We describe the first, to our knowledge, cases of han-tavirus pulmonary syndrome in northeastern Argentina and eastern Paraguay. Andes and Juquitiba (JUQ) viruses were characterized. JUQV was also confirmed in 5 Oligoryzomys nigripes reservoir species from Misiones. A novel Akodon-borne genetic hantavirus lineage was detected in 1 rodent from the Biologic Reserve of Limoy.
در این تحقیق اطلاعاتی در زمینه‌ی پراکنش و رابطه‌ی بین شته‌های یونجه و پارازیتوییدهای آنها در مناطق مختلف یازده استان ایران همراه با کلید شناسایی ارایه می‌گردد. مهمترین شته‌های یونجه عبارت بودند از Therioaphis trifolii maculata (Buckton) و Acyrthosiphon pisum (Harris) و سپس Aphis craccivora Koch و Acyrthosiphon kondoi Shinji. الگوی پراکنش این شته‌ها در مناطق مختلف متفاوت بود. T. trifolii maculat...
Natural resources are depleted in fragmented landscapes that have their vegetation also altered. As a result, the microhabitat diversity and composition distribution of local species affected. In this study, we evaluated small mammals' community diversity, selection two Atlantic Forest fragments, an ecotone area with Pampa biome, southern Brazil. We recorded five rodents (Akodon montensis, Olig...
Host recognition and use in female parasitoids strongly relies on host fidelity, a plastic behavior which can significantly restrict the host preferences of parasitoids, thus reducing the gene flow between parasitoid populations attacking different insect hosts. However, the effect of migrant males on the genetic differentiation of populations has been frequently ignored in parasitoids, despite...
Many fungal root symbionts of the genus Trichoderma are well-known for their beneficial effects on agronomic performance and protection against plant pathogens; moreover, they may enhance protection from insect pests, by triggering plant resistance mechanisms. Defense barriers against insects are induced by the activation of metabolic pathways involved in the production of defense-related plant...
Updated diagnostic generic characters for the neotropical anthidiine genera Anthidulum and Ctenanthidium are presented. Ctenanthidium versicolor sp. nov. from Argentina and Anthidulum rozeni sp. nov. from Peru are described, illustrated and distinguished from their congeners. A key to the species of Ctenanthidium is provided. The male of Ctenanthidium nigripes Urban, 1993 is described for the f...
Here we present additional data on the Aphidiinae fauna of Kyrgyzstan. We identified 18 species. One species new to science ( Trioxys depressus sp. nov. ) is described, while 11 are reported for first time: Aphidius avenae Haliday, A. ervi matricariae salicis urticae Ephedrus cerasicola Starý, E. niger Gautier, Bonnamour & Gaumont, Lysiphlebus cardui (Marshall), L. confusus Tremblay Ead...
