Also known as peach aphid, peach aphid, omnivorous pests, are distributed throughout the country. The larvae harm various fruits or seeds of winter jujube, peach, plum, persimmon, chestnut, apple, pear, pomegranate and hawthorn. When the fruit is victimized, it is filled with insect feces and causes rot. When it is serious, it has a great impact on the yield and quality.
Peach oysters are miscellaneous, have a long period of occurrence, and are often transported in areas with multiple host species. Two generations took place in the north in the first year, three to four generations in the Huanghuai area, and four to five generations in the Yangtze basin. The 2nd and 3rd generation larvae in Shandong endangered the pomegranate, jujube, jujube and peach the most. The second generation endangered sunflower, corn and various fruits. The winter of mature larvae. In the north of China, the overwintering adult can be eclosed in May of one year. During the day, it can be quiet and dark in the dark. At night, it can lay eggs at the night with 8-10 o'clock. Eggs are mainly produced in flower buds, and 1-6 grains range from single grain production. Newly-incubated larvae tend to eat into the fruit from the inside of the locust or in the concealed part of the double fruit or pasture. Larvae have a major hazard feature. After the larvae are matured, they often have long, elliptic white silk knots in the fruit or fruit, and in the bark joints, and they phlegm in the pods.
Destroy overwintering larvae. Scrape bark and plug tree holes in early spring. Timely treatment of sunflower flower discs, corn, sorghum and other stubbles eliminates overwintering larvae and reduces the source of insects. Pick up the fallen fruit and remove the damaged fruit, concentrate the manure, and use the black light to seduce the adult.
During adult emergence and spawning, spray 50% phoxim 1000 times, or 50% dichlorvos emulsion 1200 times, or use pyrethroid pesticides. The first-generation larvae sprayed 50% of azao pine or 40% of dimethoate emulsion at the initial stage of incubation, and sprayed once a week later. The effect was good.
With 50% phoxim or 20% of pyrethroids or 90% of trichlorfon 0.5 kg plus soil 00 times and water 10 grams, and into the medicine mud, group clogging the carcass, not only the prevention of first generation larvae, but also Prevention of second and third generation larvae, valid for 70-80 days. The use of peach aphid spawning on the sunflower flower disk has a strong tropism, planting some sunflower in the orchard, after flowering to induce adult eggs, regularly spraying to eliminate.
