Adh1 first intron polymorphisms in Argentinean populations of Ceratitis capitata
(2010-07)DNA size polymorphisms were utilized in a study of 24 natural populations of Ceratitis capitata Wiedemann (Diptera: Tephritidae) from Argentina. The first intron of alcohol dehydrogenase 1 gene (Adh1) was amplified using ... -
Analysis of the gut bacterial community of wild larvae of Anastrepha fraterculus sp. 1: effect of host fruit, environment, and prominent stable associations of the genera Wolbachia, Tatumella, and Enterobacter
(Frontiers Media, 2022-03)The genus Anastrepha (Diptera Tephritidae) includes some of the most important fruit fly pests in the Americas. Here, we studied the gut bacterial community of 3rd instar larvae of Anastrepha fraterculus sp. 1 through Next ... -
Associative learning of visual cues in the fruit fly parasitoid Diachasmimorpha longicaudata : temporal dynamics and potential consequences on females' fitness
(Wiley, 2024-01)Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) is a generalist larval-prepupal parasitoid of true fruit flies (Diptera: Tephritidae). During host-seeking, females use visual information to locate the ... -
Coexistence between two fruit fly species is supported by the different strength of intra- and interspecific competition
(2018-04)1. Unravelling the strength and modes of interspecific interactions between resident and introduced species is necessary in order to understand the basis of their coexistence or the displacement of the former by the ... -
Complementary Sex Determination in the Parasitic Wasp Diachasmimorpha longicaudata
(Plos One, 2015-03)We studied the sex determination in Diachasmimorpha longicaudata, a parasitoid braconid wasp widely used as biological control agent of fruit pest tephritid flies. We tested the complementary sex determination hypothesis ... -
Cryptic genetic structure in an Argentinian population of Anastrepha fraterculus (Diptera: Tephritidae) evidenced by SSR markers and quantitative traits
(Czech Academy of Sciences, 2019-04)In some regions of Argentina and Brazil, the South American fruit fly Anastrepha fraterculus (Wied.) (Diptera: Tephritidae) causes significant damage to crops. An efficient integrated management program requires knowledge ... -
Cytogenetic analysis of the South American fruit fly Anastrepha fraterculus (diptera:tephritidae) species complex : construction of detailed photographic polytene chromosome maps of the Argentinian af. sp.1 member
(2016)Genetic and cytogenetic studies constitute a significant basis for understanding the biology of insect pests and the design and the construction of genetic tools for biological control strategies. Anastrepha fraterculus ... -
Differences in sperm storage and remating propensity between adult females of two morphotypes of the Anastrepha fraterculus (Diptera: Tephritidae) cryptic species complex
(Cambridge University Press, 2014-06)The South American fruit fly, Anastrepha fraterculus, is a complex of cryptic species composed of at least seven morphotypes. Some of them, such as the Peruvian and Brazilian 1 morphotypes (which include Argentinean ... -
Direct and indirect host-related volatile compounds attract a fruit fly parasitoid, Diachasmimorpha longicaudata
(Wiley, 2024-02)Fruit fly pests (Diptera: Tephritidae) are a serious problem for fruit production and for local and international trade. Biological control is increasingly included as a pest control tool within integrated pest management ... -
Dynamics of genetic variability in Anastrepha fraterculus (Diptera: Tephritidae) during adaptation to laboratory rearing conditions
(BioMed Central, 2014)Background: Anastrepha fraterculus is one of the most important fruit fly plagues in the American continent and only chemical control is applied in the field to diminish its population densities. A better understanding ... -
Evaluating mating compatibility within fruit fly cryptic species complexes and the potential role of sex pheromones in pre-mating isolation
(Pensoft Publishers, 2015-11)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 ... -
Geographic distribution of sex chromosome polymorphism in Anastrepha fraterculus sp. 1 from Argentina
(BioMed Central, 2020-12)Background Anastrepha fraterculus is recognized as a quarantine pest in several American countries. This fruit fly species is native to the American continent and distributed throughout tropical and subtropical regions. ... -
Host discrimination in the fruit fly parasitoid Diachasmimorpha longicaudata : evidence from virgin female behaviour and egg distribution patterns
(Cambridge University Press, 2021-04)Many parasitoid species discriminate already parasitized hosts, thus avoiding larval competition. However, females incur in superparasitism under certain circumstances. Superparasitism is commonly observed in the artificial ... -
Identification of candidate genes associated with host-seeking behavior in the parasitoid wasp Diachasmimorpha longicaudata
(BioMed Central, 2024-02)Background: Diachasmimorpha longicaudata is a hymenopteran fruit fly endoparasitoid. Females of this species find their hosts for oviposition by using complex sensorial mechanisms in response to physical and chemical stimuli ... -
Mate choice confers direct benefits to females of Anastrepha fraterculus (Diptera: Tephritidae)
(Public Library of Science, 2019-06)Exposure to plant compounds and analogues of juvenile hormone (JH) increase male mating success in several species of tephritid fruit flies. Most of these species exhibit a lek mating system, characterized by active female ... -
Mating-induced changes in responses of female Queensland fruit fly to male pheromones and fruit : a mechanism for mating-induced sexual inhibition
(Elsevier, 2021-03)In order to reproduce, female tephritid fruit flies need both mates for fertilization and fruit for oviposition. Virgin females are prone to mating and approach males, attracted by their pheromones. Mated females, however, ... -
Microsatellite markers from the ‘South American fruit fly’ Anastrepha fraterculusa: valuable tool for population genetic analysis and SIT applications
(BioMed Central, 2014-12-01)Background: Anastrepha fraterculus Wiedemann is a horticultural pest which causes significant economic losses in the fruit-producing areas of the American continent and limits the access of products to international markets. ... -
