正确说法

• 生物防治法利用害虫的天敌来控制虫害，既有效又能减少化学农药对环境的污染。(Biological control methods use natural enemies of pests to manage infestations, which is both effective and reduces chemical pesticide pollution.)
• 仓库中的储粮遭受害虫侵袭，损失惨重，管理部门随即启动了紧急防治预案。(Stored grain in the warehouse was severely damaged by pests, resulting in heavy losses, and management immediately activated an emergency pest control plan.)

错误说法

• 将所有昆虫称为害虫 — 害虫 only applies to harmful species; beneficial insects like 蜜蜂 (bees) and 蚕 (silkworms) must never be called 害虫
