Description
Technical field
The present invention relates to agriculture deinsectization method, is a kind of method of killing roundheaded borer with microwave.
Background technology
Longicorn is the insect of extensively taking place in a kind of world wide, is the general name of coleoptera Chrysomeloidea Cerambycidae insect, and its host types is many; Harm extensively all can be infected by it like forestry, ornamental trees and shrubs and fruit tree etc., and it is hidden to have life style because of it again; The natural enemy kind is few, receives characteristics such as the interference of natural cause is little, the very difficulty so control is got up; Often cause wildness to cause harm, or even deforestation.The larva of longicorn is a vermiform, can pierce in the tree to live more than 2 years, and newly hatched larvae is got food under bark, along with the increase in the length of time, promptly pierces to get in phloem and the xylem to eat and causes harm, and destroys the trees conducting tissue, causes trees withered or died.At present the disclosed method of killing roundheaded borer mainly contains three kinds: a kind of is that artificial mechanism is catched and killed: comprise that hook kills larva, strikes off worm's ovum, catches and kills adult and trunk and whitewash etc., the deficiency of this method is: workload is very big, but insecticidal effect is not good enough; Another kind method is biological disinsection method: like larva and the pupa with the parasitic longicorn of the swollen leg honeybee of Guan Shi; Protect and attract woodpecker, attract ant predation roundheaded borer; This method receives natural conditions (for example temperature, wind-force etc.) on promoting the use of restriction is very big, have little effect; Cost is very high, take effect slow, difficult the popularization; The most frequently used is chemical disinsection method: this method need be used some highly toxic pesticide: Rogor, dichlorvos or flolimat etc. inject worm channel, reach the desinsection purpose, and this method is because simple and easy to do; Effect significantly is widely used, and still, the harmfulness of this method is very big; Pesticide resistance along with roundheaded borer produces causes spraying medicine concentration to improve constantly, and is more and more serious to the pollution of environment; Simultaneously, go back the serious harm human and livestock health.
Summary of the invention
