Abstract
Rice is one of the most important staple foods for more than three billion people allover the world. In Egypt, rice is attacked mainly by rice stem borer [Chilo agamemnon], leaf miner [Hydrellia presternalis], Bloodworms [Chironomus spp.], leafhoppers, planthoppers and stink bug [Nezara viridula ] This study was carried out at the experimental farm of Rice Research and Training Center (RRTC), Sakha Agricultural Research Station during two successive seasons; 2017 and 2018. Egyptian Hybrid 1 was sown on May 5th and Sakha 101 was sown on June 20th, and transplanted one month later. The insects and their natural enemies were collected and their population fluctuations were monitored using 50 double stroks by sweep net, 10 pitfall traps, visual records, as well as dissection of rice hills. The occurring arthropods in rice plots were recorded..
