Abstract

S. graminum (Rondani) activity on wheat at Fayoum
Governorate was evident from the 1st week of Feb. to mid May with
two peaks. The first peak of infestation occurred at the early of April,
with 90 and 49 aphids/10 plants during 2000/2001 and 2001/2002
seasons, respectively. Also, five species of predators and three species
of parasitoids were recorded in association with this aphid.
C.undecimpunctata and C.carnea were the dominant predators during
the activity period from mid Mar. to mid April. On the other hand the
parasitoids, Aphidius sp. was the most common species, followed by
Aphelinus sp. and Diaeretiella rapae. The major weather factors
(max. temp., min. temp. and RH.) showed insignificant effect on
population of aphid , predators and parasitoids.
