Abstract
The study conducted in Dongargarh, Chhattisgarh, India revealed
significant seasonal variations in the abundance and diversity of insect
species associated with paddy cultivation. Data collected over a 12-month
period showed that insect populations—both pests and beneficial species—were
highest during the monsoon season due to favorable climatic conditions such as
increased rainfall, humidity, and moderate temperatures. Key pest species
including Nilaparvata lugens (brown planthopper), Scirpophaga
incertulas (yellow stem borer), and Cnaphalocrocis medinalis (rice
leaf folder) showed peak abundance in monsoon, posing a considerable threat to
crop yield. Beneficial predatory insects like ladybird beetles (Coccinellidae)
and dragonflies (Odonata) also increased during this period, though they
remained outnumbered by pests. Statistical analysis confirmed a strong positive
correlation between insect abundance and rainfall (r = 0.78), followed by
humidity (r = 0.72) and temperature (r = 0.65). The lowest insect abundance was
recorded during winter. These findings underscore the need for season-specific
integrated pest management (IPM) strategies to mitigate pest outbreaks and
enhance sustainable rice production in the region.
