Pest Management Science, Journal Year: 2025, Volume and Issue: unknown

Published: April 29, 2025

Abstract BACKGROUND The black bean bug Brachyplatys subaeneus is a crucial legume crop pest native to Asia. It has been introduced the Americas and rapidly in tropical subtropical regions, where it poses serious threat local crops. However, population structure invasive sources of this have never studied, hindering effective monitoring management. Here, we investigated genetic populations based on nuclear SNP data relationship between Panama samples COI 16S rRNA sequences. In addition, constructed ecological niche models predict its potential invasion areas. RESULTS We found that B. comprised three geographic lineages (NO, PH SO) within range, with strong differentiation these lineages. Genetic relationships mitochondrial DNA indicated used study were derived from NO lineage. Ecological modelling shows wide range suitable habitats northern central regions South America, suggesting expand further south America. CONCLUSION This revealed inferred possible geographical origin populations, areas for bug. Our findings could provide new insights into management efforts pest. © 2025 Society Chemical Industry.

Invasive alien plants (IAPs) present a severe threat to native ecosystems and biodiversity. Comprehending the potential distribution patterns of these plant invaders their responses climate change is essential. Parthenium hysterophorus , Americas, has become an aggressively invasive species since its introduction China in 1930s. This study aims collect reconstruct historical occurrence invasion P. . Using optimal MaxEnt model, geographical distributions were predicted based on screened occurrences environmental variables under current three future scenarios 2030s, 2050s, 2070s (i.e., SSP1-2.6, SSP2-4.5, SSP5-8.5), risk Chinese cities, croplands, forests, grasslands was assessed. The results show that: (1) initially invaded highly suitable areas further spread regions with non-analogous conditions. (2) Under climatic conditions, overall characterized by more southeast less northwest. Climate variables, including mean annual temperature (bio1), precipitation wettest month (bio13), isothermality (bio3), seasonality (bio4), are primary factors influencing distribution.

Abstract The increased incidence of invasive species introductions is a hallmark global change, but their associated environmental and economic impacts are vastly underestimated. Assessing managing the impact requires understanding weather driven dynamics as basis for predicting potential geographic distribution relative abundance.
