Insecticide treated curtains and residual insecticide treatment to control Aedes aegypti: an acceptability study in Santiago de Cuba Institute of Tropical Medicine Ghent University

Dennis Perez, Patrick van der Stuyft, Maria Eugenia Toledo, Enrique Ceballos, Francisco Fabre, Pierre Lefèvre

Background

Within the context of a field trial conducted by the Cuban vector control program (AaCP), we assessed acceptability of insecticide-treated curtains (ITCs) and residual insecticide treatment (RIT) with deltamethrin by the community. We also assessed the potential influence of interviewees' risk perceptions for getting dengue and disease severity.

Methodology/principal findings

We embedded a qualitative study using ...

Prenatal exposure to pyrethroid and organophosphate insecticides and language development at age 20-36 months among children in the Odense Child Cohort University of Antwerp

Helle Raun Andersen, Louise Dalsager, Inge Kjaer Jensen, Clara Amalie Gade Timmermann, Trine Staak Olesen, Fabio Trecca, Flemming Nielsen, Greta Schoeters, Henriette Boye Kyhl, Philippe Grandjean, et al.
Background: Prenatal exposure to organophosphate and pyrethroid insecticides has been associated with impaired neurodevelopment. Few longitudinal studies have investigated associations with early language development in populations with mainly low dietary exposure. Objective: To investigate associations between biomarkers of maternal gestational exposure to organophosphate and pyrethroid insecticides and the child & rsquo;s language ...

Susceptibility status of the wild-caught Phlebotomus argentipes (Diptera Psychodidae: Phlebotominae), the sand fly vector of visceral leishmaniasis, to different insecticides in Nepal Institute of Tropical Medicine

BACKGROUND: Visceral leishmaniasis (VL) is targeted for elimination as a public health problem in Nepal by 2023. For nearly three decades, the core vector control intervention in Nepal has been indoor residual spraying (IRS) with pyrethroids. Considering the long-term use of pyrethroids and the possible development of resistance in the vector Phlebotomus argentipes sand flies, we monitored the susceptibility status of their field populations ...

This study aimed to describe the residential use of insecticides in a birth cohort in Spain. Study subjects were 2 456 women enrolled into the INMA (Environment and Childhood) birth cohort followed prospectively during pregnancy and in the early postnatal period. The women were recruited at the beginning of their pregnancy between 2003 and 2008 in four regions of Spain. Socio-demographic, environmental and lifestyle information was obtained at ...

Evaluation of the susceptibility of the pea aphid, Acyrthosiphon pisum, to a selection of novel biorational insecticides using an artificial diet Ghent University

Amin Sadeghi, Els Van Damme, Guy Smagghe
An improved technique was developed to assay the toxicity of insecticides against aphids using an artificial diet. The susceptibility of the pea aphid Acyrthosiphon pisum (Harris) (Hemiptera: Aphidoidea) was determined for a selection of novel biorational insecticides, each representing a novel mode of action. Flonicamid, a novel systemic insecticide with selective activity as feeding blocker against sucking insects, showed high toxicity against ...

Are mummies and adults of Eretmocerus mundus (Hymenoptera: Aphelinidae) compatible with modern insecticides? Ghent University

Maria del Mar Fernandez, Pilar Medina, Alberto Fereres, Guy Smagghe, Elisa Vinuela
The parasitic wasp Eretmocerus mundus (Mercet) is an important natural enemy of the widespread key pest Bemisia tabaci (Gennadius). The toxicity of 11 modern insecticides applied at their maximum field recommended rate in Spain was tested in two life stages of E. mundus: adults and mummies. Laboratory and persistence tests were conducted and effects assessed not only in terms of mortality but on reproductive performance as well. Some ...

Novel chlorantraniliprole derivatives as potential insecticides and probe to chlorantraniliprole binding site on ryanodine receptor KU Leuven

Min Luo
The lepidopteran pests such as diamondback moth are the regularly harmful pests of crops in the world, which brings enormous losses in crop production. Chlorantraniliprole is an anthranilic diamide insecticide registered for the control of lepidopteran pests with high insecticidal activity, however with uncertain binding site action target of chlorantraniliprole on ryanodine receptor, a series of new chlorantraniliprole derivatives were ...
