Tea geometrid parasitic wasp field trapping method

Abstract

The invention particularly relates to a tea geometrid parasitic wasp field trapping method. Tea tree pests-tea geometrids rampantly do harm in a tea region, important parasitic wasps-tea geometrid parasitic wasps in a tea garden parasitize and lay spawns in tea geometrid larva bodies, the density of the warps is low under the natural condition, and the tea geometrids cannot be effectively controlled. The method aims at effectively controlling the tea geometrids through the method of combining insect information matter with seduction. According to the technical scheme, the method comprises the following steps that 1, a parasitic wasp trapping agent is prepared from an odor source substance extracted from volatile gas released by tea trees; 2, the parasitic wasp trapping agent is injected into rubber heads to prepare trapping cores; 3, the trapping cores are placed on parrot green or light green or bud green color balls to form trapping devices; 4, the trapping devices are put into the tea garden to trap the tea geometrid parasitic wasps. The method has the advantages that the parasitic wasps around the tea garden are trapped in a short time, therefore, the tea geometrids are effectively controlled by the parasitic wasps, and chemical prevention and control are reduced; use is convenient and easy; the cost is low.

Description

Technical field [0001] The invention belongs to the technology of preventing and controlling tea looper tea pests, and specifically relates to a field trapping method for the tea looper parasitic wasp. technical background [0002] Since the 1970s, the tea tree pest, the tea looper, has been rampant in the tea areas of Zhejiang, Jiangsu and Anhui, and has gradually expanded to other tea areas. Tea looper belongs to the Insecta Lepidoptera Geometridae. It occurs 6-7 generations a year in Zhejiang Province, and 5-6 generations a year in Jiangsu, Anhui and Jiangxi. It feeds on the tender shoots of tea trees with larvae, and also eats when it occurs severely. Adult leaves and old leaves, and even gnaw on the bark, seriously affect the growth of tea trees. According to investigations, many tea farms have applied pesticides 7-10 times a year to prevent and control tea loopworms. Excessive use of chemical pesticides has killed a large number of natural enemies and reduced the biodivers...
