Inducible defences, chemical aposematism and the spatial ecology of plant–herbivore interactions in tall goldenrod, Solidago altissima L.

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants can respond to herbivore attack by inducing resistance traits that affect subsequent herbivore performance and behaviour. Here, we investigate how such induced responses in Solidago altissima L.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

Insect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

Integrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

Potential distribution of Spodoptera frugiperda (J.E. Smith) in China and the major factors influencing distribution

Global Ecology and Conservation, 2020
Fall armyworm, Spodoptera frugiperda (J.E. Smith) is one of the most important agricultural pests in the world. At the end of 2018, S. frugiperda was first found in Yunnan, China, and then it had spread rapidly to 19 provinces and posed a serious threat ...

Movement and Survival of Spodoptera litura (Lepidoptera: Noctuidae) Neonate Larvae on Cotton Expressing Bacillus thuringiensis Proteins

Entomologia Experimentalis et Applicata, EarlyView.
Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

Bioecologia e injúrias de Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) em milheto. [PDF]

, 2015
O presente trabalho teve por objetivo avaliar a suscetibilidade de quatro genótipos de milheto (Sauna B, BRS 1501, BRS 1502 e BRS 1503) ao ataque de uma das pragas de maior importância para a cultura, que é a lagarta-do-cartucho-do-milho, Spodoptera ...

Geographic Variation in Sexual Attraction of Spodoptera frugiperda Corn- and Rice-Strain Males to Pheromone Lures [PDF]

, 2014
The corn- and rice-strains of Spodoptera frugiperda exhibit several genetic and behavioral differences and appear to be undergoing ecological speciation in sympatry.

Leaf Extracts of Coffea racemosa Inhibit Trypsin Activity and Affect Larval Development in Spodoptera frugiperda and Diatraea saccharalis

Entomologia Experimentalis et Applicata, EarlyView.
Leaf extracts of Coffea racemosa inhibit digestive trypsins and impair the development of two major lepidopteran pests, Spodoptera frugiperda and Diatraea saccharalis. While both species showed significant enzymatic inhibition, biological responses differed markedly. D. saccharalis exhibited high mortality, whereas S.
