Method for improving sesamia inferen control effect by coordinative application of trap crop and sex attractant

Abstract

The invention provides a method for improving sesamia inferen control effect by coordinative application of trap crops and a sex attractant. The method comprises: planting trap crops in lines on ridges of a rice field or a zizania aquatica field, clump distance of the trap crops being 3-4 m, trapping sesamia inferen female moths to lay eggs on the trap crops; putting the sex attractant in the ice field (zizania aquatica field), the sex attractant being put in a trap device to trap sesamia inferen male insects; parallel distance between the sesamia inferen sex attractant and the trap crop being 10-15 m. The trap crops and the sex attractant are used in a combined manner in a specific method. The method substantially improves trapping effect of vetiver grass on sesamia inferen female insects and trapping effect of the sex attractant on the sesamia inferen male insects, reduces population quantity of sesamia inferen adults in the rice field (zizania aquatica field) and field population quantity of next generation larva, and improves seedling protection effect on rice (zizania aquatica).

Description

technical field [0001] The invention relates to the technical field of ecological control of agricultural pests, in particular to a method for coordinated control of stem borers by using lure plants and sex attractants. In particular, the invention relates to a method for controlling the rice or wild rice stem borer pest, the rice stem borer, through the coordinated application of the insect-attracting plant vetiver and the sex-attractant of the rice stem borer. Background technique [0002] In recent years, due to the adjustment of planting structure, change of farming system, variety replacement, climate change and increase of pesticide resistance, the population of Sesamia inferens, a major rice pest, has shown a sharp increase. 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, seriou...

AI Technical Summary

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

Most borers are borer pests, causing hidden damage. 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.

Moreover, since the chemicals directly enter the water, they will have a negative impact on the aquatic ecosystem and its organisms.
