This standard specifies control techniques for rice water weevil, including terms and definitions, general principles, control measures, and pest density testing methods. Control measures encompass plant quarantine, agricultural control, and chemical control, with chemical control as the primary method. The standard defines the control index (0.3 adults per hill or 10 per square meter) and the suitable period for control, guiding pesticide application before transplanting and during adult migration peaks. It applies to all rice water weevil occurrence areas nationwide, aiming to control the pest safely, economically, and effectively to protect rice production.
本标准规定了稻水象甲的防治技术，包括术语定义、总则、防治措施和虫口密度测试方法。防治措施涵盖植物检疫、农业防治和化学防治，其中化学防治为主。标准明确了防治指标（成虫0.3头/丛或10头/平方米）和防治适期，指导在秧苗移栽前及成虫迁入高峰期施药。该标准适用于全国稻水象甲发生区，旨在安全、经济、有效地控制虫害，保障水稻生产。

This standard specifies the terms and definitions, general principles, control measures, and pest density testing methods for the control of rice water weevil (Lissorhobtrus oryzobhilus Kuschel).
The control index, also known as the economic threshold or control threshold, is the pest density at the suitable period for control at which control measures should be taken to prevent damage losses from exceeding the economic injury level.
Implement plant quarantine measures to control the spread and蔓延 of rice water weevil; in rice areas where the pest has already occurred and is difficult to eradicate, adopt measures combining agricultural control and chemical control, with chemical control as the main method, following the principle of 'safe, economical, and effective'.
Adult insect density: 0.3 per hill or 10 per square meter.
Apply pesticide in the seedling bed 1 to 2 days before transplanting rice seedlings, so that the seedlings carry the pesticide into the field; apply pesticide once when adult rice water weevils migrating from overwintering sites into the rice field or direct-seeded field reach the control index; if the density of subsequently migrating adult rice water weevils again reaches the control index, then...
