Larvivorous potentiality of Puntius tetrazona and Hyphessobrycon rosaceus against Culex vishnui subgroup in laboratory and field based bioassay

open access: yesBMC Research Notes, 2018
Objectives This study assessed the predatory potentiality of two unexplored fishes, Puntius tetrazona and Hyphessobrycon rosaceus on Culex vishnui subgroup larvae in order to utilize natural resources to diminish mosquito population.

Automating the Surveillance of Mosquito Vectors from Trapped Specimens Using Computer Vision Techniques [PDF]

open access: yesarXiv, 2020
Among all animals, mosquitoes are responsible for the most deaths worldwide. Interestingly, not all types of mosquitoes spread diseases, but rather, a select few alone are competent enough to do so. In the case of any disease outbreak, an important first step is surveillance of vectors (i.e., those mosquitoes capable of spreading diseases).

Validation of a multi-residue method to determine deltamethrin and alpha-cypermethrin in mosquito nets by gas chromatography with electron capture detection (GC-µECD) [PDF]

open access: yes, 2013
Background: Nowadays long-lasting insecticidal mosquito nets (LNs) are frequently used around the world to protect people against malaria vectors. As they contain insecticide, laboratory control is needed to check whether the content of the active ...

Live calcium imaging of Aedes aegypti neuronal tissues reveals differential importance of chemosensory systems for life-history-specific foraging strategies. [PDF]

open access: yes, 2019
BackgroundThe mosquito Aedes aegypti has a wide variety of sensory pathways that have supported its success as a species as well as a highly competent vector of numerous debilitating infectious pathogens.

Novel factors of Anopheles gambiae haemocyte immune response to Plasmodium berghei infection [PDF]

open access: yes, 2016
Background Insect haemocytes mediate cellular immune responses (e.g., phagocytosis) and contribute to the synthesis of humoral immune factors. In previous work, a genome-wide molecular characterization of Anopheles gambiae circulating haemocytes was ...

Comparison of immunohistochemistry and polymerase chain reaction for detection of West Nile virus in naturally infected dead birds

open access: yesJournal of Infection in Developing Countries, 2010
Introduction: Credible vector-borne disease surveillance programs, especially in developing countries with limited resources, must include diagnostic tests that are efficient, inexpensive and simple and safe to administer while maintaining high levels ...

A discrete-time dynamical system of wild mosquito population with Allee effects [PDF]

open access: yesarXiv, 2021
We study a discrete-time dynamical system of wild mosquito population with parameters: $\beta$ - the birth rate of adults; $\alpha$ - maximum emergence rate; $\mu>0$ - the death rate of adults; $\gamma$ - Allee effects. We prove that if $\gamma\geq\frac{\alpha(\beta-\mu)}{\mu^2}$ then the mosquito population dies and if $\gamma<\frac{\alpha(\beta-\mu)}{

Sterile insect technology for control of Anopheles mosquito: a mathematical feasibility study [PDF]

open access: yes, 2011
Anopheles mosquito is a vector responsible for the transmission of diseases like Malaria which a_ect many people. Hence its control is a major prevention strategy.

The isolation of differentially expressed cDNA clones from the filarial nematode Brugia pahangi [PDF]

open access: yes, 1999
A cDNA library constructed from 3 day post-infective L3 of the filarial nematode Brugia pahangi was screened by differential hybridization with cDNA probes prepared from different life-cycle stages.
