ABSTRACT
This study was carried out to compare the infestation ratio of Pink Bollworm, PBW (Pectinophora gossypiella Saund.) and Spiny Bollworm, SBW (Earias insulana Boisd.) on blind bolls in Harran (Sanliurfa), Kiziltepe (Mardin) and Bismil (Diyarbakir) Plains during 2002-2003. The blind bolls were collected from cotton fields at the end of the harvest and the infestation ratio with these pests was determined. Infestation ratio, the numbers of PBW and SBW larvae of that three plains were compared with each other. At the end of this study, Harran Plain was recorded as the most infested area with these bollworms. The population of PBW larvae was higher than that of SBW in Harran Plain. In contrast, the population of SBW larvae was higher than that of PBW in Bismil and Kiziltepe Plains. The infestation ratio with these bollworms of collected blind bolls in Harran, Kiziltepe and Bismil Plains in 2002-2003 was found as, 73.71, 65.28, 11.57, 22.00, 6.28 and 6.71%, respectively. In addition, PBW was recorded for the first time Kiziltepe and Bismil Plains with this study
