Artificially synthesized lima bean pod borer sex pheromone

Abstract

The invention discloses an artificially synthesized lima bean pod borer sex pheromone, which is prepared from the following components in percentage by weight: 18 to 21 percent of cis-11-tetradecaneenol acetic ester (Z11-14AC), 6 to 8 percent of cris-9-tetradecaneenol acetic ester (Z9-14AC), 6 to 8 percent of tetradecaneenol acetic ester (14AC), and 63 to 70 percent of n-hexane. The artificially synthesized lima bean pod borer sex pheromone is suitable for controlling domestic lima bean pod borers and has vary strong trapping capacity; the quantity of lima bean pod borer moths lured by each luring core is about more than 50 per day; the stability is good; the average effective period is as long as 30 days; the trapping efficiency is universally as high as 90 percent; the efficiency for preventing perfect insects from copulating through the functions of trapping and killing and disorientation is 50 percent; and the artificially synthesized lima bean pod borer sex pheromone can be used for forecasting, trapping and killing male moths and interfering copulations so as to achieve the effect of comprehensively controlling the domestic lima bean pod borers.

Description

technical field [0001] The invention belongs to the bionic high-tech field, and relates to the technology of artificially synthesizing insect sex pheromone, in particular to the formula of artificially synthesized composition of sex pheromone of bean pod borer. Background technique [0002] In nature, after adult female insects are sexually mature, they will call to the opposite sex in courtship and release a substance called sex pheromone. The sex pheromone is released into the air and spreads with the airflow, stimulating the chemical sensory organs in the antennae of males, causing sexual impulses in males and luring males to fly to the release source, and mate with released female adults to reproduce. [0003] Based on the biological characteristics of insects, biologists have separated, analyzed and measured the components of insect sex pheromones, successfully synthesized some insect sex pheromones, and applied them in pest prediction, trapping and integrated control ...

AI Technical Summary

Problems solved by technology

[0004] However, at present, the sex pheromone application research of many insect sex pheromones is still only at the theoretical level, because the component functions of many insect sex pheromones are not particularly clear, and the differences in insect geographical flora make Foreign pod borer sex pheromone lures cannot attract moths in China and show no effect. The technology is still mature, so many limitations in application

[0005] The bean pod borer is a bean pest that is distributed worldwide. The insect is distributed in all parts of my country. East China, Central China, and South China are the most affected areas. After being bitten, the bean grains lose their edible value and seriously affect the yield.
