Problems solved by technology

[0004] The survey of citrus psyllids by visual inspection is labor-intensive, and it is impossible to conduct a comprehensive survey on citrus trees with high plant types; in addition, the visual inspection method is random, and it is difficult to accurately estimate the population of citrus psyllids when the density of citrus psyllids is low. Periods of low density are often critical periods for monitoring citrus psyllid occurrence

Abstract

The invention discloses a compound-type diaphorina citri trap with combination of a smell volatile matter and color, and a method, relating to the monitoring technique of diaphorina citri insect pests. The trap comprises an odor volatile matter (10), a capillary tube volatilizer (20), a yellow sticky plate (30) and a lifting rope (40), wherein the yellow sticky plate (30) is provided with the capillary tube volatilizer (20); the odor volatile matter (10) is arranged in the capillary tube volatilizer (20); the upper part of the yellow sticky plate (30) is provided with the lifting rope (40); and the odor volatile matter (10) is a mixed volatile matter of beta caryophyllene and terpinolene. The compound-type diaphorina citri trap with combination of the smell volatile matter and the color is low in manufacturing cost, convenient for use, strong in attractive force and convenient for counting, is suitable for monitoring an invasion condition of the diaphorina citri in a potential distribution area, and also can be used for population quantity monitoring in a diaphorina citri generating area.

Description

technical field [0001] The invention relates to a monitoring technology for citrus psyllid pests, in particular to a composite citrus psyllid trapping device and method combining odor volatiles and colors, which are suitable for trapping citrus psyllid adults and monitoring citrus psyllids in citrus orchards. The amount of occurrence and the distribution range of diffusion. Background technique [0002] The citrus psyllid is an important pest of citrus. Adults suck on old and young leaves; nymphs gather on citrus shoots, young leaves and new shoots to eat and damage, the young shoots and shoots of the damaged shoots dry and shrivel, and new leaves are deformed and twisted and easy to fall off; nymph excrement spreads on branches and leaves, which will affect photosynthesis Effect and cause soot disease. More importantly, the citrus psyllid is the only vehicle for field transmission of citrus greening. Citrus huanglongbing is a systemic disease, which cannot be cured after...
