Entomological study Roberts, Donald R Hoch, Alfred L Peterson, Norman E Pinheiro, Francisco de Paula Controle de Doen?as Transmiss?veis Ecologia Ceratopogonidae Fatores de Tempo Culicidae Brasil (BR) A program of entomological surveillance was conducted for two years (1974-1976) along the Transamazon Highway, Par?, Brazil. Routine collections from human bait were performed to characterize the available habitats by their respective groupings of hematophagous insects most likely to transmit diseases to the colonist populations. A total of 76,804 hematophagous insects were collected from routine surveillance at 12 sites along the highway. Black flies were the dominant daybiting insects in the cleared peridomiciliary habitat. The cleared areas around houses were effective daytime barriers to all the other hematophagous insects. Biting midges were active in the forest during daylight; but peak activity occurred at night, at which time some midges were caught in the peridomiciliary enviromnent as well. Sand flies were rarely collected outside the forest and were mainly night-active. Although mosquitoes were infrequently collected in open areas during daylight, peak nurmbers were collected near houses at night. In comparison, very low numbers were collected indoors (average of 1/man-hr). Only 8 from a total of 64 mosquito species were routinely collected in abundance at all 12 sites. Three of the eight species were codominants in daytime collections on the forest floor, viz., Psorophora albipes (Theobald), Trichoprosopon digitatum (Rondoni) and Wyeomyia aporonoma (Dyar and Knab). Sabethes chloropterus (von Humboldt) and Sa. glaucodaemon (Dyar and Shannon) were dominants in the tree canopy. Anopheles nu?eztovari (Gabaldon) were collected in high frequency and numbers at night in scrub growth near houses. Two other anophelines, An. oswaZdoi(Peryassu) anddn. Ttiannulatus (Neiva and Pinto), also were abundant both day and night in the forest; but only at night in the secondary scrub habitats. The medical importance and pest value of the dominant species, along with that of the other hematophagous insects, is discussed. Based on the vector roles of the insect groups included in this report, and their temporal and spatial distributions, as documented, we believe hunters alongwith forest and field workers were the target populations for the endemic insectborne diseases. This was primarily a result of 1) a general absence at most sites of any endophagic species and 2) the ecological barrier presented by cleared land around the colonists? houses. Realizou-se um programa de estudos entomol?gicos durante dois anos (1974- 1976) em zonas confinantes com a Estrada Transamaz?nica no Par?, Brasil. Recolheram-se amostras com engodos humanos para caracterizar os habitat da regi?o, segundo as suas respectivas agrupa??es de insectos hemat?fagos com maiores probabilidades de transmitir doen?as a povoa??o de colonos. Recolheram-se em total 76.804 insectos hemat?fagos por meio da amostragem comum em 12 lugares pr?ximos da Estrada. As moscas pretas eram os insectos sangradores diurnos que predominavam nos habitat das zonas desocupadas peridomicili?rias. Estas zonas constituiam barreiras eficazes contra os outros insectos hemat?fagos durante o dia. Os mosquitos mostravam-se activos na floresta durante o dia, mas a noite era o momento da sua m?xima actividade e a essa hora apanhavam-se alguns mosquitos tamb?m no ambiente peridomicili?rio. Raras vezes se apanharam moscas da areia fora da floresta: estes insectos mostravam-se principalmente activos de noite. A-pesar de que em muito poucas ocasi?es se apanharam culic?deos nas zonas desocupadas durante o dia, re?niram-se grandes quantidades perto das casas durante a noite. Relativamente, foi muito reduzido o numero capturado dentro das casas (uma m?dia de 1/hora/homem). S? oito do total de 64 esp?cies de mosquitos se conseguiram em abundancia na amostragem comum dos 12 lugares. Tres das oito esp?cies predominavam juntas nas amostras diurnas recolhidas no solo da floresta, que foram: Psorophora albpes(Theobald), Trichoprosopon dzgitatum (Rondoni) e Wyeomykz aporonomu (Dyar e Knab). Sabethes chloroperus (von Humboldt) e S. glaucodaemon (Dyar e Shannon) predominavam na ab?bada florestal. Anopheles nu?eztovari (Gabaldon) conseguiu-se freq?entemente e em n?mero elevado nos matorrais pr?ximos das casas. Outros dois anofelinos, A. oswaldoi (Peryassu) e A. triannulatus (Neiva e Pinto), tamb?m eram abundantes. 2016-09-26T11:49:07Z 2016-09-26T11:49:07Z 1981 Artigo ROBERTS, Donald R. et al.
