Problems solved by technology

Although in the laboratory, Chow's gnats have a good parasitic effect on Yang Xiaozhou moth, but in actual application, due to the large environmental space, it is difficult for Zhou's gnats to find or find Yang Xiaozhou moth, so the control effect is not good. good

Embodiment Construction

[0022] Specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0023] 1. The source of Chow's gnat

[0024] Donated by the Beijing Forestry Biological Control Research and Promotion Center of the Zhou's gnat, the tussah pupae parasitized by the Zhou's gnat were placed in a constant temperature incubator with a temperature of 25±1°C, a humidity of 65%, and L:D=14:10 cultivated within. After eclosion, active female bees were selected for behavioral measurement.

[0025] 2. Attractants

[0026] The present invention selects 7 kinds of attractants, see Table 1, and 4 kinds of mixtures, mixture one ((E)-2-hexenol, (E)-2-hexenal and (Z)-acetic acid of equal volume and concentration -2-hexenyl ester mixture), mixture two (equal volume and concentration of (E)-2-hexenol and (Z)-acetic acid-2-hexenyl ester mixture), mixture three (equal vo...

Abstract

The invention discloses an attractant for Chouioia cunea Yang, and an application thereof, and belongs to the field of poplar leaf-eating pest control. The attractant for Chouioia cunea Yang is one ormore of (E)-2-hexenol, (E)-2-hexenal, (Z)-2-hexenyl acetate, hexyl acetate and linalool. The attractant is sprayed or smeared on poplars suffering from leaf-eating pests to effectively attract Chouioia cunea Yang released in the environment or manually, and is used for parasitizing poplar pests, especially Micromelalopha troglodyta, so that the purpose of preventing and controlling the poplar pests is achieved; and the attractant has the advantages of simplicity in operation, no pollution, environmental friendliness, low cost, high pertinence and good effect.

Description

technical field [0001] The invention relates to the field of prevention and control of poplar leaf-eating pests, in particular to an attractant for Chow's gnats and an application thereof. Background technique [0002] Chouioia cunea Yang belongs to the Hymenoptera, Chouioia cunea Yang, Eulophidae. This parasitic wasp has high parasitic rate, strong fecundity, and large sex ratio. It has all the advantages, and has a wide range of parasitism. It can parasitize a variety of Lepidoptera leaf-eating pests. It has broad application prospects in the biological control of forest pests (Peng Jinyou et al., 2004). It is a dominant parasitoid. [0003] Micromelalopha troglodyta (Graeser) is one of the main leaf-eating pests of poplar in my country. It is rampant in the northeast, northwest, central plains and central south of China. It not only affects the normal growth of poplar, but also causes huge economic losses. Destroying the ecological environment has seriously restricted the...
