1. Monitoring and risk assessment due to presence of metals and pesticides residues in honey samples from the major honey producing forest belts and different brands
Abstract Honey is consumed worldwide because of its nutritional, therapeutic and medicinal purposes. Generally it is perceived that honey reaches its consumer in pure form however this is not always true as contaminants can end up in honey. Thus this study was designed to check the presence of contaminants in honey samples. For this purpose 52 samples were c

3. Susceptibility of boll weevil to ready-to-use insecticide mixtures
RESUMO: Bicudo-do-algodoeiro é a principal praga do algodoeiro no Brasil, sendo o uso de inseticidas amplamente recomendado para o seu controle. A suscetibilidade do bicudo-do-algodoeiro foi determinada a inseticidas em formulação simples ou em misturas prontas para uso, as quais têm sido recomendadas para pulverizar campos de algodão sob a hipótese de

4. STUDY OF THE EFFECTS OF ADJUVANTS ASSOCIATED WITH INSECTICIDES ON THE PHYSICOCHEMICAL PROPERTIES OF THE SPRAY SOLUTION AND CHARACTERIZATION OF DEPOSITS ON WHEAT AND MAIZE LEAVES UNDER SIMULATED RAIN
ABSTRACT The association of adjuvants with phytosanitary products has been tested for several years but is commonly recommended without considering technical and scientific criteria. This study aimed to evaluate the influence of the association of insecticides with different adjuvants on surface tension, contact angle, coverage, hydrogen ionic potential (pH)

5. Effects of insecticide and acaricide mixtures on Diaphorina citri control
Resumo Misturas de agrotóxicos são comumente utilizadas para reduzir os custos de produção na agricultura. No entanto, as consequências de tal prática para organismos-alvo ainda são desconhecidas na maioria dos casos. Portanto, este trabalho teve como objetivo avaliar os efeitos de combinações de inseticidas e um acaricida utilizado mundialmente no

6. Experimental hut to study the indoor behaviour and effects of insecticide-treated bednets on phlebotomine sand flies (Diptera: Psychodidae)
BACKGROUND Behavioural effects of insecticides on endophagic phlebotomine sand fly vectors of Leishmania are poorly understood mainly because of the lack of an experimental hut (EH) in which to study them. OBJECTIVE To build an EH to evaluate the effects of long-lasting insecticide-treated nets (LLINs) on Lutzomyia longiflocosa. METHODS The study had two

7. SPRAY DRIFT AND CATERPILLAR AND STINK BUG CONTROL FROM AERIAL APPLICATIONS WITH ELECTROSTATIC CHARGE AND ATOMIZER ON SOYBEAN CROP
ABSTRACT: The use of aerial application with electrostatic charge is an alternative to improve the quality of insecticide applications in soybean crop. The objective of this study was to evaluate the drift and chemical control of the caterpillar and stink bug complex promoted by aerial applications of insecticide in the soybean crop, using electrostatic spra

8. SPRAY DRIFT AND PEST CONTROL FROM AERIAL APPLICATIONS ON SOYBEANS
ABSTRACT Pesticide drift is an issue in modern farming, mainly for crops under constant spraying as soybeans. This study aimed at assessing drift and pest control for aerial applications in soybean crops. Hydraulic nozzles and rotary atomizers, regulated to a wide spectrum of droplet sizes, sprayed thiamethoxam plus lambda-cyhalothrin using an agricultural a

9. 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

12. 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
