“…In the case of T. confusum , close to 100% mortality occurred after 14 days of exposure to 2 ppm in electrostatic powder, but this level of kill was only achieved by 4 ppm in the conventional formulation. All the above data are in agreement with the results reported from previous studies, which demonstrate that using electrostatic charges to improve delivery of certain active ingredients increases their efficacy and at the same time reduces the concentration of pesticide required …”

“…equivalent to conventional spraying. Gaunt et al. (2003) demonstrated that electrostatically charged sprays of bioallethrin and bioresmethrin could be used in the domestic environment to increase the knockdown of houseflies Musca domestica (Diptera, Muscidae) compared with conventional sprays.…”

Entostat TM is an electrostatically charged wax powder that is used as a carrier particle in novel delivery systems for contaminating target insect pests with insecticides, biologicals or pheromones. Here, the adhesion of two forms of Entostat to the Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) was examined, and the adhesion of Entostat to live and dead medflies was compared. From controlled contaminations of medflies, it was shown that live medflies acquired larger quantities of Entostat than dead medflies, which could be due to the electrostatic charge shown to be carried by live insects. Air-milled Entostat (7.59 lm mean diameter) adhered in larger quantities to medflies than pestle and mortar-ground Entostat (9.17 lm mean diameter). Exposing medflies to different quantities of Entostat affected the initially adhering quantity but did not alter the proportion of powder retained over time. Medfly males contaminated with air-milled Entostat were shown to transfer small quantities to females during mating. This documentation of secondary powder transfer underscores the potential for using slow-acting killing agents on the basis of this delivery system.

“…Equations (16)- (18) are only valid for one of three possible situations (e.g., C 2dt > C 3dr ), which occur when the surface of the ring electrode is much smaller than the target surface. As a consequence of the above-mentioned remark, there may be some electrode configurations in which charge induced in a 2-electrode system is higher than charge induced with the induction method in a 3-electrode system for the same applied voltage.…”

“…Charging of aerosol particles is widely used in many technological processes [1][2][3][4]. Among the most common applications, one can mention agriculture (e.g., pesticide application and artificial pollination) [5][6][7][8][9], medicine (e.g., inhalation medications) [10,11], industry (e.g., painting, xerography, and food industries) [12][13][14][15], and others (e.g., thin film deposition, cosmetology, insecticide spraying) [16][17][18]. The use of electroaerosols improves the efficiency of a given process, for example providing more uniform object coverage and increasing the coating efficiency [19][20][21].…”

The charging process of water droplets in different electrification systems using empirical and numerical analysis is described. A simplified model based on capacitance distribution is proposed. The results of the experimental studies and numerical calculations enable comparison of the induction and conduction charging methods in terms of the droplet charging level, described by the Q/m parameter. Research findings indicate that the conduction method in a 3-electrode system is the most effective among all the considered methods. It has been also shown that the application of a 2-electrode system under certain conditions provides greater Q/m parameter values in comparison to the system with three electrodes using the induction method. The research results can be used to develop charging systems (e.g., nozzles) that produce streams with electrically charged liquid particles.
