Abstract
Subterranean termite control studies in a tropic area (Panama) are described. Testing was first started in 1943 on Barro Colorado Island, which was formed when the Panama Canal was completed in the early 1900's. Materials tested included DDT (various concentrations and formulations), BHC, trichlorobenzene, sodium arsenite, pentachlorophenol, sodium flurosilicate, copper ammonium fluoride, aldrin, chlordane, dieldrin, and heptachlor. Dieldrin (1.0 percent), applied to the soil as a water emulsion, was still 100 percent effective after 27 years when the tests were terminated. Tests with aldrin, chlordane, and heptachlor were initiated in 1963 and all three chemicals were still 100 percent effective after 16 years.
