Attractant composition for preventing and treating mythimna lorgi and application of attractant composition

Abstract

The invention discloses an attractant composition for preventing and treating mythimna lorgi and application of the attractant composition. The attractant composition disclosed by the invention comprises a mythimna lorgi sex pheromone and a plant volatile matter component. The mythimna lorgi sex pheromone comprises cis-9-tetradecene acetate and cis-7-dodecene acetate. The plant volatile matter is one or more of 6-methyl-5-heptene-2-ketone, 1-octene-3-alcohol and phenethyl acetate. The ratio of the mythimna lorgi sex pheromone to the plant volatile matter is 1: (0.05-0.2). The attractant composition disclosed by the invention has relatively strong trapping capability on mythimna lorgi, is environment-friendly and nontoxic and harmless to a human body, and the raw materials are low in cost and easy to obtain. The attractant composition disclosed by the invention can be accurately applied to insect condition forecasting and mass trapping, and has important significance on comprehensive prevention and control of mythimna lorgi.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to an attractant composition and application for preventing and controlling Armyworm rouleyi. Background technique [0002] Leucania loreyi (Duponchel) belongs to Lepidoptera (Lepidoptera) Noctuidae, mainly distributed in my country's Guangdong, Gansu, Fujian, Sichuan, Jiangxi, Hunan, Hubei, Zhejiang, Jiangsu, Shandong, Henan, Hebei and other places. The feeding habits of the larvae are very miscellaneous, and they mainly harm grass crops such as rice, corn, sorghum, and wheat. They feed on corn and wheat and develop rapidly. Currently, they are one of the important pests on corn. Studies have shown that the occurrence of Armyworm lauii is slightly different in different geographical locations. In Guangdong, 6-7 generations can occur a year. 4 generations, but this worm cannot overwinter in Henan and Hebei. The fundamental reason affecting the growth and deve...

Problems solved by technology

However, with the emergence of pest resistance, the control effect will be significantly reduced. At the same time, the application of chemical pesticides will also affect the survival of natural enemies, cause a series of problems such as ecological environment damage and food quality and safety, which has become an important obstacle to the sustainable development of agriculture.
