Abstract
Aphis gossypii
Glover causes various serious economic damages to many crops. Entomopathogenic
fungi like Metarhizium anisopliae have been proven as biological control
agents in controlling many pests. This study included testing the effectiveness
of two methods for preparing M. anisopliae filtrate in the mortality of A.
gossypii under laboratory conditions. Three replicates were used to test
three concentrations of the two factors: the autoclave sterilized filtrate and
the Millipore sterilized filtrate, in addition to the control treatment,
distilled water. The results showed that the autoclave sterilized filtrate was
superior to the Millipore sterilized filtrate for M. anisopliae, The
percentage of mortality increased with increasing concentrations and increased
in the treatment period, to be recorded at 100.00 and 83.00 % at the highest
concentration of nymph mortality in the filtrate sterilized with autoclave and
the filtrate sterilized with Millipore, respectively, compared with 70.00 and
53.30% at adults mortality at the same concentration after three days from
treatment. The results of this study, which took place under laboratory
conditions, supported the importance of using entomopathogenic fungi in several
ways. However, their field testing and effectiveness must still be verified
against other biological enemies.
