人类的发展面临着许多问题,其中包括环境污染与害虫暴发失控等,对策应是人类谋求与自然协调共存。人类必须学会既要和众多的非生命物又要和亿万种生物,包括成百万上千万种昆虫协调共存。 地球上约有100多万种昆虫,有害的昆虫有8万余种,但真正造成危害的仅3000余种,在一个地区严重有危害的也只有几十种。我国约有15万种昆虫,其中仅有少数是农林牧医方面的害虫;少数如家蚕、蜜蜂、紫胶虫、倍蚜、食品昆虫、药用昆虫及害虫的天敌是益虫;绝大多数是益害不显著的。近半个多世纪以来在人类防治害虫的历史中,单纯使用化学农药造成了许多不良后果:许多害虫对化学农药产

A few natural enemies such as silkworm, bee, lac insect, double aphid, food insects, medicinal insects and pests are beneficial insects; Benefit is not significant. Nearly half a century in the history of human pest control, the use of chemical pesticides alone has caused many adverse consequences: many pests on the chemical pesticide production
