New Insights into the Colonization and Release Processes of Xenorhabdus nematophila and the Morphology and Ultrastructure of the Bacterial Receptacle of Its Nematode Host, Steinernema carpocapsae
TLDR
It is suggested that bacterial motility is not required for movement out of the distal region of the receptacle and that hemolymph-induced esophageal pumping provides a force for the release of X. nematophila out of a receptacles and into the intestinal lumen. Expand
Molecular systematics of the tephritoidea (Insecta: Diptera): Phylogenetic signal in 16S and 28S rDNAs for inferring relationships among families
TLDR
While 16S rDNA is useful for resolving more recent phylogenetic divergences, 28S r DNA can be used to define much deeper phylogenetic branches and the combined analysis of the 16S and28S rDNAs enhances the overall resolution without losing phylogenetic signal from either single gene analysis.

In Vitro Screening of Antibacterial Agents for Suppression of Fire Blight Disease in Korea
TLDR
In planta test based on disease severity including ooze and water-soaked formation on immature pears, bacterial populations on blooms, and blight lesion formation in artificially inoculated shoots, kasugamycin, oxytetracycline and streptomycin have been shown the most efficiency among tested antibiotics. Expand
Evaluation of Insecticidal Efficacy of Plant Extracts Against Major Insect Pests
Insecticidal efficacies of plant extracts and environmental friendly agro-materials against green peach aphids, two spotted spider mites, and diamondback moths were evaluated in the lab condition.Expand
New species of Simulium (Nevermannia) from Korea, with reference to its allied species in the S. vernum species group (Diptera: Simuliidae) in Korea and Japan
The larvae and pupae of a new species, Simulium (Nevermannia) immaculatum sp. nov., are described from Korea. Descriptions are supplemented with photographs of larvae and pupae and habitatExpand
Morphology and ultrastructure of the bacterial receptacle in Steinernema nematodes (Nematoda: Steinernematidae).
TLDR
The observations confirmed the bacterial receptacle is a modification of the two most anterior cells of the ventricular portion of the intestine, and all examined taxa members of the 'feltiae' and 'intermedium' clades were characterized by having a vesicle. Expand
Macrogenomic Evidence for the Origin of the Black Fly Simulium suzukii (Diptera: Simuliidae) on Okinawa Island, Japan
TLDR
Of 41 macrogenomic rearrangements discovered in the five new cytoforms, four provide evidence for a stepwise origin of the Okinawan population from populations characteristic of the main islands of Japan. Expand
Harpellales (Zygomycota: Trichomycetes) associated with black flies (Diptera: Simuliidae): world review and synthesis of their gy and taxonomy ecolo
TLDR
The biology of Harpellales colonizing black flies is reviewed, a key to the species ofHarpellales that colonize black flies worldwide is presented, and commensalism, mutualism, and parasitis provide an enhanced framework for investigating trichomycete-host symbioses. Expand
Size variation of trichospores of Harpella melusinae in larval black flies.
TLDR
Trichospores of Harpella melusinae in larval black flies from four streams in northwestern South Carolina were measured and mean trichospore length differed significantly between seasons and between sampling sites but did not differ significantly between middle and final instars. Expand
Multiple symbiotes in larval black flies (Diptera: Simuliidae): associations of trichomycete fungi with ichthyosporeans, mermithid nematodes, and microsporidia.
TLDR
Aside from the consistent attachment of the trichomycete Simuliomyces microsporus to the ichthyosporean Paramoebidium chattoni, there is little evidence that prevalence and colonization levels of trICHomycetes were influenced by other symbiotes, including other trichometes. Expand
