摘　　要：在室内进行桑天牛成虫饲养,并对其取食、交配、产卵、刻槽等行为进行了观察研究。结果表明:桑天牛成虫在同一构树枝上取食时有部位选择行为,其先试探选择2～5个部位,选定后连续取食;雌虫的日取食量明显大于雄虫;成虫求偶交配行为分为求偶、抱对、交配、拆对等阶段;雌成虫刻槽产卵是一个完整的过程,可明显区分为位置选择、咬槽、产卵、封槽4个阶段。成虫取食高峰期为6:00—8:00,次高峰期为12:00—14:00,上午取食量占日取食量的一半以上;求偶时间可达78～148 s,平均约119.56 s;每次交配的持续时间为312～605 s,平均约445.62 s;雌成虫咬刻槽的时间为15～25 min,每产1粒卵的时间为3～5 min;桑天牛成虫在1 d内产卵最多的时间段是20:00—22:00,约占日产卵量的1/3;产卵量随着时间的推移逐渐减少;雌成虫交配后可持续产卵1个月以上。The author observed feeding behaviors,mating,oviposition,gnawing incision of Apriona germari adults by indoors rearing.Results showed that these adults tried to feed on 2 to 5 parts of one branch of Broussonetia papyrifera,and then chose one to continue feeding.Females ingest more food than males in a day.Adults＇ mating behaviors is comprised of several stages such as courtship,precopulatory mounting,mating,postcoital separate.Ovipositing incision of adults was a whole process that could be divided into four phases such as site selection,incision,ovipositing,seal.The fastigium of adults＇ feeding was from 6：00 to 8：00am,and the second peak appeared from 12：00 to 14：00 pm.The feeding weight of the two above-stages occupied half of whole feeding weight in one day.Male adults＇ courtship could last 78-148 s,average 119.56 s.Mating could last 312-605 s,average 445.62 s.Gnawing incision and oviposition of female could last 15-25 min and 3-5 min,respectively.The time of maximum oviposition was from 20：00-22：00 pm.And the quantity of maximum oviposition could account for a third of total oviposition amount in a day.The quantity of oviposition decreased as time passing.Females＇ oviposition behavior could sustain for one month at least.
