摘要

Tests of soil termiticide efficacy should consider termite behavioral reaction to the toxicant. This chapter outlines a series of four separate bioassays that account for factors such as bioavailability, dose acquisition, route of entry, movement of intoxicated termites, and collective decision making that are important in modeling termite population response to field application. Results with seven different formulated termiticides indicate that the moniker repellent or non-repellent are a function of concentration not the purview of any particular class of chemistries. Bioavailability was evident in that mortality decreased with all active ingredients tested in bioassay with sandy loam soil compared to play sand with one exception, imidacloprid. Data included evidence that acquisition of a dermal dose is slow, requiring over one hour continuous exposure to treated sandy loam soil to produce >50% mortality at 10 ppm with all the formulations tested. Dermal and oral toxicities varied within all termiticides but one - fipronil - and all but one, the chlorfenapyr formulation, affected worker termite performance on an experimental trail compared to controls. Three behavioral conditions that must be considered when interpreting termiticide efficacy bioassay data are also discussed. First, the main route of entry for subterranean termites confronted with a soil-based insecticide is oral. Second, assignment of the task of gallery construction to specific workers and third, a collective decision making system of communication used by worker termites traveling through a network of galleries. It is therefore unlikely that consistent transfer of soil-borne toxicants will follow field application of any termiticide. A choice bioassay design is suggested as a more realistic approximation of termiticide field efficacy.
