Embodiment 1

[0025] like figure 1 Shown, the large-scale propagation method of a kind of melon fly larva parasitoid Brachycarpus freundii comprises the following steps:

[0026] 1) Collection of Bacteralis adults: Collect bitter melons infested by Bacteria melons in the wild, and continue to cultivate them in bitter gourd hosts until adults of Bacteria melons.

[0027] 2) Breeding of Bactrocera melons adults: the newly eclosioned adults of Bactrocera melons are transferred to the insect cage, wherein, the density of the fruit flies raised in the insect cages is 10,000 / cubic meter, provided in the insect cages Nutrition and water for adults, specifically, a mixture of beer yeast powder and young granulated sugar of equal mass ratio is provided in the insect cage for the adults to supplement nutrition, and a sponge soaked in clear water is used for the adults to replenish water, and the temperature in the insect cage is 26°C , the humidity is 65%, the temperature and humidity should not be ...

Embodiment 2

[0035] like figure 1 Shown, the large-scale propagation method of a kind of melon fly larva parasitoid Brachycarpus freundii comprises the following steps:

[0036] 1) Collection of Bacteralis adults: Collect loofahs infested by B. melons in the wild, and continue to cultivate them in Luffa hosts until they become adults of B. melons.

[0037] 2) Breeding of Bacteralis melon adults: the newly eclosioned adults of Bactrocera melons are transferred to the insect cage, wherein the density of the fruit flies raised in the insect cage is 11,000 / cubic meter, provided in the insect cage Nutrients and water for adults, specifically, a mixture of brewer’s yeast powder and granulated sugar of equal mass ratio is provided in the insect cage for the adults to supplement nutrition, and a sponge soaked in clear water is used for the adults to replenish water, and the temperature in the insect cage is 27°C , the humidity is 70%, the temperature and humidity should not be too high, too high or...

Abstract

The invention discloses a large-scale propagation method of the larval parasitic wasp Brachycarpa freundii, comprising the following steps: 1) collecting adults of the fruit fly, 2) feeding the adults of the fruit fly, and 3) raising the adults of the fruit fly Egg acquisition, 4) propagation of the larvae of the melon fly, 5) rearing of the Brachycarpa freundii, 6) parasitism of the Brachycarpa freundii: 7) collection of parasitic hosts, 8) cultivation of the Brachycarpa freundii. The process is simple and low in cost, can be operated indoors, can reproduce all year round, is easy to be popularized on a large scale, and effectively improves the parasitic ability of the Brachycarpus freundii.

Description

technical field [0001] The invention relates to the technical field of reproduction of parasitic wasps, in particular to a method for large-scale propagation of the parasitoid Brachycarpa freundii, the larvae of the melon fly. Background technique [0002] Melon fly Zeugodacus cucurbitae (Coquillett) is an important invasive pest in my country. It has invaded and spread to more than 10 provinces and regions in China, and has a tendency to spread further. Melon fly has a wide range of hosts and can cause damage to more than 120 kinds of vegetables and fruits. Its reproductive ability is strong, and a female adult can produce hundreds of thousands of eggs in a lifetime, and can produce 3 to 9 generations a year, causing serious economic losses to my country's agricultural production. According to incomplete statistics, the social and economic losses caused by the fruit fly are tens of billions of yuan every year. At present, the control of fruit fly in my country mainly reli...
