Abstract
Starch gel electrophoresis of P. xylostella from Benguet and Cabuyao at different developmental stages showed three banding patterns referred to as ESTP/ESTP for single fast band, EST/EST• for single slow band and EST'/EST• for both fast and slow bands. Among the Benguet strains, EST•/EST• were observed from first to third instars and adult, EST'/ESTT and EST•/EST• in both fourth instar and Pupa, and ESTIVEST• at all developmental stages. Among the Cabuyao strains, ESTT/EST'e were observed from first to third instars, together with EST•/EST•at pupa, and ESTP/EST• at all developmentals stages except at the adult where only EST•/EST•appeared. Protease banding patterns were also observed. Prot-2 was predominant in the Benguet P. xylostella population.
