Embodiment Construction

[0026] The following embodiments further describe the present invention in conjunction with the accompanying drawings.

[0027] The specific implementation steps of the indoor propagation technology of the crocodile beetle of the present invention are as follows:

[0028] 1. See figure 1 , place a single 4-5 instar larvae in a finger-shaped glass tube, use a fluke tube to connect to a 1:1-2:1 male-to-female ratio of B. Seal the mouth of the glass tube with gauze, put the absorbent cotton ball dipped in the nutrient solution, and wrap the finger-shaped glass tube with black cloth to let the parasitic wasps parasitize the larvae of the large borer for 6-8 hours.

[0029] 2. After 6-8 hours of parasitism, take out the larvae from the finger-shaped glass tube, and then insert the non-parasitic larvae into the finger-shaped glass tube of B. To the complete death of B.

[0030] 3. During the parasitic process of P. japonica, if part of P. chinensis in a single finger-shaped glas...

Abstract

The invention relates to an indoor propagation method of Cotesia flavipes Cameron. The method comprises the following steps of firstly putting single-head 4-5-year-old Sesamia inferens larvae into finger-shaped glass tubes, inoculating the Cotesia flavipes Cameron with the female-male ratio of 1:1 to 2:1, sealing glass tube openings with 100-200-mesh fine mesh gauze, putting absorbent cotton ballsdipped with a nutrient solution on the 100-200-mesh fine mesh gauze, and wrapping the finger-shaped glass tubes with black cloth, so that the Cotesia flavipes Cameron parasitizes the Sesamia inferenslarvae; then taking out the Sesamia inferens larvae parasitized for 6-8 hours from the finger-shaped glass tubes, and inoculating the unparasitized Sesamia inferens larvae into the finger-shaped glass tubes with the Cotesia flavipes Cameron; in the parasitic process of the Cotesia flavipes Cameron, if part of the Cotesia flavipes Cameron in the single finger-shaped glass tube dies, combining theCotesia flavipes Cameron in different finger-shaped glass tubes; and finally, taking out the parasitized Sesamia inferens larvae and putting the parasitized Sesamia inferens larvae into a feeding bottle for feeding until the Cotesia flavipes Cameron is engaged out from the bodies of the parasitized Sesamia inferens larvae. According to the method, the Sesamia inferens can be effectively bred in aparasitic mode, and expanding propagation of the population number of the Cotesia flavipes Cameron is facilitated.

Description

technical field [0001] The invention relates to an indoor propagation method of the scutellaria chinensis, which belongs to the research field of biological control of plant protection pests. Background technique [0002] Large borer Sesamiainferens (Walker) belongs to Lepidoptera (Lepidoptera), Noctuidae (Noctuoidae), stem moth genus ( Sesamia ), is an important borer pest of rice. The large borer was originally a secondary pest on rice, and domestic attention to it is much lower than that of the rice stem borer and the rice stem borer. However, in recent years, with global warming and changes in rice cultivation and planting systems, especially the widespread promotion of hybrid rice, the population of the large borer in rice fields has gradually increased, and damage has occurred year by year along the river, coastal areas, and parts of northern Jiangsu. Intensified, the occurrence of damage in southern Jiangsu has even surpassed that of Chilo borer, rising from a sec...
