الملخص EN

During 1995-1997, a study on citrus leaf miner (phyllocnistis citrella stainton) population dynamics was carried out.

in 1995, no differences in infestation level were observed on four citrus species (grapefruit, lemon, washington navel, clementine), with highest infestation level in July.

during 1996 and 1997, and irrespective of citrus species, infestation with the citrus leaf miner was rare on he spring flush.

the leaf miner was rare on the spring flush, low on the fall flush, and it peaks during summer (July and august) reaching 100%.

the highest rate of parasitism was in august (73%).

the following parasitodies have been isolated and identified: ratzeburgiola incompleta, cirrospilus sp.

nr lyncus, cirrospilus ingenus, semielacher petiolatus and neochrysocharis sp.
