Abstract

The efficiency of entomopathogenic nematooes on the adults of roo I peach borer.
Capnodis carbonaria ( Klug.) was studied in the laboratory and under semi-field
conditions. In the first experiment, the percentage of mortalitis were recorded when
three nematode species, i.e., Heterorhabddis bacteriophora , Sieinemema
carp < /em>ocapsae and Sieinemema. feltiae were use . The percentage of mortalities after
two and three days were 88, 100,76 and 92,100 and 88% for the three nematode
species, respectively. In the second experimenl S. carpocapsae was tested against
adults of C. carbonaria under semi-field conditions. The results obtained for %
mortalities were 5, 0, 16, 50 and 20 when the r ematode suspension used at 1000,
2000, 4000 and 8000 jovinoides I ml, two days after treatment, respectively. The
respective the percentage of mortality after foul days were 9.5, 11, 25, 75 and 9%.
The percentages of adult exit two and four days after treatment were 60, 56.7, 60, 60,
83.3; 70, 60, 66.7, 66.7 and 83.3 for the Ioi.r used nematode concentrations,
respectively.
