Abstract

Two experiments were conducted to study the effects of temperature on hatching of cysts of Heterodera ciceri and on the infectivity of its second-stage juveniles to chickpea seedlings. Hatching tests showed that the emergence of juveniles was substantial at 10, 15,20, and 25°C and negligible at 5 and 30°C. Maximum emergence was obtained at 25°C (31%), which was not significantly different from that of 200 e (25%) and 15°C (16%) at P=0.05. Significantly more second-stage juveniles invaded the roots of chickpea seedlings at 10. 15 and 20°C than at 25 and 30°C.
