Embodiment 1

[0027] Embodiment 1 The influence of different host plants on the nymph survival rate, duration and single female oviposition of Amaryllis lycoides

[0028] The common and best-selling succulent varieties suitable for Amaryllis lycoccus and black mage, lettuce leaves, tomato leaves, potato leaves and germinated potatoes were selected as host plants, and the survival rate and development of the mealybug on different host plants were compared. duration and fecundity to determine the most suitable host. Among them, the succulent plants (Ji Luyue and Hei Mage), lettuce leaves, tomato leaves and potato leaves are treated by hydroponics, and the germinated potatoes are whole potatoes with a sprout length of 1-2 cm. Treatment of hydroponic host plants: select plant tissues with a total length of stems and leaves of 10 cm, wrap the lower end with absorbent cotton, and then insert them into a vertically placed test tube with an outer diameter of 1.5 cm and filled with clean water.

Embodiment 2

[0039] Example 2 Effects of Different Stocking Densities on the Escape Rate, Development and Reproduction of Lycoris lycoris

[0040] 5, 10, 15, 20, 25, 30, 35 and 40 newly hatched nymphs of P. amaryllis were respectively connected to one germinated potato. After 24h, 48h and 72h, the number of remaining mealybugs was counted, and a single potato was analyzed Optimal number of infestation. Each treatment was repeated 3 times.

[0044] Note: Different lowercase letters indicate significant differences among treatments, the same below.

[0045] It can be seen from Table 2 that after 24 hours of inoculation, the number of mealybugs remaining on potatoes gradually increased as the number of inoculations increased, but when the number of inoculations exceeded 30, the proportion of successful inoculations gradually decreased; After 48 and 72 hours of infestation, the number ...

Abstract

The invention relates to the technical field of indoor breeding of insects, in particular to an indoor subculture breeding method of Phenacoccus solani Ferris. The method comprises the following steps: firstly, collecting plants which are damaged by the Phenacoccus solani Ferris in the field, taking the plants back to a room, and classifying the Phenacoccus solani Ferris on the plants according to individual sizes; then, in an artificial climate chamber, inoculating germinated potatoes with the same size of the Phenacoccus solani Ferris until the Phenacoccus solani Ferris is developed into female adults; next, gently transferring the female adult Phenacoccus solani Ferris to the clean germinated potatoes by using a soft writing brush, and after the female adult Phenacoccus solani Ferris is spawn, the spawn is hatched into one-year-old nymphs and molted into two-year-old nymphs, putting the fresh and clean germinated potatoes next to the newly molted two-year-old nymphs, and enabling the newly molted two-year-old nymphs to naturally climb to fresh host plants; and finally, when a proper amount of 2-year nymphs of the Phenacoccus solani Ferris are overgrown on the new germinated potatoes, transferring the germinated potatoes to a new insect breeding cage, and repeating the operation to realize indoor subculture breeding of the Phenacoccus solani Ferris. According to the method, the germinated potatoes are adopted to breed the Phenacoccus solani Ferris, and the method is simple and easy to operate. According to the method, the developmental duration of the Phenacoccus solani Ferris is remarkably shortened, the single female spawning amount is increased, and the breeding efficiency is greatly improved. Moreover, as food addicting hosts of the Phenacoccus solani Ferris, the germinated potatoes are easy to obtain and convenient to store, so that greatly reduce the feeding difficulty and cost.

Description

technical field [0001] The invention relates to the technical field of indoor breeding of insects, in particular to an indoor subculture method for the alien invasion organism Lycoccus lycoris. Background technique [0002] Phenacoccus solani Ferris (Phenacoccus solani Ferris) belongs to Hemiptera (Hemiptera), Pseudococcidae (Pseudococcidae), Phenacoccus (Phenacoccus), is a serious threat to Chinese medicinal materials, garden ornamental plants and Invasive pests for the safe production of economic crops such as vegetables, a total of 131 species of plants in 40 families are harmed by this insect in the world, and they especially like to eat Solanaceae, Compositae and succulents. At present, the insect has caused damage in Beijing, Xinjiang, Taiwan, Zhejiang, and South China, and has a tendency to spread further. Lycoccus lycoccus mainly sucks the juice of the young parts of the host plant in the form of female adults and nymphs, which makes the damaged plants stunted in gr...
