APPD may also have applications in insect control. A positive correlation was found between exposure time to APPD and mortality of western flower thrips, Frankliniella occidentalis (Pergande); tobacco thrips, Frankliniella fusca (Hinds); Asian tiger mosquito, Aedes albopictus (Skuse); twospotted spider mite, Tetranychus urticae Koch; and German cockroach, Blattella germanica (L.), with the level of mortality also increasing with time after treatment. Cockroaches exposed to APPD for 60, 90, 120, and 180 s lost on average 7.5 ± 0.8, 8.1 ± 0.6, 8.7 ± 0.4, and 10.1 ± 1.1 (±1 SEM) mg of water weight, respectively, which was an increase over that of the controls. The metabolic rate of cockroaches exposed to plasma for 180 s increased from 0.79 ± 0.03 to 1.07 ± 0.04 ml of oxygen consumed mg-cockroach−1 h−1 at standard temperature and pressure. The level of cuticular hydrocarbons identified by electron impact gas chromatography-mass spectrometry were not significantly affected by plasma exposure in the green peach aphid, Myzus persicae (Sulzer), German cockroach, and citrus mealybug, Planococcus citri (Risso), except for a reduction in n-tritriacontane in the latter. However, changes in the behavior of cockroaches after plasma exposure, including the loss of photo-, vibro-, and thigmotropic responses, inability to right themselves, and hyperexcitatory symptoms, suggest that the site of action of APPD in insects is the nervous and/or neuromuscular system.}, number={1}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Donohue, KV and Bures, BL and Bourham, MA and Roe, RM}, year={2006}, month={Feb}, pages={38–47} }

The efficacy of the treatment, represented as percent mortality, is reduced when the aphids reside on tobacco leaves. The reduction in treatment appears to be the result of streamer formation on the leaves. Although the streamer formation has reduced the treatment for aphids on tobacco leaves under our experimental conditions, control of insects such as lice and fleas that reside on alternative substrates can benefit from dielectric barrier discharge (DBD) treatment. Alternative conditions for the generation of DBD may be possible for insect control on plants.}, number={2}, journal={IEEE TRANSACTIONS ON PLASMA SCIENCE}, author={Bures, BL and Donohue, KV and Roe, RM and Bourham, MA}, year={2005}, month={Apr}, pages={290–291} }

In this study, the nonwoven fabric Sontara®, commonly used for surgical gowns, is treated with antimicrobial finishes and a plasma containing fluorocarbon gas. Treated samples are evaluated for changes in physical and functional characteristics. The plasma treatment does not alter the weight, thickness, stiffness, air permeability, and breaking strength and elongation. Plasma-treated and water-repellent Sontara samples show higher blood and water resistance compared to other treatments. Plasma-treated samples also show a zone of inhibition for Staphylococcus aureus, thus providing a barrier against microbes. There is no zone of inhibition for the water repellent Sontara, untreated, and wet control samples. This implies that the nonwoven fabric treated with plasma can provide a better barrier against microbes than commonly available surgical gown fabric with a fluorocarbon finish. }, number={12}, journal={TEXTILE RESEARCH JOURNAL}, author={Virk, RK and Ramaswamy, GN and Bourham, M and Bures, BL}, year={2004}, month={Dec}, pages={1073–1079} }

The fibers were treated for 0, 0.5, 1, 1.5, and 2 min. The surfaces of the fibers treated with He + O2 plasma were etched and micro-cracks were formed. XPS analysis showed a 65ndash213% increase in oxygen content on the surfaces of all plasma-treated fibers, except for the 1.5 min group. An increase in the concentration of C—O and the appearance of C=O bonds on the surfaces of plasma-treated fibers were observed. In the micro-bond test, He + O2 plasma-treated groups had a 65–104% increase in interfacial shear strength over that of the control. The tensile strength of the fibers was either unchanged or decreased by 10–13% by the plasma treatments.}, number={4}, journal={JOURNAL OF ADHESION SCIENCE AND TECHNOLOGY}, author={Qiu, Y and Hwang, YJ and Zhang, C and Bures, BL and McCord, M}, year={2002}, pages={449–457} }
