Abstract Invasive alien species (IAS) exert a negative impact on biodiversity by competing with native for the same trophic resources. Drosophilids are good models studying biological invasions. Brazil has 14 IAS drosophilids, four invasions in last 30 years. These cause damage to fruit crops and ecosystems. The relationship between especially immature stages, environment is an under‐explored field. Such studies important assess adaptive success of impacts species. Here we investigate use fruits as larval development sites neotropical drosophilids 12 plant collected from Atlantic Forest Caatinga biomes. Approximately 8 kg were investigated, which 5681 emerged (nine eight IAS). accounted more than 90% abundance hatchings occupied types compared drosophilids. Zaprionus indianus , Drosophila malerkotliana D. nasuta stood out among invasive species, latter invaded only decade ago high potential, surpassing number resources used. Neotropical used less greater interactions occurred plants discussed terms evolutionary mechanisms. We found niche overlap within group well this result competitive advantages

Propagule production of regional entomopathogenic fungi against Drosophila suzukii , an emerging fruit pest in southern Chile

Journal of Berry Research, Journal Year: 2025, Volume and Issue: unknown

Published: April 4, 2025

Background: Berry crops in Southern Chile with a temperate humid climate are threatened by emerging invasive Drosophila suzukii , and there is urgent need to provide efficient tools for integrated control of this pest. Objective: This study aims compare the potential selected entomopathogenic Beauveria bassiana Metarhizium spp. strains produce fungal propagules new conidia on microsclerotia. Materials: Strains isolated from soil samples collected affected berry plantations highly virulent against D. were tested standard culture conditions, conidial production microsclerotia determined at 15°C 25°C. Results: The capacities conidia, blastospores depended strains. lower temperature did not affect Conclusions: There promising candidates immediate development specific mycoinsecticide most appropriate propagule; ability high numbers encourages search innovative formulations Chile.
