“…Small arthropods are known to be important pollinators of a range of other plant species. These include the Dipteran families Cecidomyiidae (Yuan et al 2007), Ephydridae (Nagasaki 2007), Drosophilidae (Miyake & Yafuso 2005), Sciaridae and Mycetophilidae (Mesler et al 1980), Phoridae (Rulik et al 2008), Chironomidae (Murugan et al 2006), Psychodidae (Albre et al 2003), small Coleoptera (Krantz 2004;Blanche et al 2006), small Hymenoptera (Herre et al 2008) and Thysanoptera (Kirk 1997). Moreover, the propensity for small arthropods, which may carry pollen, to be carried in air currents over many kilometres suggests a possible route for inter-crop and crop-weed pollen movement and may elevate the importance of these arthropods in the contamination of seed crops.…”
