Summary from sciencedaily.com
The yield and quality of many crops benefit from pollination, but it isn't just honey bees that do this work: bumble bees also have a role. A team has used innovative molecular biological methods and traditional microscopy to investigate the pollen collecting behavior of honey bees and bumble bees in agricultural landscapes. It turns out bumble bees take much more pollen from different plant species than honey bees to satisfy their need for protein.
bumble bees are superior pollinators of tomatoes than the honey bee. The southern carpenter bee also pollinate tomatoes.
