Problems solved by technology

However, no research group in China has carried out similar work so far. Due to the geographical differences in sex pheromones, there may be some differences in the composition of sex pheromones in my country. Therefore, we have carried out relevant research to obtain the sex pheromones of citrus leaf miner in my country. The best ratio of composition

Embodiment Construction

[0025] In the field, the citrus leafminer sex pheromone components cis 7 cis 11 trans 13-hexadecatrienal, cis 7 cis 11-hexadecadienal, cis 7-hexadecenal 1~ The mass ratio of 100:0~100:1~10 strongly attracts the male moths, and it is effective in the dose range of 40 micrograms to 1333 micrograms per lure core, but the total dose of 400 micrograms is the best for trapping. It is equipped with appropriate water basins and viscose traps to trap and kill the male moths of the citrus leaf miner, which solves the current prevention and forecasting of the citrus leaf miner sex lure pests.

[0026] Doses ranging from 40 micrograms to 1333 micrograms per lure were effective, but a total dose of 400 micrograms was optimal for trapping.

[0027] The lure can last about 45 days in the field ( figure 1 ).

[0028] Cis 7 cis 11 trans 13-hexadecatrienal, cis 7 cis 11-hexadecadienal and cis 7-hexadecenal are all products of Ningbo Newcom Biotechnology Co., Ltd.

[0029] Table 1. Attractive...

Abstract

The invention relates to a sex pheromone composition for luring citrus leaf miner and a luring core thereof, which is characterized by comprising cis-7, cis-11, trans-13-hexadecatrienoic aldehyde, cis-7,cis-11-hexadecadienoic aldehyde, cis-7-hexadecene aldehyde according to mass proportion of 1-100:0-100:1-10 to produce the sex pheromone luring core. Each luring core within the dosage range of 40 micrograms to 1333 micrograms is effective, the general dosage for optimum trapping is 400 micrograms, the luring core is capable of maintaining for 45 days in field. A proper basin and a glued trap for grouping and trapping male moths of the citrus leaf miner are cooperated for solving the prevention and prediction of sexual luring insects such as the citrus leaf miner.

Description

technical field [0001] The invention relates to a sex pheromone composition for attracting citrus leafminer moths, making of lure cores and related trapping methods. Background technique [0002] Citrus leafminer Phyllocnistis citrella Stainton belongs to Lepidoptera and Lepidoptera. It is the main pest of citrus, and it is distributed in citrus producing areas all over the country. The larvae sneak into the skin of young leaves and shoots to feed, and bore into irregular silver-white tunnels. Therefore, fruit farmers in some areas call it "ghost painting charm", which leads to deformed and curled leaves, and leaves are prone to fall in winter. Due to the serious impact on photosynthesis, it affects the growth and fruiting of young trees. The damaged curly leaves are often "refuges" and overwintering places for pests such as citrus spider mite and leaf tortrix, increasing the chance of infecting citrus canker. The citrus leaf miner is the most important pest on the new sh...
