Malaria vector density entomological surveillance system evaluation, Zambezia, Mozambique, 2017-2019

open access: yesJournal of Interventional Epidemiology and Public Health
Introduction: Vector density is the degree of domiciliation of malaria vectors that influence the vectorial capacity of mosquito populations in different regions and at different times.

An experimental hut evaluation of PermaNet(®) 3.0, a deltamethrin-piperonyl butoxide combination net, against pyrethroid-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes in southern Benin.

open access: yes, 2010
PermaNet 3.0 is a long-lasting combination net with deltamethrin present on the sides and a mixture of deltamethrin and piperonyl butoxide (PBO), an oxidase synergist, on the top panel.

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

open access: yesInsect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

Carbon dioxide baited trap catches do not correlate with human landing collections of Anopheles aquasalis in Suriname [PDF]

open access: yes, 2011
Three types of carbon dioxide-baited traps, i.e., the Centers for Disease Control Miniature Light Trap without light, the BioGents (BG) Sentinel Mosquito Trap (BG-Sentinel) and the Mosquito Magnet® Liberty Plus were compared with human landing ...

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

open access: yesInsect Science, EarlyView.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...

Morphological and molecular identification of Anopheles (Diptera: Culicidae) mosquitoes in Surkhandarya region, Uzbekistan

open access: yesActa Biologica Sibirica, 2023
Mosquitoes of the genus Anopheles Meigen, 1818 are representatives of blood-sucking insects from the family Culicidae. Some representatives of this genus carry malaria and distribute through humans.

A CRISPR-Cas9 sex-ratio distortion system for genetic control. [PDF]

open access: yes, 2016
Genetic control aims to reduce the ability of insect pest populations to cause harm via the release of modified insects. One strategy is to bias the reproductive sex ratio towards males so that a population decreases in size or is eliminated altogether ...

Neoclassical development of genetic sexing strains for insect pest and disease vector control

open access: yesInsect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Impact of full coverage of population with Long-Lasting Insecticidal Nets (LLINs) on malaria vector density in Gadchiroli district of Maharashtra, India

open access: yesJournal of Vector Borne Diseases
Background & objectives: Long-lasting insecticidal nets (LLINs) are a major weapon in the fight against malaria. But protection of each family member is not possible with current distribution system with 80% coverage.

Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

open access: yesIntegrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...
