Method for controlling fruit fly pupae through combination of spalangia endius and insecticide

Abstract

The invention provides a method for controlling fruit fly pupae through combination of spalangia endius and insecticide. The method finds that when the abamectin is combined with spalangia endius, the abamectin has a good control effect on pupae of tephritidae such as bactrocera dorsalis, bactrocera cucurbitae and bactrocera cucurbitae. The method is simple and convenient to operate and facilitates industrial popularization and application.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a method for jointly controlling fruit fly pupae with insecticides. Background technique [0002] Bactrocera dorsalis Hendel, Bactrocera dorsalis Zeugodacus cucurbitae (Coquillett), and Bactrocera cucurbita Z. tau (Coquillett) are important worldwide quarantine pests that damage fruits and vegetables, and are also the three most dominant species of fruit flies in southern my country. The damage of the three types of fruit flies to fruits and vegetables is basically destructive. The female adults lay their eggs in the fruit, and after hatching, the larvae drill and eat in the country, which often leads to fruit deformity, rot, unripe yellowing, and fruit drop, which seriously affects The quality and quality of the fruit. The three species of fruit flies have a wide range of hosts, which can damage more than 250 species, more than 120 species, and more than 80 kinds of ...

The damage of the three types of fruit flies to fruits and vegetables is basically destructive. The female adults lay their eggs in the fruit. After hatching, the larvae drill and eat in the country, often resulting in fruit deformity, rot, unripe yellowing, and fruit drop, which seriously affects Fruit quality and quality

The three species of fruit flies have a wide range of hosts, which can damage more than 250 species, more than 120 species, and more than 80 species of fruits and vegetables; their reproductive ability is extremely strong, and a female adult can produce hundreds of thousands of eggs in a lifetime, and several generations a year , causing serious economic losses to my country's agricultural production

The killing of pupae mainly depends on the release of pupae parasitoids. At present, the pupae parasitoid that pays more attention is Spalangia endius Walker. Low, research reports have found that the lethal rate of the chrysalis wasp to the fruit fly pupae in the field is as high as 33% (Field evaluation of Spalangia endius Walker in controlling Zeugodacus cucurbitae (Coquillett), International Journal of PestManagement, 2021, 67 (3) :216-221)
