Abstract
Two field experiments were conducted during Kharif 2020 and Rabi
2020–2021 at Ariyalur district, Tamil Nadu, to evaluate the bioefficacy of
newer insecticides against major insect pests of groundnut and their safety to
natural enemies. Among the treatments tested, chlorantraniliprole 18.5 SC at
100 ml ha⁻¹ was most effective against the groundnut leaf miner, Aproaerema
modicella, recording the lowest leaf damage of 4.03 and 3.05 per cent
plant⁻¹ with 66.01 and 71.92 per cent reduction over untreated check during
field experiments I and II, respectively. Against tobacco leaf caterpillar, Spodoptera
litura, flubendiamide 39.35 SC at 100 ml ha⁻¹ recorded the lowest larval
population of 0.70 and 0.68 larva plant⁻¹ with 82.76 and 83.18 percent
reduction over control. Higher populations of predatory coccinellids and
spiders were observed in chlorantraniliprole-treated plots, indicating relative
safety to natural enemies. Chlorantraniliprole 18.5 SC at 100 ml ha⁻¹ also
recorded the highest pod yield (3730.30 and 3780.33 kg ha⁻¹). The study
revealed that chlorantraniliprole, flubendiamide, and pymetrozine are effective
and comparatively safer options for integrated pest management in groundnut
ecosystems.
