This work was carried out in orchards of guava progenies, and loquat and peach cultivars, in Monte Alegre do Sul, SP, Brazil, in 2002 and 2003. Guavas and loquats were bagged and unbagged bi-weekly and weekly, respectively, for assessment of the infestation period. Peach was only bagged weekly. The assays started when the fruits were at the beginning of development, but still green. Ripe fruits were taken to the laboratory and placed individually into plastic cups. McPhail plastic traps containing torula yeast were hung from January 2002 to January 2004 to assess the fruit fly population in each orchard, but only the Ceratitis capitata population is here discussed. Five tephritid species were reared from the fruits: Anastrepha bistrigata Bezzi, A. fraterculus (Wiedemann), A. obliqua (Macquart), A. sororcula Zucchi, and C. capitata, in addition to six lonchaeid species: Neosilba certa (Walker), N. glaberrima (Wiedemann), N. pendula (Bezzi), N. zadolicha McAlpine and Steyskal, Neosilba sp. 4, and Neosilba sp. 10 (both species are in the process of being described by P. C. Strikis), as well as some unidentified Neosilba species. Ten parasitoid species were obtained from fruit fly puparia, of which five were braconids: Asobara anastrephae (Muesebeck), Doryctobracon areolatus (Szépligeti), D. brasiliensis (Szépligeti), Opius bellus Gahan, and Utetes anastrephae (Viereck), and five figitids: Aganaspis pelleranoi (Brèthes), Dicerataspis grenadensis Ashmead, Lopheucoila anastrephae (Rhower), Leptopilina boulardi (Barbotin, Carlton and Kelner-Pillaut), and Trybliographa infuscata Diaz, Gallardo and Uchôa. Ceratitis capitata showed a seasonal behavior with population density peaking at the second semester of each year. Anastrepha and Neosilba species remained in the orchards throughout both years.

As moscas-das-frutas estão presentes em todas as regiões do Brasil e são responsáveis por grandes perdas econômicas em pomares comerciais. Este trabalho teve o objetivo de determinar a riqueza de espécies de moscas-das-frutas, suas respectivas plantas hospedeiras e seus parasitoides em municípios da região norte de Mato Grosso. Foram realizadas coletas de frutos de 34 espécies vegetais, de julho de 2016 a novembro de 2017. Os frutos coletados foram acondicionados em recipientes plásticos para observar a emergência das moscas-das-frutas e parasitoides. Foram obtidos 2.709 espécimes de moscas-das-frutas (cinco espécies) e 179 espécimes de parasitoides (três espécies). Este trabalho apresenta os primeiros registros de hospedeiros de moscas-das-frutas para o Mato Grosso. Adicionalmente, os parasitoides Utetes anastrephae Viereck e Asobara anastrephae (Muesebeck) são relatados pela primeira vez no Estado.Palavras-chave: Anastrepha; Ceratitis capitata; Relação tritrófica; Amazônia Meridional. FRUIT FLIES, THEIR HOST PLANTS AND PARASITOIDS IN THE NORTHERN STATE OF MATO GROSSO, BRAZIL ABSTRACT: Fruit flies are present in all regions of Brazil and are responsible for large economic losses in commercial orchards. This work aimed to determine the richness of fruit fly species, their host plants and their parasitoids in municipalities in the northern region of Mato Grosso. We collected fruits from 34 plant species, from July 2016 to November 2017. The collected fruits were packed in plastic containers to observe the emergence of fruit flies and parasitoids. We obtained 2,709 specimens of fruit flies (five species) and 179 specimens of parasitoids (three species). This work presents the first records of hosts of fruit flies for Mato Grosso. In addition, the parasitoids Utetes anastrephae Viereck and Asobara anastrephae (Muesebeck) are reported for the first time in the State.Keywords: Anastrepha; Ceratitis capitata; Tritrophic relationship; Southern Amazon.

The hymenopteran parasitoids of pest species of Tephritidae in Brazil are best known by their most prominent species, members of Braconidae and Figitidae. Species in the less-studied families Diapriidae, Eulophidae and Pteromalidae, which are mostly pupal parasitoids, have been largely neglected and the literature on these groups is sparse and scattered. Therefore, their importance as natural enemies of fruit flies is likely underestimated. Here, we present a parasitoid-host-plant checklist of all diapriids, eulophids and pteromalids that parasitize fruit flies of economic importance in Brazil, namely Anastrepha species and Ceratitis capitata. A compilation of information of the seven species of these parasitoids occurring in Brazil—Coptera haywardi Loiácono and Trichopria anastrephae Lima (Diapriidae), Tetrastichus giffardianus Silvestri (Eulophidae), Pachycrepoideus vindemmiae (Rondani), Spalangia endius Walker, S. gemina Bouček and S. simplex Perkins (Pteromalidae)—including their taxonomic status, general biology, and potential as biocontrol agents, is presented. Additionally, we provide an illustrated key to species, aiming to highlight key morphological features and facilitate identification at species level, stimulating future research on these groups.

Toxic bait is an alternative to manage fruit flies (Tephritidae) in orchards and in wide-area programmes. The mortality caused by different dilutions of spinosad baits on adults of Ceratitis capitata (Wied.) and Anastrepha grandis (Macquart) (Tephritidae) were compared with a hydrolysed protein (BioAnastrepha) and water in laboratory. Females and males of C. capitata and A. grandis were exposed to Success® 0.02CB (GF-120 NF Naturalyte fruit-fly, 0.02% spinosad) diluted in distilled water (v/v) at 1:1.5; 1:4.5; 1:9.0 and 1:18.0. Spinosad dilutions at 1: 1.5 and 1: 4.5 showed similar effects and provided 100% adult mortality 24 hours after exposure to the baits. Anastrepha grandis was more susceptible to spinosad baits than C. capitata. Females of C. capitata were less susceptible to spinosad diluted at 1: 1.5, 1: 4.5 and 1: 90, than C. capitata males and both sexes of A. grandis. The values of lethal times (LT50) varied for the different dilutions of spinosad for both fruit-fly species; however, with different patterns for each species. The LT50 values of the two highest concentrations (1: 1.5, 1: 4.5) of spinosad bait were similar for fruit flies of both sexes of each species, but a significant difference was observed between species, with higher LT50 values for C. capitata. In general, the cumulative mortalities of spinosad baits increased at 240, 360, 480 minutes and 24 hours after exposure. BioAnastrepha was shown to be toxic to both species, especially for A. grandis, killing 82% of females and 72% of males at 24 hours after exposure. Spinosad bait may be used in different dilutions to manage C. capitata and A. grandis, with similar toxicity for the two highest spinosad concentrations.
