Oct 07, 2014·Females of several mosquito species have evolved obligatory blood-feeding to supply amino acids and other nutrients necessary for egg development, providing a mechanism for the spread of many devastating diseases in humans. The mosquito-specific microRNA (miRNA), miR-1174, is significantly upregulated post blood meal and specific to the female mosquito midgut, suggesting a …

Apr 12, 2011·For example, water uptake by oocytes occurs in mosquitoes during egg development. The weight of an Aedes aegypti egg can increase from 5 to 12 μg due to the water influx. Although the whole process lasts 10–16 h, the majority of water uptake occurs within the first 2 h postoviposition ( 5 ).

Mosquitoes are popularly referred to as ‘flying syringes and ‘public enemy number one’ are the worst enemy of mankind since dawn of time and act as a vector of several dreadful diseases. Mosquito-borne diseases are major human and animal health problem in all tropical and subtropical countries.

Biodistribution of degradable polyanhydride particles in ...

Sep 08, 2020·Particle uptake and biodistribution were explored both in vitro in mosquito cell culture, and in vivo by exposing adult mosquitoes to rhodamine B (Rho)-labeled polyanhydride particles via three field-relevant routes (treated-surface contact, topical application, and exposure to treated food).

Uptake of 36 Cl Toxaphene in mosquito fish, Gambusia ...

Uptake, penetration, and storage of insecticides has been studied most extensively in mosquito fish, G„ affinis. Ferguson et al. (19 66) studied the dynamics of endrin uptake and release in mosquito fish. In this series of well^ planned experiments, they demonstrated that the major source of endrin uptake was contaminated water rather than

Factors affecting transmission of Wuchereria bancrofti by ...

Abstract. Ingestion of Wuchereria bancrofti microfilariae (mf) from humans by 639 Anopheles gambiae, 557 An. arabiensis, 117 An. melas and 9 An. funestus was investigated. The mf densities in blood fell into 3 groups; 0–32mf/ml, 107–122 mf/ml and 421–1140 mf/ml. In An. gambiae and An. arabiensis percentage of mosquitoes ingesting mf was strongly associated with mf density in host blood ...

Aedes aegypti Mosquitoes Use Their Legs to Sense DEET on ...

May 06, 2019·To ask whether DEET can inhibit Ae. aegypti mosquito sugar feeding, we used the CAFE assay [14, 15, 16] to offer fasted animals a choice between drinking either 10% sucrose or 10% sucrose mixed with either 1% DEET or substances known to be bitter (lobeline or quinine) (Figure 1A). The selection and concentration of bitters throughout this study was guided by classic work from …

Disruption of XDH by allopurinol or XDH1 by RNA interference significantly affected mosquito survival, causing a disruption in blood digestion, excretion, oviposition, and reproduction. XDH1-deficient mosquitoes showed a persistence of serine proteases in the midgut at 48 h after blood feeding and a reduction in the uptake of vitellogenin by ...
