Due to the characteristics of large reproduction quantity, short reproduction period, obvious generation overlapping, difficult prevention and control and the like, the silkworm mulberry field is easy to outbreak and cause disasters under proper conditions, and the continuous development of the silkworm mulberry industry is seriously influenced. At present, the traditional chemical prevention and control means is mainly used for preventing and controlling the pests in production, and the high prevention and control effect is obtained, and the defects of drug resistance of the pests, environmental pollution, pesticide residue, influence on safety of people and livestock, silkworm breeding poisoning and the like are also accompanied. Therefore, the research and development of a novel technology for efficiently preventing and treating the nuisanceless mulberry borers is urgently needed.
At present, the green prevention and control technology of important pests of mulberries (such as mulberry borer, mulberry caterpillars, mulberry loopers and the like) mainly focuses on related researches on sex pheromone attractants, and corresponding sex attractant products are also obtained, however, trapping objects of insect sex pheromone attractants researched at home and abroad are male adults, and attractant products taking female moths as trapping targets are only reported, so that the researches and the applications of the attractants of female adults are lacked, and further the comprehensive sustainable prevention and control of the pests are influenced. The direct factor of outbreak of the mulberry borers lies in that the female moths lay eggs to generate next-generation pests, and in order to reduce the occurrence base number of the next-generation pests, attention needs to be paid to trapping and killing the mulberry borers before and after mating, so that the aims of preventing and reducing harm are achieved.
Related researches find that the insect has an intricate olfaction system, different volatile small-molecule odor substances in the environment can be detected and identified, and the phytophagous adults usually search suitable plants according to plant volatile matters to finish the processes of feeding, mate seeking, mating, oviposition and the like. In production and field investigations we found: the female moths of the mulberry borers have better flight capability, and the eggs laid by the female moths have the selection habit of the tender tips of the mulberry trees, so the host selectivity is bound to be related to volatile substances of the tender tips of the mulberry trees, and if the plant protection function of effective active substances contained in the plant volatile substances is developed and researched, the method has great practical significance and application in the technical field of green plant protection.
Therefore, through long-term tests and researches, the volatile components of n-hexacosane, trans-3-hexen-1-ol and n-butyl acrylate at the young tips of the mulberry trees are screened out to have the possibility of attracting the egg laying of the female moths of the mulberry borers, so that the research on the attraction effect of the 3 active components on the egg laying of the female moths of the mulberry borers lays a foundation for developing the egg laying attractant of the female moths of the mulberry borers and provides a new control technology and a product for green control of the mulberry borers.
Therefore, how to provide the muller moth attractant, and the preparation method and the application thereof are problems to be solved urgently in the field.
