The second and third instar larvae, and the pupa of Metacuterebra apicalis (Guérin-Menevilli), are described based on light and scanning electron microscope observations

The morphology and chaetotaxy of the first instar larva of Lutzomyia (Lutzomyia) longipalpis are described based on observations made under scanning electron microscope. Because three-dimensional images were studied, some terminological changes are proposed to give a more realistic description of the positions of the setae. On the larval body, the pairs of setae have the following number: 9 on the head, 12 on the prothorax, 8 on the meso- and metathorax, 6 on the first to eighth abdominal segments, and 8 on the ninth abdominal segment

The fourth instar larva of Lutzomyia (Lutzomyia) longipalpis (Phlebotomidae: Phlebotominae) was studied by scanning electron microscope. Based on three-dimensional observations, the fine structure and setal position (using of setal numeration) of the larva are presented.

Cochliomyia hominivorax and C. macellaria are species that cause primary and secondary myiasis, respectively of medical and veterinary importance in the New World. The male terminalia of both insects show morphological differences that are now described from scanning electron microscope (SEM) observations.

The eggs of Muscina stabulans and Synthesiomyia nudiseta are morphologically described, based on scanning electron microscope (SEM).

The morphology of the male and female of Bunostomum phlebotomum are described based on scanning electron microscope (SEM) observations. The attachment of the worms to the small intestinal mucosa and during the copula were observed. Structures of the bucal capsule and genital organs were also studied.

Based on scanning electron microscope (SEM) estudies, the male genitalia of three species of Ravinia and two species of Chaetoravinia (Diptera: Sarcophagidae, subtribe Raviniina) are described and compared.

The male genitalia of nine species of Sarcophagidae (Diptera) - Goniophyto honsuensis Rohdendorf, 1962, Tricharaea brevicornis (Wiedemann, 1830), Chaetoravinia derelicta (Walker, 1852), Austrohartigia spinigena (Rondani, 1864), Chrysagria duodecimpunctata Townsend, 1935, Boettcheria bisetosa Parker, 1914, Lipoptilocnema lanei Townsend, 1934, L. crispina (Lopes, 1938) and Euboettcheria alvarengai Lopes & Tibana, 1982 - were examined by scanning electron microscope (SEM) and the main morphological features are descirbed.

O ovo de Sarcodexia lambens (Diptera: Sarcophagidae) é descrito a nível de microscopia eletrônica de varredura.

The egg of Sarcodexia lambens (Diptera: Sarcophagidae) is described on the basis of scanning electron microscopy.

As genitálias dos machos de Oxyvinia excisa (Lopes), Oxysarcodexia tornax (Walker), O. fluminensis Lopes, sarcodexia lambens (Wiedemann), Peckia chrysostoma (Wiedemann) e Liopygia ruficornis (Fabricius) foram estudadas com base em fotografias de microscópio de varredura. Alguns detalhes importantes foram evidenciados por este método.

Male genitalia of Oxyvinia exicisa (Lopes), Oxysarcodexia thomax (Walker), O. fluminensis Lopes, Sarcodexia lambens (Wiedemann), Peckia chrysostoma (Wiedemann) and Liopygia ruficornis (Fabricius) were studied based on scanning electron microscope photography. Some important details were evidentiated with this method.

O ovo e a larva de primeiro estágio de Metacuterebra apicalis (Diptera, Cuterebridae) são descritos a nível de microscopia óptica e eletrônica de varredura.

Descriptions are given of the egg and first intar larvar of Metacutereba apicalis (Diptera: Cuterebridae) when viewed by light and scanning electronic microscopes.

The first instar larvae of Sarcodexia lambens (Wiedemann, 1830) and Peckia chrysostoma (Wiedemann, 1830) dissected from females reared in laboratory, are described under scanning electron microscope (SEM).
