A kind of method for artificially propagating fly chrysalis helper wasp

Abstract

The invention discloses a method for artificially breeding Spalangia endius Walkers. A cage rearing method is used for rearing adult houseflies, wheat bran, the water content of which is 65 percent, is used as egg-laying substrateto lure the houseflies to lay eggs, the housefly eggs on the egg-laying substrate are collected and reared, so that older larvae are obtained, and the older larvae are collected and pupated, so that housefly pupae are obtained; female Spalangia endius Walkers are introduced into a breeding cage, the housefly pupae are put into a screen according to the number proportion of 1:10 and then placed into the rearing cage, and the housefly pupae on which the female Spalangia endius Walkers parasitize are collected; the obtained parasitized housefly pupae are put into a beekeeping cage, Spalangia endius Walkers are driven into a collecting cage from the surfaces of the housefly pupae after the eclosion of the Spalangia endius Walkers, and thereby the Spalangia endius Walkers are obtained. The method has the advantages that as the cage rearing method is adopted to rear adult houseflies, breed the Spalangia endius Walkers and collect the Spalangia endius Walkers, the escape of the parasitic bees and the housefly hosts can be effectively prevented, the artificial breeding of the Spalangia endius Walkers is conveniently realized, the injury of the Spalangia endius Walkers is minor, and the breeding efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of chrysalis bee breeding, in particular to a method for artificially propagating chrysalis bees. Background technique [0002] Fly pests are important pests in the production of many kinds of melon and fruit agricultural products such as bayberry, cherry, citrus, and bitter melon. The fruit that has entered the mature stage becomes soft and has a strong fragrance, which lures female flies to lay eggs on the fruit. After hatching, the larvae Moth damages the fruit, the fruit shape of the affected fruit is poor, the juice overflows, and the fruit is easy to drop, resulting in poor quality and reduced yield, which seriously affects fresh sales, storage and processing. [0003] The method of using parasitoid wasps to carry out biological control on target pests is a green and pollution-free pest control method. The reproduction of parasitic wasps depends on the specific insect state of the target pest, and wil...
