3. Mitigating the impact of organochlorine and pyrethroid residues in fresh and chemically washed spinach
Abstract Spinach is highly contaminated with different pesticide residues. This study was designed to evaluate organochlorine and pyrethroid pesticide residues present in various washing treatments (T0-T13) of fresh and chemically washed spinach with respect to maximum residues limits. Efficiency of washing solutions (citric acid, acetic acid, garlic extract

4. Resistance of the stable fly, Stomoxys calcitrans (Diptera: Muscidae), to cypermethrin in outbreak areas in Midwestern Brazil
Resumo Explosões populacionais da mosca-dos-estábulos (Stomoxys calcitrans) tornaram-se uma séria preocupação para a pecuária próxima a usinas de cana-de-açúcar em algumas regiões do Brasil, devido à massiva reprodução da mosca em resíduos e subprodutos do processamento da cana. Apesar da limitada eficiência dos inseticidas no controle dos sur

5. Insecticide resistance and control failure likelihood among populations of the boll weevil (Anthonomus grandis) from Mato Grosso (Brazil)
ABSTRACT. The cotton producers from southern Mato Grosso are currently experiencing control failure with the use of the use of insecticides against the cotton boll weevil Anthonomus grandis Boheman, the main pest species of this commodity. Therefore, the present study was designed to survey insecticide resistance and the associated likelihood of control fail

6. Strategy for Correction of Matrix Effect on the Determination of Pesticides in Water Bodies Using SPME-GC-FID
This paper investigates a strategy as a quality control parameter, using standard surrogate and determination of a relation factor for determination of parathion-methyl, chlorpyriphos and cypermethrin pesticides in environmental aqueous matrices with distinct characteristics (river water, estuarine, seawater and weir water), using the technique of solid phas

8. 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

9. Anopheles darlingi and Anopheles marajoara (Diptera: Culicidae) susceptibility to pyrethroids in an endemic area of the Brazilian Amazon
Abstract: INTRODUCTION: This study aimed to evaluate the susceptibility of Anopheles darlingi Root (1926) and Anopheles marajoara Galvão & Damasceno (1942) to pyrethroids used by the National Malaria Control Program in Brazil. METHODS: Mosquitoes from Amapá, Brazilian Amazon, were assessed for resistance to cypermethrin, deltamethrin, and alpha-cypermeth

10. Biodegradation of cypermethrin by immobilized cells of
Micrococcus sp. strain CPN 1Pyrethroid pesticide cypermethrin is a environmental pollutant because of its widespread use, toxicity and persistence. Biodegradation of such chemicals by microorganisms may provide an cost-effective method for their detoxification. We have investigated the degradation of cypermethrin by immobilized cells of

11. Susceptibility of Triatoma sordida Stal, 1859 (Hemiptera: Reduviidae) to alpha-cypermethrin under natural climatic conditions
Abstract:INTRODUCTION:Despite the recommendations by interpretation of resistance ratios obtained in laboratory bioassays, little is known about the actual impact of these results in the effectiveness of vector control activities in the field. In this context, our objective was to determine the mean value of different resistance ratios obtained by laboratory

12. CONTAMINAÇÃO DE AMBIENTES AQUÁTICOS POR "AGROTÓXICOS URBANOS”: O CASO DOS RIOS COCÓ E CEARÁ, FORTALEZA – CEARÁ, BRASIL
Pesticides are used mostly in rural areas for agriculture, but urban pest control, public health campaigns, and household and veterinary products can also be important sources of these contaminants. This aim of this study was to estimate household pesticide contamination in sediments of two urban estuaries due to pest control: Cocó and Ceará rivers loca
