江苏盐城农区棉盲蝽监控新技术的研究进展

通过对当地棉花重大的致灾害虫棉盲蝽进行了历时17年的研究，取得显著进展，主要包括11个专题：（1）明确了盐城农区棉盲蝽40多年的演变过程，（2）明确了棉盲蝽新近的暴发机制，（3）明确了多种因子对棉盲蝽种群形成与发展的干扰作用，（4）明确了盐城农区棉盲蝽的生物生态学特性，（5）明确了近年两种棉盲蝽优势种群比例变化的原因，（6）明确了棉盲蝽对不同长势Bt棉幼铃的危害特点，（7）明确了棉田天敌种群的消长与保护利用措施，（8）研制了Bt棉田棉盲蝽防治指标，优化了棉盲蝽防治对策，（9）明确了两种棉盲蝽的转移规律与虫源性质，（10）改进并提高了棉盲蝽测报预警的准确率，（11）在两种棉盲蝽的多食性特点研究方面：一是明确了棉盲蝽在当地的寄主范围、生态区划及发育和产卵趋性，二是明确了两种棉盲蝽寄主适合度及其表达的影响因素，三是明确了两种棉盲蝽的区域性生态分布。

Study Progress of New Monitoring Technology on Cotton Fleahoppers in Yancheng Agricultural Area in Jiangsu Province

The cotton fleahoppers in local cotton field were studied for 17 years,and many progresses were obtained.The main 11 progresses were as follow:(1) the evolvement process of cotton fleahoppers was definite in Yancheng agricultural area;(2) the recent outbreak mechanism was definite in Yancheng agricultural area;(3) the interference action of various factors on the formation and population were definite;(4) the biological and ecological characteristics of fleahoppers were definite in Yancheng agricultural area;(5) the reason why the population of fleahoppers changed was studied;(6) the feature of injured young cotton by fleahoppers was studied;(7) the measures of protecting the natural enemies in cotton field were studied;(8) the control index was studied and improved;(9) the rule and pest properties of 2 cotton fleahoppers were studied;(10) the accuracy of forecast of fleahopper was improved;(11) the polyphagy of 2 fleahoppers was studied,and the range of host plants,ecological division and laying taxis were definite,the fitness and express's influential factors were studied,the regional ecological distribution was definite.
