Abstract: An outlet head (22) for a spray device (10), the outlet head (22) comprising an inlet section (31) having an opening (30) adapted to receive an output section (20) of a spray material container (16), said opening (30) forming a first end of a fluid channel for spray material from the spray material container (16), the outlet head (22) also comprising an outlet portion (14) adapted to eject spray material and forming a second end of the fluid channel for spray material, wherein the inlet section (31) has a first, major, lateral axis and a second, minor, lateral axis, said first and second axes being substantially at right angles to one another, wherein the size of the inlet section along the first, major, axis is greater than the size of the inlet section along the second, minor, axis.

Abstract: Computer system for calculating a pharmacokinetic behavior of a chemical substance in insects, comprising: a physiologically based pharmacokinetic simulation model (102) of an insect for predicting concentration/time profiles of the chemical substance in compartments of the insect, the simulation model having at least one parameter which is dependent on the substance, and a prediction module (110) for predicting the at least one parameter on the basis of a physicochemical property of the substance.
