Insecticide control in a Dengue epidemics model [PDF]

open access: yesAIP Conf. Proc. 1281 (2010), no. 1, 979--982, 2010
A model for the transmission of dengue disease is presented. It consists of eight mutually-exclusive compartments representing the human and vector dynamics. It also includes a control parameter (insecticide) in order to fight the mosquitoes. The main goal of this work is to investigate the best way to apply the control in order to effectively reduce ...

An optimal control approach to malaria prevention via insecticide-treated nets [PDF]

open access: yesConference Papers in Mathematics, vol. 2013, Article ID 658468, 8 pages, 2013, 2013
Malaria is a life threatening disease, entirely preventable and treatable, provided the currently recommended interventions are properly implemented. These interventions include vector control through the use of insecticide-treated nets (ITNs). However, ITN possession does not necessarily translate into use.

Advances in electrochemical detection methods for measuring contaminants of emerging concerns

open access: yesElectrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract The presence of contaminants of emerging concerns (CECs) such as pharmaceuticals and personal care products, endocrine disrupting compounds (EDCs), per/poly‐fluorinated substances (PFAS), pesticides, and nanomaterials poses significant challenges to the environment and human health.

Aquatic‐Terrestrial Insecticide Fluxes: Midges as Neonicotinoid Vectors

open access: yesEnvironmental Toxicology and Chemistry, Volume 42, Issue 1, Page 60-70, January 2023., 2023
Abstract Exposure of freshwater ecosystems to insecticides can negatively impact the development of emerging aquatic insects. These insects serve as an important nutritional subsidy for terrestrial insectivores. Changes in insect emergence phenology (i.e., emergence success and temporal pattern) or fluxes of insecticides retained by the emerging adults

Cocktail effect of Profenophos and Abamectin on tadpoles of Asian Common Toad (Duttaphrynus melanostictus)

open access: yesCeylon Journal of Science, 2018
Farmers mix two or more pesticides as mixing saves the spraying time and the labour cost and also with the idea that it increases the efficiency. The cocktail effect of two agrochemicals, profenophos and abamectin, was tested on the tadpoles of the Asian

Effects of insecticides intended for Ceutorhynchus napi Gyll. control in oilseed rape on ground beetles [PDF]

open access: yesPesticidi i Fitomedicina, 2017
The effects of insecticides that are commonly used for conventional and integrated oilseed rape (OSR) management on ground beetles were studied. Monitoring of harmful species showed that only insecticides intended against Ceutorhynchus napi should be ...

Using the Honey Bee (Apis mellifera L.) Cell Line AmE‐711 to Evaluate Insecticide Toxicity

open access: yesEnvironmental Toxicology and Chemistry, Volume 42, Issue 1, Page 88-99, January 2023., 2023
Abstract One of the main contributors to poor productivity and elevated mortality of honey bee colonies globally is insecticide exposure. Whole‐organism and colony‐level studies have demonstrated the effects of insecticides on many aspects of honey bee biology and have also shown their interactions with pathogens.

Defining the Biologically Plausible Taxonomic Domain of Applicability of an Adverse Outcome Pathway: A Case Study Linking Nicotinic Acetylcholine Receptor Activation to Colony Death

open access: yesEnvironmental Toxicology and Chemistry, Volume 42, Issue 1, Page 71-87, January 2023., 2023
Abstract For the majority of developed adverse outcome pathways (AOPs), the taxonomic domain of applicability (tDOA) is typically narrowly defined with a single or a handful of species. Defining the tDOA of an AOP is critical for use in regulatory decision‐making, particularly when considering protection of untested species.
