Subterranean termite foraging behaviour and the development of baiting methods used for termite control by the Division of Forest Products
J R J French, J W Creffield, B M Ahmed
Given the premise that alternatives to current subterranean termite control measures using organochlorine insecticides and arsenic trioxide have been actively researched by our Division for over ten years, emphasis on baiting methods in controlling these termites has been a major facet of our research. Recently, the new Australian Standard (AS 3660 -1993) was released which outlined the use of physical barriers (Granitgard and Termi-Mesh) as alternatives to soil chemical barriers. However, baiting methods have as yet not been incorporated into the standard. This paper describes the development of baiting techniques in laboratory and field experiments designed over the years to complement, and substitute for, the current soil chemical barrier approach. The goal is to bait or aggregate termites to a point source. In this situation, the termites may be fed bait toxicants that act as slow-acting stomach poisons, or dusted with toxicants that have a similar mode of action. The outcome is to affect colony destruction. Suggestions are offered to indicate the advantages of baiting techniques over soil chemical barriers. Furthermore, such techniques are used to rapidly evaluate potential termiticides and refine future termite control for the pest control industry.
