AB  - The efficacy of untreated and alphacypermethrin-treated high density polyethylene 
      (HDPE) mesh against Culicoides biting midges (Diptera: Ceratopogonidae) was 
      determined using Onderstepoort downdraught black light traps and a contact 
      bioassay. Three traps were operated overnight in four replicates of a 3x3 
      randomised Latin square design near horses under South African field conditions. 
      Both the untreated and alphacypermethrin-treated HDPE mesh significantly (P<0.05) 
      reduced the numbers of Culicoides midges, predominantly Culicoides (Avaritia) 
      imicola Kieffer, collected in the light traps by 4.2 and 7.2 times, respectively. 
      A repellent effect of the alphacypermethrin-treated mesh was not confirmed 
      because the number of midges collected in the light traps with untreated and 
      alphacypermethrin-treated HDPE mesh was not significantly different (P=0.656). 
      Bioassay of the insecticidal contact efficacy indicated median C. imicola 
      mortality of 100% from 30 and 10 min following exposure to the 
      alphacypermethrin-treated HDPE mesh for 1 or 3 min, respectively. In the 
      bioassay, mortality was significantly higher (P=0.016) at 5 min post exposure in 
      the midges exposed to the alphacypermethrin-treated mesh for 3 min (74.8%) 
      compared to the 1 min exposure group (59.5%). The HDPE mesh could be used to 
      reduce exposure of housed animals to Culicoides midges, specifically C. imicola, 
      and viruses transmitted by these midges. Mesh treated with alphacypermethrin had 
      the additional benefit of a rapid insecticidal effect on C. imicola.
