Embodiment 1

[0018] The artificial breeding of embodiment 1 mixed chamber braconid

[0019] The mulberry borer is used as the host indoors, and the mixed-chamber braconid is artificially bred. The ages of the mulberry borer used are 1, 2 and 3 ages, and the parasitic female bees are 3-day-old, 4-day-old, 5-day-old, 6-day-old and 7-day-old mixed-chamber female wasps. Use a round transparent plastic box as the parasitic box. There is a small hole with a diameter of 1.5cm on the side of the parasitic box, which is convenient for introducing parasitic wasps. After the parasitic wasps are introduced, plug them into this hole with a cotton plug. Before the parasitic start, insert 20 mulberry borer larvae into the parasitic box, and half an hour later, insert the parasitic wasp mother bee. The parasitism ends after 24h. The mulberry borer larvae and female bees were recovered separately. Mulberry borer larvae were reared individually in small plastic boxes and fed with fresh mulberry leaves ev...

Embodiment 2

[0022] The artificial breeding of embodiment 2 mixed chamber braconids

[0023] The mulberry borer is used as the host indoors, and the mixed-chamber braconid is artificially bred. The ages of the mulberry borer used are 1 age, 2 ages and 3 ages, and the parasitic female bee is the age of 6 days of mating, and the used round transparent plastic box of the parasitic place is the same as in Example 1. The density of mulberry borer larvae in each parasitic box was 10, 15, 20, 25 and 30 when parasitic was set. Before the start of parasitism, the 3rd instar mulberry borer larvae were inserted into the parasitic box according to different densities, and half an hour later, a single parasitoid mother wasp was inserted. The parasitism ends after 24h. The mulberry borer larvae and female bees were recovered separately. Mulberry borer larvae were reared individually in small plastic boxes and fed with fresh mulberry leaves every day. After the cocoons of the parasitic wasps are form...

Embodiment 3

[0026] The artificial breeding of embodiment 3 mixed chamber braconids

[0027] The mulberry borer is used as the host indoors, and the mixed-chamber braconid is artificially bred. The ages of the mulberry borer used are 1 age, 2 ages and 3 ages, and the host density is 20 heads / box, and the female honeybee that parasitizes is the age of 6 days of mating, and the circular transparent plastic box used in the parasitic place is the same as embodiment 1. When setting up parasitism, the number of parasitoid bees placed in each parasitic box was 1, 2, 3 and 4, respectively. Before the parasitism begins, the mulberry borer larvae are first connected to the parasitic box, and half an hour later, the parasitic wasp mother wasp is connected. The parasitism ends after 24h. The mulberry borer larvae and female bees were recovered separately. Mulberry borer larvae were reared individually in small plastic boxes and fed with fresh mulberry leaves every day. After the cocoons of the par...

Abstract

The invention relates to an artificial breeding method for dominant parasitic wasps of mulberry borers. The artificial breeding method comprises the following steps that aiming at the biological characteristics of the mixed-chamber cotesia, larvae of the mulberry borers are taken as hosts; and the age of the mulberry borer larvae suitable for parasitism of the mixed chamber cotesia, the day age of the parasitism female bees, the density of the mulberry borer larvae during parasitism, the density of the parasitism female bees, the parasitism duration, the cocoon harvesting time after parasitism and the concentration of honey water for feeding parasitic adult cotesia are determined, so that stable mixed chamber cotesia are obtained. When the artificial breeding method is used for breeding the mixed-chamber cotesia, the parasitic efficiency is high, the operation is simple and convenient, the cost is low, the indoor artificial breeding of the dominant parasitic wasps of the mulberry borers is realized, the large-scale production of parasitic wasp products for preventing and controlling the mulberry borers in the field is facilitated, and a solid foundation is laid for performing biological prevention and control work of the mulberry borers based on the parasitic wasps.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, and relates to an artificial breeding method for the dominant parasitic wasps of the mulberry borer and mixed chamber braconids. Background technique [0002] The mulberry borer Glyphodes pyloalis is one of the major destructive pests of mulberry trees. Harm occurred. Due to the short reproductive cycle and large reproductive capacity of mulberry borer, it can break out in a short period of time when the conditions are suitable, forming overlapping generations and causing serious damage. The number of generations of the mulberry borer varies in different regions due to climate reasons, and overwinters as mature larvae in tree trunk cracks and maggot holes. There are 3-4 generations per year in Shandong and Guizhou-Guizhou regions, 4-5 generations per year in the Yangtze River Delta and Sichuan Basin, and 10-11 generations per year in Lingnan region, and there is...
