| O controle biológico é uma importante ferramenta para ser utilizada no manejo integrado de insetos-praga. A formulação granulada de fungo Metarhizium anisopliae ainda é uma das mais utilizadas em canaviais do Brasil, porém existe uma dúvida sobre quantos esporos do fungo chegam na base da planta de cana quando aplicados de avião. O objetivo deste estudo foi desenvolver metodologia para avaliar a deposição de micoinseticida granulado, aplicado via aérea, para controle de cigarrinhas-da-raiz da cana. Aplicou-se o fungo M. anisopliae na dose de 1,4 x 1013 conídios/ha, na forma granulada, por meio de avião agrícola com aplicador Swathmaster, na quantidade de 8 kg/ha, e dose de 1,8 x 1013 para 10 kg/ha. Cada parcela teve 48 placas de Petri para coleta dos... |

| The diamondback moth, Plutella xylostella (Lepidoptera: Yponomeutidae), is a serious threat to Brassica vegetables in Iran, including Tehran province. The ovicidal effects of different classes of insecticides on P. xylostella were investigated, using three fixed doses (based on commercial formulations). At the lowest concentration (500 mg L-1), the mortality effect of hexaflumuron and pyridalyl was higher than the other insecticides examined. Fipronil, hexaflumuron and spinosad and pyridalyl, however, showed high toxic effects at the median dose (1000 mg L-1). On the other hand, at high concentration (2000 mg L-1), all insecticides except lufenuron and indoxacarb (EC formulation) caused more than 85% mortality. Overall, these findings indicate that... |

| ABSTRACT The aim of this study was to analyze the effectiveness of different control agents of Aedes aegypti and Aedes albopictus associated with ovitraps under laboratory and field conditions. Five treatments were used: grass infusion + Bacillus thuringiensis israelensis (gI + Bti), grass infusion + Saccharopolyspora spinosa (gI + Ss), grass infusion + Pyriproxyfen (gI + P), distilled water + Toxorhynchites haemorrhoidalis (dW + Th), and grass infusion (gI) (control). The highest mean number of eggs of both species were obtained with grass infusion in the laboratory. Among control agents, the lowest mean of A. aegypti eggs occurred with gI + Ss and the lowest mean of A. albopictus eggs occurred with dW + Th. There was no difference between treatments in... |

| Este trabalho tem como objetivo fornecer informações sobre as pragas do arroz na região e os métodos de controle. Através de levantamentos, coletas e observações efetuadas nos municípios mais produtores, constatou-se a presença da broca-do-colo (Elasmopalpus lignosellus), cupim (Sintermes molestus, Procornitermes spp., Comitermes spp.), pulgão (Rhopolosiphun rufiabdominale Geoica lucifuga), percevejo-castanho (Scaptocoris castanea) percevejo-marrom (Tibraca limbativentris), brocado-colmo (Diatraca saccharalis), percevejo-sugador (Qebalus poecilus), gorgulho (Sitophilus oryzae S. zeamais ), traça (Sitotroga cerealella) e ratos. Ocorrência, identificação das pragas, danos característicos e controle estão sendo enfocados no trabalho, enfatizando-se as pragas... |

| Temperate fruit crops are an important economic activity for growers in southern Brazil. However, several pest species are associated to apple (Malus domestica Borkh.) crops in Brazil. Pesticides are largely used to control them and one way to change this is to combine selective pesticides and predator insects. The goal of this research was to evaluate the effects of the abamectin, carbaryl, fenitrothion, methidathion, sulfur, and trichlorfon pesticides on the survival and stage length of larvae and pupae, adult oviposition from treated larvae, and hatched eggs of two Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) populations. The compounds were sprayed on glass plates in accordance with the International Organization for Biological Control... |

| ABSTRACT The aim of this study was to evaluate the residual effect of pesticides sprayed on peach orchards on S. zeamais. The study consisted of two experiments, according to the method of pesticide application. For Experiment I, pesticides were directly sprayed on peach trees and in Experiment II, the application of pesticides was performed under laboratory conditions. In both Experiments, the effect of pesticides was assessed in laboratory through the release of ten weevils per peach fruit. The effect of treatments was assessed by variable number of surviving insects. The results for pesticides [a.i. (ml or g.100L)] have shown that application of treatments in the field (Experiment I), malathion (200) presented persistence at 1DAT (Days after treatments... |
