“…Bees are commonly used for greenhouse pollination of various crops, including tomatoes and bell peppers, which are normally pollinated by bumble bees, mainly Bombus terrestris (L.) (Free, 1993;Velthuis & van Doorn, 2006). Stingless bees, such as Tetragonisca angustula (Latreille) and Nannotrigona spp., have also been found to be efficient pollinators of tomatoes (Del Sarto et al, 2005), peppers (Santos et al, 2008), strawberries (Malagodi-Braga & Kleinert, 2004) and cucumbers (Nicodemo e al., 2013). These stingless bees are considered effective and useful pollinators in greenhouses because they are generalist foragers, have a tendency for flower fidelity, do not attack agricultural workers who tend the crop, rarely abandon their nests and store food (Slaa et al, 2006).…”
