“…One application of emamectin benzoate/chlorfenapyr along with some plant products was found to be much better in suppression of leaf curling intensity in chilli (Chakraborti et al 2015). Effectiveness of emamectin benzoate in the present study was also supported by study conducted by Ravikumar et al (2016), where they reported that emamectin benzoate 5 sg @0.4 g per litre of water was very effective against chilli thrips, S. dorsalis. A study conducted on efficacy of biorational insecticides against chilli thrips, S. dorsalis by Aristizábal et al (2017) was also consistent with present study where consistent use of spinosad was the most effective treatment against chilli thrips.…”

Considering the economic significance of S. dorsalis in chilli crop, a study was carried out at the ICAR-Research Complex for Eastern Region, Farming System Research Centre for Hill and Plateau Region, Ranchi, Jharkhand during the spring season of 2019 and 2020 to find out the effective chemical molecules for managing this pest. Effectiveness of 8 modern insecticides against S. dorsalis and their effect on coccinellid predators was evaluated. Efficacy of insecticides was determined by comparing number of thrips, immature stages and adults of natural enemies, marketable yield in insecticide treated versus untreated control plots. Application of spinosad @70 g a.i./ha, Emamectin benzoate 5 sg @11 g a.i./ha, Imidacloprid 200 sl @40 g a.i./ha and Fipronil 5 sc @30 g a.i./ha were found to be effective against S. dorsalis in chilli. Other insecticides were inconsistent in effectiveness against S. dorsalis population. Fenpropathrin followed by Imidacloprid were found to cause maximum reduction and Spinosad and Emamectin benzoate caused lowest reduction of coccinellid population. Thus, based on the present study, Spinosad, Emamectin benzoate, Fipronil and Imidacloprid are recommended to manage S. dorsalis on rotational basis in chilli ecosystem.

“…Imidacloprid is activity on various sucking pests, containing thrips and wide variety insecticide known for pest (McKenzie et al, 2015). A study worked on effectiveness of biorational insecticides on chilli thrips and S. dorsalis (Ravikumar et al, 2016), where they reported that, emamectin benzoate 5 sg @0.4 g per liter was very successful against chilli thrips and S. dorsalis.…”

The common onion Allium cepa L., belonging to family Alliaceae is considered as one of the oldest cultivated plants worldwide and cultivated under a widely range of climates. Onion has a great economic importance and used in the nutrition habits in all households. There are several insect pests linked with cultivated onion in the filed such as onion thrips. Onion thrips (Thrips tabaci) are important pests on onion and the populations can develop very rapidly so it is necessary to control its population on onion. The experiments were applied in the field to evaluate four synthetic pesticides (imidacloprid, acetamiprid, thiamethoxam and lambda-cyhalothrin) and insecticide "abamectin" and their mixtures, also to study combination of these compounds with Nonylphenol Ethoxylate (NP9) as adjuvants on their toxicity against Thrips tabaci on the onion field during 2023 season. The obtained results showed that, all tested compounds when used alone or in their mixtures or combination with (NP9) as adjuvants were highly effective in controlling Thrips tabaci.

“…Sumitha et al (2008) investigated that population of Scirtothrips dorsalis was controlled effectively by fipronil 5 SC @ 0.01%. Ravikumar et al (2016) observed that maximum yield (30050 kg ha -1 ) was recorded by spray of Spinosad 45 SC @ 0.01 % against thrips.…”
