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).
