Life Table Parameters of the Tomato Leaf Miner Tuta absoluta (Lepidoptera: Gelechiidae) on Five Tomato Cultivars in China

Insects, Journal Year: 2024, Volume and Issue: 15(3), P. 208 - 208

Published: March 20, 2024

Tomato is the most preferred host plant for Tuta absoluta, a newly emerged devastating invasive pest in China. However, no study has evaluated damage risk of T. absoluta on processed tomato worldwide. In current study, life table parameters were systematically investigated five cultivars (one fresh cultivar, four cultivars) to determine their susceptibility infestation. had better population growth ability tomato, “Dafen”, showing shorter duration preadult stage, higher lifetime fecundity, and intrinsic rate increase compared cultivars. Meanwhile, among different also showed significant differences. Th9 was susceptible attack, while Th1902, Heinz1015, Dimen2272 least suitable ones its development reproduction. summary, these are recommended commercial production reduce caused by improve integrated management strategy.

Development of an on‐site diagnostic LAMP assay for rapid differentiation of the invasive pest Phthorimaea absoluta (Meyrick) using insect tissues

Pest Management Science, Journal Year: 2024, Volume and Issue: 80(8), P. 4069 - 4073

Published: April 2, 2024

Abstract BACKGROUND The tomato leafminer, Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a destructive invasive pest that originated in South America and has spread within China since 2017. A rapid method for on‐site identification of P. urgently needed interception this across China. RESULTS We developed loop‐mediated isothermal amplification (LAMP) technique to differentiate from Liriomyza sativae , Chromatomyia horticola operculella using extracted genomic DNA, which was then refined create an LAMP diagnostic can be performed under field conditions without the need laboratory equipment. CONCLUSION In present research, we differentiation other insects with similar morphology or damage characteristics © 2024 Society Chemical Industry.

Electroantennogram and machine learning reveal a volatile blend mediating avoidance behavior by Tuta absoluta females to a wild tomato plant

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Abstract Tomato cultivation is threatened by the infestation of nocturnal invasive tomato pinworm, Tuta absoluta . This study was based on field observations that a wild plant, Solanum lycopersicum var. cerasiforme , grown in Mount Kenya region, Kenya, less attacked T. absoluta, unlike cultivated plants like S. (var. Rambo F1). We hypothesized plant may be actively avoided gravid females because emission repellent allelochemical constituents. Therefore, we compared levels pest monocrops and intercrops two genotypes, characterized headspace volatiles, then determined compounds detectable insect through gas chromatography-linked electroantennography (GC-EAG), finally performed bioassays using blend four EAG-active unique to tomato. found significant reductions monocrop tomato, plant. Quantitative qualitative differences were noted between volatiles plants, day night volatile collections. The most discriminating treatments varied with variable selection or machine learning methods used. In GC-EAG recordings, 16 including hexanal, ( Z )-3-hexenol, α -pinene, β -myrcene, -phellandrene, E )- -ocimene, terpinolene, limonene oxide, camphor, citronellal, methyl salicylate, -caryophyllene, others tentatively identified as 3,7,7-Trimethyl-1,3,5-cycloheptatriene, germacrene D cis -carvenone oxide detected antennae females. Among these compounds, -caryophyllene -phellandrene are top 5 highlighted methods. A citronellal only showed dose-dependent repellence wind tunnel. provides some groundwork for exploiting allelochemicals development novel integrated management approaches against

Microorganisms in the guts of insects enhance adaptability their hosts with different lifestyles, or those that live habitats. Tuta absoluta is an invasive pest a serious threat to tomato production China. It has quickly spread and colonized Xinjiang, Yunnan other provinces regions. We used Illumina HiSeq next generation sequencing 16S rRNA gene study analyze composition diversity gut microbiota three geographical populations T. absoluta. At phylum level, most common bacteria across all were Proteobacteria Firmicutes. An uncultured bacterium Enterobacteriaceae was dominant bacterial genus microbiotas. There no significant differences alpha metrics among Spanish, Xinjiang populations. The structures similar based on PCoA NMDS results. results confirmed microbial from regions similar.

Combined PacBio Iso-Seq and Illumina RNA-Seq Analysis of the Tuta absoluta (Meyrick) Transcriptome and Cytochrome P450 Genes

Insects, Journal Year: 2023, Volume and Issue: 14(4), P. 363 - 363

Tuta absoluta (Meyrick) is a devastating invasive pest worldwide. The abamectin and chlorantraniliprole complex have become an alternative option for chemical control because they can enhance insecticidal activity delay increased drug resistance. Notably, pests are inevitably resistant to various types of insecticides, compound insecticides no exception. To identify potential genes involved in the detoxification T. absoluta, PacBio SMRT-seq transcriptome sequencing Illumina RNA-seq analysis complex-treated were performed. We obtained 80,492 non-redundant transcripts, 62,762 (77.97%) transcripts that successfully annotated, 15,524 differentially expressed (DETs). GO annotation results showed most these DETs biological processes life-sustaining activities, such as cellular, metabolic, single-organism processes. KEGG pathway enrichment pathways related glutathione metabolism, fatty acid amino synthesis, metabolism response absoluta. Among these, 21 P450s (11 upregulated 10 downregulated). qRT-PCR eight P450 after treatment consistent with RNA-Seq data. Our findings provide new full-length transcriptional data information further studies on detoxification-related
