Embodiment 1

[0027] In March 2012, potted tea trees were pruned in batches and sprayed with plant growth regulators (800mg gibberellin and 100mg indole acetic acid dissolved in 5% ethanol aqueous solution). After 10-15 days, the tea buds will be drawn. After about 25 days, the tea buds grow to about 4cm, and there are about 30 tea buds in one pot of tea trees. At this time, ten pots of tea trees are moved into the insect culture room. On April 4th, the last instar nymphs of the small green leafhopper with false eyes were collected from the tea garden and planted on these ten pots of tea trees. The environmental conditions in the insect culture room are temperature 24-27°C, relative humidity 60%-80%, natural light cycle, and 30 pots of potted tea trees are placed. Within one to three days after the insertion of the last instar nymphs, the nymphs emerge one after another. On April 20, the first instar nymphs could be observed from these ten pots of tea trees, and the number of nymphs began...

Embodiment 2

[0029] Grab 50 last-instar nymphs from the tea tree in the insect culture room, and raise them in a bottomless glass tube. One end of the bottomless glass tube is wrapped with 100-mesh gauze, and the other end is tightly plugged with moist cotton. The handle end of the tea bud in the glass tube is in contact. Cotton maintains vitality by absorbing moisture, and when the tea buds in the tube are severely damaged, they are replaced. After eclosion, male and female were paired for mating test. The results showed that the adult green leafhoppers reared indoors can observe mating behavior 4 to 5 days after eclosion, that is, they are considered to have reached sexual maturity at this time. It varies from 180 minutes. After mating, the females are placed on the hydroponic tea branches, and after about 6 days, the first instar nymphs can be seen on the tea branches. The adult worms after mating continue to be reared with a single head in a glass tube, and most of them can survive f...

Embodiment 3

[0031] When the number of tea buds on a single tea branch reaches 10 and the tea buds grow to about 4cm, the tea branches are cut off, and the length of the tea branches is controlled within the range of 10cm (after deducting the length of the tea buds). The ends of the tea branches were cut into a wedge shape, and the wounds were soaked in 0.5% potassium permanganate for disinfection. Then insert these tea sticks into a plastic foam (fixed tea sticks) one by one, ten tea sticks per pot, with about 5cm exposed at the end of the tea sticks, soak them in a square dark plastic basin (40cm long, 40cm long, Width 20cm, height 10cm), a small rubber tube is passed into the nutrient solution, and an air pump is connected to ensure the oxygen content in the nutrient solution. The environmental conditions are: temperature 24-27 ℃, relative humidity 60%-80%, natural light cycle. On the hydroponic tea branch, insert 10 female adults of the small green leafhopper just about to lay eggs. ...

Abstract

The invention provides an ideal food source and an inhabiting place for tea green leafhoppers by means of auxin, water culture and the like. Indoor year-feeding of the tea green leafhoppers is achieved. Meanwhile, the method for feeding imagoes without copulation and scientific testing tea green leafhoppers with the identical age in days is invented on this basis. Seasonal fluctuation of the number of tea green leafhopper groups is avoided. A guaranteed stable tea green leafhopper source is provided for relative research of the tea green leafhoppers.

Description

technical field [0001] The present invention relates to a series of leafhoppers with false eyes ( Empoasca vitis G?the) indoor perennial subculture breeding method, belonging to the field of experimental insect breeding. Background technique [0002] Leafhopper with false eyes ( Empoasca vitis G?the) belongs to the order Hemiptera, the cephalozoan suborder Leafhopper superfamily, and the leafhopper is an insect. Since the 1960s, it has gradually become one of the main pests in tea gardens in my country. The main way of damage is to suck the juice of new shoots and leaves of tea trees with piercing-sucking mouthparts. This method of damage seriously affects the output and quality of tea leaves. According to statistics, it can generally cause a reduction of about 15% in production, and even 50% in severe cases. For a long time, due to the lack of plant protection knowledge, tea farmers blindly used a large amount of chemical pesticides to control tea tree pests, resulting i...
