Super Sleuths Put The Bite On Tough Bugs FRESNO, Calif. (UPI) Why do some mosquitos refuse to c u r l up and die when doused \viili lethal closes of insecticides? After three years of research, the scientists have come to the conclusion (hat certain strains of mosquilos are able to shrug off the effects of insecticides by disposing of an oxygen by-product produced by the insecticide. The research was conducted by Donal Mengle, Lorry l.ewal- lon, Patricia Gillies and William Wilder of the California State Department of P u b l i c Health's insect control station in Fresno. They reported their findings at the a n n u a l meeting of the F.nlomological Sodely of America. Using radioactive substances, the researchers investigated the effects of parathion, a phosphate insecticide widely used in mosquito abatement work. They concluded t h a t parathion in ilself probably docs not kill the insect. "Actually, when a mosquito ingebls some of (he poison, its body mechanism manufactures a substance called paraoxon," Mengle said. "The paraoxon kills Ihe mosquito." The scientist said paraoxon, an oxygen by-product, is even more toxic than parathion. But some rnosquitos are able to dispose of it before its lethal effects begin. The researchers studied strains of Aedes mosquitos called Nigromaculis. They found two which were resistant to the phosphate insecticides. The research was conducted by feeding radioactive insecticides to Nigromaculis larvae. After a time, the larvae were ground up and the parathion and paroxon contents were analyzed. The sleuths found par- aoxon in the ones which died but none in those which lived. They now are searching for ways to block Ihe body metabolism of the resistant strains and make them susceptible to the insecticides.
