title: Assessment of Long-Lasting Insecticidal Nets (LLINs) on Vectors and Malaria Transmission in the Commune of Aguegues, Benin.
abstract: BACKGROUND
  To overcome the problems of periodic re-impregnation of mosquito nets and low rates of treatment, the commune of Aguegues was chosen to evaluate the effects of Olyset(®) nets on malaria transmission and against An. gambiae.
  
  
  METHODS
  87 old Olyset(®) nets installed five years ago were identified in the village 'Akpadon'. 10 untreated nets were installed in 10 structures of type "a bedroom and parlour" in the village 'Akodji'. Four rooms without nets were identified in the village 'Donoukpa'. Entomological and epidemiological evaluations were conducted during the May to October 2011. 24 sessions of capture or 2088 men-nights resulted in the capture of 30,608 mosquitoes.
  
  
  RESULTS
  The entrance of anopheles was significantly reduced in the village with Olyset(®) nets. 45% of mosquitoes captured inside rooms with Olyset(®) nets were found dead after 24 hrs of obser-vation. Overall, parasitemia was very low in the treated village (4.52%). 18 (4.64%) cases of malaria fever were from Akpadon with 7.5% positive blade smear, 29 (10.98%) were from Akodji with 8.37% positive blade smear, and 80 (95.23%) come from Donoukpa with 38.09% positive blade smear. The Olyset(®) nets and untreated net were adjusted hemoglobin levels.
  
  
  CONCLUSIONS
  Olyset(®) net had a very high knock down effect and is an alternative in malaria control.
