Entomopathogens are significant natural enemies
for mosquitoes. We have investigated the adulticidal efficacies
of metabolites of Trichophyton ajelloi and Lagenidium
giganteum against Culex quinquefasciatus and Aedes aegypti
simultaneously. The T. ajelloi was grown on Sabouraud’s
dextrose broth medium at 25±2°C and relative humidity at
75±5% for 15 days. L. giganteum was grown in peptone yeast
extract glucose broth at 25±2°C and relative humidity 75±5%
for 15 days. The filtrations of metabolites have been made by
using Whatman-1 filter paper then with the flash chromatograph.
The bioassays were conducted as per theWorld Health
Organization’s methods and protocols (2006). In this significant …

Chrysosporium tropicum is a pathogenic fungus.
It is known to be an effective mosquito control agent. In the
present study, we have synthesized the silver and gold
nanoparticles using C. tropicum. These nanoparticles have
been characterized through Microscan reader, X-ray diffractometer,
transmission electron microscopy, and further
confirmed by scanning electron microscopy. The characterization
study confirmed the spherical shape and size (2–15
and 20–50 nm) of gold and silver nanoparticles. These silver
and gold nanoparticles have been tested as a larvicide against
the Aedes aegypti larvae. The larvicidal efficacy was noted
when performed against all instars of A. aegypti at six …

Abstract: Problem statement: Biosynthesis of nanoparticles using fungal cells is a novel approach to
develop biotechnological possess such as bioleaching and bioremediation. In the present study, an
effort was made to investigate the effect of physio-chemical parameters on the silver nanoparticle
formation with the fungus Chrysosporium tropicum Carmichael and Fusarium oxysporum Schltdl.
Approach: The possibilities to manipulating the geometry of silver nanoparticles by altering the key
growth parameters such as pH, temperature, concentrations and time have been explored. The effect of
AgNO3 with the cell free extract of fungi and time, temperature, pH with the formation of silver has
also …

Problem statement: Mosquito is a very common vector of several tropical diseases such as
malaria, filariasis, dengue and chikungunya. Till todate, many xenobiotics have been used to control
mosquito population and protect people from mosquito born diseases but increasing rate of resistance
against these xenobiotics is a major concern in the disease control management. In contrast, extensive
use of these xenobiotic may lead to cause opurtunistic disease like cancer. Therefore, biological control
can thus be an effective and environmental friendly approach, which can be used as an alternative to
minimize the mosquito population. Fungi and fungus-derived products are highly toxic …
