A new version of the device patented by University of Catania and already used in natural enemy distribution trials on greenhouse vegetable crops has been designed and built in order both to increase the work capacity and to promote a low impact pest control. This version has the same working principle of the former prototype, but materials and dimension of the hopper, the distributor and the rotating disc have been changed. With this model, set on a handle directly carried by the operator, the device performance will be essentially improved in manoeuvrability within a greenhouse. Negligible or absent impact on natural enemies proves prototype efficacy and enables its usage both with technical and economic advantages on manual distribution.
