[faunistic analysis of fruit flies (diptera: tephritidae) in the northern and northwestern regions of rio de janeiro state, brazil]. | this study aimed to characterize the fruit fly populations in three municipalities of the northern region and two municipalities of the northwestern region of rio de janeiro state, brazil, and to evaluate the similarity among their populations. a faunistic analysis was performed from the fruit fly specimens captured in plastic mcphail traps with an aqueous solution of hydrolyzed protein to 5% placed in orchards of guava (psidium guajava l.) and/or other fruits during 26 months. the total of 3,95 ... | 2008 | 18368244 |
species of anastrepha (diptera: tephritidae) captured in a guava orchard (psidium guajava l., myrtaceae) in boa vista, roraima, brazil. | 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 2 ... | 2013 | 24789406 |
diversity of anastrepha spp. (diptera: tephritidae) and associated braconid parasitoids from native and exotic hosts in southeastern bahia, brazil. | we documented fruit fly-host associations and infestation rates over 5 yr in the state of bahia, brazil, by systematically collecting native and introduced fruits in backyard and commercial orchards, experimental stations, and patches of native vegetation. fruit were collected in multiple sites in the southern and southernmost regions of bahia. a total of 942.22 kg from 27 fruit species in 15 plant families was collected throughout this study. of these, 15 plant species from six families were in ... | 2010 | 22546440 |
patterns of inner chorion structure in anastrepha (diptera: tephritidae) eggs. | the inner chorion structure of anastrepha eggs from 16 species of various infrageneric taxonomic groups is described by scanning and transmission electron microscopy. the layers of the chorion, the outer egg membrane, are structurally similar. furthermore, an additional trabecular layer (atl) that exists in some species, together with other characteristics, facilitates the recognition of four patterns of chorion structuring: pattern i, in which the atl layer is absent, is found in anastrepha ami ... | 2017 | 27847335 |
toward an automated identification of anastrepha fruit flies in the fraterculus group (diptera, tephritidae). | in this study, we assess image analysis techniques as automatic identifiers of three anastrepha species of quarantine importance, anastrepha fraterculus (wiedemann), anastrepha obliqua (macquart), and anastrepha sororcula zucchi, based on wing and aculeus images. the right wing and aculeus of 100 individuals of each species were mounted on microscope slides, and images were captured with a stereomicroscope and light microscope. for wing image analysis, we used the color descriptor local color hi ... | 2016 | 27156899 |
