摘  要  【目的】 为明确山西省太谷区番茄潜叶蛾Tuta absoluta的发生动态及幼虫和卵的空间分布，筛选出粘虫板与性诱剂最佳防治组合及使用方法。【方法】 于2023年6月26日至11月20日将不同颜色粘虫板和性诱芯组合，以不同高度悬挂于温室大棚内，调查番茄潜叶蛾的发生动态，筛选最佳防治组合及悬挂高度；用“W”形取样法调查幼虫和卵在番茄植株上的空间分布。【结果】 8月28日至9月4日[（404±8.63）头/7 d]和10月9日至16日[（373±13.28）头/7 d]两个时间段为番茄潜叶蛾发生高峰期。粘虫板和性诱芯组合试验表明，当其放置高度为0-25 cm时防治效果最佳，诱捕量达（133±6.56）头/7 d；不同颜色粘虫板和性诱芯组合对番茄潜叶蛾防治效果差异显著（P<0.05），其中红色粘虫板组合诱捕量最多[（1 017±39.12）头/7 d]，白色板组合最少[（80±9.49）头/7 d]。番茄潜叶蛾的幼虫和卵在前期主要分布在温室大棚入口处，随着番茄受害加重，逐渐向温室内部转移，幼虫和卵在大棚边缘通风处分布较多，在中间过道处最少；幼虫由番茄植株下部逐渐向中上部转移，而卵一直分布在植株中上部。【结论】 应在大棚两侧通风处及入口处加强管理，可使用红色粘虫板和性诱芯组合，将其悬挂在靠近地面的地方，以有效防控番茄潜叶蛾。

Abstract  [Aim]  To clarify the population dynamics and spatial distribution of the larvae and eggs of Tuta absoluta in the Taigu Region, Shanxi Province, and to optimize the use of sticky insect plates and sex pheromone lures to control this pest. [Methods]  Different combinations of pheromone traps and sticky insect plates were hung at different heights in a greenhouse and the number of insects captured in each trap was compared. In addition, the spatial distribution of larvae and eggs on tomato plants was investigated using the "W" shaped sampling method. [Results]  The occurrence of T. absoluta was highest from August 28 to September 4 [(404±8.63) ind./7 d] and from October 9 to 16 [(373±13.28) ind./7 d]. Traps hung at a height of 0-25 cm captured the most adult T. absoluta; up to (133±6.56) ind. over 7 days. The color of the sticky plate used had a significant effect on the number of T. absoluta captured; traps used in combination with red sticky plates captured the most  [ (1 017±39.12) ind./7 d] and those with white sticky plates the least [(80±9.49) ind./7 d]. Larvae and eggs were mainly found at the entrance of the greenhouse in the initial stage of infestation, gradually moving further inside the greenhouse as tomato damage increased. Larvae and eggs were more widely distributed in ventilated areas at the edge of the greenhouse and less common in the central aisle. Larvae gradually moved from the lower part of tomato plants to the middle and upper parts, whereas eggs were mainly found in the middle and upper parts of plants. [Conclusion]  Control of T. absoluta in greenhouses should be focused on ventilated areas on the sides of the greenhouse and at the entrance. Deploying pheromone traps in combination with red sticky plates near the ground can significantly improve trapping efficiency.
