Invasive leafminers on woody plants: a global review of pathways, impact, and management
(2018)
for insects (Liebhold et al. 2012).
Among invasive herbivore insects, leafminers represent
an important group. Many leafminers are known as impor-
tant economic pests of agricultural crops, whereas others
threaten forest and urban plants (Spencer 1973...
