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.

Persistant attractants for the mediterranean fruit fly, the method of

Certain cyclohexyl and cyclohexenyl aliphatic alcohols and ketones are potent attractants for Dacus latifrons, the Malaysian fruit fly. By attracting adult males to field traps, the compounds provide a means for detecting, monitoring, and controlling this agricultural pest.

A number of novel amides were found to be highly effective as cockroach repellents.

Cockroach repellents

A number of novel tetrahydro-pyridinyl amides were found to be highly effective as cockroach repellents.

Novel lower alkyl esters of iodo-trans-2-methylcyclohexanecarboxylic acid are useful to attract the Mediterranean Fruit Fly, 'Medfly,' for prolonged periods of time. The esters are competitive in attraction with the current 'standard' attractant, Trimedlure, but are much more persistent. The esters may be economically produced and possess the dual properties required for effective use in Medfly control programs.

Persistent attractants for the mediteranean fruit fly, the method of

Certain esters of 4(and 5)-chloro-trans-2-methylcyclohexanecarboxylic acid act in a dual and advantageous capacity when added to the Mediterranean fruit fly attractant, trimedlure. They greatly reduce or eliminate crystallization of the solid trimedlure isomers that occurs on storage or use during cool weather and they significantly extend the attractive activity of trimedlure.

Additives useful as crystallization inhibitors and activity extenders
