The selectivity of different insecticides, fungicides and fertilizers used in organic soybean cropping was evaluated according to the protocols proposed by the Pesticides and Beneficial Organisms Working Group of the International Organization for Biological Control (IOBC) concerning adults and pupae of ...
A traça Tuta absoluta (Meyrick) é o inseto-praga que mais compromete a produção do tomateiro. Basear o seu controle no uso de inseticidas sintéticos pode comprometer a cultura em termos econômicos e ambientais. Como alternativa de controle, o óleo de nim foi aplicado em folhas de tomateiro, avalia...
Background Mosquitoes are important vectors of several diseases, including malaria and dengue, and control measures are mostly performed using chemical insecticides. Unfortunately, mosquito resistance to commonly applied insecticides is widespread. Therefore, a prospection for new molecules with insectic...
BACKGROUND: Essential oils extracted from aromatic and medicinal plants have many biological properties and are therefore an alternative to the use of synthetic products. The chemical composition of essential oils from two medicinal plants (Eucalyptus globulus and E. lehmannii) was determined and, their ...

A substituição periódica de cultivares pelos produtores pode alterar os níveis de danos econômicos e de controle de pragas, e desta forma comprometer o sucesso no manejo do curuquerê-do-algodoeiro. O objetivo deste trabalho foi avaliar os efeitos dos desfolhamentos simulados em cultivares atualment...
A Bemisia tuberculata (Bondar, 1923) é atualmente a principal praga da cultura da mandioca. Este trabalho descreve o efeito de diferentes concentrações do extrato CHCl3 das folhas de Anacardium humile, em relação à Bemisia tuberculata, em condições de laboratório, em plantas de mandioca, além d...
Phytovirus vectors Frankliniella schultzei (Trybom, 1920) (Thysanoptera: Thripidae) and Myzus
persicae (Sulzer, 1776) (Hemiptera: Aphididae) feed on crops of great economic importance brings large economic losses
worldwide to cultivated species such as tomato and cotton. F. schultzei transmits Tospovirus...
Background: The horn fly, Haematobia irritans, is an obligate bloodsucking ectoparasite of pastured cattle and is a major pest of livestock production in North and South America and Europe. In this study, we investigated the potential to use cattle pastures, infected with non-toxic, "friendly" fungal-end...
Natural insecticides from plant extracts represent an alternative to the highly toxic synthetic products in order to reduce environmental contamination; however some might also be toxic for non-target organisms. The present study determined the 50% lethal concentration (48h; LC50) for adults Nile tilapia...
Objective: To describe the use of chemical insecticides throughout history as the main tool to fight against Aedes aegypti, a vector of dengue virus. Methods: A text mining approach was conducted on databases, such as PUBMED and SCIENCE DIRECT, using the keywords “Aedes aegypti”, combined wit...
