Abstract
In Egypt, Nezara viridula L is widely spread all over the country attacking a wide varieties of agricultural crops and many weed species. Therefore, an experiment was carried out at Sakha Agric. Res. Station Farm, Kafr El-Sheikh to survey the host plants of the insect as well as overwintering sites during the period from March ,1999 to March, 2000. The obtained results indicated that twelve field crops, ten vegetable crops and fourteen weed species were found harboring N. viriduia during the period of study. Six summer field crops (cotton, corn, rice, sunflower, soybean and mungbean) and five summer vegetable crops (okra, egg-plant, pepper, tomato and cowpea) received both adults and nymphs from March to December. The insect passed the winter as adults on six winter field crops (dover, faba bean, wheat, barley, flax and sugar-beet) , five winter vegetable crops (cabbage, cauliflower, potato, bean and peas), seven annual winter weeds (wild peas, wild mustard, wild chicory, milk thistle, grundsel, bunweed nettle goosefoot and chard) and four perennial weeds (balady grass, bermuda grass, typha and purslan) from November to March. The insect used these winter plant species as overwintering sites because the adults were only moving and feeding on these winter hosts without egg depositing . Chard and three annual summer weeds (hound's berry, burrweed and )ew's mallow) received both adults and nymphs from May to November. However, the gained results are of importance, as they are taken into account in planning programs of integrated pest management .
