Abstract

Laboratory and field assessments were carried out to determine
the efficiency of three biological control agents Metarhisium
anisopliae, Verticillium lecanii and Beauveria bassiana locally isolated
from dead pupae and adults medflies Ceratitis capitata against adults
of C. capitata. Serial dilutions were prepared at 105,106 and 107 spores/
ml and applied as poisonous suspension for 5,7 and 10 days.
Increased mortality percentages were obtained for the three
agents chosen, at 710 spores / ml, being 92.4, 80.8 and 76.0 %,
respectively after 10 days. Calculated LC50 after 72 hr. were 1.4 x 102,
4.6 x 102 and 2.4 x 103 spores / ml, respectively. A new insect spores
bait trap was designed for field experiments, and applied in the field
trails in Ibshway district, Fayoum Governorate, Egypt on apple tress
Malus pumila. In such trails, double concentrations of the
aforementioned once were used. Higher percentages of mortality were
obtained from April to September. Reduction percentages of 93.2, 85.0
and 84.9% at the concentration 2 x 107 spores/ml for M. anisopliae, V.
lecanii and B. bassiana, respectively.
