自从高效杀虫剂广泛使用后,屡屡出现食用果蔬人畜中毒和死亡事件。科学家追踪调查显示,高分子合成农药残余物已对野生动物乃至海洋生物都构成了潜在的毒害作用,并导致繁殖力下降。有鉴于此,美国农业部率先明令禁止使用包括DDT在内的多种农药,并转向大力开发生物工程技术为主的抗病毒、抗病虫害农作物新品种,迄今已是硕果累累前景看好。与此同时,科学家发现以虫治虫效果更好,且有益保持自然生态平衡和物种多样化良性发展。其中捕虫 Since the widespread use of highly effective insecticides, the frequent occurrence of food poisoning and death of fruits and vegetables. Scientists follow-up survey showed that polymer synthetic pesticide residues have posed a potential poisoning effect on wildlife and even marine life, leading to a decline in fertility. In view of this, the USDA took the lead to prohibit the use of multiple pesticides including DDT and turned to vigorously develop new varieties of antiviral, pest-resistant crops that are mainly based on bioengineering technology. So far the fruitful prospect is promising. In the meantime, scientists have found that insect pest control is better, and beneficial to maintain the natural ecological balance and the healthy development of species diversity. Which insects
