Termites are a significant pest of buildings, agriculture, and trees, and are mainly controlled by baiting. However, baiting systems are available for only lower termites (Rhinotermitidae) not for higher termites (Termitidae). Termite foraging behavior associated with baiting systems varies among species and families, and plays a significant role in baiting success. Here, foraging behavior of Odontotermes obesus (Blattodea: Termitidae: Macrotermitinae), a fungus-growing higher termite, was investigated relative to three bait-station sizes (small, medium, and large) containing different quantities of food. Significantly more workers recruited to large stations (470/station) compared to medium (246/station) and small (124/station) stations. Abundance of O. obesus in large and medium stations significantly positively correlated with relative humidity whereas negative but non-significant correlations were observed with temperature in large and medium stations. Total and continuous contacts with the stations increased with time and were greater in large stations. Station abandonment due to disturbance was significantly less in large stations (3%) followed by medium (9%) and small stations (20%). Our results suggest that large stations (≈8 litres volume) work best for population management of O. obesus and other related fungus-growing higher termites.

清除白蚁 Odontotermes obesus (Blattodea: Termitidae) 的觅食行为和诱饵站偏好

白蚁是建筑物、农业和树木的重要害虫,主要通过诱饵控制。然而,诱饵系统仅适用于低等白蚁(Rhinotermitidae),不适用于高等白蚁(Termitidae)。与诱饵系统相关的白蚁觅食行为因物种和科而异,并且在诱饵成功中起着重要作用。在这里,觅食行为齿白蚁(Blattodea:白蚁科:Macrotermitinae)是一种生长真菌的高等白蚁,研究了相对于包含不同数量食物的三个诱饵站大小(小、中和大)。与中型(246/站)和小型(124/站)站相比,大型站(470/站)招聘的工人明显更多。丰富的O. obesus大中站与相对湿度呈显着正相关,而大中站与温度呈负相关但不显着。与车站的总接触和持续接触随着时间的推移而增加,并且在大型车站中更多。大型车站(3%)因干扰而放弃车站的情况明显较少,其次是中型车站(9%)和小型车站(20%)。我们的结果表明,大型站(≈8 升体积)最适合于人口管理O. obesus和其他相关的真菌生长的高等白蚁。
