoid using uncooked manure. 4 Reasonable fertilization. Ammonium bicarbonate, ammonium humate, ammonia, ammoniated superphosphate and other chemical fertilizers emit ammonia, which has a certain evasive effect on the white-billed beetle. 5 Reasonable irrigation. Severe plots occur in the white star beetle, and irrigation time is appropriately postponed.

(2) Physical control. 1 Using the characteristics of white star beetle adult beetle cluster damage, the fine-mouthed bottle was hung on the sunflower in the initial period of the white-winged beetle, the bottle or the cleaned waste pesticide bottle can be, the bottle height is 1 to 1.5 meters, and the bottle is put in the bottle. Into 2 to 3 white star beetle adults. When the white-spotted golden tortoise in the field flies to the bottle, it first crawls at the bottle's mouth and falls into the bottle. It can hunt 40 to 50 white-flowered beetles per mu. 2 At the height of adult emergence, white wine, brown sugar, vinegar, water and 90% trichlorfon crystals were blended into sweet and sour vinegar at a ratio of 1:3:6:9:1 and placed between sunflowers to trap and kill.

(3) Chemical control. In the exoskeleton of white star beetle adult, 50% phoxim EC 1 000 times, 25% quinoline EC 1 000 times, 30% trichlorfon EC 500 times, 48% chlorpyrifos EC 1500 times, 20% fenpropathrin cream 1500 times spray.
