Abstract

Two important Italian pest thrips species, Frankliniella occidentalis and Thrips tabaci, reproduce arrhenotokously in field populations with high female-biased sex ratios. However, in the laboratory in F. occidentalis male numbers approached these of females (0.7:1 — males:females), but in T. tabaci no males were produced. The presence of Wolbachia could not be detected in unmated females of laboratory strains of the two thrips species.
