| 通过野外调查和室内饲养对发生在云南保山余甘子Phyllanthus emblica Linn.植株上的桔斑簇天牛Aristobia approximator（Thomson）形态特征和生物学特性进行研究。结果表明，桔斑簇天牛1年发生1代，以卵和1~3龄幼虫在产卵槽底部和蛀食坑道内越冬。越冬期大龄幼虫于翌年3月下旬化蛹，低龄幼虫于5月下旬化蛹，蛹平均历期65~78d。6月上旬至10月上旬为成虫羽化期，6月下旬至8月中旬为羽化高峰期，成虫平均寿命为38~47d。7月上旬至10月上旬为产卵期，树皮厚度为3~5mm之间的产卵量最多，产卵率为96.03%。7月中旬至11月下旬为卵孵化期，卵孵化率为91.80%，卵的平均历期18~25d。10月中旬卵和幼虫进入越冬，10月中旬至11月下旬平均气温在10~15℃时越冬卵孵化率下降为57.30%。越冬期幼虫处于持续蛀食发育状态，幼虫平均历期为225~240d，幼虫大致分为6龄，4~5龄幼虫取食量最大，平均单日蛀道容积为28.26cm3。 |
| 英文摘要: |
| Through the field investigation and the indoor breeding, we studied the morphological and biological characteristics of Aristobia approximator growing in Phyllanthus emblica in Baoshan, Yunnan. The results showed that there was one generation of Aristobia approximator in a year, and their eggs and 1st-3rd instars larvae overwintered in the bottom of the ovipositing incision and the tunnel. The older overwintering larvae pupated in late March of the following year, and the younger larvae pupated in late May. The average pupa duration was 65~78 d. The adult eclosion period was from early June to early October, and the peak period was from late June to mid-August. The average life span of the adult was 38~47 d. The spawning period was from early July to early October, and the most spawning occurred in 3~5 mm of the bark. The spawning rate was 96.03%. The incubation period was from mid-July to late November,The hatching rate of eggs was 91.80%, and the average egg duration is 18~25 d. The eggs and larvae started to overwinter in the middle of October, and the average incubation rate of the overwintering eggs was 57.30% when the average temperature was 10~15℃ from mid-October to late November. The larvae could keep eating and growing in the overwintering stage. and the average larva duration was 225~240 d, The larvae have six instars, the food intake of the 4th-5th instars larvae was the highest, and their average daily cubage of the wormholes was 28.26 cm3. |
