Method for preventing and treating Shatian pomelo cicada nymphs

Abstract

The invention discloses a method for preventing and treating Shatian cicada nymphs. In a cicada nymph harm period, a layer of smooth plastic thin film is bound at the root of a Shatian pomelo tree, which is at a distance of 5 to 10cm from the ground; a width of the thin film is 5 to 10cm; an attractant or sex pheromone is sprayed on the surface of the thin film. Under the attraction of the attractant or sex pheromone, a great amount of cicada nymphs crowd around the Shatian pomelo tree at night or before early morning. However, due to smoothness of the plastic thin film, the cicada nymphs cannot climb branches by the plastic thin film, a great amount of cicada nymphs can be gathered around the root of the Shatian pomelo tree, and the moment is the best opportunity of artificial capture. Hazard of the cicada nymphs is prevented and treated by utilizing the method; the method is simple and easy, convenient to take materials and low in cost, not only kills the cicada nymphs and protects the tree, but also does not pollute the environment, is not only simple and convenient, but also safe, and has an excellent effect.

Description

technical field [0001] The invention relates to the technical field of fruit tree pest control, in particular to a method for controlling pomelo cicadas in Shatian. Background technique [0002] The law of occurrence of cicadas generally just occurs one generation every 3 to 5 years, and survives the winter in the branches with eggs or with nymphs in the soil. The adults of cicadas occur from June to September, and flourish in July to August. Oviposition is in the branch xylem of the current year, and August is the peak oviposition period. Eggs are mostly produced on the terminal shoots of 4 to 5 mm and on the branches of the ears. The adult lifespan is more than 2 months, and the egg period is 10 months. In June of the following year, the nymphs hatch and land in the soil to damage the roots. After autumn, they go to the deep soil layer to overwinter, and the spring warms to the cultivated layer. After several years, the mature nymphs climb to the trunk or On twigs, molts...

AI Technical Summary

Problems solved by technology

Because the insect body is protected by a foam layer, conventional control methods such as pesticide spraying, the liquid is difficult to reach the base of the fruit tree, and fumigation is used to smoke, and the drug smoke is difficult to penetrate the foam protection layer

Traditional control methods are not effective and cannot achieve effective control

However, the application of chemical agents to prevent pomelo cicada pests in Shatian is costly and ineffective, and it will cause problems such as pesticide residues, environmental pollution, and insect resistance, which will affect the quality and make it difficult to meet the requirements of "green food".
