| Abstract | ||
| Field study were conducted at Koysinjaq city –Erbil province during season 2013 to evaluate the effect of plant host on population density of lace bug, Monosteira buccata Horv, and susceptibility of three Salicaceae tree species, ( Populus nigra L.Populus euphratica Oliv.and Salix acmophylla B. ) to its infestation. Adults appeared in the mid May and their numbers increased until disappeared in the second week of December. The results of the ecological study indicated that the population density of insects under field conditions reaching its number peak in July and Augusts (3695 and 3580 insect) with infestation percent of 78.3 and 76.6 % on different host plant during the period of experimental. Results indicated that Villow trees, Salix acmophylla B, was the most susceptible species to infestation with average 878.7 insect, followed by Euphratic poplar , Populus euphratica Oliv. (537.5 insect), whereas the Black poplar ,Populus nigra L., was the least susceptible (166.2insect). | ||
