摘　　要：In this study, some Eriophyid mite species showing different morphological characters and host-plant symptoms were obtained. Five mites species collected from different localities in Khartoum State （Sudan） during the period （2002-2003） which classified under family Eriophyidae from different hosts were selected and examined carefully. These were recognized as Cisaberoptus kenyae （K.） on Mango Mangifera indica, Acalitus hassani （K.） onArrak Salvadora persica, Aceria balanites （Massee） on Heglig Balanites aegyptiaca, Colomerus vitis on Grape Vitis sp. （for the first time in the Sudan） and Eriophyes tulipae （K.） on Onion Allium cepa and garlic Allium sativum respectively. The remaining six eriophyid mites were not completely described but designated as Eriophyes sp. 1, 2, 3, 4, 5 and 6 on Sidir Ziziphus spina, Aradeib Tamarindus indica, Harazz, Acacia albida, Talha Acacia seyal var. seyal, Seyal Acacia tortilis var. raddiana and Mormeet Pergia capensis respectively. The response of 12 different plant species infested artificially with Cisaberoptus kenyae （K.）, Acalitus hassani （K.） and Eriophyes tulipae （K.） were studied after two months of infestation. The results showed that onion and garlic plants were severely infested with Eriophyes tulipae （K.） while tomato was found to be susceptible for Cisaberoptus kenyae （K.） and Acalitus hassani （K.） showing moderate infestations. On the other hand, sorghum and wheat infested with Eriophyes tulipae （K.） showed moderate and light infestations respectively. On the contrary, mite infestations were not detected on the rest of plant species. The degree of infestation of Eriophyid mites species on different test plants, measured by symptoms appeared on plant leaves.
