^*The total number of genes including pseudogenes for Ae. albopictus is shown in parentheses.

^†Numbers derived from this study, Strode et al., 2008 (41), Yan et al., 2012 (31), VectorBase (92), and FlyBase (93).

^‡Cytosolic glutathione-S-transferases only.

^§Numbers derived from Dermauw and Van Leeuwen (94) and the present study.
