Description
Technical Field
The invention belongs to the field of pest control, and particularly relates to an apple-daphne genkwa plant source attractant active component and an attractant.
Background
The insect of Melaninae family of Coleoptera of Malaysia is black, slender, erect and long-hairy with black, hard with yellow black spot, 1 pair of black round spots at 1/4 of the base, and 2 spots at the middle and end, and is chewing mouthpart as leaf eating pest. The length of the adult is 11-23 mm, the width is 3.6-7 mm, and the adult can fly and jump well. Oval, milky white, laid in soil and manure, yellow-brown head, milky white breast and abdomen. The main distribution is black dragon river, jilin (Qiaogo), liaoning, inner Mongolia, hebei, beijing, shandong, shanxi, henan, shaanxi, ningxia, gansu, qinghai, xinjiang, hubei, jiangsu, zhejiang and so on, and the distribution is also in Xian peninsula, russia, mongolia, middle Asia, europe, dongfei and North Fei. The feeding habits are wide, adults eat pests on melons, fruit trees, beans, vegetables, wild peony, motherwort, astragalus, caragana, platycodon grandiflorum and other crops, larvae live in soil and mainly feed on locust eggs. In an orchard, larvae mainly damage fruit trees and plant roots, adults eat a large amount of young tree leaves and young shoots, damaged leaves are in a net shape, and the serious young tree leaves and the young shoots are eaten, so that plants die. The hosts are relatively wide, adults hide in the crop, weeds beside ridges and soil on the ground surface in the newly-built orchard in the daytime, and a large number of adults are gathered to be harmful in the morning and evening and after rain, have pseudodeath and phototaxis and have certain tropism to sugar-vinegar liquid. Spawning in soil and farmyard manure in the last 9 th month, and the propagation coefficient is large.
Abnormal climates can cause the insect to spread in large numbers. In the orchard using a large amount of non-decomposed farmyard manure in the initial stage of orchard establishment, the damage rate of plants reaches 45% -73%, the damage rate of the orchard using the decomposed farmyard manure is 18.9%, and the damage rate of the orchard not applying the farmyard manure is 8.1%. The damage rate of young trees with fine cultivation management and strong tree vigor is 11.3 percent, and the damage rate of young trees with weak tree vigor after being placed for growth is as high as 54 percent. At present, the prevention and treatment measures of the apple daphne genkwa mainly comprise agricultural prevention and treatment, biological prevention and treatment, physical prevention and treatment and chemical prevention and treatment methods, wherein the agricultural prevention and treatment comprises scientific fertilization and reasonable intercropping; the biological control comprises the steps of protecting natural enemies, trapping adults by using sex attractants, trapping pests by using a sweet and sour liquid bottle, and spraying metarhizium anisopliae to soil or animal manure; the physical prevention and control comprises light trapping and killing and manual catching. The existing prevention and control measures consume a large amount of manpower and material resources, chemical prevention and control can pollute the environment, kill natural enemies, harm human health and increase the drug resistance of pests, so that the prevention and control are increasingly difficult. Therefore, from the viewpoint of ecological environment and food safety, finding stable and efficient green prevention and control technologies has become the key work of modern pest control.
At home and abroad, few research reports are carried out on the attractant of the genkwaninidae of coleoptera, the cantharidin (terpenoid substance) secreted by the genkwanin imagoes is a very effective intraspecific and interspecific pheromone, the content of the sexually mature male imago cantharidin can reach 10 percent at most, and the female genkwanin selects males with high gonadal cantharidin content to mate, so that the application of the cantharidin to the information chemical substance is proved. In addition to the attraction to the heterogeneous individual, cantharidin is also a chemical information substance for natural enemies of lilac daphne and various insects. In the last 50 years, stork firstly realizes the full chemical synthesis of cantharidin in a laboratory, furan and 1, 4-dicarboxylic acid dimethyl ester-2-butyne are used as raw materials, but the reaction conditions are severe and difficult to be used for actual production. The synthesis of cantharidin by Diels-Alder reaction with furan and dimethylmaleic anhydride malonic acid by post scientists has not been carried out in large quantities to date. There is still no debate as to the biosynthetic pathway of cantharidin and its distribution within the insect body, despite some studies.
Through the search of relevant patent documents, for example, patent CN202122092793, (orchard green manure yuankanin trapping device) provides an orchard green manure yuankanin trapping device, which traps and kills yuankanin by trapping liquid in a trap body, thereby realizing the trapping of the yuankanin. No relevant literature or report about the apple-spotted coriander plant-derived attractant is found unless the apple-spotted coriander plant-derived attractant is found.
