13. LABORATORY AND FIELD EVALUATION OF A CYPERMETHRIN-BASED INSECTICIDE FOR THE CONTROL OF ALPHITOBIUS DIAPERINUS PANZER (COLEOPTERA: TENEBRIONIDAE) AND ITS IN-VITRO EFFECTS ON BEAUVERIA BASSIANA BALS. VUILL. (HYPOCREALES: CORDYCIPITACEAE)
ABSTRACT The control of Alphitobius diaperinus is based mainly on chemical insecticides, and the indiscriminate and incorrect use of these products has led to failures in insect control. Thus, it is important to monitor the efficiency of the products available on the market and to develop alternative insect control strategies. The present study evaluated the

14. Biological characteristics of black armyworm Spodoptera cosmioides on genetically modified soybean and corn crops that express insecticide Cry proteins
ABSTRACT This study aimed to evaluate the development and reproduction of the black armyworm, Spodoptera cosmioides when larvae fed on leaves of Bt-corn hybrids, expressing a single Cry1F and also Cry1F, Cry1A.105 and Cry2Ab2 in pyramided corn and their non-Bt-isoline (hybrid 2B688), as well as on leaves of two soybean isolines expressing the Cry1Ac protein

15. CLINICAL ASPECTS OF THE POISONING BY THE PESTICIDE ENDOSULFAN
Endosulfan is an organochlorine insecticide, widely used in insect control. Unfortunately, it is also an acute neurotoxic compound to both insects and mammals, including humans, and has been responsible for many severe poisonings and several fatal cases. Endosulfan also imitates or enhances the effect of the female hormone estrogen, having the capability of

16. Citotoxicity of Fipronil on Hepatocytes Isolated from Rat and Effects of Its Biotransformation
ABSTRACT The aim of this study was to characterize the mechanism of toxicity of fipronil on hepatocytes isolated from the rat and the effect of its biotransformation on the toxicological potential. The toxicity of fipronil was assessed by monitoring the oxygen consumption and mitochondrial membrane potential, intracellular ATP concentration, Ca2+ homeostasis

17. Effects of piperonyl butoxide on the toxicity of the organophosphate temephos and the role of esterases in the insecticide resistance of Aedes aegypti
IntroductionThe effects of piperonyl butoxide (PBO) on the toxicity of the organophosphate temephos (TE) and the role of esterases in the resistance of Aedes aegypti to this insecticide were evaluated.MethodsA. aegypti L4 larvae susceptible and resistant to TE were pre-treated with PBO solutions in acetone at concentrations of 0.125, 0.25, 0.5, 1, and 2% for

18. Impact of insecticide resistance on the field control of Aedes aegypti in the State of São Paulo
IntroductionThe need to control dengue transmission by means of insecticides has led to the development of resistance to most of the products used worldwide against mosquitoes. In the State of São Paulo, the Superintendência de Controle de Endemias(SUCEN) has annually monitored the susceptibility of Aedes aegypti to insecticides since 1996; since 1999, sur

19. Effect of the insecticide Lambda-cyhalothrin on rice spider populations in southern Brazil
The adverse effect that insecticides have on spider populations is of major concern since these predators are a component in the biological control of rice insect pest populations. This study was designed to determine the effect of the pyrethroid insecticide, Lambda-cyhalothrin, on spider populations in rice fields. Treatments consisted of plots treated once

20. Efeito da resistência de Spodoptera frugiperda (J.E.Smith, 1797) (Lepidoptera: Noctuidae) a lambda-cyhalothrin na interação com o milho geneticamente modificado (MON810) e na resposta imunológica ao parasitismo por Campoletis af / Effect of resistance of Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) to lambda-cyhalothrin on the interaction with genetically modified maize (MON810) and the immune response to parasitization by Campoletis aff. flavicincta (Hymenoptera: Ichneumonidae)
Fitness costs of insect resistance to insecticides can be exploited by integrating other pest control strategies in Integrated Pest Management (IPM) programs. The objective of this research was to evaluate the existence of fitness costs associated with the resistance of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) to the pyrethroid insecticid

21. Efeitos do inseticida endossulfam sobre a morfologia e a morfometria testicular em morcegos frugívoros Artibeus lituratus (OLFERS, 1818) / Effects of the endosulfan on the testicular morphology and morphometry in fruit bats Artibeus lituratus (OLFERS, 1818)
Large amounts of agricultural chemicals are discharged into the environment in Brazil. These pesticides are often used to destroy or impair the activity of organisms that attack crops. There are some reports in the literature concerning the decline of many wildlife populations as a result of contamination of their habitats by pesticides. One of the putative

22. The effect of Ageratum fastigiatum extract on Rhodnius nasutus, vector of Chagas disease
Control of Chagas disease is based on insecticide spraying in domiciles in order to exterminate triatomine populations. However, since the vectors differ in susceptibility to currently used insecticides, the screening of the toxic potential of Brazilian flora may identify new molecules lethal to triatomines. This study evaluated the toxicity of ethanolic ext

23. The residual efficacy of a cypermethrin pour-on formulation applied on goats on the mortality and blood intake of Triatoma infestans
Triatoma infestans is the main vector of Trypanosoma cruzi, the aetiological agent of Chagas disease in the Gran Chaco region of South America. As a frequent blood meal source for triatomine bugs, domestic goats play a key role in the eco-epidemiology of Chagas disease. The aim of this study was to evaluate the mortality and blood intake of T. infestans fed

24. Dinâmica do Fomesafen no solo e impacto de Tiametoxam e Fomesafen sobre três espécies de macrófitas aquáticas / Dynamics of fomesafen in soil and impact of thiamethoxam and fomesafen on three freshwater macrophytes
Pesticides are very important to the modern agriculture. However, nowadays, with their increasing use, sometimes indiscriminately, there is also an increasing concern about their soil and water contamination. Fomesafen (herbicide) and thiamethoxam (insecticide) are organic compounds with very different physicochemical properties, but both are used in crops o
