Figure 5 and Figure 6 show selected time series results for calculated concentrations of resmethrin
A critical new study by a group of scientists and practitioners, concludes, "We find that ULV applications of resmethrin
had little or no impact on the Culex vectors of WNv, even at maximum permitted rates of application, [and] such insecticidal aerosols, delivered from the road, may not effectively reduce the force of transmission of WNv.
ABSTRACT Results for hindcast simulations are presented for the transient concentration distributions in Long Island Sound for the pesticides malathion, resmethrin
and sumithrin for the period August 1, 1999 through October 19, 1999.
Three cases involved resmethrin
, which belongs to the family of pyrethroids, synthetic derivatives of pyrethrins.
The products include major agricultural chemicals, such as the weedkiller, 2,4-D, and chemicals found in the majority of household insecticides, including boric acid, resmethrin
The type segment is further classified in to bifenthrin, deltamethrin, permethrin, cypermethrin, cyfluthrin, lambda-cyhalothrin and other pyrethroids (fenvalerate, resmethrin
, tetramethrin, allethrin, phenothrin, barthrin, dimethrin, and bioresmethrin).
The metabolite 3-PBA represents exposure to permethrin, cypermethrin, deltamethrin, allethrin, resmethrin
, fenvalerate, cyhalothrin, fenpropathrin, and tralomethrin; and cis- and trans-DCCA represent exposure to the cis- and trans- isomers, respectively, of permethrin, cypermethrin, and cyfluthrin (Barr et al.

1) In Canada, the natural pyrethrins and the synthetic pyrethroids permethrin, allethrin, tetramethrin, phenothrin and resmethrin
are registered for residential use.
Acute toxicity of resmethrin
, malathion and methoprene to larval and juvenile American lobsters (Homarus americanus) and analysis of pesticide levels in surface waters after Scourge, Anvil and Altosid application.
Peter Montague, writing for the Environmental Research Foundation, says there seems to be a strong link between brain cancers and products used to kill fleas and ticks like pyrethrins (natural) and pyrethroids (synthetic pyrethrins: permethrin, tetramethrin, allethrin, resmethrin
, and fenvalerate), and chlorpyrifos (known as Dursban).
Two of the most commonly used insecticides were Scourge (aa) (Bayer CropScience LP, Montvale, NJ) containing 4% resmethrin
and 12% piperonyl butoxide, and Anvil 10+10 ULV (bb) (Clarke Inc, Roselle, Illinois) with 10% 3-Phenoxybenzyl-(1RS, 3RS; 1RS, 3SR)-2,2-dimethyl -3-(2-methylprop-1-enyl) cyclopropanecarboxylate.
