Moscas-das-frutas (Diptera: Tephritidae) no Semi-Árido do Rio Grande do Norte: plantas hospedeiras e índices de infestação

Abstract

-Fruit flies were collected in traps and also reared from fruits in the semi-arid of the State

Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera, Tephritidae)

“…Acerola is well-accepted for oviposition, as reported in studies showing its high infestation by C. capitata (Albuquerque et al 2002;Araujo et al 2005;Souza et al 2008). However, unexpectedly, acerola emergence percentage was lower than in other fruits preferred for oviposition.…”

“…These fruits were rarely accepted for oviposition, indicating the possible occurrence of an association between preference and performance among these flies. Recent field data showed that umbu infestation by C. capitata was recorded for the first time in 1999-2000 in Rio Grande do Norte state (Brazil), at a low rate (0.04 pupae/Kg of fruit) (Araujo et al 2005). Yellow mombin was reported as host for C. capitata by ), according Zucchi (2001.…”

“…Compared with other fruits, they received more eggs and provided better immature performance. Although often known as a primary host plant of genus Anastrepha (Araujo et al 2005), guava is also reported as C. capitata host in Brazil (Zucchi 2001) and in other regions of the world (Woods et al 2005). In Brazil, different studies show that guava infestation by C. capitata is lower than by Anastrepha UchoaFernandes et al 2002;Araujo & Zucchi 2003;Corsato 2004).…”

“…These fruits have considerable socioeconomic importance, especially in the Northeast of Brazil, and all of them have had records of infestation by C. capitata (Zucchi 2001;Araujo et al 2005). The fruits were purchased in supermarkets to reduce the possibility of obtaining infested fruits.…”

Moscas-das-frutas (Diptera: Tephritidae) em um pomar de goiabeira, no semiárido brasileiro

“…Na região Norte, Anastrepha striata Schiner é a mais comum (PEREIRA et al, 2010). Nas regiões semiáridas de Minas Gerais (sudeste) e interior do Nordeste, Anastrepha zenildae Zucchi é a espécie predominante (ARAUJO et al, 2005;ALVAREN-GA et al, 2009). No litoral da região Nordeste, A. fraterculus é mais comum .…”
