Multi-generational adaptation to Solanum nigrum increases reproduction and decreases microbial diversity of Aphis gossypii

Aphis gossypii Glover (Hemiptera: Aphididae) causes considerable damage to crop yields globally. Solanum nigrum (Solanales: Solanaceae), an annual malignant weed, serves as a crucial weed host for A. . However, the potential mechanisms by which adapts different hosts during transition between crops, such Gossypium hirsutum (Malvales: Malvaceae) and S. remain elusive. We calculated life table parameters of after rearing on ten generations. The fifth generation (T5) exhibited strongest adaptability , demonstrating notably higher values r (intrinsic rate increase), λ (finite fecundity compared first (T1). Upon retransferring T1, T5, tenth (T10) were retransferred G. (designated T1-M, T5-M, T10-M, respectively), T5-M showed superior both T1-M T10-M. 16S rRNA sequencing qPCR analyses indicated significant decrease in diversity symbiotic bacterial community T5 T10. Notably, Buchnera Arsenophonus two dominant bacteria related metabolism relative abundance T10 significantly increased M T, while decreased markedly. KEGG (Kyoto Encyclopedia Genes Genomes) function prediction analysis suggested that roles are primarily linked metabolic processes. Therefore, adaptation enhances its population expansion potentially involving functions These findings provide theoretical foundation scientific management fields.

Comparison of gut transcriptome and bacterial composition of the yellow peach moth, Conogethes punctiferalis larvae associated with host plants adaptation

CABI Agriculture and Bioscience, Journal Year: 2024, Volume and Issue: 5(1)

Published: June 23, 2024

Abstract The yellow peach moth, Conogethes punctiferalis , is one of the most destructive polyphagous pests to corn crops in Huang-Huai-Hai summer region China. However, little known about host plant adaptation mechanism C . In this study, we analyzed performance C. on two its favorable plants (corn and sorghum). Then, used RNA-seq 16S rRNA sequencing explore potential these plants. Results showed that gained more fresh weight sorghum while total lipid triglyceride content was significantly lower than corn. total, 2155 genes weredifferentially expressed (DEGs) between reared Most DEGs were involved nutritional biosynthesis metabolism including amino acid biosynthesis, protein digestion absorption, glycolysis. Enzymatic analyses revealed had higher trypsin activity but P450 sorghum. Meanwhile, harbored gut bacteria, diversity functional prediction bacteria functions differently enriched Taken together, findings clarify impact gene expression They also suggest plasticity cooperatively contribute insect insects.

Transcriptomic and Metatranscriptomic Analyzes Provide New Insights into the Response of the Pea Aphid <em>Acyrthosiphon pisum</em> (Hemiptera: Aphididae) to Acetamiprid

Published: March 22, 2024

Acetamiprid is a broad-spectrum neonicotinoid insecticide used in agriculture to control aphids. While recent studies have documented resistance acetamiprid several aphid species, the underlying mechanisms are still not fully understood. In this study, we analyzed transcriptome and metatranscriptome of laboratory strain pea aphid, Acyrthosiphon pisum (Harris, 1776), with reduced susceptibility after nine generations exposure identify candidate genes microbiome involved adaptation process. Sequencing both selected (RS) non-selected (SS) strains allowed identification 14858 4938 new transcripts. Most differentially expressed were associated catalytic activities metabolic pathways involving carbon fatty acids. Specifically, alcohol-forming acyl-CoA reductase (FAR) synthetase (ACSF2), synthesis epidermal wax layer components, significantly upregulated RS, suggesting that involves thicker protective layer. Metatranscriptomic analysis revealed subtle shifts RS. These results contribute deeper understanding by provide insights for strategies.
