Quantitative real-time PCR analysis of relative expression levels of chemosensory proteins (CSPs) from C. nigricornis. A: antennae; H: head (antennae were cut off); L: leg; W: wing; T: abdomen-thorax. The β-actin was used as the reference gene and CnigCSP1 in female antennae as a positive control. The error bars represent the standard error of three independent experiments. Different small letters above bars indicate significant differences among different tissues (P < 0.05). * indicates significant difference between both sexes in the same tissue (P < 0.05), and ns indicates no significant difference
