Method for collecting aged larvae, pupae and adults of bactrocera dorsalis

Abstract

The invention discloses a method for collecting aged larvae, pupae and adults of bactrocera dorsalis. Aged-larva-containing feedstuff is poured into an uncovered mesh box, the uncovered mesh box is suspended, then, a white plastic case is placed under the uncovered mesh box, and the aged larvae are transferred into the white plastic case by using a bouncing habit of the aged larvae so as to collect the larvae. The aged-larva-containing feedstuff is poured into the uncovered mesh box, then, the uncovered mesh box is placed into the white plastic case laid with sterilized sandy soil, the aged larvae are transferred into the sterilized sandy soil for pupation through bouncing, and then, the pupa-containing sterilized sandy soil is poured into another mesh box so as to screen out pupae. A bottle body and bottle bottom of a spring water bottle is provided with small holes, methyleugenol infiltrated sterilized degreased cotton is arranged in the bottle, then, the spring water bottle is suspended in an insect culture cage, and males are trapped into a trapping bottle through methyleugenol. A bottle cap of a glass bottle is provided with two glass tubes: one end of one glass tube is provided with gauze, and the other end of one glass tube is connected with a dust collector through a long plastic tube; one end of the other glass tube is open, and the other end of the other glass tube isconnected with a glass suction tube through a long plastic tube; and females are collected into the glass bottle through a suction force of the dust collector.

Description

technical field [0001] The invention relates to a method for collecting mature larvae, pupae and adults of Bactrocera dorsalis, in particular to a method for collecting larvae, pupae and adults in the breeding process of Bactrocera dorsalis, and belongs to the field of agricultural science and technology. Background technique [0002] Bactrocera dorsalis Hendel belongs to the genus Bactrocera of Diptera Tephritidae. Its larvae feed on the fruit and cause damage. It often causes the fruit to yellow and fall off before it is ripe. It is a second-class quarantine pest in my country. The insect can harm more than 250 kinds of fruits (mango, guava, custard apple, apple, carambola, loquat, etc.) and vegetables (eggplant, cucumber, tomato, etc.). Fruits harmed by Bactrocera dorsalis larvae have a huge impact on their quality and yield, and areas where severe occurrence can reduce more than 80% of the yield, or even fail to harvest. [0003] Bactrocera dorsalis is a serious hazard ...

AI Technical Summary

Problems solved by technology

In the past, the method of collecting larvae in the process of raising Bactrocera dorsalis was to manually pick out the larvae from the feed with tweezers, and to collect the pupae was also to use tweezers to pick out the pupae from the sand. The above methods are time-consuming and labor-intensive, and Bactrocera dorsalis are vulnerable to mechanical damage during operation.
