Abstract EN

The Parasite Cirrospilus sp.

nr.

lyncus (Walker) has been reared on the pure sour orange seedlings infected by citrus leafminer within separate wooden cages in Lattakia Insectary for rearing Natural Enemies during both years 1996-1997.

Some of the biological parameters were studied in the field condition and were shown that its development passes in the following phases: Oviposition period, larval stage and the pupal stage and these were 3.55+0.13 days 2.70+0.18 days, 4.90+0.40 days, under summer conditions, respectively.

The life cycle of Cirrospilus sp.

nr.lyncus from egg to adult emergence was 11.15+0.60 days under summer conditions and 22.9+2.08 days in winter conditions.

The adult longevity lasted 27.07+1.26 days when fed on honey mixture and 4.47+0.38 without any feeding, During growth season of 1997, the presence rate of the parasite Cirrospilus sp.

nr.

lyncus (Walker) of the total parasites was reached in August 73.53%, and its average throughout the same growth season was 60.31.
