Embodiment Construction

[0032] The following is further described in detail through specific implementation methods:

[0033] The reference signs in the drawings of the description include: one-way light trapping bottle 1, hanging ring 2, trapping port 3, light strip 4, lamp bead 5, transfer tube 6, collection bottle 7, release paper 8, curtain 9 .

[0034] Heterochromia rearing test is divided into two treatment groups, is respectively two stages feeding treatment group (adopting feeding method of the present invention) and traditional feeding treatment group (adopting traditional soybean feeding method), and each processing group is provided with 3 repetitions , each replicated 8 pairs of Heterochromia, the ratio of male to female was 1:1. The feeding environment conditions of the two treatment groups were as follows: ambient temperature 28° C., relative humidity 75%, and light L:D=8:16.

[0035] Such as figure 1 Shown, the method that two stages of feeding treatment group raises Heterochromia c...

Abstract

The invention relates to the field of insect raising and particularly discloses a light, simple and efficient two-stage harmonia axyridis raising method. The light, simple and efficient two-stage harmonia axyridis raising method comprises the following steps: S1, aphid introduction onto tobacco, wherein aphids are introduced onto tobacco leaves, and then the tobacco leaves with introduced aphids are put in a net room for raising; S2, expanding propagation of tobacco aphids, wherein harmonia axyridis egg blocks are inoculated when the population density of the aphids on the tobacco leaves is greater than 20,000 on each plant; S3, raising of harmonia axyridis larvae, wherein aphids are regularly supplemented before harmonia axyridis pupates; S4, raising of adult harmonia axyridis, wherein anew batch of harmonia axyridis egg blocks are put after all harmonia axyridis pupates, the adult harmonia axyridis is trapped with a one-way light trapping bottle at night after all harmonia axyridisemerges, and the trapped adults are transferred and raised. By adopting the method, the problems of high harmonia axyridis raising cost, smaller individuals of harmonia axyridis and small egg laying amount due to frequent replacement of host plants in the existing ladybird raising process.

Description

technical field [0001] The invention relates to the field of insect breeding, in particular to a light, simple and efficient two-stage feeding method for the heterochromia ladybug. Background technique [0002] Biological control is one of the main technologies for the green prevention and control of agricultural and forestry pests, and natural enemy insects are the basis of biological control, so the importance of natural enemy insects is self-evident, and large-scale breeding of natural enemy insects is the core technology of biological control. Heterochromia is one of the main predatory natural enemies of crop pest aphids. Both adults and larvae of Heterochromia feed on aphids, and the amount of aphids caught in a lifetime is more than 6,000. The color ladybug is the basis for aphid control. [0003] The traditional Heterochromia breeding technology mainly adopts the three-level breeding technology system of soybean-aphids-ladybug. Because the growth period of soybean is...
