Description |
Biology of sesamum lear webber and pod borer, Antigastra catalaunalis Dup. under lab conditions was studied on leaves and pOds separately and it showed no significant difference in any stage of life cycle. The duration of each stage was as follows: Egg 2.9 to 3.0 days, larval period 10.78 to 11.20 days, pre-pupal period 1.22 to 1.37 days, pupal period 4.53 to 4.82 days reared on leaves and pods respectively. The total life cycle took 19.43 days on leaves and 20.39 days on pods. The average sex-ratio between females and males was observed to be 1.3 a 1.0 reared on leaves and 1.6 : 1.0 on pods. Efficacy of different insecticides to control pest complex of seaamum showed highest reduction in the larval popu1ation (75 .3'7") by quinalphos 0.05 per cent which was on par with monocrotophos 0.05 per cent, tenvalerate 0.4 per cent dust and carbosulfan 0.05 per cent. Monocrotophos 0.05 per cent, diflubenzuron 0.05 per cent + endosulfan 0.07 per cent and quinalphos 0.05 per cent were highly effective in controlling aphid population. Monocrotophos 0.05 per cent was found most effective in the control of thrips with 85.63 per cent population reduction. Quinalphos 0.05 per cent spray was rated as first in over all cont~ol of sesamum pest complex with highest yield of 344 kg ha-1. The 1 yield level with fenvalerate 0.4 per cent dust gave 340 kg na- and it was followed by monocrotophos 0.05 per cent treatment with 335 kg ha-1. The ditlubenzuron 0.05 per cent + endosulfan 0.07 per cent also showed its efficiency in increasing the yield 320 kg ba-1. Among the thirty sesamum varieties tested under field conditions tof their resistance and susceptibility, the variety Gouri was tound highly resistant and JLSC-8 found susceptible to leaf webber and pod borer, aphids and thrips population. The hisbest yield was recorded in var1ety1 Gouri (181 kg ha-1) and the lowest in JLSC-8 (25 kg ba•l). |
