Fruit flies (Diptera, Tephritidae) and their parasitoids on cultivated and wild hosts in the Cerrado-Pantanal ecotone in Mato Grosso do Sul, Brazil

Abstract

ABSTRACT. Fruit flies (Diptera, Tephritidae) and their parasitoids on cultivated and wild hosts in the Cerrado-Pantanal ecotone in Mato Grosso do Sul, Brazil. Information on frugivorous flies in cultivated or wild host plants and their parasitoids in the Cerrado-Pantanal ecotone in Aquidauana, Mato Grosso do Sul is presented and discussed. Fruit fly samples were collected weekly in specific fruit trees, and McPhail ® traps were installed in the same trees for a period of two years. The fruit flies infested ripe and unripe fruits of Averrhoa carambola L., Schoepfia sp., Psidium guajava L. and Pouteria torta (Mart.) Radlk and mature fruits of Anacardium occidentale L. and Inga laurina (Sw.) Willd. Nineteen fruit fly species were obtained with the combination of sampling methods (collecting fruits and trapping), nine of them obtained with both methods, five found only in fruits and five only in traps. This is the first record of Anastrepha striata Schiner in a species of Sapotaceae, as well as for A. castanea Norrbom and A. daciformes Bezzi in Schoepfia sp. (Olacaceae), and for A. distincta Greene in fruits of P. guajava in the state of Mato Grosso do Sul. Fruit collections simultaneously associated with capture of fruit flies by McPhail traps in the same host plants are essential to understand the diversity of fruit flies and their relationship with hosts and parasitoids. Species of Braconidae and Pteromalidae were recovered, where Doryctobracon areolatus (Szépligeti) was the most abundant parasitoid in larvae of tephritids infesting both cultivated and wild host fruits.

Fruit Fly (Diptera: Tephritidae) Community in Guava Orchards and Adjacent Fragments of Native Vegetation in Brazil

“…In Brazil, the hosts of A. montei are fruits/seeds of some species of Euphorbiaceae, such as Manihot esculenta (cassava) and Jatropha sp., and A. turpiniae infests a wide range of fruits of economic importance in several plant families (Zucchi 2008). The capture of A. montei in the traps hung in orchards was similarly to that found by Taira et al (2013). Other species, such as A. alveata, A. daciformis and A. serpentina were collected exclusively in orchard 1 and have no reported hosts in the semi-arid region of Minas Gerais.…”

Parasitoides (Hymenoptera) De Moscas-Das-Frutas (Diptera: Tephritidae) No Semiárido Do Estado Do Ceará, Brasil

“…A identificação das plantas foi realizada no herbário da UFERSA, pelo botânico Dr. Leandro O. F. Sousa (UFERSA). (BITTENCOURT et al, 2012) e no ecótono Cerrado-Pantanal no Mato Grosso do Sul (TAIRA et al, 2013). Doryctobracon areolatus foi a espécie mais abundante (53,1%) e ocorreu nos municípios de Limoeiro do Norte, Russas e Quixeré (Tabela 2).…”

“…Doryctobracon areolatus foi a espécie mais abundante (53,1%) e ocorreu nos municípios de Limoeiro do Norte, Russas e Quixeré (Tabela 2). Importante ressaltar que, dentre os parasitoides de moscas-das-frutas registrados no Brasil, D. areolatus é a espécie que apresenta a mais ampla distribuição geográfica (SILVA et al, 2010;NICÁCIO et al, 2011;NUNES et al, 2012;TAIRA et al, 2013). As outras duas espécies de braconídeos, O. bellus (2,4%) e U. anastrephae (0,6%), foram menos abundantes e foram registrados apenas em Limoeiro do Norte.…”

“…No centro dessas estratégias de manejo integrado, está o uso de himenópteros parasitoides, considerados por muitos pesquisadores como os mais importantes inimigos naturais das moscas-das-frutas, em diversas partes do mundo . No Brasil, as espécies de parasitoides mais comuns, em diferentes levantamentos realizados, pertencem à família Braconidae (SILVA et al, 2010, NUNES et al, 2012, TAIRA et al, 2013. Contudo, a composição das espécies de parasitoides de uma região pode variar consideravelmente, dependendo de uma série de fatores como: clima, diversidade de moscas-dasfrutas, frutífera infestada, entre outros aspectos.…”

Fruit flies and parasitoids associated with guava in Barbalha, Ceará, Brazil

“…These species were already recorded in the region of Cariri in guavas (Azevedo et al, 2013). Furthermore, Doryctobracon areolatus is the species of widest geographic distribution in Brazil (Taira et al, 2013).…”
