Problems solved by technology

Natural honey is rich in sugar and vitamins, which can basically meet the nutritional needs of Bactrocera dorsalis adults, but the disadvantage is that the adult mortality rate is high, and the egg production and egg hatching rate are relatively low
It has been reported in the literature that the use of peptone, yeast and sucrose as the main nutritional components to form artificial feed can increase egg production, but the hatching rate of eggs is not stable, and the feed needs to add many ingredients, and the process is complicated
Moreover, the existing Bactrocera dorsalis larvae feeding formula has the problem that some components such as wheat germ are difficult to purchase, and the practicability is not high. The improved larval feed formula also generally has the problems of moldy feed, low larval survival rate and stunted growth. question

Embodiment 1

[0014] Embodiment 1 large-scale breeding of Bactrocera dorsalis

[0015] 1. Adult artificial diet screening

[0016] 30 pairs of newly emerged female and male adults per cage provide 4 different feeds respectively. Feed A is yeast: sucrose=1:3; Feed B is yeast extract: sucrose=1:5; Feed C is yeast extract: sucrose= 1:8 (both mass ratio); D feed is the adult feed formula of Yuan Shengyong (2006). On the 7th day after adult eclosion, eggs were collected, put into the ovum collection tube at 9:00 every day, and taken out at 17:00, and recorded the number of eggs laid and the number of dead adults every day. The hatching rate of eggs was randomly selected 100 eggs, and the number of hatched larvae was observed, and the hatching rate of larvae and the mortality rate of adults were counted.

Abstract

The invention relates to the field of plant protection, and specifically relates to a bactrocera dorsalis large-scale feeding method. The method comprises the following steps: adults are fed, wherein a modified artificial feed comprises yeast paste and sucrose with a mass ratio of 1:8; eggs are collected; larva are fed, wherein the larva are fed by using an artificial feed in which a mass ratio of corn flour to yeast powder is 19:7; and pupa are managed. The method has the advantages of high egg production amount, high egg hatching rate, high pupation rate and high eclosion rate.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to a large-scale breeding method for Bactrocera dorsalis. Background technique [0002] Bactrocera dorsalis (Hendel), also known as Oriental fruit fly, yellow fly, fruit maggot, belongs to Diptera, Tephritidae Tephritidae, Bactrocera, mainly distributed in Southeast Asia and some islands in the Pacific Ocean ( Waterhouse, 1993, 1997). The host of Bactrocera dorsalis reaches more than 250 kinds, especially guava, mango, peach, carambola, jujube and other fruit varieties suffer the most (Liang Guangqin et al., 2008). In view of the wide host range of the insect, rapid reproduction and serious harm to the fruit trade, many countries list it as a quarantine object. The use of environmentally friendly control methods to control pests is the current trend of pest control. The realization of large-scale breeding of Bactrocera dorsalis is conducive to the development of environmentally fr...
