Algarrobo trees, Prosopis sp., were assessed at Tongorrape forest (Motupe-Lambayeque) in order to know infestation and damages levels of Heteropsylla texana Crawford, and natural enemies of the pest. Assessments, 10 in total, were carried out each 15 days from march to july, 2014. Algarrobo trees were selected taking on account similarity in height, age and foliage density. Infestation was evaluated with a scale from grade 0 to 5 on five terminal buds per tree. On each tree, by sight, foliage damage intensity was determined under a scale from grade 0 to 5. Terminal buds were conditioned on plastic jars to carry them to an insect recovery laboratory. Insect identification was carried out at La Molina-Lima SENASA entomological museum. Infestation varied from grade 1 to 3, which means that psilid population level was from low to moderate, while damage intensity varied from 2 to 3 grade, whi...

Algunas regiones en Ecuador permanecen poco estudiadas y en donde el conocimiento sobre las especies de primates es limitado. Una de estas zonas es la cuenca del río Morona, en la provincia de Morona Santiago, ubicada en el sureste del país. Para abordar este vacío de conocimiento realizamos un trabajo de campo en la región entre 2019 y 2024, con el objetivo de recopilar datos sobre sus especies de primates y evaluar su estado de conservación. Mediante caminatas de observación y entrevistas con habitantes locales, registramos 10 especies de primates (Leontocebus lagonotus, Cebus yuracus, Sapajus apella, Saimiri macrodon, Aotus vociferans, Plecturocebus discolor, Pithecia cf. aequatorialis, Alouatta seniculus, Ateles belzebuth y Lagothrix lagothricha); entre ellas, por la frecuencia de avistamientos destacaron: Saimiri macrodon, Leontocebus lagonotus y Plecturocebus discolor.
