Journal of Applied Entomology, Volume 149, Issue 10, Page 1520-1531, December 2025.ABSTRACT Wasps, members of over 90 hymenopteran families, exhibit diverse behaviours, including pollination, predation and parasitism. While wasps are known pollinators in specialised systems, such as the intricate mutualism of fig trees and the deceptive pollination of certain orchids, they have historically been considered ineffective pollinators ...
