Abstract:
Novel attractants for the Mediterrean Fruit Fly, "Medfly," are disclosed. The attractants comprise isomeric blends of esters of iodo-trans-2-methylcyclohexanecarboxylic acid. In use, the attractants are competitive in attraction with the "standard" Medfly attractant, Trimedlure, "TML," but are much more persistent than TML.

Abstract:
A process of separating cis and trans isomers of cyclopropane carboxylic acids comprising the step of treating an aqueous solution of a soluble salt of the cis and trans isomers with just sufficient of an acid, for example acetic acid or carbonic acid, to cause precipitation of one isomeric form of the cyclopropane carboxylic acid while substantially all or a major proportion of the other isomeric form remains in solution as the soluble salt. The process may be used, for example, to separate (+)-cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylic acid (an intermediate for insecticides) from a mixture of the (+)-cis and (+)-trans acids.
