白蚁经常通过相互梳理毛发直接消除病原体，从而防止昆虫病原真菌的感染。我们前期的研究证实，乳白蚁的触角对昆虫病原真菌的霉味反应灵敏。然而，尚不清楚这种气味是否对白蚁的行为有任何影响。本研究的目的是阐明真菌气味对白蚁行为的影响，特别是对分生孢子去除的影响。通过将分生孢子浸入蒸馏水中，将霉味制成水溶液。当未经处理的白蚁与经真菌气味处理的白蚁以4:1的比例混合时，经常观察到经处理的白蚁相互梳理和攻击。这表明真菌气味引发了这些行为反应。虽然在所有测试的昆虫病原真菌中都发现了真菌气味的某些成分，但不同分离株的气味特征有所不同。
Termites often eliminate pathogens directly through mutual grooming, and are thereby prevent infections from entomopathogenic fungi. Our previous study confirmed that the antennae of Coptotermesformosanus sensitively responded to the musty odor of entomopathogenic fungi. However, it is unclear if this odor has any effect on termite behavior. The purpose of this study was to clarify the effects of fungal odor on termite behavior, especially on conidia removal. The musty odor was prepared as an aqueous solution by immersing conidia in distilled water. When untreated termites were mixed with fungal-odor-treated termites at a ratio of 4:1, mutual grooming and attack of treated termites were frequently observed. This indicated that the fungal odor triggered these behavioral responses. While some components of the fungal odor were found in all of the entomopathogenic fungi tested, the odor profiles differed among the isolates.
