Odorant binding protein (OBPs) transcript levels of E. hippophaecolus in four tissues. A: antennae; F:foot; G: external genitals; L: labipalp. Actin was used as the reference gene to normalize target gene expression. The standard errors are represented by the error bars, different lowercase letters (a, b, c) above the bars denote significant differences at p < 0.05, and different capital letters (A, B) above the bars denote significant differences at p < 0.01
