The invention relates to the technical field of biology, in particular to an athetis dissimilis sex attractant and a preparation method and application thereof. The athetis dissimilis sex pheromone composition comprises an athetis dissimilis female sex pheromone component and a solvent. Wherein the female insect sex pheromone component is prepared from cis-7-hexadecenal, cis-9-tetradecenol and cis-11-tetradecenyl acetate. The sex attractant disclosed by the invention is used for insect condition prediction and forecast or athetis dissimilis trapping; the method has the advantages of simple operation, obvious effect, harmlessness to natural enemies, people, livestock and the environment, reduction of the use of chemical pesticides in athetis lepigone control, facilitation of the protectionof the ecological environment and the realization of the zero increase of the use amount of pesticides in pest control, and good ecological, social and economic benefits.
Description
Technical field [0001] The invention relates to the field of biotechnology, in particular to a sex attractant for Spodoptera exigua and its preparation method and application. Background technique [0002] Noctuidae Athetis dissimilis (Hampson) is an important lepidopteran pest that newly occurred in summer corn fields after the reform of crop farming methods in my country in recent years. Its host plants are extensive. In addition to corn, it can also damage crops such as wheat, soybeans, peanuts and sweet potatoes. . Since it was first discovered in Shandong Province in 2012, its damage range has expanded year by year, and it has been found in Henan, Shaanxi, Anhui and other places in my country. When damaging corn, the larvae of Spodoptera litura mainly hide in the field litter, volunteer wheat seedlings or weeds and feed on the base of the corn seedling stems. In severe cases, the corn seedlings and ridges need to be replanted. Compared with the maize pest, the two-spotted m...
