Abstract
Field experiments were conducted during Summer and Kharif 2024
at PAJANCOA & RI, Karaikal to investigate the seasonal incidence of insect
pests of proso millet and their relationship with meteorological parameters.
The peak incidence of shoot fly (12th MSW), pink stem borer (13th
MSW), leaf folder and flea beetle (12th MSW), aphids (14th
MSW), and earhead bugs (16th MSW) was observed during Summer 2024. In
Kharif 2024, peak incidence occurred at 38th - 43rd
MSW depending on the pest species. Correlation studies revealed that, in
Summer, shoot fly, leaf folder, and flea beetle populations were negatively
associated with minimum temperature, while pink stem borer and aphids showed
negative correlation with evening relative humidity. Earhead bugs exhibited a
positive correlation with both maximum and minimum temperature. During Kharif,
shoot fly showed positive correlation with temperature and negative association
with relative humidity. Minimum temperature positively influenced pink stem
borer, leaf folder, and flea beetle, whereas earhead bugs were positively
associated with relative humidity and negatively with maximum temperature. Multiple
linear regression analysis indicated that weather parameters significantly
influenced pest incidence, explaining about 56–94% of variation in summer and
59–80% in Kharif. The study enumerated the strong influence of climatic
factors on the regulation of pest dynamics in proso millet, providing a basis
for developing weather-based pest management strategies.
