Abstract
Earias insulana,
a type of cotton bollworm belonging to the Noctuidae family of Lepidoptera, is
widely regarded as a significant threat to corn crops worldwide. The damage it
causes is extensive, leading to substantial losses in terms of both quality and
quantity of Okra harvest. The aim of this investigation was to evaluate the effectiveness of spores
from entomopathogenic fungi (EPF) and silver nanoparticles against E.
insulana in a controlled laboratory setting. Various concentrations were created
using Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii. The
mortality rate of E. insulana ranged from 55% to 80% in each concentration
in larvae within a span of six days. Among them, B. bassiana and M.
anisopliae demonstrated superior efficacy compared to V. lecanii. B.
bassiana spores exhibited an enhanced ability to cause larvae mortality,
resulting in an 80% mortality rate, which showed a considerable increase compared to the control group.
Additionally, when exposed to B. bassiana, 75% of the pupae experienced
mortality within six days, while the percentages for M. anisopliae and V.
lecanii were 68% and 62%, respectively. Thus, it can be concluded that B.
bassiana exhibited greater effectiveness against E. insulana as
compared to M. anisopliae and V. lecanii.
