Problems solved by technology

However, this method is cumbersome to raise procedures, because the aphid is sensitive to high temperature and cannot be supplied to the whole growth cycle of the red-colored stinkbug, and the pest bait needs to be replaced.
And at present there is no large-scale breeding method specifically for the red-colored stinger bug, so establishing a large-scale breeding of the red-colored stinger bug is simple, and is conducive to shortening the growth and development period, improving the survival rate and adult fecundity method is quite necessary

Embodiment 1

[0042] Embodiment 1 A kind of method that utilizes Chicory supercystis large-scale rearing of red-coloured stinkbug

[0043] 1. Breeding of nymphs

[0044] (1) Place the egg mass of the red-colored stinkbug in an artificial climate box, and cultivate it for 4 days under the conditions of temperature 28°C, relative humidity 60%, and light time 16h / d, and the eggs can hatch into nymphs.

[0045] (2) Large-scale breeding of the 1 to 2 instar nymphs of the red-colored stink bug: the 120-order insect cages with a length of 60 cm, a width of 40 cm, and a height of 40 cm were put into the 120-order insect cages of the nymphs of the red-colored stink bug after 24 hours of hatching. 150 newly hatched nymphs of stink bugs were placed in insect cages. Pour the aphids in the plastic collection box into a double-layer plastic nylon screen with an upper layer of 20 mesh and a lower layer of 120 mesh (the size of the screen mesh is 19.5 cm in inner diameter, 20.5 cm in outer diameter, 5 cm ...

Embodiment 2

[0052] Compared with Example 1, in step (2), 1 to 2 ages of Chicory aphids and stinkbugs were raised at a quantity ratio of 2:1; in step (3), 80 stinkbugs were put in each pitcher cage, and bitter Aphids aphids and stinkbugs were reared at a ratio of 3:1.

Embodiment 3

[0070] Embodiment 3 compares the nymph developmental period, nymph survival rate, and adult fecundity of the nymphs raised in the schemes of Examples 1-2 and Comparative Examples 1-8.

[0071] Table 1 Effects of different feeding schemes on the developmental duration of the nymphs of the red-colored stinkbug

[0072]

[0073] Note: The data in the table are mean ± standard error, and different letters after the data in the same column indicate significant differences after comparison by t test (P<0.05).

[0074] As can be seen from the data in Table 1, the nymphs raised using the scheme of the present invention have better development and the shortest development period. And changing the feeding program will affect the developmental duration of the nymphs of the red-colored stinkbug and reduce their growth and development speed.

Abstract

The invention provides a method and application for raising the red-coloured stinkbug on a large scale by using Chicory supercystis. The present invention selects Chicory supercystic aphids to raise the red-colored stinkbug, which can be used for raising the whole growth cycle of the red-colored stinkbug, and does not need to replace different pest baits in each growth period, which not only greatly simplifies the breeding procedure, but also uses bitter Compared with other aphids, the growth and development period of the red-colored stinkbug raised by A. aphids was shorter, the survival rate was higher, and the adult fecundity was stronger.

Description

technical field [0001] The invention belongs to the technical field of breeding natural enemy insects, and in particular relates to a method and application of using Chicory aphids to raise large-scale red-coloured stinkbugs. Background technique [0002] Rhinocoris fuscipes (Fabricius) is a natural enemy insect of the stinkbug family with strong predation ability. It can not only prey on pests such as aphids, tobacco budworms and Spodoptera litura on tobacco, but also prey on cotton bollworms on cotton. Mulberry pests such as saddle weevil, teak borer, rice brown planthopper, rice stem borer and rice leaf roller have very broad application prospects. [0003] The Chinese invention patent with the publication number CN109644950A provides a large-scale breeding method of the red-colored stinkbug, which is to use aphids to feed the young nymphs of the stinkbug, and then use the larvae of Spodoptera litura to feed the old nymphs and adults of the stinkbug. However, this method...
