Description of the egg of Anopheles (Anopheles) intermedius (Peryassu, 1908) (Diptera: Culicidae) by scanning electron microscopy

Abstract

The egg of Anopheles (Anopheles) intermedius (Peryassu, 1908) is described and illustrated with scanning electron micrographs. Literature data on An. (Ano.) maculipes (Theobald, 1903) is provided.

Ultramorphological features of the egg of Telmatoscopus albipunctatus (Williston) (Diptera, Psychodidae)

“…Eggs of some other dipterans, such as Anopheles sp., present projections on the interface (ventro-lateral) responsible for the egg floating (Wolf & Guanchun 1996;Forattini et al 1997, Valle et al 1999. This same function is attributed to the volcano-like protuberances described for L. panamensis, which is more abundant in damp microhabitats (Ward & Ready 1975;Almeida et al 2004).…”

Ultramorphological characteristics of Chrysomya megacephala (Diptera, Calliphoridae) eggs and its eclosion

“…To maintain this position these eggs have floats and fringes on the flat face, which prevent the egg inversion in the water (Wolf and Guanchun, 1996;Forattini et al, 1997;Valle et al, 1999).…”

“…Some scanning electron microscope studies have been done with this purpose (Wolf and Guanchun, 1996;Forattini et al, 1997;Valle et al, 1999). In this study, C. megacephala egg ultramorphology was analyzed to describe its structure, generating data for further comparison between different species and genera.…”

Ultrastructure of the eggs of two species of Anopheles (Anopheles) Meigen (Diptera, Culicidae)

“…A female of A. forattinii was collected in Iquitos, Peru. Eggs for SEM micrographs were obtained using the same procedure described by FORATTINI et al (1997). Eggs were allowed 36 hours to embrionate, then 20 eggs from each oviposition were transferred to vials containing Bouin's fixative.…”

“…The present study describes the ultrastructure of the egg of two species of the Arribalzagia Series, A. mediopunctatus and A. costai and compare them with egg of A. forattinii, and with those of morphologically similar species of this series that were also described using scanning electron microscopic (RODRIGUEZ et al 2002;LOUNIBOS et al 1997;FORATTINI et al, 1997).…”
