Problems solved by technology

In recent years, meadow moths have caused continuous outbreaks in northern my country. Domestic researchers have tried to use artificially synthesized E11-14:Ac to lure male moths, but the trapping effect is not ideal. The reason may be that the sex of female moths in different geographic populations of the same species There are differences in pheromones, which can lead to the failure of the application of this pheromone in our country

Embodiment 1

[0019] Embodiment 1, the application of ethyl myristate as a sex attractant to lure the male meadow moth

[0020] 1. Source of tested insects

[0021] In the winter of 2010, meadow moth pupae were collected from Beiguan Village, Kangbao County, Hebei Province, and brought back to the laboratory and placed in an artificial climate chamber (RXZ-268B, Ningbo Jiangnan Instrument Factory), with a set temperature of 22±1°C and a humidity of 70±5°C. %, photoperiod 16L:8D. After they hatch, they mate and lay eggs for artificial rearing. Larvae were packed in glass bottles (diameter 8cm, height 10m) at a density of 30 heads / bottle, sealed with nylon gauze, and fed with Chenopodium album; female and male adults were separated by transparent plastic covers (diameter 8cm, height 20m) Raise, seal with nylon gauze, and feed with 10% glucose water.

[0022] 2. Sample preparation

[0023] The mating behavior of the male and female adults of the meadow borer occurred between 4 and 8 hours ...

Abstract

The invention discloses an application of ethyl myristate as a sex attractant for luring loxostege sticticalis. Furthermore, the invention provides a sex attractant for luring loxostege sticticalis, wherein loxostege sticticalis is taken as an active component of the sex attractant. The sex attractant, combined with a gas chromatography-mass spectrometer (GC-MS), a gas chromatography-electroantennogram measuring system (GC-EAD) and series behavior tests, carries out a chemical identification for sex pheromones of loxostege sticticalis population in China, and implements a field luring test for male moths. Research results show that by taking the ethyl myristate as a sex attractant for luring the release of female moths of loxostege sticticalis, the female moths, in a dark period of the 3rd day after eclosion, are under a calling state, and sexual glands stretch out of tail ends of the abdomens to release sex pheromones so as to attract the male moths to mate. The research achievement will provide a theoretical basis for the application of sex pheromone in insects monitor, prevention and control of loxostege sticticalis in China, so as to effectively prevent disaster caused by loxostege sticticalis on the husbandry in Northern China.

Description

technical field [0001] The invention relates to the field of plant disease and insect pest control, in particular to the application of ethyl myristate as a sex attractant for attracting male meadow moths. Background technique [0002] Meadow borer (Loxostege sticticalis) is a migratory pest distributed worldwide, belonging to Lepidoptera, Pyralidae, Pyraustinae, Pyraustinae genus, alias sugar beet net moth , Yellow-green stripe borer, mainly distributed between 34° and 54° north latitude. Meadow borer larvae have a wide range of feeding habits, and can damage more than 80 kinds of crops and forages such as sugar beet, alfalfa, soybean, potato, flax, sunflower, etc.; and the larvae are gluttonous, and the young larvae eat mesophyll tissue, residual epidermis or leaf veins, After the 3rd age, the leaves can be eaten up, and the damage can be transferred to other plots after eating up a crop, which can cause devastating damage to crops in a short period of time. Dozens of cou...
