Abstract

Life cycle of Meloidogyne incognita in resistant chili  variety, POP was compared with the  susceptible variety, Hua Ruea by observing and comparing the rate of growth and development between the first and the second generations of second stage juveniles (J2). The results show that the second stage juveniles initially infected root caps of chili cultivar POP and Hua Ruea in 4.67 days and 19.33 hours, respectively, after nematode inoculation. In addition, the development times from the first to second generation were 42.33 days for cultivar POP and 26.66 days for cultivar Hua Ruea. The numbers of nematodes infecting root system were 31.67 for POP and 102 for Hua Ruea.
