Embodiment Construction

[0016] The present invention is described in further detail below in conjunction with embodiment. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] 1. Select woodland: choose a woodland with American white moth screens, a rate of insects below 10%, and an average population density of 10 to 20 insects / plant. We set up two-year-old ash trees in saline-alkali soil, 107 poplars in sandy loam soil, and apple trees in loam soil. Set up 10 survey points for each tree, and set up treatment controls according to the same standard.

[0018] 2. Suspension of tussah silkworm chrysalis parasitized with the white moth Chow's gnat: mix and match multiple tussah chrysalis with the white moth Chow's chrysalis parasitized and with a time difference of 5 to 7 days, and then hang them on the same plant. Among them, the ratio of tussah silkworm chrysalis that was born early by the whi...

Abstract

The invention discloses a novel method for preventing hyphantria cunea by means of Chouioia cunea Yang. The method mainly includes steps of selecting a forestland, hanging tussah pupa with the parasitic Chouioia cunea Yang and releasing the Chouioia cunea Yang. According to the method, the Chouioia cunea Yang with the intervals of the bee born time from 5-7 days are released for one time to prevent the hyphantria cunea, and the difference of the bee born time of the Chouioia cunea Yang ranges from 5 days to 7 days; the parasitic rate of the Chouioia cunea Yang on the hyphantria cunea is high, the control efficacy is good, and the control is complete; and the control cost is low, and the method is simple in using, obvious in economic benefits, ecological benefits and social benefits, good in popularization and application prospects and capable of protecting natural enemies of the hyphantria cunea from being killed.

Description

technical field [0001] The invention relates to the technical field of white moth prevention and control, in particular to a new method for controlling the white moth by using the white moth C. Background technique [0002] American white moth Hyphantria cunea (Drury), also known as American lamp moth, autumn curtain caterpillar, autumn curtain moth, belongs to Lepidoptera, Diphridae.
