胡萝卜微管蚜为山银花主要为害害虫之一，为探究该害虫若虫越冬情况，于2021年11月至2024年3月选择3个冬季时间段，在重庆市秀山县8个灰毡毛忍冬‘渝蕾1号’种植基地开展定点观测，利用肉眼普遍查看与翻叶抽查相结合的方式观察其若虫和成虫虫态、数量和越冬场所，以及若虫活动性；并对其间的月最低温进行统计，分析其越冬期。结果表明，在冬季阶段，基地1~5的胡萝卜微管蚜均能以若虫虫态存活；2022年2月下旬，基地1和基地2的若虫虫量分别为3、1头/叶；2023年2月下旬，基地3、基地4和基地5的若虫虫量分别为4、2和2头/叶；基地6、基地7和基地8其若虫在灰毡毛忍冬叶片背面、正面、枝和嫩芽的越冬比例分别在87.4%~89.3%，1.5%~2.7%，1.4%~1.6%，7.2%~8.4%；在冬季气温0 ℃以下时，若虫能以休眠或静伏等状态越冬，在一定温度范围内，若虫活动性随温度升高而增强；8个基地11月的最低气温均在0 ℃以上；12月至次年2月的最低气温均在0 ℃以下。综合表明，山银花胡萝卜微管蚜能以若虫虫态越冬，越冬场所以叶片背面为主，越冬期为12月至次年2月。本研究为胡萝卜微管蚜的预测和绿色防控提供参考。

Semiaphis heraclei is one of the major pests infesting Lonicera macranthoides. To investigate the overwintering status of its nymphs, fixed-point observations were conducted at 8 planting bases of L. macranthoides ‘Yulei No.1’ in Xiushan County, Chongqing, across 3 winter periods from November 2021 to March 2024. A combination of general visual inspection and leaf-turning spot checks was used to observe the nymphal and adult morphologies, population densities, overwintering sites, and nymphal activity. Additionally, the monthly minimum temperatures during the period were recorded to analyze the overwintering stage. The results showed that S. heraclei nymphs survived through the winter at bases 1-5. In the late February of 2022, the nymph density was recorded as 3 individuals per leaf in base 1 and 1 individual per leaf in base 2, respectively. In the late February of 2023, the nymph density in base 3, base 4 and base 5 reached 4 individuals per leaf, 2 individuals per leaf and 2 individuals per leaf, respectively. At bases 6-8, the overwintering proportions of nymphs on the abaxial surface, adaxial surface, branches, and tender shoots of L. macranthoides were 87.4%-89.3%, 1.5%-2.7%, 1.4%-1.6%, and 7.2%-8.4%, respectively. When the winter temperature dropped below 0 °C, nymphs overwintered in a dormant or quiescent state; within a certain temperature range, nymphal activity increased with rising temperatures. The average minimum temperature in November was above 0 °C at all 8 bases, while the minimum temperature from December to February of the following year was below 0 °C. Collectively, the findings indicate that S. heraclei on L. macranthoides overwinters as nymphs, with the abaxial leaf surface as the primary overwintering site, and the overwintering period lasts from December to February of the next year. This study provides a reference for the prediction and green control of S. heraclei.
