Abstract
The present study was conducted at the farmer’s field at vallampadugai
village near Annamalai University, Chidambaram (Tamil Nadu), India, to
investigate how abiotic factors affect the seasonal occurrence of the aphids (A.
gossypii) on brinjal plants. The study focus on the aphid population during
the Kharif-2022 (June to September) and Rabi-2022-23 (November to March)
seasons. A. gossypii were found from the 24th to the 39th
standard meteorological weeks (SMWs) in the Kharif season and from the 47th
to the 10th SMWs in the Rabi season. The population increased
gradually and reached to peak in the second week of August with population of
19.26 aphids in Kharif 2022 and fourth week of February with population of
47.86 aphids in Rabi 2022 -23 respectively. The population of this pest started
to be declined in fourth week of August (1.33 aphids) in Kharif and declined to
the level of 8.06 aphids in the second week of December in Rabi season. The
aphid population gradually decreased with fall in the temperature during both
the seasons.
