Chaetotaxy and setal morphology of the palps and first tarsi of Phytoseiulus persimilis A.-H. (Acarina: Phytoseiidae)
1974 - Volume: 16 Issue: 4 pages: 583-594
The chaetotaxy and setal morphology of the palp tibia and tarsus and the distal part of the anterior tarsus are described and figured for Phytoseiuliis persimilis A.-H. Long, tapering, pointed setae vvith basal sockets occur on the palp and anterior tarsus, and are presumed to fonction as mechanoreceptors. Also, shorter setae of various forms and tip structures occur on the palp and anterior tarsus; many of these setae resemble known contact chemoreceptor types, and probably also fonction as mechanoreceptors. An olfactory fonction is suggested for some of the setae on the anterior tarsus.
