The scientific name (Carposina niponensis Walsingham) is also known as the peach aphid moth, referred to as â€œPeach Some?â€, which belongs to the order Lepidoptera. It is referred to as Peach Small, and is aliased as Zao Tsui, Locust, Wormwood, etc. Widely distributed in our country. North of 31 degrees north latitude and 102 degrees east of the north of the fruit area of â€‹â€‹the north.Parasitic plants include apples, pears, flowers, red sea bream, hawthorn, peach, plum, apricot, dates, etc.. Larvae damage the fruit. All occurred, the northern jujube area occurred more serious, is jujube, apple, peach, apricot, hawthorn and other fruit tree major fruit pests, serious damage when the rate of pests up to 90%, there is no use value, causing serious economic losses.
Harmful? Fruit larvae burrow around the core, worms remain in the fruit, unbearable.

The egg is oval, with a pale red color and a dark red color.

??Life history and habits ??Northern jujube area 1 year 1 to 2 generations, Shanxi province jujube area 1 year 1 generation, Hebei jujube area is mostly 2 generations, mature larvae in the soil around the trunk winter, 4 ~ 7cm soil More distribution within the layer. Overwintering larvae Before the wheat harvest in June of the following year, the average daily temperature was about 20Â°C, and the soil moisture content was more than 10%. The unearthed period was constrained by rain conditions, and the rainy season was early unearthed early. After the rains appeared in June and July, the excavation peak appeared. Jujube garden is more harmful than dryland jujube garden. Adults do not have phototaxis and chemotaxis, but have strong divergence and can be tempted and killed by P. minor sex attractants. The larvae emerged on the ground after being unearthed, and they emerged after 10 days. The adults were protected from light, lurking during the day, nocturnal activities, copulation and spawning, and the eggs were prolific in the back of the leaves and fruit stems and pods. Each female gave birth. About 50 eggs, more than 200 tablets, egg period of about 7 days. The larvae crawled for several hours on the fruit surface after hatching and the fruit was harmed. One insect only harmed one fruit, and there was no risk of turning fruit. The larvae matured in about 18 days, and the fruits were detoxified for 1 to 2 days. The second-generation adults emerged in about 10 days, and the second-generation larvae in the oviposition hatchery again suffered fruit damage. In September, the larvae became mature and the tribal lands became mature. Overwintering in winter, some fruits are brought into the cool spot and the barn.
?? Prevention methods
1. Beginning in late July, picking up and down the tree every 3 to 4 days to remove the larvae in the tree.
â€¢ In May and May, the larvae were covered with mulch film around the trunk before unearthing, which inhibited the larvae from unearthing and had a conservation effect.
? 3, late autumn and early winter turn the tree plate, use winter frozen to death part of the overwintering larvae.
? 4, the use of small incentives to trap adult insects, starting from June, every 666.7m2 hang a trap.
? 5, chemical control: According to the sex sensor measurement, timely spraying. When the first male moth is found, the overwintering larvae emerged as a flourishing period and can be controlled on the ground. The canopy was sprayed with 200-fold solution of 50% phoximidine EC and sprayed gently. The moth trap peaks for about 17 days. It is the best time for spraying on the trees. Generally from mid-July to early August, it can spray 2.5% deltamethrin 3000 times solution or Peach Xiaoling 1000-1500 times solution. Application of 25% Diflubenzuron No. 3 suspension 1000 times liquid, in the hazard period of fruiting moths, spraying once every half month, timely control effect is good.
