Indoor feeding and life history observation method of bark beetle

Abstract

An indoor feeding and life history observation method of a bark beetle belongs to the technical field of insect feeding and control and solves the problem that observers cannot observe life habits such as gallery building, mating, oviposition, feeding and growth of larvas and life history of the bark beetle by means of an existing indoor bark beetle feeding technology. The method comprises the following steps: (1) preparation of a host wood section, (2) preparation of an insect feeding cage, (3) collection of imagoes, (4) insect receiving and feeding, (5) observation of the characteristics of imago intruding holes and mother galleries and observation statistics of oviposition quantity, (6) inoculation of eggs and observation of incubation behaviors, (7) observation of feeding behaviors and characteristics of son galleries, (8) inoculation of pupas and observation of pupation behaviors and (9) inoculation of imago eclosion. The method enables the observers to conveniently track and observe life habits and states of an imago stage, an egg stage, a larva stage and a pupal stage of the bark beetle, and provides scientific evidence for comprehensive control of the bark beetle.

Description

Technical field [0001] The invention belongs to the technical field of insect biological control, and particularly relates to an indoor breeding method of insects. Background technique [0002] Bark beetles belong to the Coleoptera and Toxicidae family. There are more than 6000 species. There are about 500 species in China, most of which are important forest pests and quarantine pests. Tobacco beetles mostly live in the bark or heartwood. They have strong reproductive power and a wide range of hosts. The damage is difficult to detect in the early stage. Once an outbreak occurs, it is difficult to control and often cause forests to wither or die. For example, bark beetles on pine trees are called "cancers of pine trees" because of their serious damage and difficult control. Bark beetles are concealed and can spread along with the transportation of the original host tree species, wood, seedlings, and wooden packaging. Many species such as red beetles and heteropterans are also imp...

Problems solved by technology

[0004] In order to solve the problem that the existing indoor bark beetle breeding technology cannot observe the living habits and life history of bark beetles such as building tunnels, mating, laying eggs, feeding and growth of larvae, and it is difficult to obtain data close to natural habits. The present invention provides A method for indoor breeding and life history observation of bark beetles, the technical scheme of which is as follows:
