Problems solved by technology

However, at present, a complete technical system for this bee has not been formed at home and abroad, so this natural enemy has not been able to fully play its role in the biological control of blind stink bugs

Embodiment 1

[0023] The artificial breeding method of the blind stink bug parasitoid --- the red-necked often chambered wasp is carried out according to the following steps:

[0024] (1) Put 50-200 healthy adults of Lygus lygus into the insect breeding box, sterilize the fresh green beans, cut off the pods, put them in the insect raising box, replace fresh sterilized green beans every other day, and sterilize the fresh green beans produced by the green Lygus. The pods behind the eggs are placed in a ventilated and cool place, and after the surface of the eggs is dry, they are put back into the insect-raising box, and the relative humidity of the insect-raising box is controlled to be 60%. After 7 to 10 days, the eggs of the green Lygus hatch into nymphs;

[0025] (2) Add 5 to 15 curled paper strips to the insect raising box, put the nymphs into and add freshly sterilized green beans, put 50 Lygus nymphs into each insect raising box, and keep the relative humidity at 60% , the temperature i...

Embodiment 2

[0031] The artificial breeding method of the blind stink bug parasitoid --- the red-necked often chambered wasp is carried out according to the following steps:

[0032] (1) Put 100 healthy green Lygus adults into the insect breeding box, sterilize the fresh green beans, cut off the pods, put them in the insect raising box, replace fresh disinfected green beans every other day, and put the green Lygus after laying eggs Put the pods in a ventilated and cool place, put them back into the insect box after the surface of the eggs is dry, control the relative humidity of the insect box to 65%, and after 7 to 10 days, the eggs of Lygus green bugs will hatch into nymphs;

[0033] (2) Add 5 to 15 curled paper strips to the insect raising box, put the nymphs into and add freshly sterilized green beans, put 100 Lygus nymphs into each insect raising box, and keep the relative humidity at 70% , the temperature is 22°C, and freshly sterilized green beans are replaced every other day;

Embodiment 3

[0039] The artificial breeding method of blind stink bug parasitoid is characterized in that, according to the following steps:

[0040] (1) Put 200 healthy green Lygus adults into the insect breeding box, sterilize the fresh green beans, cut off the pods, put them in the insect raising box, replace fresh disinfected green beans every other day, and put the green Lygus after laying eggs Put the pods in a ventilated and cool place, put them back into the insect box after the surface of the eggs is dry, control the relative humidity of the insect box to 70%, and after 7 to 10 days, the eggs of the green Lygus hatch into nymphs;

[0041] (2) Add 5 to 15 curled paper strips in the insect raising box, put the nymphs into and add freshly sterilized green beans, put 250 green Lygus nymphs into each insect raising box, and keep the relative humidity at 80% , the temperature is 30°C, and freshly sterilized green beans are replaced every other day;

Abstract

The invention discloses a method for artificially raising plant bug parasitic wasps, which belongs to an artificial raising technology of natural enemy insects. In the method, Peristenus spretus is successfully bred by the following steps of: the inoculation of the Peristenus spretus, the raising of parasitized nymphae of green plant bugs, the pupation of parasitic wasps, the raising of adult worms and the like. The method is simple and easy, the occupied space is small, and the raising cost is low. By the method, the Peristenus spretus can be bred on a large scale to realize the uninterrupted breeding of the Peristenus spretus all the year around, so that the need of experimental study can be met, and a large number of insect sources can be provided for serious occurrence areas of plant bugs so as to reduce the harm of the plant bugs to crops such as cotton and the like.

Description

technical field [0001] The invention belongs to the artificial breeding technology of natural enemy insects, and in particular relates to an artificial breeding method of blind stink bug parasitic wasps. Background technique [0002] Cotton is an important economic crop in my country. With the continuous improvement of production conditions and the application of biotechnology in the field of cotton breeding, especially the commercial planting of Bt insect-resistant cotton in 1997, the types of pests and the degree of damage have changed significantly. Transgenic insect-resistant cotton can effectively control the damage caused by Lepidoptera pests such as cotton bollworm, pink bollworm and corn borer, but it has led to a series of succession of cotton field pests, blinding the secondary cotton pests that have been effectively controlled in the past. The population of stink bugs has increased dramatically, and it has become a dominant pest in cotton fields. With the ecologic...
