| diversity of flies (diptera: tephritidae and lonchaeidae) in organic citrus orchards in the vale do rio caí, rio grande do sul, southern brazil. | this study was carried out in the counties of montenegro and pareci novo located in the region of the vale do rio cai, rio grande do sul, southern brazil, aiming to determine the fruit fly species of tephritidae and lonchaeidae that occur in organic orchards of sweet orange [citrus sinensis (l.) osb.] cultivar céu, and murcott tangor (citrus reticulata blanco x c. sinensis), during the fruit ripening stages in 2003 and 2004. eight mcphail traps baited with integral grape juice diluted to 25% wer ... | 2006 | 17144140 |
| conserved metallomics in two insect families evolving separately for a hundred million years. | μetal cofactors are required for enzymatic catalysis and structural stability of many proteins. physiological metal requirements underpin the evolution of cellular and systemic regulatory mechanisms for metal uptake, storage and excretion. considering the role of metal biology in animal evolution, this paper asks whether metal content is conserved between different fruit flies. a similar metal homeostasis was previously observed in drosophilidae flies cultivated on the same larval medium. each s ... | 2014 | 25298233 |
| identifying anastrepha (diptera; tephritidae) species using dna barcodes. | molecular identification of fruit flies in the genus anastrepha (diptera; tephritidae) is important to support plant pest exclusion, suppression, and outbreak eradication. morphological methods of identification of this economically important genus are often not sufficient to identify species when detected as immature life stages. dna barcoding a segment of the mitochondrial cytochrome oxidase i gene has been proposed as a method to identify pests in the genus. the identification process for the ... | 2017 | 29202187 |
| biology of anastrepha grandis (diptera: tephritidae) in different cucurbits. | anastrepha grandis (macquart) (diptera: tephritidae) is one of the main pests of cucurbits in brazil. losses occur due to the damage caused to the fruits and the embargo on exports, as a. grandis is considered a quarantine pest in countries that import brazilian cucurbits. this study aimed to evaluate the development of a. grandis in hosts of the cucurbitaceae family. the hosts used were stem squash (cucurbita pepo l.), squash (cucurbita moschata duchesne), chayote [sechium edule (jacq.) swartz] ... | 2015 | 26470226 |
| 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 |
