Conteúdo: | Proprietary trunk barriers (AntCaps) were evaluted as a means of excluding Indomymex spp. and other ants from the canoples of young orange trees. Untreated AntCaps were relatively ineffective, reducing ant movements along trunks by 17% at one site and having no positive effect at the second site over a 7 month period. Cypermethrin-treated AntCaps effectively reduced ant foraging in tree canoples over the same period. Trunk movements were reduced by 92 and 84% at the two sites despite a mean 'failure' rate of 21% across all sampling days. Estimates of overall efficacy based on beating samples correlated well with trunk counts for the a-Cypermethrin-treated barriers. The correlation between efficacy estimates for the untreated barriers was poor,  aas was the overal correlation between assessment methods at the individual sample level.
