TI  - Comparison of two sampling methods for domestic populations of Triatoma infestans 
      in north-west Argentina.
PG  - 238-42
AB  - In mud-and-thatch houses of Santiago del Estero Province, north-west Argentina, 
      where no insecticides had been sprayed officially to control domestic 
      infestations of the Chagas disease vector Triatoma infestans (Klug) (Hemiptera: 
      Reduviidae), two knockdown (KD) insecticidal collection procedures were compared 
      with the standard flush-out (FO) method for sampling T. infestans. Bugs were 
      collected by FO using 0.2% tetramethrin in bedrooms of (1) 41 houses of Amama 
      village employing 1 man-hour of capture effort per house, and (2) 19 houses of 
      Trinidad and Mercedes villages employing 4 man-hours/house. From the same houses, 
      2-5 days after the manual FO collection, bugs were collected by KD 
      indoor-spraying of deltamethrin 25 mg a.i./m2 in Amama, or burning of one 
      gamma-HCH (= gamma-BHC) fumigant tablet 3.1 g of gamma-isomer) per bedroom in 
      Trinidad and Mercedes. The majority of infestations were detected by both 
      methods, the proportion of positive houses being 81% at Amama and 95% at the 
      other villages. Although the FO method was more sensitive, at least because it 
      was applied first, the KD method detected infestations in 25% of houses where 
      bugs were not found by FO. Bug densities estimated by FO or by subsequent KD in 
      each house were significantly correlated: r = 0.795 for deltamethrin; r = 0.882 
      for gamma-HCH. Compared with FO collections of T. infestans large stages, i.e. 
      adults plus fourth and fifth instar nymphs, the KD catch averaged 0.88 x with 
      deltamethrin and 0.57 x with gamma-HCH, regardless of the apparent population 
      density of bugs per house. However, the KD method has practical advantages of 
      speed and standardization.
