Sexual selection, male morphology, and the efficacy of courtship signalling in two wolf spiders (Araneae: Lycosidae)
Abstract Males of the brush-legged wolf spider, Schizocosa ocreata (Araneae: Lycosidae), possess a conspicuous male secondary sexual character: dark pigmentation and tufts of bristles on the tibiaeExpand

Molecular phylogenetics and the evolution of host plant associations in the nematode genus Fergusobia (Tylenchida: Fergusobiinae).
Fergusobia nematodes (Tylenchida: Fergusobiinae) and Fergusonina flies (Diptera: Fergusoninidae) are putative mutualists that develop together in galls formed in meristematic tissues of many speciesExpand

DNA Barcoding Applied to Invasive Leafminers (Diptera: Agromyzidae) in the Philippines
Abstract DNA barcoding involves the sequencing of a single gene region from all species to provide a means for identifying all of life. Although appealing to many scientists, this idea has causedExpand

Repeated climate-linked host shifts have promoted diversification in a temperate clade of leaf-mining flies
A central but little-tested prediction of “escape and radiation” coevolution is that colonization of novel, chemically defended host plant clades accelerates insect herbivore diversification. ThatExpand

Hidden Neotropical Diversity: Greater Than the Sum of Its Parts
The diversity of tropical herbivorous insects has been explained as a direct function of plant species diversity. Testing that explanation, we reared 2857 flies from flowers and seeds of 24 speciesExpand

Phylogenetic relationships within the leaf-mining flies (Diptera: Agromyzidae) inferred from sequence data from multiple genes.
The leaf-mining flies (Diptera: Agromyzidae) are a diverse group whose larvae feed internally in leaves, stems, flowers, seeds, and roots of a wide variety of plant hosts. The systematics ofExpand

Mitochondrial Phylogeography of Vegetable Pest Liriomyza sativae (Diptera: Agromyzidae): Divergent Clades and Invasive Populations
Abstract The leafmining fly Liriomyza sativae Blanchard is an important polyphagous pest of vegetables crops in the United States and around the world. Phylogeographic analysis of mitochondrialExpand

Tracing the geographical origin of Megastigmus transvaalensis (Hymenoptera: Torymidae): an African wasp feeding on a South American plant in North America
Determining the geographical origin of an introduced organism can be critical to understanding or managing a non‐native species, but is often difficult when the organism is small or inconspicuous. WeExpand

The nematode genus Fergusobia (Nematoda: Neotylenchidae): molecular phylogeny, descriptions of clades and associated galls, host plants and Fergusonina fly larvae
Collection data and biological information is presented on the genus Fergusobia (Nematoda: Neotylenchidae) from Australasia, India and The Philippines, an emended diagnosis of the genus is presented,Expand
