 en Insecticidal Potential of an Orally Administered Metabolic Extract of Aspergillus niger check for this species in other resources on Chrysomya chloropyga check for this species in other resources (Green bottle fly) Larvae
ESSIEN J. P

Abstract

The insecticidal activity of Aspergillus niger check for this species in other resources IHCS-4 metabolic extract against Chrysomya chloropyga check for this species in other resources larvae was examined in vitro. The toxicity test revealed that 0.04 mg/g and 0.08 mg/g extract concentration significantly (P>0.05) affected the insect larvae, inducing 20% and 65% mortality respectively, within 24 hours. Larval growth was inhibited only at concentrations of 0.04mg/g or higher. Survivors of the toxicity treatment at 0.04mg/g and 0.08mg/g recorded significant reductions in weight over time. These observations have indicated the potential of A. niger as a simple, inexpensive and accessible source of bioinsecticide @JASEM
