Dorsal Disks on the Abdomens of Aleurodicus Dugesii Males (Homoptera: Aleurodicinae) [Elektronische Daten] [John G. Riemann] Adult males of the whitefly Aleurodicus Dugesii Cockerell have large numbers of dorsal disks located on the dorsal surface of their abdomens. These disks have many cuticular pores and occur above a relatively large lumen into which 1 or possibly more epidermal cells release secretory material. The complex of modified cuticle and epidermal cells appeared essentially similar to those on the dorsal surface of abdomens of adult male greenhouse whiteflies, Trialeurodes vaporariorum (Westwood). Thus, the dorsal disks appear to be widely distributed among whiteflies. The function of the dorsal disks and the nature of the secretory material remains unknown. That the disks are sex limited suggests a role in reproduction. For several reasons, but especially because of a lack of innervation, it is thought unlikely that the dorsal disks function as sensory receptors. © 1996 Entomological Society of America Morphology, Histology, and Fine Structure nationallicence whiteflies nationallicence Aleurodicus dugesii nationallicence morphology nationallicence dorsal disks nationallicence ultrastructure nationallicence Annals of the Entomological Society of America Oxford University Press 89/3(1996-05-01), 405-409 0013-8746 89:3<405 1996 89 aesa https://doi.org/10.1093/aesa/89.3.405 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/aesa/89.3.405 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Riemann John G.
