Abstract

With the purpose of studying the foraging behavior of Apis mellifera Linnaeus 1758 and resources partitioning between A. mellifera and stingless bees, artificial baits containing water or a scented sucrose solution (5 %, 10 % and 30 % concentration) were placed in a caatinga area near Casa Nova city, Bahia state. NE' Brazil, during the dry season. The number of bees at baits was registered each 15 min. Africanized A. mellifera was the most abundant species on the baits, and foragers were most abundant at baits with higher sucrose concentration. The number of individuals of the stingless bees Plebeia (P.) spp diminished when there were 15 A. mellifera per bait, and dropped to 0 with 50 A. mellifera per bait. When replenishing with syrup was interrupted, the number of A. mellifera diminished and the number of Plebeia (P.) spp raised. Foragers of other stingless bees species (Melipona asilvai Moure 1971, Frieseomelitta doederleini (Friese 1900), Partamona cupira (Smith 1863), Trigona (T.) spinipes (Fabricius 1793)) foraged at baits in lower numbers. Wasps also visited the baits, increasing in number when A. mellifera was abandoning the baits. Agonistic encounters were seen between A. mellifera foragers at baits. The small stingless bees pursued a strategy of persistent insinuation when A. mellifera was present.

Kurzfassung

Zur Untersuchung des Sammelverhaltens von Apis mellifera Linnaeus 1758 sowie der Ressourcenteilung zwischen A. mellifera und stachellosen Bienen wurden in einem Caatinga-Gebiet in der Nähe der Stadt Casa Nova im Staat Bahia (Nordosten Brasiliens) während der Trockenperiode künstliche Köder aufgestellt, die Wasser oder eine wohlriechende Saccharose-Lösung (5 %, 10 % und 30 % Konzentration) enthielten. Die Anzahl der Bienen an den Ködern wurde alle 15 min. registriert. Die afrikanisierte A. mellifera erwies sich als die am zahlreichsten vorhandene Species an den Ködern; Sammler gab es am reichlichsten an Ködern mit höherer Saccharose-Konzentration.
