"This document presents the proposed regulatory decision for the re-evaluation of Bacillus sphaericus strain 2362. Bacillus sphaericus strain 2362 is a microbial insecticide registered for control of mosquito larvae in various aquatic habitats. In Bacillus sphaericus strain 2362, insecticidal activity is attributed to two distinct toxin types: the mosquitocidal toxin (Mtx) and the binary toxin (Btx). Btx is produced during sporulation and contributes to the primary toxic activity of commercial insecticidal strains after ingestion by mosquito larvae. Mtx exhibits lower insecticidal activity. As production batches of B. sphaericus strain 2362 are produced in a manner to permit sporulation and formation of Btx, little Mtx is expected to remain and additional processing into the end-use products further inactivates the toxin"--Page 1.
