  • EXAMPLE Repelling Aedes aegypti mosquitoes with electric fields using insulated conductor wires
  • the trap and dry ice were placed inside a PVC box (Ixwxh: 61 x61 x 102 cm) that had one opening for an ‘EF window’ (see ‘Electric field (EF) window’). This opening was located 21 .7 cm from the top of the box, 50.8 cm from the bottom of the box, and equidistant from the sides (15.75 cm). Mosquitoes had to pass through this window to get to the bait/trap. Placement of the box in relation to the mosquito net and mosquito release point is shown in FIGS. 5A-5C.
  • the room was programmed on a 12h photoperiod (i.e., 07:00 h lights on; 19:00 h lights off).
  • Room temperature (°C) and relative humidity (RH) were not regulated but monitored with a datalogger (Model No. OM-92-NIST, accuracy: ⁇ 0.3°C and ⁇ 3% RH, Omega, Connecticut, USA) during each experimental run (Table 1). Every morning at 10:00 h (i.e. 23h after release), all mosquitoes were recaptured, and it was noted if they were collected i) outside the PVC box, ii) inside the PVC box but not in the trap, or iii) in the catch bag of the trap.
  • Each EF window frame (outer dimension 29.5x29.5 cm; inner dimensions 24.4x24.4 cm) consisted of a single row of parallel-placed ICWs (insulation: polyvinyl chloride, 14 AWG, 0.36 cm diameter, rated for 600V AC) with alternating polarity (starting and ending with a positively charged ICW). Wires were either placed 2 or 3 cm apart (depending on the experiment, see below) from the center of the wires, which results in distances between ICWs of 1 .64 or 2.64 cm, respectively.
  • aegypti mosquitoes were captured between 11 :00 h -19:00 h, 19:00 h - 07:00 h and 07:00 h - 10:00 h, respectively (FIG. 8). Data from the other experiments is similar.
  • This example introduces a novel approach using insulated conductor wires to generate electric fields that prevent host-seeking female Aedes aegypti from entering spaces.
  • the ICWs used here generated EFs that repelled over 50% of mosquitoes at >3.66kV/cm.
  • Other studies have shown higher repellency of mosquitoes using electric fields.
  • parallel-placed copper plates and aluminum blinds repelled over 90% of Ae.
  • Ae. aegypti host-seeking behaviors mosquitoes exhibited reduced activity during the nighttime hours, when lights were off in the room. Most mosquitoes that passed the EF window were caught before 19:00 h, followed by mosquitoes passing through during the morning hours (7:00 h - 10:00 h). These findings are consistent with their known natural behavior, as Ae. aegypti is a typical daytime (diurnal) biter. Understanding this behavior is important, as in theory the EF technology can be switched on during periods of time when mosquitoes are active, and switched off when mosquitoes are not active, which could benefit energy costs and product lifespan.
  • repellency intuitively may seem low (50-60% in this study compared to >90% in a previous study), it could still significantly impact disease transmission.
  • the repellency values here are between those reported for spatial repellents (SR), which showed low (e.g. 16.4%) to high (e.g. 70%) reductions in malaria mosquito-human contact.
  • the housing improvement toolkit as the conductors can be installed in mosquito entry points (eaves, windows, and/or doors), preventing mosquito entry similar to current technologies such as eave tubes, transfluthrin-treated eave ribbons, screened windows, and doors. Investigating these aspects will not only refine the efficacy of EF technologies but also pave the way for a more equitable and sustainable approach to combating mosquito-borne diseases in resource-limited settings.

Abstract

L'invention concerne des systèmes de répulsion d'insectes qui comprennent au moins une rangée de multiples fils conducteurs isolés (ICW) disposés sensiblement parallèlement les uns aux autres. Les systèmes comprennent également une alimentation électrique connectée fonctionnellement à ladite rangée de multiples ICW. L'alimentation électrique est conçue pour fournir de l'énergie électrique à ladite au moins une rangée de multiples ICW de telle sorte que des particules chargées se déplacent entre les paires voisines d'ICW dans ladite au moins une rangée de multiples ICW lorsque l'énergie électrique est fournie à ladite au moins une rangée de multiples ICW par l'alimentation électrique. L'invention concerne également des procédés et d'autres aspects associés.
