The emerging importance of noncoding RNAs in the insecticide tolerance, with special emphasis on Plutella xylostella (Lepidoptera: Plutellidae)

Abstract

Recently generated high-throughput sequencing data sets have shed light on the important regulatory roles of noncoding RNA (ncRNA) molecules in the development of higher organisms. Nowadays it is well-known that regulatory ncRNAs can bind complementary RNA or DNA sequences and recruit chromatin remodelers to selectively modulate gene expression. Consequently, genome sequencing and transcriptomics technologies are now being used to reveal hidden associations among ncRNAs and distinct biological mechanisms. This is the case for the diamondback moth Plutella xylostella, a worldwide pest known to infest cruciferous crops and to display resistance to most insecticides, including Bacillus thuringiensis (Bt) based biopesticides. In P. xylostella, it is thought that ncRNAs could play important roles in both development and insecticide resistance. This review will highlight recent insights into the roles of ncRNAs in P. xylostella and related lepidopterans, and will outline genetic engineering technologies which might be used to design efficient ncRNA-based pest control strategies.

Volatile DMNT directly protects plants against Plutella xylostella by disrupting the peritrophic matrix barrier in insect midgut

“…Mitigating the detrimental effects of insect pests constitutes a long-term goal for researchers, breeders, and farmers ( Johnson and Züst, 2018 ; Tay and Gordon, 2019 ). The diamondback moth Plutella xylostella (Lepidoptera: Plutellidae ) has been ranked as one of the most difficult pests to control due to its short life cycle, high migration rate, strong tolerance to environmental stresses, and rising resistance to available insecticides ( Shakeel et al, 2017 ; Vaschetto and Beccacece, 2019 ). An estimated 4–5 billion dollars are devoted each year to control of this pest worldwide ( Zalucki et al, 2012 ).…”

Profiling of MicroRNAs in Midguts of Plutella xylostella Provides Novel Insights Into the Bacillus thuringiensis Resistance

“…One of the main challenges of DBM control is its rapid evolution of resistance against a wide range of insecticides, including Bt-based products ( Furlong et al, 2013 ). Considering its severe insecticide-resistance, short life cycle and host range expansion ( Li et al, 2016 ), microRNA (miRNA)-mediated efficient and environmentally friendly approaches have been proposed to combat DBM ( Vaschetto and Beccacece, 2019 ).…”

The determination of Plutella xylostella (L.) GSTs (PxGSTs) involved in the detoxification metabolism of Tolfenpyrad

“…The TFP was diluted using 50% acetone-water mixture to eight concentrations (1,2,4,8,16,32,64 and 128 mg L -1 ). The control group was treated with a 50% acetone-water mixture.…”

“…The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) is one of the most destructive pests of cruciferous plants in the world. 1,2 The annual cost of controlling P. xylostella has reached billions of dollars. [3][4][5][6] Presently, chemical control is the most effective measure to prevent P. xylostella.…”
