Differential efficiencies of dip-net sampling versus sampling surface-floating pupal exuviae in a biodiversity survey of Chironomidae

Autor: Leonard Charles Ferrington Jr, William P. Coffman

Publikováno v: CHIRONOMUS Journal of Chironomidae Research, Iss 27 (2014)

Relative efficiencies of standard dip-net sampling (SDN) versus collections of surface-floating pupal exuviae (SFPE) were determined for detecting Chironomidae at catchment and site scales and at subfamily/tribe-, genus- and species-levels based on s

Pupal respiratory complex of Tanypus carinatus sublette var. (Diptera: Chironomidae)

Autor: George Carmody, William P. Coffman, Frederick Jay Gottlieb

Publikováno v: International Journal of Insect Morphology and Embryology. 3:147-155

The thoracic respiratory organ of the pupa of the genus Tanypus is usually assumed to lack a plastron element. Little information has appealed in the literature regarding the active site(s) of respiration. However, it has been inferred that the aerop
