1. Combined application of Isaria fumosorosea and beta-cyfluthrin in the control of coffee leaf miner
ABSTRACT The coffee leaf miner is responsible for significant decreases in coffee production. To mitigate the problems caused by this pest control strategies need to be applied. The combined application of chemical and biological insecticides is an alternative that can reduce the population of leaf miner in areas with high infestation and occurrence of resis

3. Richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides in rice paddy fields
ABSTRACT The objective of this study was to verify the richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides of the rice paddy fields. In the crop seasons of 2012/13 and 2013/14, field experiments were performed, which consisted of single-dose applications of the fungicides trifloxystrobin + tebuconazole and

5. Silicon influence on resistance induction against Bemisia tabaci biotype B (Genn.) (Hemiptera: Aleyrodidae) and on vegetative development in two soybean cultivars
The potential of populations of Bemisia tabaci (Genn.) to become resistant to insecticides has stimulated research into alternative tactics of integrated pest management such as the induction of host-plant resistance. Recent data have shown that silicon can increase the degree of resistance of host plants to insect pests. Therefore the aim of our work was to

6. Spread of phosphine resistance among brazilian populations of three species of stored product insects
The resistance to fumigant insecticides in stored-products insects is often recorded. Several factors influence the evolution of insecticide resistance. Among these, the frequency of applications and the migration of resistant populations are of primary importance for the stored-product insects. The aim of this study was to characterize the spectrum and inve

7. Resistance of Diamonback moth, Plutella xylostella (L.,1758) (Lepidoptera : Plutellidae) populations from Pernambuco state to insecticides / Resistência de populações pernambucanas de traças-das-crucíferas, Plutella xylostella (L.,1758) (Lepidoptera : Plutellidae) a inseticidas
Plutella xylostella (L.) (Lepidoptera: Plutellidae), popularly known as diamondback moth, is a major pest of brassicaceae crops (e.g., kale, cauliflower, broccoli, and cabbage) throughout the world. Several insecticides have been intensively used during several cultivation cycles and, even in some areas, up to 15 to 20 applications per season have been obser

9. Inseticidas alternativos no controle de moscas sinantrópicas. / Alternative insecticides in the control of sinantropic flies.
The flies Lucilia cuprina, Chrysomya megacephala, Cochliomyia hominivorax e Musca domestica, which produce myiasis and carry pathogenic microorganisms, cause large damage to the cattle-breeding. With the aim to enlarge the options about insecticides less aggressive for the environment was investigated, under laboratory and in field conditions, several concen

10. Efeito de alguns inseticidas sobre a mariposa Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae) por meio de iscas esterilizantes. / Inseticide effects on the diamondback moth Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae) by using sterilizing baits.
Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae), commonly known as diamondback moth, is an important pest of Brassicaceae in Brazil and several other countries. Its control is usually done with frequent applications of conventional insecticides. However, this approach is sometimes ineffective, besides some drawbacks such as environmental contaminat

11. Suscetibilidade de Spodoptera frugiperda (Lepidoptera: Noctuidae) a metaflumizone na cultura do milho: bases para o manejo da resistência / Susceptibility of Spodoptera frugiperda (Lepidoptera: Noctuidae) to metaflumizone in maize: basis for resistance management
Metaflumizone is a new insecticide, belonging to the new chemical group semicarbazone, with excellent activity against many species of Lepidoptera Order. The product acts in the nervous system of insects blocking the sodium channels without metabolic activation, in other words, the molecule is toxic on its original form. The mechanism of action of metaflumiz

12. Histophysiology of the food channel and hemocytes of Spodoptera frugiperda (J.E. Smith) (Lepidoptera : Noctuidae) treated with neem (Azadirachta indica A.Juss) / Histofisiologia do canal alimentar e hemócitos de Spodoptera frugiperda (J.E. Smith) (Lepidoptera : Noctuidae) tratadas com Nim (Azadirachta indica A.Juss)
Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is the main pest of corn crops. The control of S. frugiperda requires various insecticide applications that might result on selection of resistant populations and environmental contamination. A promising alternative toward the control of this pest is the use of vegetal insecticides such as neem, Aza
