Abstract

ABSTRACT: Some species of Lonchaeidae (Diptera) are considered frugivorous and polyphagous pests, and are widely distributed in Neotropical regions. The relationship between a fly and its host plant is important for studies on behavior and distribution of frugivorous flies. The objective of this work was to identify the Lonchaeidae fly species and their host plants in the Cerrado biome, specifically in the state of Piauí, Brazil. Eighty-one adults (33 ♀ and 48 ♂) from the genus Neosilba McAlpine (Lonchaeidae), represented by the species Neosilba inesperata Strikis & Prado, Neosilba pendula Bezzi, and Neosilba zadolicha McAlpine, were collected from fruit samples. Oranges [Citrus sinensis (L.) Osbeck] and guava (Psidium guajava L.) had the highest frequencies of infestation. A Neosilba species was considered a primary invader in orange. These results are the first ones reported of Lonchaeidae species and their host plants in the state of Piauí.

Highlights

Some species of Lonchaeidae (Diptera) are considered frugivorous and polyphagous pests, and are widely distributed in Neotropical regions
The Neosilba species collected were: N. inesperata Strikis & Prado (2009), N. pendula Bezzi (1919) and N. zadolicha McAlpine (1982). These species are widely distributed in Brazil as they have been found in fruit in several Brazilian states (CAIRES et al, 2009; DIAS et al, 2012; LEMOS et al, 2015; RAGA et al, 2015; SOUZA et al, 2008; STRIKIS et al, 2011)
Neosilba species were collected from 10 fruit species from seven botanical families in the Cerrado biome of Piauí

Summary

Introduction

Some species of Lonchaeidae (Diptera) are considered frugivorous and polyphagous pests, and are widely distributed in Neotropical regions. The first studies on Lonchaeidae described its species as secondary pests due to their attack on already infested fruits by Tephritidae (STRIKIS; PRADO, 2005). These studies allow us to know the behavior of these insect pests in Brazil’s atypi‐ cal environments, such as the Cerrado biome, in the state of Piauí, and the Lonchaeidae’s potential to be a primary invader of fruits in these environments.
