Observed spread & simulated build-up

Replay verified EPPO first reports year by year. Each country lights up when it is first reported; dots are sized by tomato-export volume as a proxy for likely problem size, and faint trails trace likely introduction paths.

How to read it Dot size & colour intensity = tomato-export volume (problem-size proxy) Soft fade-out = uncertainty (illustrative, not measured) Soft trail = likely introduction path

Dots are placed at EPPO-reported countries; size, colour and trails are illustrative, not measured. The map does not show the full native South American pest range.

Where it is established today

A snapshot from the EPPO distribution table. Country totals come from the distribution records; the report entries in the feed below are timeline events and need not map one-to-one to countries.

By the numbers

Presence by EPPO region

EPPO groups present countries into continental regions. Counts are unique countries with a present status.

How the invasion unfolded

Each milestone is drawn from EPPO Reporting Service articles; wording is kept cautious and source-linked.
