【目的】 黄胸蓟马Thrips hawaiiensis是香蕉上的主要害虫之一，其危害会降低果实外观品质，并造成重大经济损失。本研究旨在探明黄胸蓟马对香蕉的危害症状、分布特征和对不同组织的选择性。【方法】 田间调查香蕉不同组织上黄胸蓟马的危害症状和分布特征，室内用“Y”型嗅觉仪测定黄胸蓟马对香蕉花蕾不同组织、叶片和假茎的选择。【结果】 黄胸蓟马危害香蕉花蕾的果轴、苞片、花蕊和幼果，危害处表面形成突起黑点。幼果上的黑点数最多，为2 361.2个，花蕊次之，为537.7个，果轴最少，为97.7个。黑点在果实上的分布，以果实背面数量最多，为77.0个，腹面（52.8个）和侧面（左：57.3个；右：52.7个）数量显著低于背面（P<0.05）。相较于空白对照，花蕾不同组织幼果、雄蕊、苞片、假茎、叶片和果轴对黄胸蓟马的引诱率分别为83.3%、73.3%、73.3%、45.0%、38.3%和40.0%，黄胸蓟马对幼果具有极显著的选择偏好性（P<0.001）。对黄胸蓟马有引诱性的花蕾组织两两比较，幼果和苞片间的引诱率差异不显著（P>0.05），但均高于花蕊。【结论】 黄胸蓟马对香蕉花蕾不同组织均会造成危害，其中幼果受害最为严重，同时也是对黄胸蓟马引诱率最高的组织。研究结果为黄胸蓟马为害特征识别及其综合防控提供了理论基础。

 [Aim]  To investigate the relative preference of Thrips hawaiiensis for different banana tissues, the symptoms of crop damage caused by this pest, and its distribution on banana plants. [Methods]  Symptoms of T. hawaiiensis damage to different plant tissues were surveyed and the relative preference of T. hawaiiensis for different banana bud tissues were tested using a Y-tube olfactometer in a laboratory. [Results]  The bracts, fruit axis, stamen and pistils, and young fruits of banana plants can all be damaged by T. hawaiiensis. The main damage symptom are raised black spots on the epidermal surface. The average number of black buds was 2 361.2 on young fruits, 537.7 on the pistil and stamens and 97.7 on the axil. The number of black spots on the dorsal surface of fruits was significantly higher than on the ventral or lateral surfaces (P<0.05). Compared to the control, the relative preference of T. hawaiiensis for young fruits, stamen and pistils, bracts, pseudostems, leaves and the fruit axis was, respectively 83.3 %, 73.3 %, 73.3 %, 45.0 %, 38.3 % and 40.0 %. A significant preference for young fruits was apparent (P<0.001). There was no significant preference for young fruits over bracts (P>0.05), but both were preferred over stamen and pistils. [Conclusion]  T. hawaiiensis can damage different tissues of banana buds, including young fruits, stamen and pistils, bracts and the fruit axis. Young banana fruits are significantly more attractive to T. hawaiiensis than other tissues. These results provide a reference for identifying T. hawaiiensis damage on banana plants, and the comprehensive prevention and control of this pest.
