Two dispenser types for pine sawfly (Hymenoptera: Diprionidae) pheromones-glass capillaries and dental cotton rolls-are described, and release rates reported. Glass capillaries of different diameters were used in field tests to determine dose-response relationships of (2S,3S,7S)-3,7-dimethylpentadecan-2-yl acetate (diprionyl acetate), diprionyl propionate, andtrans-perillenal on the trap catch of maleNeodiprion sertifer. A linear relationship between the logarithm of the capillary cross-sectional area and the logarithm of the release rate was found. However, capillaries of the same diameter could vary in the amount released by as much as a factor of 10. Both the acetate and propionate were attractive alone, but no synergistic effect was found.trans-Perillenal did not show any behavioral activity. Dental cotton rolls have been used extensively in diprionid pheromone research without knowledge about release rates. The release rate from rolls loaded with different amounts of diprionyl acetate was determined by extracting rolls after different times under constant temperature and wind conditions or after use in field tests. Quantification of diprionyl acetate was done on GC. The release rate was found to be proportional to the amount applied over several orders of magnitude, and persisted for several weeks. Capillaries and rolls with similar release rates caught similar numbers of sawflies.
描述了两种松叶蜂信息素（膜翅目： Diprionidae）分配器类型-玻璃毛细管和牙卷棉，并报告了释放率。在野外试验中使用不同直径的玻璃毛细管，以确定（2S，3S，7S）-3，7-二甲基十五烷-2-基乙酸酯（双酰乙酸），双酰丙酸和反-全反式-金合欢烯醛对雄性 Neodiprion sertifer 诱捕器捕获的剂量反应关系。发现毛细管横截面积的对数与释放率的对数之间存在线性关系。但是，相同直径的毛细管在释放量上可能相差多达 10 倍。乙酸酯和丙酸酯单独使用均具有吸引力，但未发现协同作用。反-全反式-金合欢烯醛没有表现出任何行为活性。牙卷棉在 Diprionid 信息素研究中得到了广泛的应用，而不知道释放率。通过在恒温恒风条件下或在野外试验中使用后不同时间提取卷，确定了装有不同量双酰乙酸的卷的释放率。通过 GC 对双酰乙酸进行定量。发现释放率与施加量成比例，在几个数量级上均保持稳定，并持续数周。释放率相似的毛细管和牙卷棉捕获了相似数量的松叶蜂。
