The outbreak is in a glasshouse at a nursery site in the South of England in a growing and finished crop of Begonia, produced from cuttings imported from the Netherlands. Sixteen Spodoptera spp. larvae have been detected, two of these have been confirmed as S. litura when they emerged as adults in quarantine. No adults have been found in the nursery to date and therefore there is no evidence of a second generation. The nursery concerned is conducting regular checks for further larvae and monitoring for adults using light traps. Eradication is being pursued using a combination of insecticidal treatments and hand removal of larvae.
