Composition of Anastrepha species (Diptera: Tephritidae) in habitats with different levels of anthropogenic activity

Abstract

ResumoComposição das espécies de Anastrepha (Diptera: Tephritidae) em habitats com diferentes níveis de atividade antropogênica. Coletamos espécies de Anastrepha em três áreas (ambiente urbano, estação de pesquisa e agricultura) e comparamos as comunidades por índices faunísticos (dominância, abundância, frequência e constância). A diversidade de espécies foi estimada usando a estatística Q e calculando os índices Shannon, Margalef Pielou e Berger-Parker. A semelhança entre as áreas foi baseada nos coeficientes de Sørensen e Bray-Curtis. As áreas do ambiente urbano e da estação de pesquisa apresentaram maior diversidade e similaridade de espécies de Anastrepha. A composição das espécies diferiu entre as áreas, com predominância de A. fraterculus (Wiedemann, 1830) nas três áreas. Os padrões de distribuição não diferiram depois de ajustar as séries geométricas. A área agrícola era a mais diversificada e mais parecida com a área urbana em termos de abundância. A área urbana e a estação de pesquisa eram as mais diversas e eram semelhantes em composição de espécies de Anastrepha. Apesar de estarem sujeitos a diferentes níveis de perturbação humana, esses resultados sugerem que o padrão de abundância e distribuição de espécies de Anastrepha é semelhante nas três áreas. Palavras-chave: AbstractWe collected Anastrepha species in three areas (urban, research station, agricultural) and compared communities by faunal indices (dominance, abundance, frequency, and constancy). Species diversity was estimated using the Q-statistic and by calculating Shannon, Margalef Pielou and Berger-Parker indices. Similarity among areas was based on Sørensen and Bray-Curtis coefficients. The urban and research station areas presented greater diversity and similarity of Anastrepha species. Species composition differed between areas, with predominance of A. fraterculus (Wiedemann, 1830) in the three areas. Distribution patterns did not differ after adjusting the geometric series. The agricultural area was the least diverse and more closely resembled the urban area in terms of abundance. The urban area and research station were the most diverse, and were similar in composition of Anastrepha species. Despite being subject to different levels of human disturbance, these results suggest that the abundance and distribution pattern of Anastrepha species are similar in all three areas.

Spatio‐temporal co‐occurrence of Anastrepha species in papaya orchards in the state of Espírito Santo, Brazil

“…Dominance of a few fruit fly species is often found in surveys in an agricultural environment (Aluja et al, 1996). These two species have been frequently recorded as dominant in commercial orchards in Brazil (Nascimento & Zucchi, 1981; Dutra et al, 2009; Marsaro Júnior et al, 2013; Oliveira et al, 2017). Both species occur throughout Brazil and are associated with a wide range of host plants (Zucchi & Moraes, 2022).…”

New records of Anastrepha Schiner, 1868 (Diptera, Tephritidae) in an urban forest fragment in Manaus, Amazonas, Brazil

“…Likewise, studies in human-impacted areas may provide important information about the population dynamics of fruit fly species (Uramoto et al 2003(Uramoto et al , 2004(Uramoto et al , 2005. For example, in studies carried out in three different areas (urban, research station, and agricultural), the highest diversity and similarity among several species of Anastrepha were observed in the urban and research-station areas (Oliveira et al 2017).…”

Spatio-temporal distribution, diversity and monitoring of fruit flies (Diptera, Tephritidae) in papaya orchards in the state of Espírito Santo, Brazil

“…The dominance of few fruit fly species is generally common in surveys in an agricultural environment . These species have been recorded as dominant in commercial orchards in Brazil (Dutra et al, 2009;Marsaro Junior et al, 2013;Oliveira et al, 2017). These species are part of a complex of cryptic species with a wide range of hosts .…”
