| effect of soil temperature and moisture on survival and infectivity of metarhizium anisopliae to four tephritid fruit fly puparia. | the infectivity of 4 isolates of metarhizium anisopliae to puparia of ceratitis capitata treated as late third-instar larvae in unsterilized soil was investigated in the laboratory under controlled temperature and moisture. at 20-30 degrees c, mortality in puparia was highest at water potential of -0.1 and -0.01 mega pascal (mpa) and lowest at water potential of -0.0055 and -0.0035 mpa in all the isolates. in wetter soil however, isolates icipe 20 and 60 caused significantly higher mortality tha ... | 2003 | 12788285 |
| assessing the risk of invasion by tephritid fruit flies: intraspecific divergence matters. | widely distributed species often show strong phylogeographic structure, with lineages potentially adapted to different biotic and abiotic conditions. the success of an invasion process may thus depend on the intraspecific identity of the introduced propagules. however, pest risk analyses are usually performed without accounting for intraspecific diversity. in this study, we developed bioclimatic models using maxent and boosted regression trees approaches, to predict the potential distribution in ... | 2015 | 26274582 |
| description of third instar larvae of ceratitis fasciventris, c. anonae, c. rosa (far complex) and c. capitata (diptera, tephritidae). | third instar larvae of members of the ceratitis far complex, including ceratitis fasciventris (bezzi), ceratitis anonae graham, and ceratitis rosa karsch are described and compared with those of ceratitis capitata (wiedemann). diagnostic characters, such as presence vs. absence of a secondary tooth on the mandibles, previously used to separate ceratitis capitata from ceratitis rosa, are shown to vary in each species. significant variation in diagnostic morphological characters among populations ... | 2015 | 26798272 |
| an integrative approach to unravel the ceratitis far (diptera, tephritidae) cryptic species complex: a review. | this paper reviews all information gathered from different disciplines and studies to resolve the species status within the ceratitis far (ceratitis fasciventris, ceratitis anonae, ceratitis rosa) complex, a group of polyphagous fruit fly pest species (diptera, tephritidae) from africa. it includes information on larval and adult morphology, wing morphometrics, cuticular hydrocarbons, pheromones, microsatellites, developmental physiology and geographic distribution. the general consensus is that ... | 2015 | 26798270 |
| analyses of volatiles produced by the african fruit fly species complex (diptera, tephritidae). | ceratitis fasciventris, ceratitis anonae and ceratitis rosa are polyphagous agricultural pests originating from the african continent. the taxonomy of this group (the so-called ceratitis far complex) is unclear. to clarify the taxonomic relationships, male and female-produced volatiles presumably involved in pre-mating communication were studied using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (gc×gc-tofms) followed by multivariate analysis, and gas ch ... | 2015 | 26798269 |
| evaluating mating compatibility within fruit fly cryptic species complexes and the potential role of sex pheromones in pre-mating isolation. | the study of sexual behavior and the identification of the signals involved in mate recognition between con-specifics are key components that can shed some light, as part of an integrative taxonomic approach, in delimitating species within species complexes. in the tephritidae family several species complexes have received particular attention as they include important agricultural pests such as the ceratitis fasciventris (bezzi), ceratitis anonae (graham) and ceratitis rosa karsch (far) complex ... | 2015 | 26798257 |
| resolving cryptic species complexes of major tephritid pests. | an fao/iaea co-ordinated research project (crp) on "resolution of cryptic species complexes of tephritid pests to overcome constraints to sit application and international trade" was conducted from 2010 to 2015. as captured in the crp title, the objective was to undertake targeted research into the systematics and diagnostics of taxonomically challenging fruit fly groups of economic importance. the scientific output was the accurate alignment of biological species with taxonomic names; which led ... | 2015 | 26798252 |
| resolution of three cryptic agricultural pests (ceratitis fasciventris, c. anonae, c. rosa, diptera: tephritidae) using cuticular hydrocarbon profiling. | discrimination of particular species within the species complexes of tephritid fruit flies is a very challenging task. in this fruit-fly family, several complexes of cryptic species have been reported, including the african cryptic species complex (far complex). cuticular hydrocarbons (chcs) appear to be an excellent tool for chemotaxonomical discrimination of these cryptic species. in the present study, chc profiles have been used to discriminate among three important agricultural pests from th ... | 2014 | 24896539 |
| molecular evaluation of nominal species in the ceratitis fasciventris, c. anonae, c. rosa complex (diptera: tephritidae). | ceratitis fasciventris, c. anonae and c. rosa form a complex of economically important fruit fly pests infesting a variety of crops in african countries. hitherto only adult males of these species can be distinguished easily by morphological characters. other stages cannot, and for some taxa the taxonomic interpretation and species boundaries remain unclear. in order to clarify phylogenetic relationships and taxonomic status of these species, sequences of mitochondrial (16s, coi, nd6) and nuclea ... | 2008 | 18502154 |
| population genetics of the potentially invasive african fruit fly species, ceratitis rosa and ceratitis fasciventris (diptera: tephritidae). | a set of 10 microsatellite markers was used to survey the levels of genetic variability and to analyse the genetic aspects of the population dynamics of two potentially invasive pest fruit fly species, ceratitis rosa and c. fasciventris, in africa. the loci were derived from the closely related species, c. capitata. the degree of microsatellite polymorphism in c. rosa and c. fasciventris was extensive and comparable to that of c. capitata. in c. rosa, the evolution of microsatellite polymorphism ... | 2004 | 14871371 |
| wing morphometrics as a possible tool for the diagnosis of the ceratitis fasciventris, c. anonae, c. rosa complex (diptera, tephritidae). | previous attempts to resolve the ceratitis far complex (ceratitis fasciventris, ceratitis anonae, ceratitis rosa, diptera, tephritidae) showed contrasting results and revealed the occurrence of five microsatellite genotypic clusters (a, f1, f2, r1, r2). in this paper we explore the potential of wing morphometrics for the diagnosis of far morphospecies and genotypic clusters. we considered a set of 227 specimens previously morphologically identified and genotyped at 16 microsatellite loci. sevent ... | 2015 | 26798274 |
| cryptic diversity and gene flow among three african agricultural pests: ceratitis rosa, ceratitis fasciventris and ceratitis anonae (diptera, tephritidae). | the 'ceratitis far complex' is a species complex of african fruit flies (diptera, tephritidae) including the major agricultural pest ceratitis rosa and the morphologically similar ceratitis fasciventris and ceratitis anonae. to resolve their intra- and interspecific genetic relationships and to estimate gene flow within this complex, we surveyed allelic variation at 16 microsatellite loci in 27 african populations of the three morphospecies. interpopulation genetic distances and individual bayes ... | 2013 | 23506441 |
| the chromosomes and the mitogenome of ceratitis fasciventris (diptera: tephritidae): two genetic approaches towards the ceratitis far species complex resolution. | ceratitis fasciventris is a serious agricultural pest of the tephritidae family that belongs to the african ceratitis far species complex. species limits within the far complex are obscure and multidisciplinary approaches have attempted to resolve phylogenetic relationships among its members. these studies support the existence of at least three additional species in the complex, c. anonnae, c. rosa and c. quilicii, while they indicate the presence of two structured populations (f1 and f2) withi ... | 2017 | 28687799 |
