摘要:

采用室内试验与室外观察相结合的方法研究云斑天牛的交配及产卵行为。结果表明:云斑天牛一次完整的交配过程包括相遇抱对、插入输精和配后保护3个阶段。在交配过程中雄虫有多次插入输精现象,一次完整的交配过程平均需要17.81 min。其中,输精前抱对平均时间为2.16 min,总输精时间平均为10.28 min,交配过程中每次插入输精时间平均为23.4 s,配后保护时间为5.37 min。野外交配行为与室内试验结果一致。云斑天牛雌、雄个体交配次数差异很大,而且寄主植物对云斑天牛聚集和交配有明显影响。不同补充营养寄主对产卵量的影响试验中,云斑天牛取食光皮桦和法国冬青的枝皮面积(572.47,370.83 mm2)以及取食后的平均每天每头产卵量(2.44和1.80粒)最大,显著高于杨树、核桃和旱柳(P<0.05)。对产卵诱木的选择试验中,在杨树和核桃木段上的产卵量最大。羽化出孔后单独饲养8天的云斑天牛在第10到14天之间达到产卵高峰期。

Abstract:

In this paper, mating and oviposition behavior of Batocera horsfieldi were investigated by laboratory tests combined with the field observation. The results were as follows: A complete copulation process of B. horsfieldi included encountering pair-bonding, ejaculations, as well as post-copulatory guarding. A complete mating of B. horsfieldi involved three stages, i.e. encountering pair-bonding, ejaculation and post-copulatory guarding. There were many insertions in the whole mating process.The average duration time for single copulation was 17.81 min, including average time of 2.16 min for pair-bonding before ejaculation, average time of 10.28 min for total ejaculation, duration of 23.4 s for single ejaculation and the time of 5.37 min for post-copulatory guarding. B. horsfieldi's field mating behaviours were consistent with that of the laboratory experiments. The times of matings for the female B. horsfieldi were greatly different from the male ones. Moreover, the host plants had a great influence on the gathering and the copulation of B. horsfieldi. A test of influence of 5 species of host plants on the spawn showed that B. horsfieldi took the most food from bark of branches of Betula luminifera and Viburnum awabuki (572.47 mm2 and 370.83 mm2) and spawned (2.44 and 1.80) the most with the food, much more than that fed from Populus sp., Juglans regia and Salix matsudana (P<0.05). In a tested for choosing the spawning tempting plants, B. horsfieldi spawned the most on the bottom boards of Populus sp. and Juglans regia. After emergence, B. horsfieldi, raised alone for 8 days, could have their spawning peak between the 10th day and the 14th day.
