Abstract

The invention relates to a device for determining the influence of an insecticide on the host positioning capability of aleyrodid pest parasitic wasps and a use method. The device comprises an activated carbon gas washing chamber, a gas flowmeter, a liquid gas washing bottle, determination pipes and a sucking pump. A parasitic wasp access port to be measured is formed in the right side of the bottom of a measuring tube body, and a volatile matter access port related to parasitic wasp host positioning is formed in the left side. There are four determination pipes which can be used for observingfour parasitic wasps at the same time. The determination pipes are placed on the pipe rack, and the isolation baffles are arranged among the determination pipes so that learning behaviors between theparasitic wasps can be effectively avoided. A long glass tube is used as a main measuring instrument, a general device for measuring the olfactory response of insects is mainly used for measuring theselectivity of insects to different substances, and the change of parasitic wasps to the host positioning time under the influence of insecticides is emphatically measured.

Description

technical field [0001] The invention belongs to the technical field of insect behavior observation, and in particular relates to a device for measuring the influence of insecticides on the host positioning ability of whitefly pest parasitoids. Background technique [0002] Natural enemy insects are one of the natural regulators of pests and an important natural control factor in the change of pest populations. Whitefly parasitic natural enemies are various and rich in resources. At present, more than 50 species of whitefly parasitoids have been reported at home and abroad, of which 35 belong to the family Aphelinidae (Aphelinidae) Encarsia, 15 species belong to the genus Eretmocerus, 3 species belong to the genus Amitus, 2 species belong to the genus Signiphora, and 1 species belongs to the genus Metaphycus, The species of its parasitoids are still increasing. my country is relatively rich in resources of whitefly parasitoids. It has been reported that there are 27 species...
