Abstract

This study aimed mainly to estimate the resistance of the cotton leafworm Spodoptera littoralis to several bioinsecticides Agerine 6.5% WP, Protecto 9.4 %WP biotect 9.4 %, wp Dipel 2x 6.4% WP, Dipel Df 5.4 % WG and two other bioinsecticides, Emamectin benzoate (Radical 0.5 %) EC against Spodoptera littoralis that all field strains the tested bioinsecticides used against cotton leafworm S. littoralis were calculated for both susebtable and field strains collected from six governorates namely Sharkia, Dakahlia, Behera, kafr- Elshek, Fayuom and Beni- swef in the cotton season 2019. The resistance ratio fluctuated from very low resistance to low resistance in some governorates to others except low of governorates RR indicated high resistance. tested IGR, s used against cotton leafworm S. littoralis were calculated for both susebtable and field strains collected from six governorates namely Sharkia, Dakahlia, Behera, kafr- Elshek, Fayuom, and Beni-Swef in the cotton season 2019. showed no resistance in all tested IGR, s for all Governorates, except some Governorate in some IGR, s

埃及棉季沿海夜蛾田间种群对杀虫剂的抗性和药效变化

本研究主要评价了棉花叶虫对Agerine 6.5% WP、Protecto 9.4% WP、bitect 9.4%、WP Dipel 2x 6.4% WP、Dipel Df 5.4% WG等几种生物杀虫剂的抗性。对2019年棉花季从Sharkia、Dakahlia、Behera、kafr- Elshek、Fayuom和Beni- swef 6个省采集的所有用于防治沿海夜蛾的生物杀虫剂的易感和田间菌株进行了计算。在一些省份，抗性比从极低到低波动，而在其他省份，抗性比低表明抗性高。对2019年棉花季从Sharkia、Dakahlia、Behera、kafr- Elshek、Fayuom和Beni-Swef 6个省采集的棉花叶虫敏感品系和田间品系的IGR检测值进行了计算。除某些IGR中的某些省份外，所有省份检测的所有IGR均未显示耐药性
