Factors affecting allele frequencies of the alcohol dehydrogenase (Adh) during colonization of natural Bactrocera oleae (Gmelin) populations were investigated. The degree of implication of adult and larval diet antimicrobials to the drastic selection of the Adh-I allele observed under artificial rearing was examined using insects from natural populations. Biological indicators such as pupal recovery and adult emergence are differentially affected when larvae of the 3 homozygous Adh allele strains are reared on diet not containing specific antimicrobial agents. Screening with 6 antimicrobial agents revealed differences in the microflora between the 3 homozygous Adh allele strains. The results presented herewith indicate that antimicrobials play a key role to the selection end-effect, interfering with the equilibrium between naturally and non-naturally occurring microorganisms, and their insect host.
