The scientific name Mimastra cyanura Hope belongs to the order Coleoptera. Alias ​​yellow leaf, yellow leaf A. Distribution of Jiangsu, Zhejiang, Fujian, Jiangxi, Guangdong, Sichuan, Guizhou, Hunan and so on. Host mulberry, ramie, marijuana, eucalyptus, indus and so on. The characteristics of the insects were as follows: the juveniles ate their leaves, and Yu Xi just opened the young leaves. The light leaves the leaves into nicks or holes, and the entire young leaves of the mulberry branches were eaten away, leaving only the main veins. Disposal of feces pollutes the lower leaves and seriously affects the yield and quality of spring mulberry leaves. Larvae feed on bryophytes, leaves, and weeds. Life habits are born 1 year old, and the mature larvae live in the soil for winter. In Jiangsu and Zhejiang, larvae were cleared in early April, feathered in mid-May, spawned in early June, hatched in mid-July, and gradually entered winter in early October. In late February, Sichuan will turn Huayu, and it will emerge in late March and mid-April. In mid-March, the damage occurred on the branches of eucalyptus, eucalyptus, indus, and samoic, and then they moved to the mulberry trees. When mulberry trees grew 8-9 leaves, the damage was the worst. The eggs began to be laid in May and hatched in early June. After November, soil was overwinter. The adult has a pseudo-dead and colony, flying strong, spread by the wind. However, when the morning, evening, and morning exposures were still dry, the flying force was weak. Usually only 1-2m flew when disturbed. Some wings spread away and they like to mate at 9am. Each female can undergo multiple matings of 1 hour each and spawning period of 30 days. 5-15 days after spawning, females die. The egg is prolific in the cracks on the soil surface or in the soil, and 171 eggs per female egg are hatched after more than a month. Many larvae are active on the surface of the soil, eating weeds or green leaves. After the end of October, earth-moving chambers were built 2-3cm. The larvae lived in the soil in the winter, and the larvae disappeared from February to March in the following year. The pupa period was 25-28 days. From March to April, it was unearthed after 2 days of emergence, and it was crawled on the grass just after being unearthed, and then flew to the tree. In the spring of the year, the occurrence of this worm was early and numerous, and the hilly land was more than plain water. Natural enemies have tea wing lice, adult nymphs suck yellow fluid body fluid to death. Prevention methods (1) Use the adult's pseudo-dead nature and intensive damage habits to dry the low-medium mulberry tree, vibrate the mulberry branch in the morning before the dew has dried, and let the leaf armor fall into the prepared wash basin with soap or washing powder or Lime in the lime. (2) Leave a small amount of shoots during summer harvesting. Do not cut mulberry leaves or cut them to attract insects. (3) When the morning dew is not dry, spray 80% dichlorvos emulsifiable concentrate 1000 times or 90% crystal trichlorfon 1000 times, 40% dimethoate emulsifiable concentrate 1000 times. (4) In the middle of October, when the 3rd instar larvae concentrate on the moss for feeding, spray 50% phoxim EC or 50% killer pine EC 1000 to 2000 times, 25% ECS 1500 times, control effect 90 %the above.
