Tuta absoluta
Serious tomato leafminer causing blotch mines and fruit damage.
Tuta absoluta is a highly damaging moth pest of tomato. Larvae mine leaves, stems and fruit, causing blotch mines, necrotic patches and entry holes in fruit. Populations build quickly in warm glasshouses. Biological control relies on egg parasitoids such as Trichogramma achaeae, and mirid predators including Macrolophus pygmaeus and Nesidiocoris tenuis. Traps, exclusion netting and strict sanitation are essential parts of the IPM programme.
