【摘要】 花绒寄甲Dastarcus helophoroides是大型天牛的主要天敌昆虫。通过野外调查与室内观察相结合,补充研究了花绒寄甲在我国的分布、栖境特点,以及与其分布相关的耐高温、耐低温、耐饥能力等参数。在此基础上,对花绒寄甲控制天牛类害虫的利用前景及作为天敌昆虫输出国外的可行性作了探讨。更多还原

【Abstract】 Dastarcus helophoroides was an important insect natural enemy of large-body longhorned beetles.The distribution and habitat about this natural enemy were surveyed around China and its rela-ted ecological biology was studied.Studies showed that D.helophoroides distributed in many pro-vinces in China.It had high hungry endurance ability and 50% of the adults could live over 60 days without food and water supply.The survival rate of adults at(35±0.5) ℃ and(-10±4) ℃ was studied respectively too.Base on these studies,the prospects of using D.helophoroides against longhorned beetles and exporting it abroad as insect natural enemy in future were discussed.更多还原
