Bumble bees are managed for their pollination services in a variety of crop systems, including tomatoes, fruit trees, berries, and soybean (Abrol & Shankar, 2012; Feltham et al., 2014; Stanley et al., 2015; Suzuki et al., 2007). Most commercial bees are used in greenhouses, including for the growth of berries, squash, eggplant, and peppers (Abak et al., 1995; Shipp et al., 1994; Strange, 2015). However, around 95% are specifically used in tomato greenhouses (Velthuis & van Doorn, 2006).
