Orientation and drifting behaviour of bumblebees (Hymenoptera: Apidae) in commercial tomato greenhouses

Abstract: A novel environment lacking in directional cues may present orientation challenges to foraging bees. We examined orientation and drifting behaviour of Bombus occidentalis Greene and Bombus impatiens Cresson, the two major bumblebee pollinators of greenhouse tomatoes in British Columbia. Our objectives were to establish the extent and frequency of bee drift into foreign colonies and to examine the potential of nest entrance patterns and landmarks to reduce drift in commercial greenhouses. On average, 28% of mar… Show more

“…The uniformity of a greenhouse environment may further promote bee disorientation and loss, leading to increased bee drift, subsequent pollination decline, and colony expenditure increase. However, when bumble bees were provided with nest entrance patterns or large landmarks scattered throughout the greenhouse, the amount of bee loss and drift was not reduced (Birmingham and Winston 2004), suggesting that alternative biologically important factors may affect the propensity for worker bees to drift.…”

“…fundadora podían tomar un territorio dentro de la colonia luego de que se apareaban (fase poligínica). El comportamiento de invasión ha sido reportado anteriormente en obreras de A. mellifera, B. occidentalis y B. impatiens (Birmingham et al 2004). Según Birmingham et al (2004), el comportamiento de invasión puede aumentar la capacidad reproductiva ("fitness") de los individuos invasores (parasitismo social).…”

“…El comportamiento de invasión ha sido reportado anteriormente en obreras de A. mellifera, B. occidentalis y B. impatiens (Birmingham et al 2004). Según Birmingham et al (2004), el comportamiento de invasión puede aumentar la capacidad reproductiva ("fitness") de los individuos invasores (parasitismo social). Lo anterior puede ser corroborado debido a que las dos reinas invasoras que se establecieron en la colonia CF y que lograron poner huevos, se favorecieron de las obreras presentes en la colonia (incubación, termorregulación, forrajeo).…”
