Abstract

The invention discloses a method for preparing a fall webworm sex pheromone slow-releasing agent. The method comprises the following steps of: using (9Z, 12Z, 15Z)-octadecatrienal, (3Z, 6Z, 9S, 10R)-9, 10-epoxy-3, 6-heneicosadiene and (3Z, 6Z, 19S, 10R)-9, 10-epoxy-1, 3, 6-heneicosatriene as active components of sex pheromone, adding a stabilizer and then adding to polybutadiene resin; stirring to be uniform and obtaining a mixed solution; adding isocyanate which is isometric to the mixed solution into the mixed solution, continuously stirring and obtaining a paste-type finished fall webworm sex pheromone slow-releasing agent. The fall webworm sex pheromone slow-releasing agent disclosed by the invention has the advantages of single and high-efficient attraction effect to fall webworms, low price, non-pollution, good stabilization, non-volatility and wide prospect of application.

Description

Technical field [0001] The invention belongs to the field of pesticides, and specifically relates to a preparation method of a sex pheromone sustained-release agent of Hyphantria cunea. Background technique [0002] American White Moth (Fall webworm in English), also known as "Autumn Curtain Caterpillar" and "Autumn Curtain Moth" in Chinese synonym, belongs to the Lepidoptera order and the family Lampyridae. As a worldwide quarantine pest, Hyphantria vulgaris is native to North America, widely distributed in the northern United States, southern Canada and Mexico, and has been introduced to Europe and Asia since the late 1940s. Since the American white moth was introduced to my country in 1979, it has gradually spread to Hebei, Tianjin, Shandong, Shaanxi and Beijing. It is an extremely harmful leaf-eating pest, which seriously threatens ecological security. Its hazard characteristics are: first, it can harm more than 300 kinds of plants, including forest trees, fruit trees, crops...
