Abstract
The present study investigates the
relationship between environmental conditions and abundance of beneficial
insects associated with major Rabi crops. The research was conducted during two
consecutive Rabi seasons (2021–22 and 2022–23) across multiple crop fields in
Dhod tehsil to assess how variations in abiotic factors such as temperature,
relative humidity and rainfall affect insect populations. The findings revealed
that insect populations decreased markedly during the cold winter months
(December–January), while a significant resurgence was recorded from February
to March as temperatures increased and moderate humidity conditions prevailed.
Episodic rainfall and cooler, humid conditions during mid-winter were found to
favor pest outbreaks such as aphids, which subsequently supported higher
populations of natural enemies including coccinellids and syrphid flies.
Therefore, the study reinforces temperature and humidity as primary drivers of
insect population behavior, while rainfall and related atmospheric factors
further modulate species-specific responses.
