ABSTRACT
The studies were carried out to determine the percentages of infestation by Chiloagammemnon (Bles.) infested sugarcane crop at five Governorates of middle and Upper Egypt (Mimya; Sohag; Quuna; Luxor and Asswan) in 2017 and 2018 sugarcane (C. 9/54 commercial Varity) seasons. During harvest period, in February, several sample each of approximately 200 plants where cleaned and carefully examined where the numbers of broken and infested mind recorded. Data concerned % infestation which include (infested and broken mind) indicated three level of infestation by C. agamemnon . first level infestation occur in the two season of study at Minya (Abu Qirqas) and Sohag (Girga) governorates where the % infestation were 5.66 and 7.4 % in the first season and were 6.67 and 7.27% in the second season ,respectively. Data indicated significant lower in the infestation at Minya and Sohag than all the other localities of studies.The second level of infestation is the moderate one which include localities of NagahHammadi: Dishna and KomOmbo recorded percentages of infestation 9.46: 9.52 and 9.19 in the first season for the three localities, respectively. The same trend occur in the second season of study where the recorded % infestations were 9.58: 9.82 and 9.28 % by means of 714: 843.75 and 867 , for the three localities, respectively.the highest % infestation in both of the two seasons of study occurs at Quus: Armant and Edfo. The obtained results concerning the % infestation of first season of study, resulted in13.51 and 13.63% infestation at Quus in the two seasons, respectively. Plants of Armant localities, came in the second order among category of high infestation where the recorded numbers of infested mind and broken mind were 3463 and 199, respectively, by 11.63% infestation in first seasons. While in the second season they were 4171 and 239 by 11.76 % infestation, respectively.Edfo, occupied the third order of high infestation by 10.33% infestation in the two years of studies. Insignificant deference could be observed between the infestations in the three localities of Quus: Armant and Edfo. Also, such data, indicated significant difference between infestations at Quus: Armant and Edfo with all other localities.
