竹广肩小蜂和竹瘿长尾小蜂是竹瘿小蜂的优势种。研究表明竹广肩小蜂每年 1代 ,以蛹在虫瘿内越冬 ;成虫在 3月下旬至 4月下旬出瘿 ;幼虫 5龄 ,发生期在 4月上旬至 9月中旬。竹长尾小蜂每年 1代 ,以幼虫在虫瘿内越冬 ;成虫于 4月中旬至 5月上旬羽化出瘿 ,产卵于已被竹广肩小蜂产卵的芽中 ;幼虫孵化后占据竹广肩小蜂的虫瘿 ,幼龄时可食竹广肩小蜂幼虫尸体 ;幼虫 5龄 ,发生期有 5月上旬至次年 3月下旬 ,9月后渐入老熟越冬。对这 2种小蜂的卵形态和各虫态生活习性也作了观察研究。表 1参 3
Bamboo wide-shouldered wasp and Penny’s long-tailed wasp is the dominant species of Penny’s bee. Studies have shown that the broad-bearded Shibei Shigu per year a generation, the pupa in the wintering winter; adults in late March to late April out of a larvae; larvae 5th instars, occurred in early April to mid-September. Long-tailed Bumblebee per generation a year, the larvae wintering in the insects; adults in mid-April to early May feather out of the 产, spawning in the spatula has been spawned eggs; Bud larvae occupy after hatching Zhu Guang Shuanghuan beetle nectar, juvenile edible bamboo broadleaf larvae parasites; larvae 5th instar, the occurrence of early May to the end of March next year, after September gradually mature winter. The oviposition and life habits of these two kinds of small bees were also observed and studied. Table 1 reference 3
