| 【目的】明确茶翅蝽Halyomorpha halys (St?l)各龄期个体发育过程中的形态特征变化规律，系统阐述其完整生活史及成虫主要生活习性，探究形态特征变化与环境压力的联系，为该害虫的防控及相关类群发育形态学研究提供依据。【方法】本文在室内控温条件下（温度25℃、相对湿度（70 ± 5）%、光周期16 L∶8 D），以野外采集的成虫建立试验种群，使用特制饲养盒集群饲养。通过体式显微成像系统观察并记录卵、各龄若虫及成虫的形态特征，详细追踪观察茶翅蝽的产卵、孵化、蜕皮、生长等发育过程。【结果】详细描述了茶翅蝽从卵到成虫各阶段的形态特征。卵块多呈不规则排列，单卵具假卵盖，孵化前出现三角形破卵器的特征。测定了1~5龄若虫体长及各龄发育历期。详细描述了各龄若虫在体色、刺突、毛点毛及腹背斑纹等关键形态上的动态演变规律，并明确成虫雌雄体长存在差异。观察记录了成虫特定的取食、交配与产卵行为，发现一次产卵量多为28粒左右。研究明确了如后胸臭腺的出现、腹臭腺的闭合等关键形态变化节点。【结论】茶翅蝽在个体发育过程中，其形态特征的阶段性变化反映了对环境适应的响应。本研究系统提供了该虫生活史及各龄期形态的详细资料，为理解其适应机制和进化过程提供了形态学依据。 |

| 【Aim】To clarify the ontogenetic morphological variations of Halyomorpha halys across all instars, document its complete life history and primary adult behaviors, and explore the correlations between these morphological changes and environmental pressures, thereby providing a basis for pest management and developmental morphology research in related taxa.【Methods】Under controlled laboratory conditions (25 °C, (70 ± 5)% RH, 16 L∶8 D photoperiod), an experimental colony established from field-collected adults was group-reared in specially designed containers. Morphological characteristics of eggs, all nymphal instars, and adults were observed and documented using a stereomicroscope imaging system. Key developmental processes including oviposition, hatching, molting, and growth were monitored in detail.【Results】Morphological characteristics for each developmental stage were described in detail. Egg masses were predominantly irregularly arranged; individual eggs possessed a false operculum, with a triangular egg burster evident prior to hatching. Body lengths and developmental durations were measured for all nymphal instars. Dynamic ontogenetic changes in key morphological traits—including body coloration, protuberances, trichobothria, and dorsal markings—were characterized. Sexual dimorphism in adult body length was confirmed. Specific adult behaviors (feeding, mating, oviposition) were documented, with a common oviposition of approximately 28 eggs per mass. Critical morphological transition nodes were identified, such as the development of the metathoracic scent glands and the closure of the abdominal scent glands.【Conclusion】The stage-specific morphological changes during the ontogeny of H. halys reflect adaptive responses to environmental conditions. This study provides comprehensive data on its life history and instar-specific morphology, offering essential morphological evidence for understanding the species' adaptive mechanisms and evolutionary processes. |
