Faunistic analysis of the species of Anastrepha Schiner (Diptera: Tephritidae) in three municipalities of the state of Roraima, Brazil

Abstract

The purpose of this work was to describe the population patterns of Anastrepha in three municipalities of the state of Roraima, Brazil, via faunistic analysis. Weekly collections were performed from January through December 2008, using McPhail traps containing 5% hydrolysed protein, in domestic orchards in the municipalities of Boa Vista, Bonfim and Pacaraima. We captured 301 females of Anastrepha in Boa Vista, 212 in Bonfim, and 167 in Pacaraima. Boa Vista presented the highest species richness (S = 10) and Pacaraima the lowest (S = 4). Anastrepha striata was the predominant species in Boa Vista (47.18%) and Pacaraima (65.87%), whereas A. obliqua predominated in Bonfim (46.23%). Boa Vista presented the highest Shannon-Wiener diversity index (H' = 1.19) and Margalef index (α = 1.58), and Bonfim presented the highest Pielou's evenness index (J' = 0.69). In Pacaraima the cumulative curves reached stability, confirming that the observed and expected species richness were the same. In the other two municipalities, the curves showed a moderate growth, suggesting that the sampling effort was not sufficient to produce an accurate depiction of species richness. In this study, Anastrepha zernyi is reported for the first time in Roraima.Keywords: Amazon, diversity, faunistic index, fruit flies.

BIODIVERSITY AND POPULATION DISTRIBUTION OF FRUIT FLY (Diptera: Tephritidae) IN DOMESTIC ORCHARDS OF PARAÍBA STATE, BRAZIL

“…Anastrepha fraterculus was the most frequent, dominant and constant species, being present in all localities, followed by A. obliqua, A. sororcula and C. capitata, which were frequent, dominant and constant in certain municipalities studied (Table 1), corroborating several studies involving the faunistic analysis of tephritids, which found the occurrence of two to three dominant species in different regions of Brazil (HUSCH et al, 2012;MARSARO JÚNIOR et al, 2012;ARAUJO et al, 2013).…”

“…Information on the faunistic analysis of tephritids is crucial for understanding the bioecology of these insects in different areas (MARSARO JÚNIOR et al, 2012). Therefore, several studies have been conducted around the world using food traps in order to know the diversity, monitor and/or control tephritids (ORDANO et al, 2013;TAIRA et al, 2013;ALI et al, 2014).…”

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

“…The data analyzed here were obtained mainly from papaya orchards, although probably with some influence from urban and Atlantic forest remnant areas. The maximum richness found here is coherent with fruit fly surveys in tropical areas, which generally do not find richness levels higher than those estimated in this study (Almeida et al, 2019;Marsaro Júnior et al, 2012). The abundance of flies also changed during the study period.…”

Ecological importance of lepidopteran defoliators on eucalyptus plantations based in faunistic and natural enemy analyses

“…Lepidopteran families were grouped in abundance classes according to CIs (Thomazini and Thomazini, 2002;Silva et al, 2011;Marsaro Júnior et al, 2012): ma= very abundant (number of individuals greater than the upper limit of the CI at 1%), abundant (a), common (c), dispersed (d) and rare (r), respectively, with number of individuals between the upper limits of the CI at 5 and 1%, within the CI at 5%, between the lower limits of the CI at 5 and 1%, and under the lower limit of the CI at 1%.…”
