ABSTRACT

The egg parasitoid Anaphes fuscipennis Hal. is recorded for the first time in Egypt on eggs of the Egyptian alfalfa weevil. The parasitoid was reread under the laboratory conditions; 18, 22 and 80C constant and 1 6/220C fluctuated temperatures. Results indicated that the parasitoid completed its life cycle within 17 days at the room temperature (19±3oC), however, the longest oviposition period (13.7 days), the highest fecundity (82.3 eggs/female) and the longest longevity (15.3 and 10.0 days for females and males, respectively) were recorded for the parasitoid reared under the lowest temperature (18°C). Sex ratio calculated from field samples was 2.5:1 female to male. Five generations of this parasitoid were reared in the laboratory.
Field samples were collected from January 20 to May 5. Peak of parasitism (52.6% and 48.3%) were recorded on April 4 and March 20 in the first and second seasons, respectively. Yearly means of parasitism were 12.8 and 15.7%, respectively.
