摘要：

【目的】明确黑翅土白蚁Odontotermes formosanus巢群的觅食群体大小与工蚁体长之间的关系，为进一步研究其生态学特点以及更好地开展防治提供依据。【方法】在杭州植物园内选择5处有黑翅土白蚁活动区域作试验点，诱捕并以中性红(neutral red)标记捕获的白蚁工蚁，通过“捕获-标记-释放-重捕”试验测定黑翅土白蚁的觅食群体大小。【结果】5个试验点中有4个成功实施了“捕获-标记-释放-重捕”试验，4个试验点黑翅土白蚁巢群的觅食群体个体数量分别为443 133±45 469, 495 360±67 429, 674 345±101 703和1 224 662±93 112头。黑翅土白蚁觅食群体大小(Y)与觅食工蚁的体长(X)呈正相关，拟合的指数函数方程式为：Y=1.8389e^0.7185X(R²=0.7834)。【结论】本研究明确了黑翅土白蚁的觅食群体大小以及工蚁体长之间的函数关系，为开展区域防治提供了依据。

Abstract: 【Aim】 This study aims to clarify the relationship between the foraging population size and body length of workers of the black-winged termite, Odontotermes formosanus, so as to lay a foundation for ecological studies and area-wide termite management. 【Methods】 Five test sites abundant with O. formosanus termites in Hangzhou Botanical Garden were selected. Worker termites were captured and labeled with neutral red. The foraging population size of O. formosanus colony at each test site was determined by capture-mark-release-recapture experiments. 【Results】 The capture-mark-release-recapture experiments were successfully implemented at four of the five test sites. The foraging population sizes of O. formosanus colonies of the four test sites were 443 133±45 469, 495 360±67429, 674 345±101 703 and 1 224 462±93 112, respectively. A positive correlation was found between the foraging population size in O. formosanus colonies (Y) and the body length of workers (X), which fitted the exponential function, Y=1.8389e^0.7185X(R²=0.7834). 【Conclusion】 This study clarified the functional relationship between the foraging population size and body length of workers of O. formosanus, providing basic data for areawide termite management strategy.
