In the present work, the species Arge quidia Smith, 1989 (Hymenoptera: Symphyta: Argidae) associated with Coccoloba caracasana Meisn, 1856 (Plantae: Polygonaceae) is recorded in the RAMSAR Wildlife Refuge Protected Area, Bahía de Panamá Wetland. Biological and ecological data of A. quidia are provided.

Se Presentan 12 casos clínica y tomográficamente compatibles con tuberculoma cerebral, estudiados Prospectivamente en el Servicio de Neurología del Hospital Nacional Guillermo Almenara Irigoyen entre Setiembre de 1989 y Setiembre de 1992; Todos los Pacientes recibieron quimioterapia antituberculosa, observándose remisión completa de la sintomatología, así como del patrón tomográfico inicial. El tuberculoma cerebral debe ser considerado en el diagnóstico diferencial de los Procesos expansivos intracraneales y en ausencia de otra evidencia, se justifica la Prueba terapéutica con medicamentos antituberculosos.

As far as we can increase the knowledge about parasitoids or any natural enemy of plagues, contributions are relevant. These groups of insects have an important value, since the help to maintain insect population equilibrium and specially insects that are also plagues in different terrestrial ecosystems. The aim of this work is to report for the first time the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae) in pupae of the butterfly Quadrus cerialis (Lepidoptera: Hesperiidae) over seedlings of Piper tuberculatum. These biological observations were made in the Biological Reserve Dr. Rodrigo Tarté, City of Knowledge, Panama province. Six seedlings of Piper reticulatum (Piperaceae); with a mean height of 0.5-1.0 meters, it was located in an open area on the sides of the path, asphalt road inside the Reserve (City of Knowledge). The material was collected and placed in insect hat...

Anastrepha obliqua (Macquart, 1835) (Diptera: Tephritidae), known as the West Indian fruit fly, is a widely distributed species in America. Due to its polyphagous capacity, this insect is of great economic importance, which is studied based on its distribution, forms of management and control. Doryctobracon areolatus (Szépligeti, 1911) (Hymenoptera: Braconidae), a native species, solitary endoparasitoid, koinobiont, has a wide distribution in the Neotropics and subtropics, and due to its capacity as a parasitoid of the genus Anastrepha is a potential candidate for the natural control of this pest. The species Psidium guajava L., native to Mexico, is a fruit with high nutritional value and has great relevance from the commercial perspective. In Panama, the information related to the Parasitoid-Anastrepha-Fruit relationship in this species is limited, so it is of high value to establish r...

Evaluación de la toxicidad aguda y la acción hipolipemiante del aceite de Plukenetia volúbilis, SACHA INCHI EVALUATION OF ACUTE TOXICITY AND HYPOLIPEMIC ACTION OF PLUKENETIA VOLUBILIS, SACHA INCHI

El complejo del género Anastrepha spp. está formado por especies de importancia económica que infestan una amplia variedad de frutas en la región tropical y subtropical. El objetivo del presente estudio fue describir el comportamiento y ciclo biológico asociado al ataque de Anastrepha obliqua (Macquart, 1835) sobre la especie Spondias purpurea L. Se realizaron observaciones biológicas en Alto de la Arena, corregimiento de Veladero, distrito de Tolé, provincia de Chiriquí, Panamá, donde se recolectaron un total de 12 frutos de Spondias purpurea L., se llevaron al laboratorio y se anotaron los datos del ciclo biológico y de comportamiento diariamente. Se determinó que el ciclo biológico de Anastrepha obliqua (Macquart, 1835) tiene duración aproximada de 30 a 32 días en el laboratorio; el estado inmaduro de pupa es el estadio que presentó mayor mortalidad, posiblemente debido...
