棉蚜是棉花的重要害虫之一,在新疆每隔4~5年暴发一次,导致当地棉花减产10%~20%。害虫主要依靠化学防治,不但使每亩棉田增加了40~60元的生产成本,而且削弱了自然天敌对害虫的控制能力。众所周知,农药长期大量使用也直接威胁着环境健康和生态系统服务。中国科学院新疆生态与地理研究所研究员吕昭智及其研究团队与澳大利亚昆士兰大学的研究人员于2004 Cotton aphid is one of the important pests of cotton. Once in every 4 to 5 years, cotton aphid outbreak once caused 10% -20% loss of local cotton. Pest mainly rely on chemical control, not only increased per mu of cotton fields 40 to 60 yuan of production costs, but also weakened the control of natural enemies of pests. It is well-known that long-term heavy use of pesticides also directly threatens environmental health and ecosystem services.
