Penetration was not affected by temperature but, migration and post-penetration inside the root tissue were influenced by temperature. At 27±1°C, M. incognita second stage juvenile (J2) took 5 days to reached stele region followed by 31±1°C and 23±1°C (7 days) while, at 21±1°C, it took 10 days. Multiplication of M. incognita was greatly affected by temperature. Maximum number of galls per root system (119.6), number of egg masses per root system (275.2), number of eggs per egg mass (343.6), final nematode population (1335.2) and reproduction factor of nematodes (2.67) was observed at 27±1°C followed by 31±1°C, 23±1°C and 21±1°C respectively.

Keywords: Second stage juvenile (J2) Meloidogyne incognita, Penetration, Multiplication, Temperature
