Abstract
Studies on role of predators, other bioagents and cutting management in control of lucerne pests and breeding biology of one of the chief predatory species Sturnus Pagodarum Gmelin were carried out at Anand Campus of Gujarat Agricultural University, during 1990-91. The mean number Heliothis larval population was non-significant between T1 and T2. But population was minimum in T2 as compared to T1 at the time of harvesting. The green fodder was higher in T1 than T2. The Heliothis egg density varied throughout the year. Higher egg density in winter was attributed to both low maximum and minimum temperature and low % RH (Av.). While in summer, low egg density was due to high maximum °C temperature, whereas larval population remained constant throughout the year.
