Native hosts and parasitoids associated with anastrepha fractura and other anas...

A new natural host for Anastrepha fractura Stone, Salacia sp., is reported for the first time in Brazil. Parasitoids attacking A. fractura are also reported. We also report Anastrepha distincta Greene infesting Inga cinnamomea in Brazil for the first time. New associations between Anastrepha species and parasitoids are also reported.

Ocorrência e danos de Hybolabus amazonicus Voss e Hybolabus columbinus (Erichso...

The occurrence of Hybolabus amazonicus Voss and Hybolabus columbinus (Erickson) damaging leaves of the Brazil nut (Bertholietia excelsa, Lecythidaceae) is reported. Adults fed on the surface of the leaves causing damage, and females cut and rolled the young leaves for nest construction. Injuries were more visible in young plants than in old ones.

A utilização de extratos de plantas pode ser uma alternativa para o controle de pragas. Dentre as plantas com atividade inseticida, destacam-se a erva-de-rato (Palicourea marcgravii) e o subproduto (manipueira) da produção de farinha de mandioca (Manihot esculenta), plantas comuns na região Amazônica. Esse trabalho teve, como principal objetivo, investigar o potencial inseticida da manipueira e do extrato de er...

State of the science and the way forward for the ecotoxicological assessment of...

Over the past two decades, soil ecotoxicologists have made strides in utilizing the basic concepts and advancements in soil zoology and ecology. They have applied the existing tools, and developed new ones to investigate how chemical contamination can affect soil ecosystems, including the degradation or destruction of soil quality and habitats or the diminishment of belowground biodiversity. Soil ecotoxicologis...
