Reunion Island: New pollinating insect to fertilize the flowers of greenhouse tomatoes
Bumblebees have been used for almost 30 years to fertilize greenhouse tomato crops, however they don’t seem to be allowed to be imported to Reunion Island. This example forces producers to resort to guide fertilization, a expensive and time-consuming course of.
However the state of affairs is about to alter because of researchers who’ve developed a brand new pollination technique with a wild bee known as the xylocopa fenestrata.
ARMEFLHOR (Affiliation for the Modernization of the Fruit, Vegetable and Horticultural Financial system of Reunion Island) has developed, in partnership with CIRAD, a pollination technique with the xylocopa fenestrata, a species of Carpenter Bee that’s native of the island and also referred to as the charcoal fly as a consequence of its shade.
The exams performed on seven farms of the island present yields which might be 20 to 30% larger than with guide fertilization, in addition to higher calibers and high quality. “With this insect, the flowers flip into fruit, very similar to in metropolitan France with the usage of bumblebees,” explains Jean-Sébastien Cottineau, in control of experimentation at ARMEFLHOR. “Concretely, we have now a fertilization charge of 90%, typically much more in some areas, regardless of the succession of overcast days.”
