Request: Please note the request for literature on the efficacy of malathion for public health pests (mosquitoes).

Steve Toth ------------------------------------------------- Dear Colleagues: The registrant Cheminova is intending to comply with an EPA request for efficacy data for the use of malathion for public health pests. Because the costs of generating efficacy data according to GLP requirements would excessive, Cheminova reviewed the public literature but could only find certain data for mosquitoes for one of their products. Efficacy Data and/or Published Literature are needed for: 50 % and 57% Emulsifiable Concentrate (flies, biting flies, midges, other public health pests AND mosquitoes) (there are numerous formulations) Fyfanon ULV (flies, biting flies, midges, other public health pests - NONE needed for mosquitoes) (EPA Reg. Number 67760-34) If you are aware of any data or literature data, please send to No immeidate rush. We have several weeks to send any information on to EPA. Thank you!
