Method and device for distributing a particulate material

A method for distributing particulate material comprising a composition comprising beneficial arthropods, said method comprising:

• (i) providing in a reservoir the composition comprising beneficial arthropods to be distributed in a target area, wherein the reservoir comprises a number of exits for the particles of the composition;
• (ii) providing a gas displacer suitable for generating in a blow direction a forced gas flow that can carry the particles of the composition;
• (iii) generating with the gas displacer in the blow direction the forced gas flow that can carry the particles of the composition;
• and
• (iv) distributing the particles of the composition by introducing the particles of the composition from the exits in a distributing gas flow that carries the particles in the blow direction, wherein the distributing gas flow is formed from the forced gas flow;
• wherein a plurality of channels is provided, each channel comprising an inlet, an outlet and an elongated hollow body connecting the inlet and outlet, said channels adjoining at least at the outlets, wherein the inlets are designed such that at least a part of the forced gas flow flows through the channels and the outlets are designed to direct the forced gas outflows in substantially the same direction, such that the forced gas outflows from the plurality of outlets and combines to form the distributing gas flow, and the particles of the composition are introduced from the exits of the reservoir in the distributing gas flow after the forced gas outflows have outflown from the plurality of outlets and have combined to form the distributing gas flow.
