Abstract

The structure, distribution, and type of sensory hairs on the palptarsus of female Varroa jacobsoni Oudemans were examined by scanning electron and phase contrast microscopy. The two large, peg-like setae with apical pores are chemoreceptor sensilla chaetica. The seven slender, round tipped setae, stained with crystal violet at the hair cuticle, are considered to be the chemoreceptor sensilla trichodea. A number of long hairs that did not stain with crystal violet are trichoid tactile setae. The possible functions of these sensilla were discussed.

Résumé

La structure, la distribution et le type de poils sensoriels sur le palpitarse des femelles de Varroa jacobsoni Oudemans ont été examinés au microscope à balayage et par microscopie en contraste de phase. Les deux grosses soies en forme de piquet avec pores apicaux sont des sensilla chaetica chémoréceptrices. Les sept minces soies au bout arrondi, colorées au crystal violet, sont considérées être des sensilla trichoïdes chémoréceptrices. Certains longs poils qui n’ont pas été colorés par le crystal violet sont des soies tactiles trichoïdes. Les fonctions possibles de ces soies sont discutées.
