Abstract
Most of 72 esters of organic acids tested as lures for eye gnats (Diptera: Chloropidae) in California were attractive to Conioscinella flavescens (Tucker) and Siphonella neglecta Becker, and 2,4-hexadienyl butyrate and propyl 2-heptynoate were particularly attractive. Octyl butyrate, though not especially attractive to C. flavescens, was the most attractive lure to S. neglecta. Hexyl crotonate was highly attractive (equal to 2,4-hexadienyl butyrate) to C. flavescens but not to S. neglecta. A positive correlation coefficient (0.618) was found for the numbers of specimens of the 2 species that responded to the various lures. Heptyl butyrate showed minor attraction to Hippelates collusor (Townsend).
