Embodiment Construction

[0039] From December 2001 to December 2004, the insect breeding room of the Institute of Forest Protection, Yunnan Academy of Forestry used the "Indoor Feeding and Life History Observation Method of Bark beetles" for three consecutive years to conduct breeding observations on Tomicus yunnanensis, including The continuous rearing and follow-up observation of eggs, larvae, pupae and adults basically clarified the life habits and life history of Tomicus yunnanensis, and provided scientific basis for the control and in-depth study of the insects. The breeding and life history observation method includes the following steps:

[0040] (1) Preparations for receiving host:

[0041] Harvest healthy Yunnan pine trees with a DBH of 5-10cm from the Arboretum of the Provincial Academy of Forestry or nearby forests, and cut them into sections with a length of 20-80cm. The cuts at both ends are painted with white latex and affixed with kraft paper for use. , The purpose is to prevent the moistur...

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...
