Liquid Chemicals for Inhibiting the Damage of Odontotermes formosanus and Macrotermes barneyi (Isoptera: Termitidae) to Trees

The Objectives of this research were to compare the ability of fenvalerate, ivermectin and fipronil to control the damage of Odontotermes formosanus Shiraki and Macrotermes barneyi Light to trees in Huagaishan Park and Cuiweishan Park, Wenzhou city, Zhejiangprovince, China during the period of August 2008 to October 2009. The results of irrigating liquid chemicals in the soil around the base of trunks indicated that 0.05%similar to 0.4% fenvalerate solutions and 0.003125%similar to 0.025% fipronil solutions effectively retarded termite attacks on trees. However, 0.0025%similar to 0.02% ivermectin solutions could only repress infestation by O. formosanus and NI. barneyi for a shorter amount of time. This information shows fenvalerate and fipronil are preferable to ivermectin for the control of O . formosanus and M. barneyi.
