  • addenda to the insects found in birds nests from the Neotropical Region and Neotropical immigrants in the nearctic Region with a discussion of the probable transmission mechanism of ornithocoris toledoi hemiptera cimicidae
    Zootaxa, 2012
    Co-Authors: Osvaldo Di Iorio, Paola Turienzo
    Abstract:

    The present work adds some records to the insect fauna in birds’ nests from the Neotropical Region and Neotropical im-migrants in the Nearctic Region. Unpublished records of Triatominae (Hemiptera: Reduviidae) prior to 2005 are includedhere, especially the localities of some specimens from the collection of Antonio Martinez. According to new data recentlypublished, the probable transmission mechanism of Ornithocoris toledoi (Hemiptera: Cimicidae) is presented here and discussed.

  • Insects found in birds nests from the Neotropical Region (except Argentina) and immigrant species of Neotropical origin in the Nearctic Region
    Zootaxa, 2009
    Co-Authors: Osvaldo Di Iorio, Paola Turienzo
    Abstract:

    Neotropical birds’ nests have received a great deal of attention because sylvatic species of Triatominae (Hemiptera: Reduviidae) and parasitic flies of the genus Philornis (Diptera: Muscidae) were discovered inside them. Those insects known in birds’ nests from Argentina, the chacoan Region of Bolivia, and the southern portion of Brazil and Uruguay were extensively but not completely summarized by Turienzo & Di Iorio (2007). The present contribution summarizes all insects known to occur in birds’ nests from the Neotropical Region (except for Argentina and the Antarctic Region of adjacent countries), updating Hicks’ catalogues for this part of the world. Regarding birds, the list comprises 172 taxa identified to species (in 38 families), 8 to genus (in 6 families), 6 to family (in 4 families), and 27 birds´nests not identified. Regarding insects of the Neotropical Region, 123 were identified to species (13 Blattaria; 5 Coleoptera; 26 Diptera; 34 Hemiptera; 15 Hymenoptera; 23 Psocoptera; 6 Siphonaptera; 1 Thysanura), 96 to genus (5 Blattaria; 8 Coleoptera; 48 Diptera; 4 Hemiptera; 6 Hymenoptera; 25 Psocoptera), 63 to superfamily, family or subfamily (1 Blattaria; 21 Coleoptera; 10 Diptera; 7 Hemiptera; 14 Hymenoptera; 1 Isoptera; 3 Orthoptera; 5 Psocoptera; 1 Thysanoptera), and 34 to order (6 Blattaria [including 1 Mantodea]; 6 Coleoptera; 3 Diptera; 3 Embioptera; 2 Hemiptera; 3 Hymenoptera; 1 Thysanoptera; 2 Isoptera; 4 Lepidoptera; 1 Orthoptera; 1 Phthiraptera; 2 Psocoptera). Associations of Neotropical insects with birds´nests were extracted from 392 references including original and posterior citations. Some North American species of insects that are Neotropical immigrants are discussed, while a few other had been accidentally introduced in both directions. Synonymies, old combinations, misidentifications, original localities, amounts of insects, and repositories when they were stated, are provided.

  • Toxicity assessment of four insecticides with different modes of action on pupae and adults of Eriopis connexa (Coleoptera: Coccinellidae), a relevant predator of the Neotropical Region
    Environmental Science and Pollution Research, 2016
    Co-Authors: Marilina Noelia Fogel, Marcela Ines Schneider, Federico Rimoldi, Lorena Sabrina Ladux, Nicolas Desneux, Alicia Estela Ronco
    Abstract:

    Pesticides can be toxic to nontarget organisms including the natural enemies of agricultural pests, thus reducing the biodiversity of agroecosystems. The lethal and sublethal effects of four insecticides with different modes of action-pyriproxyfen, teflubenzuron, acetamiprid, and cypermethrin-were evaluated on pupae and adults of Eriopis connexa, an effective predator in horticultural crops. Pupal survival was reduced by pyriproxyfen (26 %) and cypermethrin (41 %). Malformations in adults emerged from treated pupae were observed after acetamiprid (82.7 and 100 % for 100 and 200 mg a.i./l, respectively), pyriproxyfen (48.6 %), and cypermethrin (13.3 %) treatments. A longer mean oviposition time was also observed in adults emerged from pupae treated with cypermethrin. Moreover, the latter insecticide as well as teflubenzuron did not reduce reproductive parameters, whereas females emerged from pyriproxyfen-treated pupae were not be able to lay eggs even when females showed large abdomens. Upon exposure of adults, survival was reduced to approximately 90 % by acetamiprid, but no reduction occurred with pyriproxyfen, teflubenzuron, or cypermethrin though the fecundity at fifth oviposition time of the female survivors was reduced. Pyriproxyfen decreased the hatching at all the oviposition times tested, whereas fertility was reduced in the fourth and fifth ovipositions by teflubenzuron and in the first and third ovipositions by cypermethrin. In conclusion, all four insecticides tested exhibited lethal or sublethal effects, or both, on E. connexa. The neurotoxic insecticides were more harmful than the insect-growth regulators, and pupae were more susceptible than adults. The toxicity of insecticides on the conservation of predators in agroecosystems of the Neotropical Region is discussed.

  • zoonotic blood borne pathogens in non human primates in the Neotropical Region a systematic review
    Pathogenetics, 2021
    Co-Authors: Gabriel Carrillobilbao, Sarah Martinsolano, Claude Saegerman
    Abstract:

    Background: Understanding which non-human primates (NHPs) act as a wild reservoir for blood-borne pathogens will allow us to better understand the ecology of diseases and the role of NHPs in the emergence of human diseases in Ecuador, a small country in South America that lacks information on most of these pathogens. Methods and principal findings: A systematic review was carried out using PRISMA guidelines from 1927 until 2019 about blood-borne pathogens present in NHPs of the Neotropical Region (i.e., South America and Middle America). Results: A total of 127 publications were found in several databases. We found in 25 genera (132 species) of NHPs a total of 56 blood-borne pathogens in 197 records where Protozoa has the highest number of records in Neotropical NHPs (n = 128) compared to bacteria (n = 12) and viruses (n = 57). Plasmodium brasilianum and Trypanosoma cruzi are the most recorded protozoa in NHP. The Neotropical primate genus with the highest number of blood-borne pathogens recorded is Alouatta sp. (n = 32). The use of non-invasive samples for Neotropical NHPs remains poor in a group where several species are endangered or threatened. A combination of serological and molecular techniques is common when detecting blood-borne pathogens. Socioecological and ecological risk factors facilitate the transmission of these parasites. Finally, a large number of countries remain unsurveyed, such as Ecuador, which can be of public health importance. Conclusions and significance: NHPs are potential reservoirs of a large number of blood-borne pathogens. In Ecuador, research activities should be focused on bacteria and viruses, where there is a gap of information for Neotropical NHPs, in order to implement surveillance programs with regular and effective monitoring protocols adapted to NHPs.
