Technique for artificial propagation of apriona dastarcus helophoroides and preventive treatment of apriona swainsoni hope

Abstract

The invention discloses a technique for the artificial propagation of apriona dastarcus helophoroides and the prevention and treatment of apriona swainsoni hope. The technique comprises the following steps that: firstly, breeding and induced spawning are carried out to the imago of apriona dastarcus helophoroides in an environment with the environmental temperature at 251 DEG C and the humidity of 602%; after an egg is hatched into the larva of the dastarcus helophoroides, the larva is inoculated on a substituted host and becomes the imago by development and emergence eclosion; the imago or the egg of the shoulder apriona dastarcus helophoroides can be released to prevent and treat apriona swainsoni hope and can be prepared into an egg releasing card or an imago releasing bag for releasing or cold-storage standby; a favourable preventive treatment effect can be achieved after releasing; and by releasing the apriona dastarcus helophoroides in the same year, the parasite rate of the larva and the pupa of the apriona swainsoni hope reaches 65.7%. By utilizing the biological preventive treatment technique of the invention, the apriona swainsoni can be effectively prevented and treated, the injury of the apriona swainsoni hope is controlled, injurious insects are effectively controlled under the premise that the environment is protected and the ecological balance is maintained, and the preventive treatment problem that the important forest and garden injurious pest has great harm and is very difficult to be prevented is solved.

Description

technical field [0001] The invention relates to a biological control technology, in particular to a technology for artificially propagating the long beetle beetle and preventing and controlling the rust-colored long beetle. Background technique [0002] Apriona swainsoni Hope (Apriona swainsoni Hope) belongs to the genus Apriona of the family Cerambycidae (Cerambycidae) of the order Coleoptera. "Guo Huai Killer". Rusty beetle also harms willow (Salix) tree, rosewood (Dalbergia hupeana), cloud fruit (Caesalpiniasepiaria), black locust (Robinia pseudoacacia) and other tree species. Rust-colored beetle larvae bore into the trunk of the host tree to feed, destroy the tree's transport tissue, and often form irregular horizontal flat worm tracks on the cambium and sapwood, seriously affecting the growth and development of the tree. The tree vigor is weakened, the leaves turn yellow, and the branches are dry. In severe cases, the epidermis and the xylem are separated, and the epi...

Problems solved by technology

It is difficult for chemical control and other control methods to contact the insect body and effectively kill the beetle larvae, so the control effect is very poor, and chemical control pollutes the environment
