Chromosome-scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1
Rivarola, Maximo Lisandro; Conte, Claudia Alejandra; Berube, Pierre; Chen, Shu-Huang; Giardini, Maria Cecilia; Scannapieco, Alejandra Carla; Milla, Fabian Horacio; Soria, Maria Celeste; Russo, Romina Maria; Wulff, Juan Pedro; Djambazian, Haig H.; Pomar, Rolando R.; Handler, Alfred M.; Bourtzis, Kostas; Ragoussis, Ioannis; Lanzavecchia, Silvia Beatriz (Wiley, 2025-10)Anastrepha fraterculus is a cryptic species complex with at least eight morphotypes distributed across the Americas. Among them, A. fraterculus sp.1, present in Argentina, is a major pest impacting fresh fruit production. ... -
Exploring the molecular differentiation of sex chromosomes in Anastrepha fraterculus sp. 1 using comparative genomic hybridization (CGH)
Giardini, Maria Cecilia; Milla, Fabian Horacio; Conte, Claudia Alejandra; Lanzavecchia, Silvia Beatriz; Nieves, Mariela (Springer, 2025-02)Background: The South American fruit fly Anastrepha fraterculus sp. 1 belongs to a cryptic species complex with only a single morphotype present in Argentina, which possess polymorphisms in the sex chromosomes, identified ... -
Geographic distribution of sex chromosome polymorphism in Anastrepha fraterculus sp. 1 from Argentina
Giardini, Maria Cecilia; Nieves, Mariela; Scannapieco, Alejandra Carla; Conte, Claudia Alejandra; Milla, Fabian Horacio; Schapovaloff, Maria Elena; Frissolo, Maria Soledad; Remis, Maria Isabel; Cladera, Jorge Luis; Lanzavecchia, Silvia Beatriz (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. ... -
Molecular characterization of Apis mellifera colonies from Argentina: genotypic admixture associated with ecoclimatic regions and apicultural activities
Agra, Marcelo Nicolás; Conte, Claudia Alejandra; Corva, Pablo Marcelo; Cladera, Jorge Luis; Lanzavecchia, Silvia Beatriz; Palacio, María Alejandra (Wiley Online Library, 2018-08)The European honeybee, Apis mellifera L. (Hymenoptera: Apidae), is considered as a main contributor to pollination of important crops and to honey production. Originally, beekeeping in Argentina was performed in an extended ... -
Molecular detection of reproductive symbionts and parthenogenesis experiments in Tuta absoluta from Argentina: facing potential for sustainable and specific pest control strategies
Cagnotti, Cynthia Lorena; Conte, Claudia Alejandra; Kramar, Jacqueline; Lanzavecchia, Silvia Beatriz; Lopez, Silvia Noemi (Wiley, 2023-06-07)Tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a key pest of tomato crops. Specific and environmentally friendly control strategies against this pest, such as the sterile insect technique (SIT), ... -
Preliminary genome assembly of the Wolbachia endosymbiont of the South American fruit fly, Anastrepha fraterculus sp. 1.
Conte, Claudia Alejandra; Rivarola, Maximo Lisandro; Gonzalez, Sergio Alberto; Russo, Romina Maria; Scannapieco, Alejandra Carla; Wulff, Juan Pedro; Handler, Alfred M.; Ragoussis, Ioannis; Segura, Diego Fernando; Bourtzis, Kostas; Lanzavecchia, Silvia Beatriz (MDPI, 2025-04)Wolbachia sp., an alpha-proteobacterium associated with reproductive phenotypes, has been described with a high prevalence in the South American fruit fly, Anastrepha fraterculus (Diptera: Tephritidae). Two Wolbachia ... -
Stimulus-specific gene expression profiles associated with grooming behavior and Varroa destructor resistance in honey bees
Russo, Romina Maria; Pietronave, Hernan Pablo; Conte, Claudia Alejandra; Liendo, María Clara; Basilio, Alicia Mabel; Lanzavecchia, Silvia Beatriz; Scannapieco, Alejandra Carla (Frontiers Media, 2024-07)Grooming behavior is one of the mechanisms of social immunity in Apis mellifera. This behavior has been proposed as an active strategy of honey bees to restrain the population growth of the ectoparasitic mite Varroa ... -
Symbionts do not affect the mating incompatibility between the Brazilian-1 and Peruvian morphotypes of the Anastrepha fraterculus cryptic species complex
Devescovi, Francisco; Conte, Claudia Alejandra; Augustinos, Antonios A.; Cancio Martinez, Elena I.; Segura, Diego Fernando; Caceres, Carlos; Lanzavecchia, Silvia Beatriz; Bourtzis, Kostas (Springer Nature, 2019-12)The South American fruit fly, Anastrepha fraterculus, is clearly undergoing a speciation process. Among others, two of their morphotypes, the Brazilian-1 and Peruvian, have accumulated differences in pre- and post-zygotic ... -
Transcriptome analysis of Anastrepha fraterculus sp. 1 males, females, and embryos: insights into development, courtship, and reproduction
