A. Yebakima et al., DETOXIFYING ESTERASES IN CULEX-PIPIENS QUINQUEFASCIATUS FROM THE CARIBBEAN COUNTRIES, Journal of the American Mosquito Control Association, 11(3), 1995, pp. 363-366
Several over-produced esterases confer resistance to organophosphorus
insecticides in the Culex pipiens complex. We describe their distribut
ion in islands and countries of the Caribbean region based on new coll
ections and previous studies, and discuss the need to: 1) undertake DN
A studies to correctly identify the esterase B alleles that are amplif
ied in different regions, and 2) investigate the variability among gen
e copies within each amplification system in order to fully understand
their origin and their evolution through time.
