Most staple crops are not bee polinated. Wheat is ant polinated (so I've been told by local naturalists who should have the background to know - others are claiming wind).
"The flowers are wind-pollinated, with over 99% of pollination events being self-pollinations and the rest cross-pollinations.[6] "
No mention of ants, and the reference [6] says "Normally at anthesis, the lemma and palea are pushed apart temporally (lasting for 8–30 min) by lodicules swelling, and the pollen dehiscences from anthers and falls on the ovary to accomplish fertilization (de Vries, 1971)."
