    Activity of precocene analogs onLocusta migratoria migratorioides (R. and F.)[Reference: WebLink]
    Several analogs of precocene have been synthesized and evaluated as potential inhibitors of juvenile hormone on Locusta migratoria. Only 5,7-dimethoxy-2,2-dimethylchromene was active; its ED50 and LD50 were measured and compared to those of precocene I and II.
