Global warming significantly impacts pest control, making it a more complex challenge. Here are some key points:
Increased pest activity: Warmer temperatures can extend the geographical range and active seasons of many pests. This means pests that were once confined to certain areas are now spreading to new regions.
Higher crop damage: Climate change make pests more destructive. For example, the fall armyworm, which feeds on crops like maize and sorghum, has spread due to warmer climate, causing significant agricultural damage.
Pesticide effectiveness: The effectiveness of pesticides can be reduced under changing environment conditions. This necessitates more frequent applications and the development of new pest management strategies.
Food security threats: Increased pest activity and crop damage threaten global food security. Smallholder farmers and regions already facing food security issues are particularly at risk.
Environment impact: The increased use of pesticides to combat more resilient pests can lead to environmental pollution, affecting biodiversity and ecosystem health.
Addressing these challenges requires international cooperation, improved pest management practices, and more research into sustainable solutions.

全球暖化顯著影響害蟲防治,使其成為更複雜的挑戰。以下是一些重點:
害蟲活動增加: 溫度升高會擴大許多害蟲的地理範圍和活躍季節。這意味著曾經局限於某些地區的害蟲現在擴散到新的地區。
農作物損害增加: 氣候變遷使害蟲更具破壞性。舉例來說,以玉米和高粱等作物為食的秋蟬,因氣候變暖而擴散,造成嚴重的農業損害。
殺蟲劑的效力: 在不斷變化的環境條件下,殺蟲劑的效力可能會降低。這就需要更頻繁地施用殺蟲劑,並開發新的害蟲管理策略。
食品保障威脅: 害蟲活動和作物損害的增加會威脅全球糧食保障。已經面臨糧食保障問題的小農戶和地區尤其受到威脅。
環境影響: 增加使用殺蟲劑來對付適應能力強的的害蟲,會造成環境污染,影響生物多樣性和生態系統健康。
應對這些挑戰需要國際合作、改進害蟲管理方法,以及更多可持續解決方案的研究。
