Foraging Behavior of Odontotermes formosanus (Shiraki) (Isoptera:Termitidae) Workers to the Pinus massoniana Wood Powder and the Powder Infected by Brown Rot fungus Gloeophyllum trabeum

Objective]To provide references for the further study of feeding habits of workers and the exploitation of baiting techniques,we investigated the foraging behavior of Odontotermes formosanus ( Shiraki ) workers to the Pinus massoniana wood powder and the wood powder infected by Gloeophyllum trabeum and the attractive activity of the P. massoniana wood powder infected by G. trabeum to workers. [Method]A feeding device of O. formosanus was constructed by using Y-tube olfactometer as the main part and then foraging behavior of workers was observed. The selective preference of workers to the different wood powder was observed by using Y-tube olfactometer. [Result]The foraging behavior of the workers mainly consists of olfactory reception,exploration and identification of the food,and recruiting other foragers in the feeding device of Y-tube olfactometer. The foraging behavior to the pine wood powder with or without infection by G. trabeum was quite similar,but there were some differences in the time of different
