Abstract

Un método para exterminar insectos voladores que comprende rociar, en el aire donde los insectos están volando, gotitas de líquido de una composicioninsecticida, y a dichas gotitas líquidas se imparte una carga unipolar mediante carga de doble capay separacion de la carga durante el rociado, y la cargaunipolar está a nivel tal que dichas gotitas de líquido tienen una relacion entre carga y masa de al menos +/- 1 x 10-4 C/kg. Un dispositivo de spray enaerosol, que es capaz de impartir unacarga unipolar mediante carga de doble capa y separacion de carga a gotitas de líquido de una composicion rociada desdeel mismo, posee una cabeza rociadora en forma de un inserto en un accionador, y la cabeza rociadora posee un orificio, a travésdel cual el líquido esexpelido, que posee una salida, de preferencia con una periferia sinuosa, con una relacion entre L/a de al menos 8, donde L es la longitud de la periferia quedefine la salida del orificio en mm y a es el área transversal de lasalida del orificio en mm2 y el aparato está construido de manera tal que las gotitas seanexpelidas desde la cabeza rociadora a un caudal de al menos 0,5 gramos por segundo y poseen una relacion entre la carga y masa de al menos +/- 1 x 10-4 C/kg.A method for exterminating flying insects comprising spraying, in the air where the insects are flying, liquid droplets of an insecticide composition, and to said liquid droplets a unipolar charge is imparted by double layer loading and separation of the charge during spraying, and the Unipolar charge is at a level such that said liquid droplets have a relationship between charge and mass of at least +/- 1 x 10-4 C / kg. An aerosol spray device, which is capable of imparting a unipolar charge by double layer loading and separation of liquid droplets from a composition sprayed therefrom, has a spray head in the form of an insert in an actuator, and the spray head It has a hole, through which the liquid is expelled, which has an outlet, preferably with a sinuous periphery, with a ratio between L / a of at least 8, where L is the length of the periphery, the exit of the hole is defined in mm It is already the transverse area of the exit of the hole in mm2 and the apparatus is constructed in such a way that the droplets are expelled from the spray head at a flow rate of at least 0.5 grams per second and have a relationship between the load and mass of minus +/- 1 x 10-4 C / kg.
