Identification and characterization of soluble binding proteins associated with host foraging in the parasitoid wasp Diachasmimorpha longicaudata
Wulff, Juan Pedro; Segura, Diego Fernando; Devescovi, Francisco; Muntaabski, Irina; Milla, Fabian Horacio; Scannapieco, Alejandra Carla; Cladera, Jorge Luis; Lanzavecchia, Silvia Beatriz (Plos, 2021-06)The communication and reproduction of insects are driven by chemical sensing. During this process, chemical compounds are transported across the sensillum lymph to the sensory neurons assisted by different types of soluble ... -
Identification of candidate genes associated with host-seeking behavior in the parasitoid wasp Diachasmimorpha longicaudata
Wulff, Juan Pedro; Traverso, Lucila M.; Latorre Estivalis, Jose M.; Segura, Diego Fernando; Lanzavecchia, Silvia Beatriz (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 ... -
Individual precocity, temporal persistence, and task-specialization of hygienic bees from selected colonies of apis mellifera
Scannapieco, Alejandra Carla; Lanzavecchia, Silvia Beatriz; Parreño, María Alejandra; Liendo, María Clara; Cladera, Jorge Luis; Spivak, Marla; Palacio, María Alejandra (2016)Hygienic behaviour is a complex trait that gives Apis mellifera L. resistance against brood diseases. Variability in the expression of hygienic behaviour is evidenced at the colonylevel and is explained by the proportion ... -
Microsatellite markers from the ‘South American fruit fly’ Anastrepha fraterculusa: valuable tool for population genetic analysis and SIT applications
Lanzavecchia, Silvia Beatriz; Juri, Marianela Lucía; Bonomi, Angelica; Gomulski, Ludvik; Scannapieco, Alejandra Carla; Segura, Diego Fernando; Malacrida, Anna; Cladera, Jorge Luis; Gasperi, Giuliano (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. ... -
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), ... -
Phenotypic and genetic characterization of Africanized Apis mellifera colonies with natural tolerance to Varroa destructor and contrasting defensive behavior
Bianchi, Eliana Mariel; Ferrari, Carolina; Aguirre, Natalia Cristina; Filippi, Carla Valeria; Vera, Pablo Alfredo; Puebla, Andrea Fabiana; Gennari, Gerardo Pablo; Rodriguez, Graciela Adriana; Scannapieco, Alejandra Carla; Acuña, Cintia Vanesa; Lanzavecchia, Silvia Beatriz (Frontiers Media, 2023-08-31)Africanized Apis mellifera colonies with promising characteristics for beekeeping have been detected in northern Argentina (subtropical climate) and are considered of interest for breeding programs. Integral evaluation of ... -
Precocious sexual signalling and mating in Anastrepha fraterculus (Diptera: Tephritidae) sterile males achieved through juvenile hormone treatment and protein supplements
Liendo, María Clara; Devescovi, Francisco; Bachmann, Guillermo Enrique; Utges, María E.; Abraham, Solana; Vera, María Teresa; Lanzavecchia, Silvia Beatriz; Bouvet, Juan Pedro; Gomez Cendra, Paula V.; Hendrichs, Jorge; Teal, Peter E. A.; Cladera, Jorge Luis; Segura, Diego Fernando (Cambridge University Press, 2013-02)Sexual maturation of Anastrepha fraterculus is a long process. Methoprene (a mimic of juvenile hormone) considerably reduces the time for sexual maturation in males. However, in other Anastrepha species, this effect depends ... -
Sex chromosomes in mitotic and polytene tissues of Anastrepha fraterculus (Diptera, Tephritidae) from Argentina: a review
Giardini, Maria Cecilia; Milla, Fabian Horacio; Lanzavecchia, Silvia Beatriz; Nieves, Mariela; Cladera, Jorge Luis (Pensoft Publishers, 2015-11)Cytogenetics, which is considered a fundamental tool to understand basic genetic and genomic issues of species, has greatly contributed to the description of polymorphisms both at inter- and intra-specific level. In fact, ... -
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 ... -
