Effectiveness of synthetic versus natural human volatiles as attractants for Anopheles gambiae (Diptera: Culicidae) sensu stricto [PDF]

, 2010
Females of the African malaria vector, Anopheles gambiae Giles sensu stricto, use human volatiles to find their blood-host. Previous work has shown that ammonia, lactic acid, and aliphatic carboxylic acids significantly affect host orientation and ...

First detection of the malaria vector Anopheles arabiensis in Côte d’Ivoire: urbanization in question

Malaria Journal, 2022
Background Previous studies have revealed high malaria transmission in Bouaké, Côte d’Ivoire. The sociopolitical crisis in the country and the resulting environmental changes have raised the need to update existing knowledge on mosquito vector species ...

Experimental hut comparisons of nets treated with carbamate or pyrethroid insecticides, washed or unwashed, against pyrethroid-resistant mosquitoes.

, 2004
The efficacy against mosquitoes (Diptera: Culicidae) of a bednet treated with carbamate insecticide [carbosulfan capsule suspension (CS) 200 mg/m(2)] was compared with four types of pyrethroid-treated nets in veranda-trap huts at Yaokoffikro near Bouaké,

Evaluation of the Long-Lasting Insecticidal Net Interceptor LN: Laboratory and Experimental Hut Studies against Anopheline and Culicine Mosquitoes in Northeastern Tanzania [PDF]

, 2013
Long lasting insecticidal nets (LN) are a primary method of malaria prevention. Before new types of LN are approved they need to meet quality and efficacy standards set by the WHO Pesticide Evaluation Scheme.

Effect of blood meals and mating on biodemographic characteristics of Aedes albopictus

Physiological Entomology, EarlyView.
Lifespan did not differ between virgin and mated males and females. The number of blood meals (one and two) significantly reduced adult lifespan compared with those with no blood meal. The effect of the second blood meal doubled females' egg production and their reproductive output.

High vector diversity and malaria transmission dynamics in five sentinel sites in Cameroon

Malaria Journal, 2023
Background Malaria remains one of the main causes of morbidity and mortality in Cameroon. To inform vector control intervention decision making, malaria vector surveillance was conducted monthly from October 2018 to September 2020 in five selected ...

Chemical Cues for Malaria Vectors Oviposition Site Selection:\ud Challenges and Opportunities [PDF]

, 2013
The attractiveness of oviposition site for malaria vector mosquitoes is dependent upon a number of physical and chemical factors. Many aspects of mosquito behavior, including host location and oviposition, are mediated by volatile semiochemicals.

Molecular bases of insect odorant receptor function: specificity and evolution

Biological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Insect Olfactory Receptor‐Expressing Sensor Cells for Colorectal Cancer Diagnosis Using Urine Samples

Cancer Medicine, Volume 15, Issue 4, April 2026.
We developed a novel, noninvasive diagnostic method for colorectal cancer using sensor cells expressing insect ORs that detect volatile organic compounds in urine samples. By analyzing the luminescence responses of sensor cells and applying machine learning, our model achieved 80% sensitivity and an ROC‐AUC of 0.84 in distinguishing colorectal cancer ...
