Abstract: We tested several methods for assessing the mating status of male obliquebanded leafrollers, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae). In four experiments, we established that the technique developed to determine mating status of male spruce budworms, Choristoneura...

Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...

Relationships and introgression within Carthamus (Asteraceae), with an emphasis on safflower (Carthamus tinctorius).
DownloadFall 2010
Carthamus (Asteraceae) contains both crop species (C. tinctorius, safflower) and weedy species, increasing the need for a better understanding of the genus. Despite previous studies, many outstanding questions remain regarding the phylogenetic relationships of safflower, especially with regards...

Species delimitation in the Choristoneura fumiferana species complex (Lepidoptera: Tortricidae)
DownloadFall 2010
Species identifications have been historically difficult in the economically important spruce budworm (Choristoneura fumiferana) pest complex. Morphological, ecological, behavioural, and genetic characters have been studied to try to understand the taxonomy of this group, but diagnostic character...

Temporal isolation contributes to ecological speciation in a diversity of insect taxa. Such prezygotic isolation can reduce or stop hybridization between closely related taxa or populations, leading to speciation. Within the spruce budworm (Choristoneura fumiferana) species complex, hybridization...
