Method for luring, catching and killing citrus black cicadas

Abstract

The invention discloses a method for luring, catching and killing citrus black cicadas. A feasible method for luring, catching and killing nymphs does not exist at present. The method comprises the steps of laying straws and applying barnyard manure in furrows around citrus trees or pomelo trees according to life habits of black cicada larvas and nymphs, creating appropriate soil conditions and living environments and then luring, catching and killing the nymphs. The luring rate is improved by more than double through comparison. Simultaneously, the catching and killing time and measures of lured nymphs are limited and stipulated strictly. The yield of citrus orchards (or pomelo orchards) and nearby citrus orchards is improved by 19%-28.5% through comparison after the nymphs are lured, caught and killed. Furthermore, the income gained by selling the nymphs can be increased, and the economic benefit is obvious.

Description

technical field

[0001] The invention relates to a method for luring and killing citrus pests Cryptotympana atrata Pabricius, in particular to a method for luring and killing nymphs of Cryptotympana atrata Pabricius, reducing the degree of damage and increasing the yield of citrus. Background technique

[0002] Black Grasshopper Cicada (Cryptotympana atrata Pabricius), also known as Grasshopper Cicada, Cicada, etc., belongs to Homoptera, Cicadae. Adults in summer feed on the sap of citrus twigs, often causing a large number of fruit drop and twig death. In orange orchards where black grasshopper cicada re-emerged, the plant damage rate reached 100%, causing large losses.

[0003] Adults are black or dark brown, shiny, with a lifespan of 60 to 70 days. It appears from May to August every year, and when the average temperature reaches 22°C, the chirping of cicadas begins. Females lay eggs in the xylem of branch shoots from June to August (usually in the summer and autumn sho...
