Method for protecting and using spiders to prevent and treat rice pests

Abstract

The invention discloses a method for protecting and using spiders to prevent and treat rice pests. The method comprises the steps of (1) planting a spider shelter, wherein herba cepbalanoplosis segeti and sonchus brachyotus are planted on ridges of a rice field, the planting width is 35-45 centimeters, and a shelter zone is formed so that spiders can have a migration place after harvest of the rice field is completed; (2) trapping the spiders, wherein after wheat in the rice field is harvested, rice straws, the herba cepbalanoplosis segeti and the sonchus brachyotus are tied up into cone-shaped trapping heaps, ten trapping heaps are used in per mu of the rice field and are evenly distributed in the rice field, the rice field is irrigated, the spiders enter the trapping heaps, and after 12 hours, the trapping heaps in the rice field are collected; (3) assisting the spiders in migrating, wherein the collected trapping heaps in thestep (2) are evenly placed on the shelter zone in the step (1) and are broken up, so that the spiders on the trapping heaps enter the shelter zone in the step (1); (4) spider migrating; wherein field pest generation conditions are investigated periodically after rice is transplanted, when the delphacidae number in the field reaches 300-500 heads per hundred caves, the shelter zone in the step (1) is destroyed, and the spiders are compelled to migrate to the rice field.

Description

technical field [0001] The invention belongs to the field of biological control of rice pests, in particular to a method for protecting and utilizing spiders to prevent and control rice pests. Background technique [0002] Rice is one of the most important food crops in my country. In recent years, people have paid more and more attention to the quality and safety of rice. One-sided pursuit of high yield is no longer the main goal of current agricultural production. How to reduce the use of chemical pesticides and improve rice quality is the current agricultural production. most important issue. At present, the control of diseases and insect pests in the rice production process mainly depends on the control of chemical pesticides. The use of a large number of pesticides greatly reduces the quality of rice, damages the ecological environment, and poses a serious threat to human and animal health. [0003] Spiders are the most diverse and numerous arthropods in rice fields a...
