Population Densities of Apricot (Hyalopterus Pruni) Trees Lesions

Abstract

The study was conducted at the University of Baghdad / Al-Jadriya / College of Agricultural Engineering Sciences to calculate the population densities of Apricot tree pests for a whole year, and the results showed that the pests were from the leaves of the Apricot Hyalopterus pruni, from the green peach Myzus persicae and Tetranychus urtia, and the results showed the highest density of an apricot insect, which was 32 nymphs / cm2 from the vegetable leaf, and the lowest was 1 nymph / cm2 from the vegetable leaf. The highest density of the two-spot mite is 27 nymphs / cm2 of the plant leaf. The results indicate the presence of the predator, the aphid and the seven-point ladybird.
