Abstract

Traps baited with a 1 : 1 : 1 mixture of Grandlure I [cis-1-methyl-2-(1- methylenethenyl)-cyclobutaneethanol], Grandlure II [(Z)-2-ochtoden-1-ol; (Z)-2-(3,3-dimethylcyclohexylidene)ethanol] and Grandlure III-IV [(Z)- and (E)-2-ochtodenal; (Z)- and (E)-(3,3-dimethyl)cyclohexylidene)acetaldehyde] caught significantly more Conorrhynchus (Cleonus) mendicus Germar (Col.: Curculionidae) weevils than traps without bait. Later tests revealed that only Grandlure III-IV was responsible for attractivity. Both sexes were attracted according to a random sample of captures. C. mendicus appeared to be very similar in its responses to the synthetic aggregation attractant as the closely related Bothynoderes (Cleonus) punctiventris (Germar), in which species, the attraction to Grandluree III-IV has recently been published. Doses from 500 to 5000 μg of Grandlure III-IV on rubber dispensers performed satisfactorily in monitoring trials and can be recommended for use in practical trapping applications for C. mendicus.
