Diversidade de Parasitóides (Hymenoptera: Braconidae e Figitidae) de larvas frugívoras (Diptera: Tephritidae e Lonchaeidae) na Reserva Florestal Adolpho Ducke, Amazônia Ocidental, Manaus, Brasil

This study aimed to identify parasitoid species of frugivorous larvae and to describe the tritrophic interactions involving wild fruits, frugivorous insects and their natural enemies at Adolpho Ducke Forest Reserve (RFAD) (Manaus, AM, Brazil). Collections were performed in four 1 km2 quadrants in the corners of the RFAD. The wild fruits were collected inside the forest in access trails leading to each collection area and in trails that surrounded the quadrants, up to five metres from the trail on each side. The fruits were placed in plastic containers covered with thin fabric, with a vermiculite layer on the base to allow the emergence of flies or parasitoids. Seven Braconidae species were collected, distributed among Opiinae: Doryctobracon areolatus (Szépligeti, 1911), Utetes anastrephae (Viereck, 1913), and Opius sp., and Alysiinae: Asobara anastrephae (Muesebeck, 1958), Phaenocarpa pericarpa Wharton and Carrejo, 1999, Idiasta delicata Papp, 1969, and Asobara sp. Parasitism rates by braconids and figitids are presented. Doryctobracon areolatus was the most frequent, parasitizing the highest number of fly species, and showing the highest parasitism percentage in larvae feeding on Micropholis williamii fruits. The collected figitids belong to Aganaspis nordlanderi Wharton, 1998 and A. pelleranoi (Brethes, 1924). All 15 tritrophic associations are new records for the Brazilian Amazon region. The RFAD is an important natural reservoir of frugivorous larvae parasitoids

Análise das medidas aerodinâmicas no português brasileiro por meio do Método Multiparamétrico de Avaliação Vocal Objetiva Assistida (EVA) Analysis of aerodynamic measures in Brazilian portuguese through Multiparameter Assessment Method Vocal Objective Assist (EVA)

OBJETIVO: definir medidas aerodinâmicas em falantes do português brasileiro, sem queixas vocais, obtidas pelo programa EVA. MÉTODO: participaram do estudo 20 homens e 20 mulheres, que tiveram suas vozes analisadas. RESULTADOS: os valores médios referentes à pressão subglótica para vozes femininas e masculinas foram, respectivamente: Pressão subglótica= 5,84 hPa e 6,7 hPa, média da intensidade= 79,21 dB e 81,7 dB, média do fluxo oral= 0,09 dm³/s e 0,16 dm³/s, eficiência glótica= 13,87 dB/hPa e 12,78 dB/hPa, eficiência laríngea= 188,08 dB/(hPa.dm³/s) e 97,11 dB/(hPa.dm³/s), resistência laríngea= 96,26 hPa/(dm³/s) e 52,64 hPa/(dm³/s), média da frequência fundamental (F0)= 208,28 Hz e 136,56 Hz e pico da pressão do fluxo oral= 0,093 e 0,098. Houve diferença estatisticamente significante em relação ao gênero para as medidas de média de intensidade, eficiência laríngea, resistência laríngea e média da frequência fundamental. Os valores médios referentes ao fluxo oral para vozes femininas e masculinas foram respectivamente: Pressão subglótica= 6,05 hPa e 6,6 hPa, média da intensidade= 65,50 dB e 66,3 dB, média do fluxo oral= 0,10 dm³/s e 0,13 dm³/s, eficiência glótica= 11,12 dB/hPa e 11,77 dB/hPa, eficiência laríngea= 144,83 dB/(hPa.dm³/s) e 97,89 dB/(hPa.dm³/s), resistência laríngea= 78,98 hPa/(dm³/s) e 61,81 hPa/(dm³/s), média da F0= 222,52 Hz e 139,20 Hz e pico da pressão do fluxo oral= 0,047 e 0,053. CONCLUSÃO: o EVA é um programa ainda novo no Brasil, e a análise de medidas aerodinâmicas, em falantes do português brasileiro, permite a obtenção de valores de referência, possibilitando assim comparações com estudos futuros.<br>PURPOSE: to define aerodynamic measures in Brazilian Portuguese speakers without voice complaints, obtained by the EVA program. METHOD: the study included 20 men and 20 women who had their voices analyzed. RESULTS: the mean values with subglottic pressure for female and male voices were: Subglottic pressure = 5.84 hPa and 6.7 hPa; average intensity = 79.21dB and 81.7dB; oral mean flow = 0.09 dm3/s and 0.16 dm3/s; glottic efficiency = 13.87dB/hPa and 12.78 dB/hPa; laryngeal efficiency = 188.08 dB/(hPa.dm3/s) and 97.11dB/(hPa.dm3/s); laryngeal resistance = 96.26 hPa/(dm3/s) and 52.64 hPa/(dm3/s); mean fundamental frequency (F0) = 208.28 Hz and 136.56 Hz and peak mouth pressure flow = 0.093 and 0.098. There was a statistically significant difference in relation to gender for the measures of average intensity, efficiency, larynx, laryngeal resistance and mean fundamental frequency. The average flow for the oral female and male voices were: subglottic pressure = 6.05 hPa and 6.6 hPa; average intensity = 65.50 dB and 66.3 dB; oral mean flow = 0, 10 dm3/s and 0.13 dm3/s; glottic efficiency = 11.12 dB/hPa and 11.77 dB/hPa; laryngeal efficiency = 144.83 dB/( hPa.dm3/s) and 97.89 dB/( hPa.dm3/s); laryngeal resistance = 78.98 hPa/(dm3/s) and 61.81 hPa/( dm3/s); average F0 = 222.52 Hz and 139.20 Hz and peak pressure oral flow = 0.047 and 0.053. CONCLUSION: EVA is a new program in Brazil, and analysing the aerodynamic measures in Brazilian Portuguese speakers, allows us to obtain reference values, thus allowing comparisons with future studies
