Introduction A species is described as an invader when it colonizes and persists
in an ecosystem in which it has never been before (Mooney and Drake, 1989).
Invasions by insects seem to be rather well documented, but that is a false
impression. It is only for two categories of insect species that documentation of
successful invasions is complete: (i) for pest species (usually herbivores); and (ii)
for natural enemies (predators and parasitoids of insect pests, or phytophagous
insects ...

The major acorn insects can be divided into primary and secondary invaders.
Primary invaders directly enter the acorn whereas secondary invaders require a
crack or other opening in the acorn for entry (Murtfeldt, 1894; Winston, 1956;
Kearby et al., 1986). The most important primary insect invaders are the Curculio
acorn weevils, the filbertworm moth and the cynipid gall wasps. Some species of
fungi also are primary invaders. Although there are numerous secondary insect
invaders ...

One interesting pattern in insect faunal changes is the disparity in the movement
of species: North America has received many more insect invaders from Europe
than the reverse. Counting the number of phytophagous tree-feeding species that
invaded from Europe to North America, about 300 species were documented (
Niemela ̈ and Mattson 1996, Mattson et al. 2007), whereas only 57 species
have reached Europe from North America, about a fivefold difference (Table 15.1
