BR bristles, BA basiconic, TH thin-walled trichoid, TK thick-walled trichoid, F female and M male, I infected, NI non-infected, D domestic, S sylvatic, and L laboratory-reared. Asterisks represent a significant difference between infected and non-infected insects (P < 0.05*; P < 0.01**; P < 0.001***; – no difference)
