Previous issue date: 2006-03-17 / Among the dipterans of medic-sanitary interest the blowfly families Calliphoridae
and Sarcophagidae are distinguished. Its occurrence, distribution and predominance in
metropolitans areas are factors of great importance to the Public Health, because the adults are
vectors of pathogens for the man and its larvae attack the man in such a way as animal
domestic servants. The capture of the calliphorid fauna with traps, bait with viscera cool of
chicken, in three distinct ecotypes (agricultural, urban and forest). 31.480 califor?deos
dipterans distributed in the following species had been captured: Chrysomya megacephala
(54,45%), C. putoria (11,18%), C. albiceps (13,63%), Phaenicia eximia (5,90%), P. cuprina
(1,07%), Cochliomyia macellaria would (9,06%), C. hominivorax (0,53%), Hemilucilia
segmentaria would (0,80%), H. semidiaphana (1,40%), Mesembrinella bellardiana (1,24%),
Eumesembrinella sp. (0,51%), Chloroprocta idioidea (0,09%) and P. sericata (0,13%). The
Sinanthropy Index and Seasonal Fluctuation and the Coefficient of Constancy of the species
between the autumn of the 2002 and summer of 2004 had been determined. C. albiceps had
the highest Sinanthropy Index (IS = + 41,7) conferring to this species was has Preference for
Inhabited Areas. Also C. megacephala (IS = +33.01), C. putoria (IS = +25.1), C. hominivorax
(IS = +24.1), C. macellaria would (IS = +21,14), P. cuprina (IS = +18,78), P. eximia (-9,67)
species with Preference for Inhabited Areas and finally H. segmentaria, H. semidiaphana, M.
bellardiana, Eumesembrinella sp., C. idioidea, P. sericata all pertaining to the group,
according to data, that possess Complete Absence in Inhabited Areas (IS = -100). The
microhimenopteran parasitoids are important tools in the biological control of flies of
economic importance that cause damages to the health of human being and other animals.
The captures had occurred between january and december of 2004 in urban, rural and forest
area. 1.528 larvae of C. hominivorax (Coquerel, 1858) had been used as bait, 505 in the urban
one, 556 in agricultural and the 467 in the forested one. The Sinanthropy Index, Coefficient of
Constancy, the risk of parasitism (Odds Ratio) between the areas had been calculated,
prevalence and parasitic intensity. The percentage was 46,6%. Aphaereta laeviuscula
(Spinola, 1851) was captured only in agricultural environment, its indices had been:
Sinanthropy I. = +50, C. constancy =25%, prevalence =0,72% and I. parasitoid =44,5; on the
other hand Nasonia vitripennis (Walker, 1836) was captured in the areas agricultural and
urban and the indices had been: Sinanthropy I. = +98, C. constance =58.3%, Odds Ratio =
IC95% = 0,025 < > 0,27, p<0,05, prevalence= 3,2% and I. parasitoid =7,35. The risk of
parasitism for N. vitripennis in urban areas is high. It was registered the occurrence of A.
laeviuscula as parasite of C. hominivorax in the State of Rio de Janeiro.
Blowfly, Parasitoids, Sinanthropy, Seasonal Variation. / Entre os d?pteros de interesse m?dico-sanit?rio destacam-se as moscas varejeiras
das fam?lias Calliphoridae e Sarcophagidae. Sua ocorr?ncia, distribui??o e predomin?ncia em
?reas metropolitanas s?o fatores de grande import?ncia na Sa?de P?blica, pois os adultos s?o
vetores de pat?genos para o homem e suas larvas atacam tanto o homem como animais
dom?sticos. A captura da fauna califor?dica foi realizada atrav?s de armadilhas, iscadas com
v?sceras frescas de frango, em tr?s ec?topos distintos (rural, urbano e de floresta). Foram
capturados 31.480 d?pteros califor?deos distribu?dos nas seguintes esp?cies: Chrysomya
megacephala (54,45%), Chrysomya putoria (11,18%), Chrysomya albiceps (13,63%),
Phaenicia eximia (5,90%), Phaenicia cuprina (1,07%), Cochliomyia macellaria (9,06%),
Cochliomyia hominivorax (0,53%), Hemilucilia segmentaria (0,80%), Hemilucilia
semidiaphana (1,40%), Mesembrinella bellardiana (1,24%), Eumesembrinella sp. (0,51%),
Chloroprocta idioidea (0,09%) e Phaenicia sericata (0,13%). Foram determinados os ?ndices
de Sinantropia e Flutua??o Sazonal e o Coeficiente de Const?ncia das esp?cies entre o outono
de 2002 e o ver?o de 2004. C. albiceps teve o mais alto ?ndice de Sinantropia (IS= + 41,7)
conferindo a esta esp?cie, a seguinte classifica??o de acordo com Ferreira (1978 e 1983):
esp?cie que tem Prefer?ncia por ?reas Habitadas. Tamb?m C. megacephala (IS= +33,01), C.
putoria (IS= +25,1), C. hominivorax (IS= +24,1), C. macellaria (IS= +21,14), P. cuprina (IS=
+18,78), P. eximia (-9,67) esp?cie com Prefer?ncia por ?reas Habitadas e finalmente H.
segmentaria, H. semidiaphana, M. bellardiana, Eumesembrinella sp. C. idioidea, P. sericata
todas pertencentes aos grupos, segundo os dados obtidos, que possuem Completa Aus?ncia em
?reas Habitadas (IS= -100). Os microhimen?pteros parasit?ides s?o ferramentas importantes
no controle biol?gico de moscas de import?ncia econ?mica e causadora de danos ? sa?de
humana e de outros animais. As capturas ocorreram entre janeiro e dezembro de 2004 em ?rea
urbana, rural e florestal. 1.528 larvas de Cochliomyia hominivorax (Coquerel, 1858) foram
usadas como iscas, 505 na urbana, 556 na rural e 467 na florestada. Foram calculados os
?ndices de Sinantropia, Coeficiente de Const?ncia, o risco (Odds Ratio) de parasitismo entre as
?reas, preval?ncia e intensidade parasit?ria. O percentual de emers?o foi de 46,6%. Aphaereta
laeviuscula (Spinola, 1851), foi capturada apenas em ambiente rural, seus ?ndices foram: I.
sinantropia= +50, C. const?ncia=25%, preval?ncia=0,72% e I. parasit?ria=44,5; j? Nasonia
vitripennis (Walker, 1836) foi capturada nas ?reas rural e urbana e os ?ndices foram: I.
sinantropia= +98, C. const?ncia=58,3%, Odds Ratio= IC95%= 0,025 <?> 0,27, p<0,05,
preval?ncia, =3,2% e I. parasit?ria=7,35. O risco de parasitismo por N. vitripennis em ?reas
urbanas ? alto. Registra-se a ocorr?ncia de A. laeviuscula como parasito de C. hominivorax no
Estado do Rio de Janeiro.
