RESUMO
This study aimed to observe the attractiveness efficiency of trap boxes installed in collective shelters of stingless bee colonies (Melipona flavolineata, Melipona fasciculataand Scaptotrigona aff.depilis), as an alternative method for non-chemical control of tracuá carpenter ants (Camponotus atriceps). The study was conducted at Embrapa Amazônia Oriental, in Belém, Pará, Brazil, from March to August 2015. The results showed that the efficiency of this technique depended on the presence of bee colonies and on the bee species in the collective shelter. Overall, an efficiency of 40.6% was found in the capture of C. atricepsindividuals, which rose to 75% considering only collective shelters ofM. fasciculata colonies, and to 87.5% for collective shelters ofM. flavolineata. Trap boxes installed in collective shelters of S. depilisdid not attract any C. atricepsgroup or individuals. The use of trap boxes in collective shelters of stingless bee colonies of the genus Melipona (M. flavolineataand M. fasciculata) is an efficient alternative method of non-chemical control of tracuá carpenter ants (C. atriceps).(AU)
