| Abstract | ||
| The study indicated that adults of corn stem borer Sesamia cretica Led. Were found through out the years in sugar cane field. The highest adult intensity was in the middle of June. While the lower was during January. The comparison among the hosts plant declear that yellow corn was most preferring to adults of stem borer during to lying egg. The highest average was 138.33 egg for with percentage reached 51.94% while in the variety of sugar cane CP2/68 reached 48.33 egg , with a percentage 18.15% . the highest. Infestation in the field was record in the verity CP52/68 it reached 24.9%. the statistical analysis showed that increase of Nitrogen , Water including leaf area and stem diameter causes increased the infestation and , decrease chlorophyll and fibers. The mixture of selecron with match and Dimilin insect growth regulators cause best results to control of larves and adults compared with Diazinon 60%. | ||
