“…In plant health management, India has a total of 292 pesticides registered and per hectare consumption of pesticides in India is on rise (600 g/ha) after -10 (DPPQ, 2020. Injudicious use of pesticides has led to problems of resistance (Dhaliwal & Koul, 2010;Fand et al, 2019;Sethi & Dilawari, 2008;Thind et al, 2009), resurgence and residues. Not all crops have registered plant protection chemicals and farmers often use off label products that have implications on food safety and export.…”

Pandemics continue to affect the edifice of India’s biosecurity threatening food, nutrition, health, livelihood, biodiversity and ecosystem services. Rapid, largescale movement of people and material in a globalised world, climate change and inadequate surveillance will exacerbate pandemics in the years to come. Despite vaccines, synthetic drugs, agrochemicals playing a key role in mitigation, cascading problems of resistance, resurgence, food safety, biodiversity, and ecosystem services is a stark reality. For India to be a part of preparedness, transformational changes in transboundary pest surveillance, strict quarantine, rapid molecular diagnosis, anticipatory research, and training are essential. Transparency, political commitment, investment in research and development, analysis and interpretation of bigdata, meta-analysis, multi-lateral institutional/international cooperation is the way forward for preparedness and biosecurity. Pandemics need a united regional and global approach rather than mere national focus.

“…Several countries, namely, China (Wang et al, 2010 ), India (Kranthi et al, 2002 ), Iran (Basij et al, 2017 ), Israel (Alon et al, 2008 ), Malaysia (Shadmany et al, 2015 ), Pakistan (Ahmad et al, 2010 ), and the USA (Prabhaker et al, 2014 ), have reported the development of insecticide resistance in whitefly to even compounds of novel chemistry. Intensive and frequent use of insecticides, selection pressure, and choice of poor insecticides may be some of the other factors rendering resistance in whitefly both at field and laboratory levels (Sethi and Dilawari, 2008 ; Pietri and Liang, 2018 ). The neonicotinoid group of compounds, represented by imidacloprid, thiamethoxam, and others, are majorly used insecticides in controlling the whitefly population worldwide, including in India (Sethi and Dilawari, 2008 ; Yang et al, 2013 ; Pang et al, 2020 ).…”

Unraveling the Basis of Neonicotinoid Resistance in Whitefly Species Complex: Role of Endosymbiotic Bacteria and Insecticide Resistance Genes

Bemisia tabaci (whitefly) is one of the most detrimental agricultural insect pests and vectors of many plant viruses distributed worldwide. Knowledge of the distribution patterns and insecticide resistance of this cryptic species is crucial for its management. In this study, genetic variation of mitochondrial cytochrome oxidase subunit 1 (MtCoI) gene of B. tabaci was analyzed followed by a study of the infection profile of various endosymbionts in 26 whitefly populations collected from West Bengal, India. Phylogenetic analysis revealed Asia I as the major cryptic species (65.38%), followed by Asia II 5, China 3, and Asia II 7, which were diversified into 20 different haplotypes. In addition to the primary endosymbiont (C. poriera), each of the four whitefly species showed a variable population of three secondary endosymbionts, majorly Arsenophonus with the highest infection rate (73.07%), followed by Wolbachia and Rickettsia. Further phylogenetic analyses revealed the presence of two subgroups of Arsenophonus, viz., A1 and A2, and one each in Wolbachia (W1) and Rickettsia (R3). Resistance to thiamethoxam, imidacloprid, and acetamiprid insecticides was analyzed for a clear picture of pesticide resistance status. The highest susceptibility was noted toward thiamethoxam (LC50 = 5.36 mg/L), followed by imidacloprid and acetamiprid. The whitefly population from Purulia and Hooghly districts bearing Asia II 7 and Asia II 5 cryptic species, respectively, shows maximum resistance. The differences in mean relative titer of four symbiotic bacteria among field populations varied considerably; however, a significant positive linear correlation was observed between the resistance level and relative titer of Arsenophonus and Wolbachia in the case of imidacloprid and thiamethoxam, while only Wolbachia was found in case of acetamiprid. Expression analysis demonstrated differential upregulation of insecticide resistance genes with Purulia and Hooghly populations showing maximally upregulated P450 genes. Moreover, thiamethoxam and imidacloprid resistance ratio (RR) showed a significant correlation with CYP6CM1, CYP6DZ7, and CYP4C64 genes, while acetamiprid RR correlated with CYP6CX1, CYP6DW2, CYP6DZ7, and CYP4C64 genes. Taken together, these findings suggested that P450 mono-oxygenase and symbiotic bacteria together affected whitefly resistance to neonicotinoids. Hence, a symbiont-oriented management programme could be a better alternative to control or delay resistance development in whitefly and can be used for pesticide clean-up in an agricultural field.

Cotton is a major crop of Pakistan, and Bemisia tabaci (Homoptera: Aleyrodidae) is a major pest of cotton. Due to the unwise and indiscriminate use of insecticides, resistance develops more readily in the whitefly. The present study was conducted to evaluate the resistance development in the whitefly against the different insecticides that are still in use. For this purpose, the whitefly population was selected with five concentrations of each insecticide, for five generations. At G1, compared with the laboratory susceptible population, a very low level of resistance was observed against bifenthrin, cypermethrin, acetamiprid, imidacloprid, thiamethoxam, nitenpyram, chlorfenapyr, and buprofezin with a resistance ratio of 3-fold, 2-fold, 1-fold, 4-fold, 3-fold, 3-fold, 3-fold, and 3-fold, respectively. However, the selection for five generations increased the resistance to a very high level against buprofezin (127-fold), and to a high level against imidacloprid (86-fold) compared with the laboratory susceptible population. While, a moderate level of resistance was observed against cypermethrin (34-fold), thiamethoxam (34-fold), nitenpyram (30-fold), chlorfenapyr (29-fold), and acetamiprid (21-fold). On the other hand, the resistance was low against bifenthrin (18-fold) after selection for five generations. A very low level of resistance against the field population of B. tabaci, at G1, showed that these insecticides are still effective, and thus can be used under the field conditions for the management of B. tabaci. However, the proper rotation of insecticides among different groups can help to reduce the development of resistance against insecticides.
