Este espacio incluye artículos en revistas, trabajos en congresos, informes técnicos, tesis y otras contribuciones que reflejan el desarrollo del conocimiento en las distintas disciplinas de las ciencias naturales.
- Las publicaciones del Museo son editadas por el Museo de La Plata desde 1890 hasta la actualidad, con artículos de Antropología, Botánica, Ecología, Geología, Paleontología y Zoología. Comenzaron a publicarse en 1890, de forma casi paralela con Los Anales del Museo. Francisco Pascasio Moreno consideraba que el Museo debía tener sus propias publicaciones constituyéndose como un medio para la difusión de las investigaciones que se realizaban en la institución y sirviendo además como elemento de canje con otros museos, bibliotecas e instituciones del mundo.

Item type:Publication, Exploring multigene families of odorant binding proteins and cytochrome P450 monooxygenases in the stink bug pest complex through comparative transcriptomics(Springer Science and Business Media LLC, 2024-09-03) Dulbecco, Andrea Belén; Moriconi, Débora Elizabeth; Cingolani, María Fernanda; Nieves, Eliana Lorena; Diambra, Luis Aníbal; Pedrini, NicolásThe stink bugs Edessa meditabunda, Piezodorus guildinii, and Diceraeus furcatus (Hemiptera: Pentatomidae) are major pests in the Argentinean core area of soybean production. A detailed molecular genetics comprehension of how these insects perceive odorants and respond to semiochemicals and how they detoxify chemical pesticides and plant compounds are essential to improve their management strategies. We first assembled and compared the transcriptomes from E. meditabunda, P. guildinii, and D. furcatus. Regarding sequence similarity, P. guildinii and D. furcatus are closer to each other than E. meditabunda. Then, we characterized the multigene families of odorant binding proteins (OBPs) and cytochrome P450 monooxygenases (CYP). A total of 29, 38, and 39 unigenes encoding for OBP were obtained in E. meditabunda, P. guildinii, and D. furcatus, respectively, divided into classical OBPs and plus-C OBPs. A total of 72, 63, and 76 unigenes encoding for CYP were found in E. meditabunda, P. guildinii, and D. furcatus, respectively, which were further classified into 24 families and 47 subfamilies. On the other hand, we performed for the first time RNA interference in vivo by dsRNA injection in E. meditabunda, suggesting that this molecular tool can be exploited in future physiological and functional studies in this species.Item type:Publication, Tachinids in conservation biological control of phytophagous Pentatomidae(Springer Science and Business Media LLC, 2024-09-12) Punschke, Eduardo Lujan; Carrizo, Ana Paula; de Vilhena Perez Dios, Rodrigo; Blengino, Franco; Huarte, Facundo; Montero, Guillermo Alberto; Fernández, Celina Ana; Cingolani, María Fernanda; Barakat, María CandelaSeveral stink bugs species constitute an important pest complex in soybean worldwide. Tachinidae parasitoids are an important tool to be exploited in conservation biological control programs. We evaluated parasitism of pentatomids in different periods of their life-history: diapause (late autumn and winter), start of activity (spring) and full activity (late summer and early autumn). During the growing seasons 2017–2018 and 2019–2020, we collected stink bugs from soybean, alfalfa and wheat crops and natural vegetation, of three species (Nezara viridula, Edessa meditabunda and Diceraeus furcatus) and reared them in laboratory until pupal formation and adult emergence of tachinid. We examined the relationship among pentatomid abundance and multiple measures of parasitism: through observation of tachinid eggs externally attached to stink bugs body upon field collection and through further verification of parasitism in the laboratory. We also examined the preference of tachinids regarding host sex. Seven tachinid species were detected. Neobrachelia cf. edessae parasitizing E. meditabunda was recorded for the first time in Argentina. Only in two periods of N. viridula life history (diapause and start of activity period) the presence of tachinid eggs externally attached to the stink bugs cuticle was a reliable estimation of successful parasitism. Parasitism was highest on N. viridula, followed by E. meditabunda and lower on D. furcatus. Parasitism of stink bugs was highest during the start of activity and during diapause. During the full activity period in 2017–2018 male hosts were more parasitized than females. This work provides field results valuable for designing tools for pentatomid conservation biological control programs.Item type:Publication, Entomophagous insects: Predators and parasitoids that shape insect communities and offer valuable tools for insect pest management(Wiley, 2024-04-03) Segura, Diego F.; Wajnberg, Eric; Beukeboom, Leo W.; Cingolani, María FernandaThis special issue comprises papers presented at the 7th International Entomophagous Insects Conference (IEIC7), in Buenos Aires, Argentina, in 2023. Entomophagous insects, which prey on or parasitize other insects, play a pivotal role in ecosystems and are widely utilized as biocontrol agents. This special issue includes two review articles and nine research papers covering diverse subjects such as ecology, physiology, behavior, genetics, chemical ecology, and biological control, which reflects the diversity of topics presented and discussed during the conference.Item type:Publication, Conservation biological control of stink bugs: current knowledge and future perspectives(Springer Science and Business Media LLC, 2024-09-10) Laumann, Raúl Alberto; Cingolani, María FernandaStink bugs (Hemiptera: Pentatomidae) are the main pests of a variety of agricultural crops around the world. Usually, a large amount of hazardous pesticides are used to control them, and biological control exerted by natural enemies represents a promising alternative. The improvement upon natural biological control that is achieved by human interventions, by protecting and promoting crop beneficial invertebrates naturally occurring in the environment, is known as conservation biological control. Enhancing the reproduction, survival, and efficacy of natural enemies of pests involves identifying practices harmful to them and finding alternatives, and also developing actions to actively benefit and promote them. In this Special Issue, we summarize current knowledge that contributes to the development and implementation of tools and protocols for the conservation of stink bugs’ biological control agents. Besides, the information presented in this Special Issue, a solid scientific basis can be decisive for the development of conservation biological control strategies for stink bugs that boosts for the implementation of a more sustainable agriculture, with reduced environmental impact and committed to human well-being.Item type:Publication, Dipteran parasitoids as biocontrol agents(Springer Science and Business Media LLC, 2025-03-17) Cerretti, Pierfilippo; Chirinos, Dorys T.; Ferrer, Francisco; Gaviria Vega, Jackeline; Grenier, Simon; Kondo, Takumasa; Pape, Thomas; Plowes, Robert; Salas, Jorge; Vargas, Germán; Whitmore, Daniel; Dindo, Maria Luisa; Cingolani, María Fernanda; Barakat, María CandelaNumerous studies conducted on a variety of temporal and spatial scales around the world show that dipteran parasitoids can exert effective control over some insect pests. This paper provides an overview of major examples of successful classical and augmentative biological control initiatives, organized by major dipteran families which include parasitoid species (i.e., Tachinidae, Phoridae, Sarcophagidae, Cryptochetidae, Bombyliidae, Syrphidae) and according to different global regions. In addition, examples of unsuccessful attempts at biological control using dipteran parasitoids are discussed, along with potential reasons for these failures. A notable drawback found during our literature review is that many parasitoids and host species are not correctly identified, and information on laboratory and field studies is rather scarce. Reproductive strategies of dipteran parasitoids and host-parasitoid associations need to be better investigated. Expanding the knowledge of these parasitoids is crucial for improving biocontrol strategies, especially against pests for which dipterans are key natural enemies.
