New trap "tailor-made" to capture spotted-wing Drosophila

Koppert Biological Systems has developed a new trap to help soft fruit growers capture, monitor and control the fruit fly pest spotted-wing Drosophila (SWD, Drosophila suzukii).

The Dutch company says the Drososan traps, set to be launched on the market this month, are more effective than standard traps.

Previously it offered its own Fruit Fly Attractant bait in combination with the generic yellow Moskisan trap to capture the fly, a recent arrival in Europe from the Far East.

In contrast, Drososan is red, a colour known to be particularly attractive to the soft fruit pest, while the openings in the gauze are tailored to the fruit fly's size.

Product manager Rick van der Pas said: "This eliminates the risk of capturing other insects. As the trap doesn't capture pollinators, growers can more easily count the number of specimens caught and gain a better insight into the level of infestation."

Independent research by the the Polytechnic University of Valencia in Spain has shown Drososan in combination with Fruit Fly Attractant to be more effective than a standard trap or the generic Moskisan trap, Koppert said.
