1. Interações do algodão Bt, do inseticida imidacloprid e do predador Podisus nigrispinus Dallas (Hemiptera: Pentatomidae) no manejo da resistência de Spodoptera frugiperda (J.E.Smith) (Lepidoptera: Noctuidade) a lambda-cyhalot / Interactions of Bt cotton, of insecticide imidacloprid, and the predator Podisus nigrispinus Dallas (Hemiptera: Pentatomidae) on the resistance management of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) to lambda-cyhalothrin
O presente estudo objetivou identificar as interações do Algodão Bt que expressa Cry1Ac (Bollgard®), com o predador Podisus nigrispinus Dallas (Hemiptera: Pentatomidae), no manejo da resistência de Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) a lambda-cyhalothrin em duas condições: ausência e presença do inseticida imidacloprid. Foram

2. Estudo do mecanismo de ação da atividade acaricida de Calea serrata (Asteraceae) em Rhipicephalus (Boophilus) microplus e da sua toxicidade em roedores
It has been demonstrated that the n-hexane extract of Calea serrata had acaricidal activity against larvae of R. microplus and R. sanguineus. Acetylcholinesterase (AChE), an enzyme that hydrolyses acetylcholine at cholinergic synapses, is a target for pesticides and its inhibition by organophosphates leads to paralysis and death of arthropods. Extensive uses

4. Carunchos VS inseticidas: individualidade importa? / Maize weevils VS inseticides: does individuality matters?
Behavior is the expression of an organism s interactions with the environmental stimulus. Even though behavioral studies are done in an individual level, the conclusions are drawn for populations. The importance of an individual s behavior have been studied on several animal groups, a few examples are: primates, mammals and insects. From these results, the c

6. BIOATIVIDADE DE EXTRATOS VEGETAIS NO CONTROLE DE Sitophilus oryzae (LINNÉ, 1763) EM ARROZ / BIOACTIVITY OF VEGETABLE EXTRACTS ON THE CONTROL OF Sitophilus oryzae (LINNÉ, 1763) IN RICE
The continuous growth of the world population, intensive competition among humans and plant pests for the same food sources, the resistence to existing inseticides by some insects and the persistence of residues in the environment and food created the necessity for new insecticides. In this research field, vegetable species appear as a promising source of ne

7. Control of the german cockroach Blattella germanica with Metarhizium anisopliae and insect growth regulators. / Controle de Blattella germanica (L.) com Metarhizium anisopliae e inseticidas reguladores de crescimento.
It was evaluated the effect of Metarhizium anisopliae and the insect growth regulators triflumuron and pyriproxifen for adults and nymphs of the German cockroach Blattella germanica, and the efficacy of its association in the control of this urban pest. High doses of the pathogen caused high mortality of adults and nymphs. There was no mortality of B. german
