Abstract

The WALNUT APHID is regarded as a main pest of WALNUT trees throughout the world including Iran. The POPULATION FLUCTUATIONS and identification of it's NATURAL ENEMIES was studied in Khalatpoushan Agricultural Research Station and a region of Oskou during year 1997 and 1998. Population samplings in two regions were made at weekly intervals when 50 leaflets were randomly taken from 10 selected trees at 4 directions and from internal parts of the tree canopies. The exact number of lavae, adults and existing NATURAL ENEMIES were determined later on the laboratory. Counts of the actively moving predators were made in situ using a hand lens before removing the leaflets. Samplings for recognition of predators and parasitoids were also done at 3-day intervals, twice during the day in the morning and afternoon using forceps, aspirator and brushes and/or by means of beating method. It was revealed that the aphid populations reached higher densties in Khalatpoushan on 2nd of July in 1997 and 25th. of June in 1998, being 49±4.7 and 8.4±1 aphids per leaflet, respectively. Also, high density aphid populations in Oskou reached on 19th. of June in 1997 and 28th. of May in 1998, with a mean density of 21±3.1 and 25.52±3.06 aphids per leaflet, respectively. However, the results showed significant differences between population densities in Khalatpoushan in contrary to Oskou region for the two successive years. The NATURAL ENEMIES population were also at higher densities in 1997 and the difference appeared to be significant (P <0.01). NATURAL ENEMIES at both regions during the two years, were identified to be 4 Coleopteran, 1 Neuropteran, 2 Hemipteran and 1 Dipteran species and some species of spiders in 2 families. Also, in Hymenoptera 1 parasitoid and 2 hyperparasitoids were determined.
