Abstract
The evaluation of novel insecticides for their efficacy against thrips infesting chilli, Capsicum annum L.” was undertaken at Vegetable Improvement Scheme, Central Experiment Station, Wakawali under Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli during the Rabi, 2023-24 and Rabi, 2024-25. Experiment was laid out in Randomized Block Design with nine treatments and three replications and 14.4 m2 treatment plot area of size 6.0 m x 2.4 m. Three foliar sprays of the insecticide treatments viz., broflanilide 300 g/l SC (@ 0.0037%), cyantraniliprole 10.26% OD (@ 0.0123%), emamectin benzoate 05% SG (@ 0.0020%), fluxametamide 10% w/w EC 0.0080%), isocycloseram 9.2% w/w DC (@ 0.0110%), flubendiamide 19.92% + thiacloprid 19.92% w/w SC (@ 0.0159%), profenofos 40% + fenpyroximate 02.50% w/w EC (@ 0.0850%), emamectin benzoate 5% w/w + lufenuron 40% w/w WG (@ 0.0054%) were applied at fortnight interval initiating the first when sufficient thrips incidence was noticed at 45th days after transplanting along with Untreated Control. Pooled data recorded at before and after foliar spray revealed that the pre count thrip population was non-significant ranging between 5.48 to 8.09 per three leaves per plant. During fortnight interval, the treatment with isocycloseram 9.2% w/w DC (@ 0.0110%) found most effective and recorded thrips in range of 0.96 to 3.50 per three leaves per plant and found on par with broflanilide 300 g/l SC (@ 0.0037%) in which thrips ranges from 1.10 to 3.61 and flubendiamide 19.92% + thiacloprid 19.92% w/w SC (@ 0.0159%) from 2.36 to 3.98 thrips per three leaves per plant. In untreated control, it varied in the range of 7.96 to 8.30 per three leaves per plant.

Introduction
Among the stresses responsible for the lower yield, damage done by biotic stress by insect pests holds a major share.Tthe yield losses caused by chilli thrips, Scirtothrips dorsalis (Hood) and chilli aphid, Myzus persicae (Sulzer) are ranges from 50-90 percent and 40-70 percent in chilli crop, respectively (Venkateshalu et al., 2009) [18] . Also, Ahmed et al. in 1987 [1] reported that the yield losses due to thrips and mites are estimated to the tune of 50 percent. Sucking pest complex attack on different crop stages and causes "Churda murda or leaf curl". In sucking pest complex, chilli thrips, Scirtothrips dorsalis Hood, is a serious pest on chilli in India was documented by Ananthakrishnan (1971) and Krishna et al. (1996) [2,12] . Chemical pest control is the use of pesticides to eliminate pests. These pesticidal solutions are easily available, easy to use and very effective than any other methods. Efficacy testing of novel insecticides against chilli pests is useful for determining which new insecticides are most effective in controlling pests, allowing for the development of more targeted and sustainable pest management strategies. Hence, an attempt is made to study the efficacy of the important novel insecticides against thrips infesting chilli. to 8.43 (8.36, 8.26, 8.34, 8.43, 7.99 per three leaves per plant at 1 st , 3 rd , 7 th , 10 th , 14 th DAS, respectively).

Percent reduction
Percent reduction in thrips infesting chilli was recorded maximum in treatment isocycloseram 9.2% w/w DC (@ 0.0110%) which found most promissing for thrips control and also found on par to broflanilide 300 g/l SC (@ 0.0037%) as well as flubendiamide 19.92% + thiacloprid 19.92% w/w SC over untreated control and the reduction of thrips was noted 72.37, 70.69, 67.64 and 0.00 percent, respectively. The current study assessed three sprays of nine treatments against thrips that infested chilli under a field condition. All of the treatments were shown to be statistically effective in lowering the number of thrips on chilli when compared to an untreated control. The foliar spraying with isocycloseram 9.2% w/w DC (@ 0.0110%), broflanilide 300 g/l SC (@ 0.0037%), flubendiamide 19.92% + thiacloprid 19.92% w/w SC (@ 0.0159%) exhibited statistically similar results over an untreated control for lowering thrips on chilli. Similar results were documented by Hemalatha et al. (2025) [10] who observed isocycloseram 9.2% DC was most effective for cotton thrips. Blythe et al. (2022) [7] reported that isocycloseram was a novel isoxazoline insecticide very active against thysanopterans. Bekelja et al., in 2024 [5] reported that isocycloseram shows promising results against southern corn rootworm, Diabrotica undecimpunctata Howardi a peanut pest. Isocycloseram decreased thrips populations in blueberry plants in a greenhouse was documented by Shimat in 2024 [17] . These studies support our findings that isocycloseram 9.2% w/w DC is effective for thrips control on chilli. Chen et al. in 2022 [9] confirms that broflanilide was highly effective against various thrips species. Murali et al. in 2023 [13] , Prajapati and Patel (2025) [15] reported that thrips on chilli, gram pod borer on pigeonpea were effectively controlled by broflanilide. Bhede et al. (2008) [6] documented that newer insecticides cyantraniliprole and broflanilid effectively control thrips on chilli. Exciting results of broflanilide under laboratory condition against Thrips parvispinus were reported by Anu et al. (2024) [3] which are in support of our findings. Bojan et al. (2010) [8] reported that flubendiamide + thiacloprid 480 SC (ready mix) significantly lowered the whitefly population in okra. Cyantraniliprole displayed moderate toxicity against Thrips parvispinus (Karny) affecting at least two stages in either exposure route. (Ataide et al., 2024) [4] . Kaur et al. (2021) [11] demonstrated that thrips on cucumber was effectively controlled by flubendiamide 19.92% + thiacloprid 19.92% w/w SC which are in evidence to support our findings.
