Larvae of the sugar-beet wireworm, Limonius californicus (Mannerheim), were exposed continuously for 26 and 80 days to soil treated with 2.5 and 1.56 ppm, respectively, of aldrin. Survival exceeded 20%. Aldrin was rapidly epoxidized to dieldrin and concentrated within the larvae. The total content of aldrin and dieldrin in exposed larvae rapidly declined after the larvae were placed in insecticide-free soil. Some insecticide was probably excreted. The susceptibility of larvae from 3 locations in eastern Washington did not vary significantly. Larvae tested in 1964 were much less susceptible than those tested in Washington during 1949-51.
