The tomato leaf miner, Tuta absoluta, is a devastating pest of tomato. Originating from Latin America, T. absoluta has spread via infested fruits and packaging material to Europe, North Africa and the Middle East.

Its primary host is tomato, but it also affects potato, aubergine, beans and others.  Continue reading

The life and travels of Tuta absoluta, the tomato leaf miner

The pesky tomato pest, Tuta absoluta, has decided in recent years that it wants to see a little more of the world. This moth is native to Peru and is probably widespread in all countries in South America, but in the last 5 years the pest has also been found in the Mediterranean, spreading at a rapid pace. T. absoluta seems to have found the Mediterranean a perfect new home where it can breed 10-12 generations per year and each female can lay 250-300 eggs in its lifetime. The pest is crossing boarders and devastating tomato production in both protected and open fields. Just in 2010 the Reporting Service from the European and Mediterranean Plant Protection Organisation (EPPO) reported first records in Bulgaria, Cyprus, Germany, Israel, Hungary, Kosovo, Guernsey and Turkey and in 2011 in Greece, Lithuania and Iraq. The Tuta absoluta information network also reports the pest in Bahrain, Jordan, Kuwait, Lebanon, Saudi Arabia, Syria, Sudan and most recently in glasshouses in Russia, although these reports have not been confirmed officially by NPPOs.
