Abstract Experiments were conducted at the farm of Faculty of Agriculture, Shebin Elkom and laboratory of Economic Entomology and Agricultural Zoology Department to study the eriophyid mites associated with three vegetable plants, five fruit trees, and two ornamental plants during the period from 2013/2015. Ecological studies: Ecological studies were performed for two successive seasons as follow: 1. Incidence studies indicated that 11 species of eriophyid mites belonging to 7 genera, both tomato and eggplant were infested with high number of Aculops lycopersici; artichoke plants with Eriophyes neocynarae; while fig was infested with Eriophyes ficus. As for fruit trees mango infested with three species, Aceria mangifera (High number), Meticulous mangifera (moderated number); and Cisaberoptus kenyae (High number); guava was infested with Eriophyes pyri while Aculus schelechtendali infested apple trees; citrus trees were infested with Phyllocoptruta oleivora with low number. As for ornamental plants, rare number of Eriophyes daturae infested Duturae plants, while albarnov was infested with high numbers of Aceria dioscoridis. 2- Population dynamics of eriophyid mite cleared that the lowest number of Aculops lycopersici was during April while maximum numbers were at the end of July, an eggplants lowest numbers were during March and the highest at mid of July. Eriophyes ficus average number was the lowest during the period from 30 August to the end of April, while the highest numbers were at the mid of July. Numbers of Meticulous mangifera were low during the period from January to April, while high numbers were collected during August, September and October months. Cisabroptus kenyae infested mango with high numbers, its maximum average numbers were during the period from mid November to mid December. guava trees eriophyid mite. |
