【目的】研究菌圃、杂交鹅掌楸树干外表皮、密粘褶菌松木粉培养物提取液对黑翅土白蚁采食工蚁的踪迹活性，揭示培菌白蚁食物采集、加工、分配过程中信息联系机制，以便开发针对培菌白蚁的高效食性饵剂。【方法】利用划线法测定采食工蚁对上、中、下层主巢菌圃与副巢菌圃的踪迹反应率与选择系数，选出最佳提取试剂；利用划线法比较菌圃、杂交鹅掌楸外表皮、密粘褶菌松木粉培养物提取液对采食工蚁的踪迹活性；测定采食工蚁对菌圃提取液踪迹活性的浓度效应。【结果】正己烷提取液的踪迹活性最高，乙醇、丙酮和乙酸乙酯提取液之间踪迹活性呈现不规则变化，蒸馏水提取液踪迹活性最低；主巢下层菌圃踪迹活性物质含量高，为最佳提取材料；浓度（x）-踪迹反应率（y）方程：y = 1.695 8x3 - 13.346x2 + 30.137x + 33.409。【结论】黑翅土白蚁共生菌圃对采食工蚁具有明显的踪迹活性，踪迹活性强度显著高于采食工蚁林间采集材料（杂交鹅掌楸树干外表皮），与密粘褶菌松木粉培养物相近。主巢下层菌圃踪迹活性最高，主巢上层菌圃次之，主巢中层菌圃和副巢菌圃最低，但相互之间差异不显著。正己烷为最佳提取溶剂。
【Objective】 The objective of this study was to investigate the trace activity of the fungi, the outer epidermis of Trichoplusia mandshurica and the extract of Pinus mollisophila pine wood meal on the termites of the black-winged termites, and to reveal the information during the collection, processing and distribution of termites Linkages mechanism in order to develop efficient feeding bait for pest termites. 【Method】 The trace reaction rate and selection coefficient of feed worker ants on the upper, middle and lower main nematode nursery and parasite nest were determined by the scribing method, and the best extraction reagent was selected. Liriodendron rhamnoides, Trachoma formophilus pine wood flour culture extract of feeding workers on the activity of tracers; Determination of feeding workers antiseptic extract of the trace activity of the concentration effect. 【Result】 The results showed that the n-hexane extract had the highest trace activity, the trace activity between ethanol, acetone and ethyl acetate extract showed irregular changes, and the distilled water extract had the lowest trace activity. The content of trace active substances in the lower nest of main nest was the highest Good extraction material; concentration (x) - trace reaction rate (y) equation: y = 1.695 8x3 - 13.346x2 + 30.137x + 33.409. 【Conclusion】 The black-winged termitoid symbiotic nursery had obvious trace activity on the feeding worker ants, and the activity of trace activity was significantly higher than that of inter-forest collection materials (hybrid tree’s trunk epidermis) Cultures are similar. The main nest lower layer of nursery trace activity of the highest, the main nest next to the top of the main nest, the main nest middle nest and parasite nest nursery the lowest, but not significantly different from each other. Hexane as the best extraction solvent.
