Problems solved by technology

Unreasonable use of drugs has killed a large number of natural enemies, seriously damaged the ecological balance of the farmland ecosystem, and lost the natural control ability
The large and continuous use of chemical pesticides also leads to the emergence of pest resistance, and even leads to the situation where no pesticides are available
At the same time, it will also lead to serious pesticide residue problems, causing pesticide residues in crops to exceed the standard, posing a serious threat to human health
Borers are mostly borer pests, and their damage is hidden. Only a few insecticides with strong systemic permeability and special effects on Lepidoptera insects are suitable for the control of borers, and the control effect is not good.

Embodiment Construction

[0012] In this experiment, aiming at ecological and social problems such as the increasingly serious damage of the main rice pest, the rice stem borer, the pest resistance caused by the abuse of chemical insecticides, the residue of rice pesticides, and environmental pollution, a simple and easy-to-promote ecology of the rice stem borer is proposed. The control method is to plant a certain proportion of insect-attracting plants on the ridges around the paddy field to induce the C. borer to lay eggs on the plants and kill the larvae intensively, so as to reduce the damage of the C. borer in the paddy field and reduce the use of pesticides. These tests are only the embodiment of some specific implementation examples, and cannot limit the protection scope of the present invention in any way.

[0013] Trial 1, spawning selection trial.

[0014] The test was carried out in a dark insect culture room at 26±1°C, RH80-90%. Place two pots of 45-day-old sudan grass and 60-day-old TN1 ...

Abstract

The invention provides a plant for luring and killing stem borers, and a using method thereof. The method comprises the following steps: Sudan grass is planted around mainly planted crops or is planted alternately with the mainly planted crops; the stem borers are lured into laying eggs or staying on the Sudan grass by utilizing the special luring capability of the Sudan grass to the stem borers;and then the Sudan grass is intensively removed or the stem borers on the Sudan grass are directly killed so as to control the harm of the stem borers to the mainly planted crops. The method has the characteristics of labor conservation, time conservation, simple operation, no environmental pollution and the like.

Description

technical field [0001] The invention relates to the technical field of ecological control of agricultural pests, in particular to a method for controlling stem borers by using an insect-attracting plant, sudan grass. Background technique [0002] In recent years, due to the adjustment of planting structure, the change of farming system, the replacement of varieties, climate change and the increase of drug resistance, etc., the population of stem borers has shown a significant upward trend. At present, the use of chemical insecticides is still the main means of borer control, and the frequency of application is high and the amount of application is large. Unreasonable use of drugs has killed a large number of natural enemies, seriously damaged the ecological balance of the farmland ecosystem, and lost the natural control ability. The large and continuous use of chemical pesticides also leads to the emergence of pest resistance, and even leads to the situation that no pestici...
