a
Frequency of cqm1 alleles in Culex quinquefasciatus larvae from four nontreated populations (IPO, JAB, ROD, AZE), as well as one treated population exposed to B. sphaericus (AGU). SS, homozygous for cqm1; SR and RR, heterozygous or homozygous for one of the resistance (r) alleles, respectively; F, allele frequency.
