This study on species composition of sugarcane shoot borers was carried out in the South Gujarat Agroclimatic Zone II. The results revealed the infestation of two species of shoot borers viz., Sesamia inferens (Walker) and Chilo sacchariphagus indicus (Kapur) in the early stage of sugarcane. Maximum incidence of S. inferens (77.56, 88.24 and 88.72%) was observed compared to that of C. sacchariphagus indicus (22.44, 11.76 and 11.28%) during 2015-16, 2016-17 and 2017-18, respectively, indicating that S. inferens (84.84%) is dominant over C. sacchariphagus indicus (15.16%) in overall incidence.
