An experimental trial was carried out to know the time required to complete the life cycle of maize cyst nematode, Heterodera zeae on sweet corn (var.- Madhuri). Life cycle studies revealed that second stage larvae of maize cyst nematode, H. zeae are the infective stage and penetrated sweet corn roots at 48 hours of inoculation. After penetration, the third stage larvae were observed on the 6th day of inoculation. Fourth stage larvae and adult females were observed at 13th and 19th day after inoculation, respectively. The mature cyst of H. zeae was observed on the 25th day after inoculation. Thus, the life cycle of maize cyst nematode, H. zeae on sweet corn took place in 25 days after inoculation of second stage larvae.
