The rejuvenation method of umbrella skirt chasing fly

Abstract

The invention discloses an exorista civilis rondani rejuvenation method. The exorista civilis rondani rejuvenation method includes the step that generation-breeding exorista civilis rondani is fed with a cane sugar aqueous solution of 20% to be rejuvenated. The egg laying amount, the emergence amount, the female life and the pupal weight of the generation-breeding exorista civilis rondani fed with the cane sugar aqueous solution with the mass percentage concentration of 20% are remarkably superior to the egg laying amount, the emergence amount, the female life and the pupal weight of the generation-breeding exorista civilis rondani fed with other nutrient solutions. The exorista civilis rondani rejuvenation method is researched and developed on the basis that the generation-breeding degradation law of exorista civilis rondani is clear, the effect of preventing exorista civilis rondani can be improved, and preventing cost can be reduced.

Description

technical field [0001] The invention relates to a method for rejuvenating umbrella skirt chasing flies in the field of proliferation of umbrella skirt chasing flies. Background technique [0002] Exorista civilis Rondani., Diptera: Tachinidae, is a multi-master parasitic natural enemy insect and the dominant parasitic natural enemy of meadow moth, which plays an important role in controlling the population density of meadow moth. effect. A survey in Kangbao, Hebei Province found that its eclosion rate accounted for 31.04% of parasite eclosion rate. At present, scholars have conducted a lot of research on the biological characteristics, parasitism, alternative hosts and host functional responses of the parasitoid fly, and some research results have been obtained. The parasitism rate of the shed flyer decreased with the increase of the density of the host (meadow moth). When the ratio of the shed flyer to the meadow borer reached 2:20, the parasitism rate and eclosion rate r...

Problems solved by technology

[0003] Although the large-scale expansion of parasitoids under indoor conditions can solve the problem of large-scale production, the control effect will decrease with the increase of generations, and the cost of control will increase with the increase of generations

Dai Pingli et al. found that the parasitism rate of Scleroderma guanii was greatly reduced by long-term use of Scleroderma chrysalis to proliferate, and the parasitizing Scleroderma guanii also showed low egg production by female bees, high larval mortality, and long-term developmental period. As a result, the number of progeny bees produced by each female bee continues to decrease, and the vitality decreases

Hu Xia et al. have used Tenebrio molitor to multiply Scleroderma sichuanensis for a long time and found that the ability to search for parasitism has obviously degraded. The average search rate of sichuan wasp bred by Tenebrio molitor is 30%, and the parasitism rate is 24.4%. The average search rate and parasitism rate of Scleroderma scleroderma to Beetleus sclerophylla was 39.33% and 37.33%

At present, there are few studies on the rejuvenation technology of insects after degradation, mainly focusing on the research on the resource insect bees, and there are also a few reports on the rejuvenation of fruit flies
