“…To cope with xenobiotic compounds, the insects can utilize a variety of detoxifying enzymes, including glutathione S-transferase (GST) and carboxylesterase (CarE) [15–18]. Or, the insects can decrease the sensitivity of the target site of pesticides, for example, the nerve conduction enzyme acetylcholinesterase (AChE) [16].…”

BackgroundThe cereal weevil, Sitophilus zeamais is one of the most destructive pests of stored cereals worldwide. Frequent use of fumigants for managing stored-product insects has led to the development of resistance in insects. Essential oils from aromatic plants including the tea oil plant, Melaleuca alternifolia may provide environmentally friendly alternatives to currently used pest control agents. However, little is known about molecular events involved in stored-product insects in response to plant essential oil fumigation.ResultsM. alternifolia essential oil was shown to possess the fumigant toxicity against S. zeamais. The constituent, terpinen-4-ol was the most effective compound for fumigant toxicity. M. alternifolia essential oil significantly inhibited the activity of three enzymes in S. zeamais, including two detoxifying enzymes, glutathione S-transferase (GST), and carboxylesterase (CarE), as well as a nerve conduction enzyme, acetylcholinesterase (AChE). Comparative transcriptome analysis of S. zeamais through RNA-Seq identified a total of 3,562 differentially expressed genes (DEGs), of which 2,836 and 726 were up-regulated and down-regulated in response to M. alternifolia essential oil fumigation, respectively. Based on gene ontology (GO) analysis, the majority of DEGs were involved in insecticide detoxification and mitochondrial function. Furthermore, an abundance of DEGs mapped into the metabolism pathway in the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database were associated with respiration and metabolism of xenobiotics, including cytochrome P450s, CarEs, GSTs, and ATP-binding cassette transporters (ABC transporters). Some DEGs mapped into the proteasome and phagosome pathway were found to be significantly enriched. These results led us to propose a model of insecticide action that M. alternifolia essential oil likely directly affects the hydrogen carrier to block the electron flow and interfere energy synthesis in mitochondrial respiratory chain.ConclusionThis is the first study to perform a comparative transcriptome analysis of S. zeamais in response to M. alternifolia essential oil fumigation. Our results provide new insights into the insecticidal mechanism of M. alternifolia essential oil fumigation against S. zeamais and eventually contribute to the management of this important agricultural pest.

“…These two enzymes generally have key functions in the interaction between insects and fumigants. Earlier workers 23,26 found that natural fumigants caused a significant inhibition of these two enzymes. Hence, in the present study exposure of essential oil vapours might be causes inhibition of enzymes acetylcholinesterase and glutathione S-transferase present in the insects resulted the death of insects.…”

“…The present findings are supported by Conti et al 22 and indicate that insecticidal mode of action of the studied essential oil largely attributed to their fumigant action and found to be toxic by penetrating the insect body via respiratory system. Plant products inter into the tissue and organ of target insects and affect the activity of various detoxifying enzymes 23 . Francis et al 24 investigated the insecticidal mechanisms by determining the activity of detoxifyning enzymes after biological insecticides have entered the target insects.…”

“…In a previous screening program for new agrochemicals from Chinese medicinal herbs, I. verum powder has been shown to possess insecticidal activity against S. zeamais and Cryptolestes pusillus Schönherr (Li et al 2013). Other studies have indicated that the essential oil of I. verum has repellent and fumigant actions on S. Zeamais, Blattella germanica (Chang and Ahn 2002), Lasioderma serricorne, Sitophilus oryzae, Callosobruchus chinensis (Kim et al 2003a, b), and Aedes aegypti (Dana and Wej 2006).…”
