A new apparatus to study behavior of triatomines under laboratory conditions.

A new apparatus is described to study a wide range of behavior in the vectors of Chagas's disease. The device is relatively inexpensive and easy to construct. A wide range of independent variables can be studied, including potential attractants, repellents, blood, and blood products under controlled conditions. Various experimental designs can be used including the investigation of learning and social behavior. The apparatus can also be used for the mass rearing of triatomines. The efficacy of the apparatus is illustrated in experiments on the attraction of odors and on fecundity.
