Problems solved by technology
Because the green Lygus has piercing-sucking mouthparts and directly sucks the juice of plants, while the individual of the green Lygus is relatively small, and a single body, especially a young nymph, sucks less plant juice, unlike insects with chewing mouthparts It is easy to measure the size of food intake, so the determination of the food intake of different stages of the green ligus has become a bottleneck to determine the correct control period of the green ligus

Embodiment
[0020] In the embodiment of the present invention, the food intake of different worm states and the law of body weight growth of Lygus lygus in the embodiments of the present invention are collected from Zhanhua Dongzao Garden in Binzhou City, Shandong Province, and the ovum of Lygus lygus collected is placed on branches. After soaking in water for 5 hours, take it out and put it in the insect raising box to dry, then place the insect raising box in an artificial climate box (temperature: 25±1°C; photoperiod: L:D=16:8) to hatch, They were reared indoors with kidney bean pods to provide a source of insects.

The invention relates to a different green plant bug state feeding amount and weight gain rule measuring method, and the green plant bug feeding amount and the weight gain rule are researched. The research on insect trophic behaviors and feeding amounts is a prerequisite basis of discussing the insect hazard extent, prevention and control suitable time, and prevention and control indexes. In order to facilitate a field worker to adopt different prevention and control strategies according to different development phases of green plant bugs, the invention proposes applying a kidney bean weight loss method, the feeding amounts of a plurality of green plant bugs of the same age in days are measured simultaneously, the feeding amount of a single green plant bug is calculated, different state feeding amounts and the weight gain rule are researched, the overeating period of the green plant bugs is determined, and a basis is provided for the field worker to determine the prevention and control suitable time of the green plant bugs.
Description
technical field [0001] The invention relates to a method for measuring food intake and body weight growth of Lygus green bugs in different stages, and belongs to the technical field of agricultural pest control. Background technique [0002] The green Lygus is an important agricultural pest that seriously harms cotton, fruit trees and other crops in recent years. Lygus nymphs and adults can both pierce and suck, and mainly damage young vegetative organs such as buds, young shoots, and young leaves of plants and reproductive organs such as inflorescences, flower buds, flower buds, and young fruits. Symptoms of damage vary with host species and hosts The main manifestations are the formation of holes in plant buds, young shoots, and tenders, or the deformity and shedding of reproductive organs, which endanger the leaves, commonly known as "broken leaf madness", and seriously affect photosynthesis. [0003] However, in the nymph stage, the life of the green Lygus is very hidde...
