The rice leaf folder population acquired 3.703, 3.386, 0.6035 and 0.6350 fold resistance in kharif season and 4.249, 3.559, 0.5605 and 0.6630 fold resistance in rabi season to cartap hydrochloride, fipronil, triazophos and lambda cyhalothrin respectively at LC90** in comparison with field recommended concentrations. The present study clearly exhibited profound influence of insecticide usage in resistance development. Less used chemicals recorded low resistance factor. However, the effectiveness of new molecules was in the order of lambda cyhalothrin, cartap hydrochloride, triazophos and fipronil respectively at SD50** level in both kharif and rabi seasons. While at LD90** level it was lambda cyhalothrin, fipronil, triazophos and cartap hydrochloride in kharif season, while in rabi season it was lambda cyhalothrin, triazophos, fipronil and cartap hydrochloride. Regarding the conventional insecticides, the larvae were found resistant to cypermethrin with no trace of resistance development to chloropyriphos and endosulfan. M.Sc (Ag), 2008 “Studies on seasonal incidence and Evaluation of different spray schedules against spotted pod borer, Maruca vitrate (Geyer) (Pyralidace: Lepidoptera) on blackgram” Student : Chitti Babu Giddi Major Advisor : Dr. (Mrs.) T.Madhumathi Department of Entomology A field experiment entitled “Studies on seasonal incidence and evaluation of different spray schedules against spotted pod borer, Maruca virata (Geyer) (Pyralidae: Lepidoptera) on blackgram” was conducted at Agricultural College farm, Bapatla during rabi 2007- 08. The larval incidence of M. vitrata started during the third week of December (15.12.2007) i.e.at the early flowering stage of the crop (30 days after sowing) and reached a peak level (37 larvae per %0 plants) during the second week of January (12.01.08) coinciding with the maximum flowering stage of the crop. Among the chemical schedules (F1*), the profenofos schedule (C3*0) was found effective which recorded the lowest mean number of M. vitrata larvae (1.24) and damaged flowers/pods (1.61) per five plants. Among the spray interval schedule (F2*) the four days interval spray schedule (D1*) was found effective and has recorded the lowest number of M. vitrata larvae per five plants (0.80) and mean number of damaged flowers./pods per five plants (0.93). The interaction between the profenofos schedule and four days interval spray schedule i.e. C3D1** was found effective and has recorded the lowest mean number of M. vitrata larvae (0.73) and damaged flowers /pods (0.67) per five plants. The grain yield was highest (2.08 kg per plot) in the profenofos schedule and in for days interval spray schedule (2.10 kg per plot) as well as in the interaction between profenofos and four days interval spray schedule (C3D1**) i.e. 2.e. 2.40 kg per plot. However, the CB ratio was highest in neem schedule and ten days interval schedule (1:208) because of low cost of plant protection. M.Sc (Ag) ,2008
