First record and integrative analysis of the invasive aphid Cinara pilicornis in South Korea.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study presents the first record of the spruce shoot aphid, Cinara pilicornis (Hartig, 1841) (Hemiptera: Aphididae: Lachninae), in South Korea. Native to Europe, C. pilicornis has expanded its distribution globally and is recognized as a significant quarantine pest in South Korea, posing substantial ecological and economic risks to native spruce trees and forestry ecosystems. Through detailed morphological and molecular analyses, including scanning electron microscopy (SEM) and mitochondrial COI gene sequencing, the identity of C. pilicornis was confirmed. Phylogenetic analyses (BI and NJ) and species delimitation methods (ABGD, ASAP, and bPTP) further validated the species classification, with all South Korean populations belonging to haplotype 1 a putative ancestral haplotype widely distributed across other regions. Population analyses revealed limited genetic diversity in South Korea, suggesting a recent introduction. Climatic niche modeling indicated that C. pilicornis has the potential to establish populations in temperate and subtropical regions, including Europe, North America, coastal South America, and East Asia. Observations of colony behavior on Picea abies revealed high honeydew production and the formation of black sooty mold, causing visible damage to host plants. This study underscores the importance of strengthening quarantine measures and monitoring native spruce trees in national parks to mitigate the spread and impact of this invasive pest. Effective management strategies are essential to prevent further ecological disruption and economic losses caused by C. pilicornis.
