摘要
食木蟑螂Panesthia angustipennis spadica Shiraki (Blaberidae)生活在腐朽原木的隧道中,被认为是群居物种。然而,腐烂的原木在森林中以丛状分布,腐烂的原木中的木质隧道为若虫提供了一个半封闭的环境。我们进行了实验室实验,以确定spadica P. angustipennis spadica的一、二龄若虫是否在木质隧道等小空间中表现出群居性。我们还比较了兄弟群体和混合群体在二龄时的聚集强度。实验表明,无论亲缘关系如何,一龄和二龄若虫都表现出群居性,在聚集行为上没有差异。这些结果表明,非亲属为基础的群居性可能有助于维持一个领域中包含来自多个家庭的个体的spagustipenis spadica菌落。
Aggregation behaviors of young nymphs in Panesthia angustipennis spadica (Blaberidae)
The wood-feeding cockroach Panesthia angustipennis spadica Shiraki (Blaberidae) lives in a tunnel of decayed logs and is considered as gregarious species. However, decayed logs are distributed in a forest in clumps, and woody tunnels in decaying logs provide a semi-enclosed environment for nymphs. We performed laboratory experiments to determine whether first- and second-instar nymphs of P. angustipennis spadica show gregariousness in small spaces like woody tunnels. We also compared the aggregation intensity of sibling groups and mixed groups in the second instar. The laboratory experiments demonstrated that both the first- and second-instar nymphs show gregariousness, with no difference in aggregation behavior regardless of kin relatedness. These results suggest that non-kin-based gregariousness may help to maintain colonies of P. angustipennis spadica that contain individuals derived from multiple families in a field.
期刊介绍:
Entomological Science is the official English language journal of the Entomological Society of Japan. The Journal publishes original research papers and reviews from any entomological discipline or from directly allied field in ecology, behavioral biology, physiology, biochemistry, development, genetics, systematics, morphology, evolution and general entomology. Papers of applied entomology will be considered for publication if they significantly advance in the field of entomological science in the opinion of the Editors and Editorial Board.
