Abstract The spotted-wing Drosophila, Drosophila suzukii (Matsumura, 1931)(Diptera:
Drosophilidae), is an invasive pest which causes important damage to fruit crops. Despite …

We tested the hypothesis that forest and prairie populations of the gall‐inducing fly, Eurosta
solidaginis, have diverged in response to variation in selection by its host plant Solidago …

Helicoverpa armigera (Hübner), the major target pest of transgenic Bacillus thuringiensis
(Bt) cotton, remains susceptible to Bt cotton in China at present. Behavioural avoidance by …

Host specialization plays a key role in the extreme diversification of phytophagous insects.
Whereas proximate mechanisms of specialization have been studied extensively, their …

The green peach aphid, Myzus persicae (Sulzer), is a generalist insect herbivore capable of
using a wide range of cultivated plants and weeds. In this laboratory study, we examined the …

Native insects can form novel associations with introduced invasive plants and use them as
a food source. The recent introduction into eastern North America of a nonnative European …

This study investigated host-specificity and phylogenetic relationships in Australian galling
flies, Fergusonina Malloch (Diptera: Fergusoninidae), in order to assess diversity and …

Native insects have the capacity to form novel associations with invasive plants, which in
some cases may allow them to exploit the invaders as hosts. To date, little work has been …

Leafminers face many threats in their life, ranging from plant defenses to parasitism. Plants
have evolved some unique defenses against leafminers, both direct and indirect defenses …

Herbivorous insects are characterized by a great diversity of host-plant associations, yet the
processes driving host range evolution are not fully understood. In my dissertation, I …