Effect of novel insecticides on yield of chilli 5. Effect of novel insecticides on yield of chilli (2023-24)
The treatment with flubendiamide 19.92% + thiacloprid 19.92% w/w SC (@ 0.0159%) found most effective in obtaining maximum yield of green chillies which noted 132.02 q ha -1 and it found on par to isocycloseram 9.2% w/w DC (@ 0.0110%) (125.34 q ha -1 ), broflanilide 300 g/l SC (@ 0.0037%) (121.63 q ha -1 ), fluxametamide 10% w/w EC (@ 0.0080%) (117.85 q ha -1 ) and cyantraniliprole 10.26% OD (@ 0.0123%) (115.18 q ha -1 ). An untreated control recorded minimum yield of 88.39 q ha -1 green chillies.
Effect of novel insecticides on yield of chilli (2024-25)
The treatment with flubendiamide 19.92% + thiacloprid 19.92% w/w SC (@ 0.0159%) found statistically most superior in obtaining maximum yield of green chillies which recorded 134.71 q ha -1 . Whereas, isocycloseram 9.2% w/w DC (@ 0.0110%) (130.08 q ha -1 ), broflanilide 300 g/l SC (@ 0.0037%) (124.66 q ha -1 ) and fluxametamide 10% w/w EC (@ 0.0080%) (124.23 q ha -1 ) were found statistically at par to flubendiamide 19.92% + thiacloprid 19.92% w/w SC (@ 0.0159%) over an untreated control (84.97 q ha -1 ).
Effect of novel insecticides on yield of chilli (Pooled)
It is revealed from pooled data that treatment flubendiamide 19.92% + thiacloprid 19.92% w/w SC (@ 0.0159%) was found most effective in obtaining maximum yield of green chillies which noted 133.37 q ha -1 and also found statistically on par to isocycloseram 9.2% w/w DC (@ 0.0110%) and broflanilide 300 g/l SC (@ 0.0037%) which recorded 127.71 and 123.14 as against 86.68 q green chillies ha -1 in an untreated control. In the current study flubendiamide 19.92% + thiacloprid 19.92% w/w SC (@ 0.0159%) found most effective as the combination of flubendiamide and thiacloprid is an effective tool against a broad spectrum of insect pests in chilli, including both chewing and sucking types. This treatment was followed by isocycloseram 9.2% w/w DC (@ 0.0110%) an isoxazoline insecticide that modulates GABA-gated chloride channels in the insect's central nervous system, effective against a wide range of crop-damaging pests, including lepidopterans, hemipterans, coleopterans, and thysanopterans (thrips). It was documented by Pradhan (2025) [14] who reported effectiveness of flubendiamide 19.92% + thiacloprid 19.92% w/w SC against fruit borers, whiteflies on chilli, cotton and isocycloseram against stem borers which contributed in the higher yield of green chillies which supports our findings. Broflanilide 300 g/l SC (@ 0.0037%) was the next best treatment in respect of good yield. The findings of Wale and Mohite (2019) [19] who reported effictiveness of broflanilide against diamond back moth as well as tobacco leaf eating caterpillar while findings of Shen et al. (2021) [16] who reported high level toxicity of broflanilide against two spotted spider mites supports our yield trends as in our investigation fruit borer and mites were the major pests which can threatens yield of green chillies.
