Description

Device is raised to fall webworm larva

Technical Field

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

Background

The fall webworm Hyphantia cumea (Drury) belongs to Lepidoptera and Conidioidae, and is a world quarantine pest with polyphagia, multiple hosts and wide distribution range. Since the first discovery of the American white moth in the Dandong area of Liaoning province in China in 1979, the American white moth is successively propagated and diffused to provinces and markets such as Beijing, Tianjin, Hebei, Shandong and Jiangsu, etc. By the end of 2018, the fall webworm epidemic area has been related to 586 county-level administrative districts of 13 provinces (district, city) in Beijing, Tianjin, Hebei, inner Mongolia, Liaoning, Jilin, Jiangsu, Anhui, Shandong, Hubei and Henan.

The fall webworm has wide hosts, strong reproductive capacity, strong adaptability and multiple propagation ways, is mainly harmful to various trees and fruit trees, and leaves can harm nearby crops, vegetables and wild plants after eating. Many hosts 630 can be harmed worldwide, with up to more than 300 in China. In order to control and cope with such quarantine insects worldwide, research on fall webworms is urgently needed. Firstly, starting from the biological characteristics and the life history of the hyphantria cunea, and ensuring that enough insect sources to be tested exist under the laboratory conditions, the hyphantria cunea is simply raised under the current experimental conditions, and mainly comprises a raising box and an insect cage. Under traditional box condition of raising, the environment is airtight, breeds the pathogenic bacterium easily, and the excrement and urine is cleared up inconveniently and is led to the larva and easily infects the pathogenic bacterium and die. And the water loss of the leaves is too fast under the condition of the insect cage, so that the larvae are not beneficial to taking food, and the normal growth and development of the larvae are influenced. The experiment is smoothly carried out, so that great inconvenience is caused.

the utility model provides a device is raised to fall webworm larva, includes the box, takes out board, moisturizing box and blade, it is penetrating about the box, there is the apron box top through hinge connection, and is provided with the sliding tray below two walls of box, the box is inlayed through the sliding tray and is had the board of taking out, one side of box is provided with 3-4 round holes, is provided with the boss in the corresponding outside of round hole, and is provided with the external screw thread on this boss, one side of box is provided with the moisturizing box, and is provided with the internal thread on the moisturizing box, be provided with moist cotton in the moisturizing box, and moist cotton is connected with the blade that has the petiole through the rubber band, and the blade sees through the round hole and installs the inboard at the box.

Furthermore, the distance between the sliding groove at the lower end of the box body and the ground is 4-6 cm.

Furthermore, the drawing plate and the box body form a sliding structure through a sliding groove, and one end of the drawing plate is provided with a handle.

Furthermore, a plurality of round holes are uniformly arranged on the drawing plate.

Furthermore, the top of moisturizing box is provided with the opening, and the internal thread of moisturizing box and the external screw thread phase-match of box boss.

Furthermore, the blades are movably connected with the wet cotton.

Has the advantages that: compared with the prior art, the method has the following advantages:

this device is raised to fall white moth larva bottom is provided with and takes out the board, it does benefit to the air flow to take out a plurality of small circles holes of board, it is normal to guarantee that the larva breathes, when clearance excrement and urine, only need take out the board and take out and pour away can, and the small circle hole in bottom also can be through rocking the box body at ordinary times, suitably clearance excrement and urine, the blade setting is in the open-air habitat of box top at the at utmost simulation, make things convenient for the white moth larva in the united states to get from the leaf back and eat, and larva excrement and urine can fall to the bottom thereupon, prevent that excrement and urine from making the larva illness, the vitality of.
