【摘要】 [目的]调查保定市郊土蝗的优势种并提出防治方法。[方法]2005~2006年9月在保定市郊通过网捕的方法,记载田间蝗虫的种类和数量,对不能确定的种类,借助体视显微镜进行观察、描述和鉴定,并归纳其发生规律,提出防治方法。[结果]除东亚飞蝗和稻蝗外,土蝗主要有7个优势种,即短星翅蝗、长翅素木蝗、短额负蝗、中华剑角蝗、大垫尖翅蝗、花胫绿纹蝗和黄胫小车蝗。土蝗的食物范围广,以卵块在土中越冬。可采用耕翻土地,修埂培土,灭草开荒等农事操作压低虫口密度,结合药剂喷雾或毒饵诱杀防治。[结论]该研究为保定市郊土蝗的有效防治奠定了基础。更多还原

【Abstract】 [Objective] The aim was to investigate the dominant species of locust at the suburb of Baoding and put forward the control methods.[Method] The species and quantities of the field locust were recorded by net catching at the suburb of Baoding in September of 2005-2006.The uncertain species were observed,described and identified by stereomicroscope.The occurrence law of locust was concluded and the controlling measures were put forward.[Result] Expect Locutsa migratoria and Oxya chinensis,locust had mainly 7 dominant species,that was Calliptamus abbreviatus,Shirakiacris shirakii,Atractomorpha sinensis,Acrida cinerea,Epacromius coerulipes,Aiolopus tamulus and Oedaleus infernalis.The food scope of locust was wide and they overwintered in the soil in the form of egg.Some farming operations such as ploughing soil,repairing dam and molding,and weed-killing and land-breaking could be applied to decrease the pest density and reagent spaying or toxic bait trapping could be combined to control.[Conclusion] The research laid the foundation for the effective control of locust at the suburb of Baoding.更多还原
