Embodiment 1

[0064] (1) Collection of the provenance of the square head beetle and the intermediate host Scutellaria:

[0065] On the plants in the citrus orchards that were harmed by the shield scale pest, the eggs, larvae, pupae or adults of the square head and the intermediate host, the oriental kidney scale, were collected respectively, and brought back indoors as a seed source for future use.

[0066] (2) Reproduction of intermediate hosts:

[0067] First, wash the potatoes, spray them with disinfectant water or wash them in disinfectant water, and then dry them for later use. Then, sweep the newly hatched nymphs of Coccus orientalis on the potatoes with a brush. There are 180 to 200 nymphs on each potato. Potatoes with nymphs are placed under the conditions of temperature 27-30°C and humidity 65-70%, allowing them to develop freely. After 20 days, take them out for later use, and leave a part as a provenance to propagate the next generation of oriental shield scale.

Embodiment 2

[0075] (1) Collection of the provenance of the square head beetle and the intermediate host Scutellaria:

[0076] The eggs, larvae, pupae, or adults of the square-headed beetle and the intermediate host, the oriental pancreas, were collected from the plants in the pine forest that were harmed by the shield scale pest, and brought back indoors as a seed source for future use.

[0077] (2) Reproduction of intermediate hosts:

[0078]First, wash the potatoes, spray them with disinfectant water or wash them in disinfectant water, and then dry them for later use. Then, sweep the newly hatched nymphs of Coccus orientalis on the potatoes with a brush. There are about 190 to 210 nymphs on each potato, and then put Potatoes with nymphs are placed under the conditions of temperature 25-28°C and humidity 72-75%, allowing them to develop freely, taking them out after 25 days for use, and leaving a part as a provenance for breeding the next generation of oriental scutellaria orientalis;

Embodiment 3

[0086] (1) Collection of the provenance of the square head beetle and the intermediate host Scutellaria:

[0087] On the garden plants cycads or cactus plants that are harmed by the shield scale pest, collect the eggs, larvae, pupae or adults of the square head and the intermediate host, the oriental kidney scale, respectively, and bring them back indoors as a source for future use.

[0088] (2) Reproduction of intermediate hosts:

[0089] First, wash the potatoes, spray them with disinfectant water or wash them in disinfectant water, and then dry them for later use. Then, sweep the newly hatched nymphs of Coccus orientalis on the potatoes with a brush. There are 200 nymphs on each potato. The potatoes were placed under the conditions of temperature 27-30°C and humidity 76-80%, and let them grow freely. After 28 days, they were taken out for later use, and a part was left as a provenance to propagate the next generation of oriental shield scale;

Abstract

The invention belongs to the technical field of biologically controlling agricultural and forestry pests, and in particular relates to a method for the indoor propagation and the outdoor release of natural enemy insects. The method comprises the following steps of: using potatoes as a propagation material of an intermediate host; using oriental kidney armored scales which are easy to mass propagation indoors and have wide humiture adaptation range as the intermediate host, putting the intermediate host cultured for about 20-30 days in a disposable cup with a lid, inoculating and propagating acybocephalus seed source in a sex ratio of 1 to 1, taking out the cybocephalus seed source after 10-15 days and transferring to another cup until the seed source is dead; putting the rest potatoes inrows in a plastic box with bilayer gauze on the bottom layer to collect pupas; and putting the collected pupas in an adult insect collecting cage or releasing the pupas in the field so as to prevent armored scale pests or releasing the collected adult insects in the field. The invention can carry out the mass production on the cybocephalus and solve the problems of low propagation efficiency and annual productivity incapability of the cybocephalus.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural and forestry pests, and relates to a method for indoor breeding and field release of square-headed beetles. Background technique [0002] Coccidae is the most diverse and most evolved group in the Homoptera Chronocystis. It is widely distributed all over the world, especially in Asia, Europe and Africa. At present, 372 genera and 2,088 species of Coccidae have been recorded, accounting for one-third of the species of Coccoids, and there are more than 320 species of Cocoids known in China, which mainly parasitize various trees, shrubs and herbaceous plants. , fruit trees, commercial crops and ornamental plants are important pest groups. Due to the special morphological structure of shield scale pests, chemical control is very difficult, and the economic losses caused cannot be estimated. There are abundant natural enemy resources of the shield scale insect, and the squa...
