DIAZ, Cristina; ALVAREZ, Yudelmis; DE ARMAS, Yaxier  and  BISSET, Juan A.. Adaptation of methods for quantification of  the effect of esterase, acetylcholinesterase and glutathione-S-transferase in Blatella germanica (Dictyoptera: Blattellidae). Rev Cubana Med Trop [online]. 2006, vol.58, n.3, pp. 0-0. ISSN 1561-3054.

The resistance mechanisms of Blatella germanica, one of the most important urban plagues worldwide since it is a mechanical vector that houses a number of  highly harmful viruses, fungi, helmints and bacteria were studied.  There are different control methods used against Blattella germanica, with insecticides playing the leading role.  Their uncontrolled application has caused the development of insecticice resistance in this species. This paper adapted biochemical methods to detect the enzymes esterase, acetylcholinesterase and glutathine-S-transferase as posible resistance mechanisms. To this end, all the parameters that  allow finding out if a strain is susceptible or resistant to each mechanism were set.

Keywords : Blatella germanica; adaptation; mechanisms; resistance; insecticides.
