摘要：用自行设计的昆虫行为观测箱,研究花绒寄甲成虫的日活动节律、趋光性、交配行为以及黑暗对成虫活动的影响。结果发现成虫多在黄昏至第2天上午活动,其活动节律可被连续的黑暗处理所打破,交尾形式呈"—"字形,有较弱的趋弱红光性;并应用石蜡包埋的方法,研究花绒寄甲成虫的视觉在寻找寄主幼虫时的作用,发现在弱红光的条件下,其视觉对寻找寄主幼虫作用不大;同时,在成虫的活动高峰期,采用模拟自然界其生活习性释放成虫的方法,研究花绒寄甲成虫的活动能力,发现成虫的活动、飞翔能力较强。研究结果为在室内繁殖及野外释放防治天牛类害虫打下基础。
Dastarcus helophoroides （Coleoptera： Bothrideridae） an important cerambycid parasitoid beetle, can parasitize larva, pupa of many large-sized longhorn beetles, suchas Asian Longhorned Beetle, in China. In order to make better use of this parasitoid to biologically control the pest longhorn beetles, the behavior of D. helophoroides was studied in this paper, with a self-designed observation box, we studied the daily behavioral rhythm of D. helophoroides adult, and their photokinesis, mating behavior,as well as their behavioral rhythm influenced by darkness. Results showed that adults were active from dusk to next morning,and their behavioral rhythm could be disturbed by long period of darkness. Adults had slight tropism to wards dim red light. Mating posture of female and male adults displayed a ＂--＂ shape. The vision was not used for the adults to find their host larvae of longhorned beetle wrapped with paraffin under dim red light. The result showed that the vision of the parasitoid was not able to differentiate larva of longhorned beetle from wood. During the most active period of the most active period of the adult, by imitating natural action character of the parasitoid, its disperse capability was investigated. It was found that adults of D. helophoroides have strong fly ability. These results would be helpful to develop techniques for mass-rearing D. helophoroides indoor and releasing them out to control longhorned beetles.
