| 520 | 3 |a"The impact of insect growth regulators Altosid and Dimilin on selected non-targeted organisms was determined during experimental applications for mosquito control in British Columbia. Residues in water, persistence in the environment, and effects on aquatic crustaceans and insects of the two growth inhibitors were monitored. Altosid was effective against mosquitoes and appeared harmless to marsh crabs, crustaceans, and fish at the Tsawwassen salt marshes. Dimilin treatments at Fort Langley, B.C., suppressed mosquito populations and reduced the population of zooplankton and certain non-target insects. Residues of these growth regulators were relatively persistent in the environment. The implications of these findings, and the effectiveness of insect growth regulators as mosquito control agents and their environmental consequences are discussed"--Abstract, page i. |
