Description

Bombycis Mori mature larva pupation device

Technical Field

The utility model belongs to the technical field of experimental device, specifically be a fall webworm mature larva pupation device.

Background

Hyphantria cunea (Drury) belongs to Lepidoteera and Arctidae, and is an important international quarantine pest. Because it has the characteristics of food impurity, large food intake, strong reproductive capacity, wide adaptability, high propagation speed, serious harm and the like, it becomes a significant foreign invasive pest in China and is the most dangerous invasive species at home and abroad at present. The fall webworms are native to North America, distributed in the northern latitude of 19 degrees to 55 degrees, and then introduced into Europe and Asia. Since the first discovery of the fall webworms in Dandong City of Liaoning province in 1979, the epidemic areas of China have spread to 586 county-level administrative districts of 13 provinces (city, autonomous region), and huge damage is caused to forest resources and ecological environment. The fall of the hyphantria cunea host is wide, and researches in recent years show that the fall of the hyphantria cunea host is continuously expanded, and 630 various hosts are harmed worldwide, wherein more than 300 hosts are harmed in China. The favorite tree species include poplar, mulberry, phoenix tree, Chinese ash, willow, locust tree, camptotheca acuminata, ailanthus altissima and other broad-leaved tree species. Besides trees and trees, the fertilizer also harms crops and vegetables. The larva of the fall webworm has large food intake, and can eat the leaves of the whole plant overnight during a major outbreak, so that the plant grows and develops badly, and even the tree dies and crops are not harvested when the plant grows badly, so that the serious loss is caused.

In order to prevent and control the quarantine pests worldwide, the biological characteristics and the life habit of the fall webworms need to be researched newly, the metamorphosis mode of the fall webworms belongs to the full metamorphosis type, and the fall webworms can live through four insect states of eggs, larvae, pupae and imagoes. Pupation of larvae is an important link in the growth, development and metamorphosis process, and before pupation, aged larvae are put on trees to find warm, dry, dark and hidden pupation places, such as stone heaps, tree holes, underground shallow soil, old and thick bark seams, withered branches and fallen leaves layers or straws of crops. Under the laboratory condition, because no proper pupation device provides mature larva pupation, the pre-pupation is often exposed in an open environment during the pupation process, so that the pupation process is easy to be infected by diseases or generate abnormal pupation, and the subsequent research on the white moth pupae and imagoes of America is influenced.
