摘要

最近在泰国发现了一种新的寄主植物肉桂(Cinnamomum spp.)。比较了肉桂在自然野外、半自然笼养和实验室条件下的生活史和行为,以及从猪李(Spondias pinnata)中机会采集的结果。实验室饲养通过延迟卵期和蛹期显著延长了蛹的发育时间(62.30±3.68 d),显著高于野外饲养(56.30±1.83 d, p < 0.001),表明了生活史的可塑性。我们发现了密度依赖性的产卵可塑性(野外线性排列:155.6±84.9个卵/批;实验室聚集)和新颖的群居结茧行为,其中85.1%的个体(n = 47个站点)聚集形成具有独特网状结构的公共群集。实验室条件下的雌茧壳比(5.02±0.72%)和猪李组(5.30±0.30%)显著高于田间条件(3.92±0.51%,p = 0.002)。机会饲养可产新鲜茧20公斤,每丛可达0.220公斤。这些发现建立了三氟家蚕对肉桂的生物学基础,揭示了鳞翅目复杂的社会行为,扩展了鳞翅目的社会性概念,并展示了可持续蚕桑与害虫管理相结合的商业潜力。

Life History Plasticity and Gregarious Cocooning Behavior of the Wild Silkmoth Cricula trifenestrata Helfer (Lepidoptera: Saturniidae) on a Novel Host Plant, Cinnamon, in Thailand.

Cricula trifenestrata Helfer was recently documented on cinnamon (Cinnamomum spp.), a novel host plant in Thailand. We compared life history and behavior under natural field, semi-natural caged, and laboratory conditions on cinnamon, plus opportunistic collection from hog plum (Spondias pinnata). Laboratory rearing significantly extended development (62.30 ± 3.68 days) versus field conditions (56.30 ± 1.83 days, p < 0.001) through delayed egg and pupal stages, indicating life history plasticity. We discovered density-dependent oviposition plasticity (linear arrangements in field: 155.6 ± 84.9 eggs/batch; clustered in laboratory) and novel gregarious cocooning behavior, where 85.1% of individuals (n = 47 sites) aggregated to form communal clusters with unique reticulated architecture. Female cocoon shell ratio (CSR) was significantly higher in laboratory (5.02 ± 0.72%) and hog plum cohorts (5.30 ± 0.30%) than field conditions (3.92 ± 0.51%, p = 0.002). Opportunistic rearing yielded >2 kg fresh cocoons, with clusters reaching 0.220 kg. These findings establish biological baselines for C. trifenestrata Helfer on cinnamon, reveal sophisticated social behaviors expanding lepidopteran sociality concepts, and demonstrate commercial potential for sustainable sericulture integrated with pest management.

期刊介绍: Insects (ISSN 2075-4450) is an international, peer-reviewed open access journal of entomology published by MDPI online quarterly. It publishes reviews, research papers and communications related to the biology, physiology and the behavior of insects and arthropods. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
