Abstract
The effect of the various weather parameters on the growth and
development of the sorghum shootfly were studied by sowing the crop at six
different sowing dates so as to expose it to varied meteorological conditions.
Weather parameters, three days prior to egg laying play a deciding role in
influencing fly activity.
Egg laying had a correlation coefficient of + 0.752 with maximum
temperature, - 0.914 with minimum temperature, - 0.413 with maximum relative
humidity, - 0.841 with minimum relative humidity, + 0.805 with bright sunshine
hours and - 0.679 with rainfall intensity, while adult population denoted a
correlation coefficient of + 0.863 with maximum temperature, - 0.683 with minimum
temperature, - 0.638 with maximum relative humidity, - 0.73 with minimum relative
humidity, + 0.78 with bright sunshine hours and - 0.652 with rainfall intensity.
Dead heart formation did not have any direct correlation with meteorological
parameters but showed high correlation coefficient of + 0.962 with egg laying
and + 0.831 with adult populations, which were in turn related to the
meteorological parameters and as such dead hearts produced were indirectly
influenced by weather parameters
