In hybrid seed crops, drone flies are more efficient pollinators than honey bees. They are 11 times more likely to deliver pollen from fertile to sterile flowers in carrot and three times more likely in radish.
Drone flies are among the most efficient pollinators of hybrid crops including carrot, onion and radish. Because they move between male fertile and sterile lines more frequently than honey bees, they deliver pollen more frequently and fewer are needed to have the same pollination outcome.
This factsheet explains how to build your own, portable, drone fly rearing facilities...set them up in the paddock or shift them in when required.
