TEN YEARS OF RESEARCH ON FRUIT-FLIES (DIPTERA: TEPHRITIDAE) IN THE STATE OF AMAPÁ: PROGRESS MADE AND FUTURE CHALLENGES

As moscas-das-frutas (Diptera: Tephritidae) estão entre as principais pragas da agricultura mundial, sendo motivo de preocupação especialmente para países tropicais em desenvolvimento, os quais têm na fruticultura um importante componente de sua balança comercial. Esta revisão tem por objetivo compilar informações geradas nos últimos 10 anos sobre moscas-das-frutasno estado do Amapá, com ênfase em distribuição, hospedeiros e parasitoides. Além disso, visa indicar as prioridades de pesquisa para os próximos anos.No estado do Amapá, os estudos com moscas-das-frutas e seus inimigos naturais apresentaram, nos últimos anos, significativo crescimento. Atualmente, além Bactrocera carambolae, estão assinaladas para o Estado 34 espécies de Anastrepha. Anastrepha distincta, Anastrepha coronilli, Anastrepha fraterculus e Anastrepha striata são as espécies mais amplamente distribuídas. Estão assinaladas para o estado 37 espécies vegetais hospedeiras (pertencentes a 19 famílias botânicas) de moscas-das-frutas. Anastrepha striata é espécie mais polífaga, estando associada a 25 hospedeiros. Nove espécies de parasitoides específicos de moscas-das-frutas estão registrados, sendo Doryctobracon areolatuso mais abundante. Apesar do significativo avanço, novos estudos sobre biologia, genética, ecologia, distribuição e dispersão populacional, bem como fatores reguladores dos níveis populacionais são necessários, com vista a desenvolver estratégias de controle menos onerosas com efeitos não nocivos ao ambiente.Palavras-chave: Anastrepha, Bactrocera carambolae, parasitoides, Amazônia.Fruit flies (Diptera: Tephritidae) are among the major pests of agriculture worldwide and a concern especially for tropical developing countries, which have fruit in an important component of its trade balance. This review aims to compile information generated on fruit flies in the last 10 years in the state of Amapá, with emphasis on distribution, hosts and parasitoids. It also seeks to indicate priorities for research for years to come. In the state of Amapá, studies fruit flies and their natural enemies had significant growth in recent years. Currently, besides the Bactroceracarambolae, are indicated for the State 34 Anastrephaspecies. Anastrephadistincta, Anastrepha coronilli, Anastrepha fraterculus and Anastrepha striata are the most widely distributed species. Are referred to the state 37 species (belonging to 19 botanical families) of host fruit flies. Anastrepha striata is the most polyphagous species, being associated with 25 hosts. Nine species of fruit flies parasitoids specific are registered,Doryctobraconareolatus is the most abundant.Despite significant progress, further studies on biology, genetics, ecology, distribution and population dispersion, as well as factors regulating population levels are needed in order to develop control strategies less costly with no harmful effects to the environment.Keywords: Anastrepha; Bactrocera carambolae; parasitoids; Amazon

ÁCAROS (ARACHNIDA: ACARI) ASSOCIADOS AO TAPEREBAZEIRO (Spondias mombin L.) NA AMAZÔNIA BRASILEIRA

This is the first survey of mites associated with hog plum trees in the state of Amapá, Brazilian Amazon. We collected 32 species of mites from 17 families. Among the phytophagous mites, Davisella spondias Reis & Navia (Diptilomiopidae) was the most abundant species. Among predator mites, the family Phytoseiidae presented the highest richness of species.Keywords: richness; predator mites; Tenuipalpus uvae; Davisella spondias.Este é o primeiro levantamento de ácaros associados a Spondias mombin L. no Estado do Amapá, norte do Brasil. Foram coletadas 32 espécies de ácaros pertencentes a 17 famílias. Entre os fitófagos, Davisella spondias Reis & Navia (Diptilomiopidae) foi a espécie mais abundante. Entre os ácaros predadores, a família Phytoseiidae apresentou a maior riqueza de espécies.Palavras-chave: riqueza, ácaros predadores, Tenuipalpus uvae, Davisella spondias

Espécies de Anastrepha (Diptera: Tephritidae) capturadas em pomar de goiabeira (Psidium guajava L., Myrtaceae) em Boa Vista, Roraima, Brasil

The guava fruit (Psidium guajava) is among the most strongly affected by fruit flies in Brazil. In the Brazilian Amazon, 11 species of Anastrepha have been reported in guava orchards to date. This work aimed to identify the species of Anastrepha present in a guava orchard in the municipality of Boa Vista, determine the species infesting the fruits, and identify any parasitoids present. Two McPhail traps with food bait were installed and weekly collections were made between January and December 2008. Fruits were also collected systematically during this period, with a view to determining the association between host plant and tephritid species. Nine species of Anastrepha were identified, in addition to one specimen belonging to a probable new species. Anastrepha striata Schiner, Anastrepha sororcula Zucchi, Anastrepha obliqua (Macquart), and Anastrepha fraterculus (Wiedemann) were the dominant species in the orchard, accounting for 84.8% of all captured individuals. All females collected directly from fruits were A. striata. Doryctobracon areolatus (Szépligeti) was the only parasitoid species obtained. In this work, Anastrepha ethalea (Walker) is reported for the first time in the state of Roraima

Este trabalho foi realizado no município de Itaubal do Piririm, Estado do Amapá, com o objetivo de registrar a ocorrência de moscas-das-frutas, suas plantas hospedeiras e seus parasitóides. Foram coletadas 51 amostras de frutos, de 10 espécies vegetais, totalizando 69,5kg. Foram obtidos 1.169 pupários, dos quais emergiram 568 tefritídeos e 105 parasitóides. Quatro espécies de Anastrepha foram registradas: A. antunesi Lima, A. distincta Greene, A. obliqua Macquart e A. striata Schiner. Os hospedeiros de moscas-das-frutas foram taperebá (Spondias mombin), goiaba (Psidium guajava) e ingá-cipó (Inga edulis), com índices de infestação de 1,3; 0,6 e 10,0 pupários/fruto e de 141,1; 20,7 e 26,5 pupários kg-1 de fruto, respectivamente. Duas espécies de parasitóides da família Braconidae foram obtidas: Doryctobracon areolatus (Szépligeti) e Asobara anastrephae (Muesebeck).<br>The occurrence of fruit flies on three host plants and their parasitoids was registered in Itaubal do Piririm, Amapá State, Brazil.
