Abstract: This invention relates to an improved system for releasing beneficial mites and the use of such a system. Mite species that can be used beneficially for human purposes may for example be employed in the control of pests, such as in the field of agriculture, including agricultural production systems for plant products, agricultural production systems for animal products, and animal husbandry, or in the field of storage of food products. The system of the invention may find use in any of these fields.

Abstract: The invention relates to a method for dispensing a particulate material in a target area and a device suitable for use in the method. The method comprise (i) providing a reservoir comprising openings for the particulate material, (ii) providing a number of closing means suitable for at least partially closing the openings of the reservoir (iii) providing a number of screens in the void of the reservoir, said screens being movable, through the void of the reservoir between at least a first and a second position (iv) loading particulate material in the reservoir, (v) moving the reservoir loaded with particulate material over the target area and at least partially opening the number of openings while alternatingly moving the screens between a first and a second position and vice versa.

Abstract: The present invention relates to a method for distributing particulate material in a target area. The method comprises the steps of (i) providing in a reservoir particulate material comprising particles to be distributed in a target area, which reservoir is provided with exits, (ii) providing a gas displacer, (iii) generating with the gas displacer a forced gas flow in the blow direction, and iv) directing the particles from the exits in the forced gas flow. The invention further relates to a device for performing the method according to the invention. Further aspects of the invention relate to the use of the device for distributing particulate material, a gas flow modification device, the use of such modification device for modifying the gas flow in a device for distributing particulate material and a kit of parts comprising (a) the gas flow modification device and (b) a device for distributing particulate material.
