Aspect of the biology of sod webworms (Lepidoptera: Pyralidae: Crambinae) and turfgrass inhabiting insects of Virginia
Turfgrass is subject to attack by a variety of insect pests. However, there has been no research on the sod webworm pests associated with turfgrass in Virginia and little research on habitat preferences of other insect pests of turf. The purpose of this research was to contribute to the basic …

Taxonomic, biological, population dynamics and behavioural studies on sod webworms (Lepidoptera : pyralidae: crambinae and scopariinae) of some Waikato (New Zealand) hill country pastures
New Zealand has a rich fauna of sod webworms (Lepidoptera: Pyralidae: Crambinae and Scopariinae) which have been implicated in sporadic outbreaks of pasture damage. This study investigates sod webworms of south facing hill country slopes of some Waikato pastures. Four aspects are considered: …

Patterns of association in a co-introduced insect herbivore and parasitoid wasp
… date is unclear. Copidosoma sosares attacks webworms on both wild parsnip and cow parsnip, but its distribution is patchy compared to parsnip webworms; with rare exception, C. sosares populations are restricted to the western U.S. In Chapter 2, I used a mitochondrial molecular marker to …

Consequences of global redistribution on the ecology and evolution of the invasive weed Pastinaca sativa and its associated insect fauna
… webworm herbivory for 140 years until 2004, when webworms were discovered, presumably having been accidentally introduced. This escape and subsequent reassociation of wild parsnips with parsnip webworms in NZ presented a unique opportunity to study herbivore-mediated evolution as it occurs. In …

Competition and Community Interactions of Two Generalist Herbivores
… (<em>Malacosoma californicum</em>) and fall webworms (<em>Hyphantria cunea</em>) on their shared host plant, chokecherries (<em>Prunus virginiana)</em>. Within species, I found that time-lagged intraspecific competition reduced larval fitness, that plants that had been fed upon by tent …
