Insecticidal and repellent effect of cinnamon oil on flies associated with livestock

Rev. MVZ Córdoba; 23 (2), 2018
Abstract Objective. Due to the increased parasitic resistance, there is a need to explore alternative insecticides, including natural products, such essential oils. In this sense, the aim of this study was to evaluate, for the first time, the insecticidal and repellent effect of Cinnamomun zeylanicum (fr...

Ototoxicity of boric acid powder in a rat animal model

Abstract Introduction: Boric acid, which has antiseptic and acidic properties, is used to treat external and middle ear infections. However, we have not found any literature about the effect of boric acid powder on middle ear mucosa and inner ear. Objective: The purpose of this study is to investigate ...

Variation in temephos resistance in field populations of Aedes aegypti (Diptera: Culicidae) in the State of Sergipe, Northeast Brazil

Abstract INTRODUCTION The organophosphate temephos was first used in Brazil in the 1960s for the control of Aedes aegypti. Because of its extensive and longstanding use worldwide, selection for mosquito populations resistant to the chemical has been observed not only in different regions of Brazil but ...

Compatibility of chemical insecticides and entomopathogenic fungi for control of soybean defoliating pest, Rachiplusia nu

Rev. argent. microbiol; 50 (2), 2018
Rachiplusia nu (Guenée) (Lepidoptera: Noctuidae) is one of the major lepidopteran pests defoliating soybeans (Glycine max Merrill) in Argentina. The combined use of chemical insecticides and entomopathogenic fungi is a promising pest-control option to minimize adverse chemical effects. In this work, we ...

Toxicity and motor changes in Africanized honey bees (Apis mellifera L) exposed to fipronil and imidacloprid

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT This study evaluated the in vitro toxicity and motor activity changes in African-derived adult honey bees (Apis mellifera L.) exposed to lethal or sublethal doses of the insecticides fipronil and imidacloprid. Mortality of bees was assessed to determine the ingestion and contact lethal dose for ...

Avaliação da atividade locomotora de Aedes aegypti (Diptera: Culicidae) com diferentes perfis de resistência a inseticidas do Estado de São Paulo

Diversas populações de Aedes (Stegomyia) aegypti (Linnaeus) têm mostrado resistência a muitos inseticidas químicos, empregados no controle desse vetor de arboviroses como dengue, chikungunya, Zika e febre amarela urbana. O presente trabalho teve como objetivo avaliar quantitativamente a atividade lo...

Survival and injuries of Deois flavopicta (Stal, 1854) in pastures under seed treatment with insecticides and dry mass yield

Arq. Inst. Biol; 85 (), 2018
The present study evaluated the survival and injuries of Deois flavopicta (Hemiptera: Cercopidae) in pastures of Urochloa (Syn. Brachiaria) decumbens and U. brizantha, submitted to seed treatment with fipronil (Amulet®) and thiamethoxam (Cruiser 350 FS®), and dry mass yield. The experiment, carried out...

Evaluation of the effectiveness of using deltamethrinimpregnated collars to control visceral leishmaniasis in the municipality of Votuporanga, State of São Paulo, Brazil, 2014 – 2016

O objetivo deste artigo é apresentar os principais resultados do Projeto de Inovação Tecnológica em Saúde realizado entre 2014 e 2015, destacando-se o uso de coleiras impregnadas com deltametrina a 4% em cães em uma região endêmica para leishmaniose visceral (LV), o município de Votuporanga, Sã...

Models of Disease Vector Control: When Can Aggressive Initial Intervention Lower Long-Term Cost?

Bull. math. biol; 80 (), 2018
Insecticide spraying of housing units is an important control measure for vector-borne infections such as Chagas disease. As vectors may invade both from other infested houses and sylvatic areas and as the effectiveness of insecticide wears off over time, the dynamics of (re)infestations can be approxima...

Efectos de diferentes dosis subletales de deltametrina sobre la inestabilidad en el desarrollo de alas y la eficiencia reproductiva en Triatoma infestans (Hemiptera: Reduviidae, Triatominae)
Effects of differents subletal doses of deltametrina about the instability in wing development and reproductive efficency of Triatoma infestans (Hemiptera: Reduviidae, Triatominae)

El control químico del vector representa la herramienta de mayor importancia para el manejo de la enfermedad de Chagas en zonas endémicas. El rociado con deltametrina se viene realizando desde hace 30 años. Aún así, la efectividad de este compuesto ha disminuido en la última década a causa de la r...
