Abstract

The invention provides an insect attractant and its preparation method and application. The insect attractant includes thujene, and the preparation method is as follows: preparing a solution of thujene with a concentration of 50v / v% to 57v / v% to obtain Insect attractants. The insect food attractant of the invention can simultaneously trap bemisia tabaci, aphids and thrips, reduce the incidence of vegetable virus diseases, be safe and pollution-free, and is a new technology for the prevention and control of vegetable virus diseases. The preparation method is simple and can be applied to trapping insects in the field, and has the advantages of high trapping efficiency, prevention and control of vegetable virus occurrence, and the like.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to an insect food attractant and a preparation method and application thereof. Background technique [0002] Vegetable virus disease is a kind of disease that harms very seriously in vegetable production, seriously affecting the quality and safety of vegetable production. Vegetable viral diseases are mostly transmitted by vector insects, such as Bemisia tabaci, aphids, thrips, etc. Conventional control measures mainly rely on chemical pesticides, but the abuse or indiscriminate use of pesticides in production leads to the development of pest resistance and pesticide residues in vegetable products Exceeding standards and environmental pollution. [0003] In the field, bemisia tabaci, aphids and thrips are mixed, but bemisia tabaci, aphids and thrips are three different vector insects, and there are significant differences in growth and development, feeding, etc., which are harm...
