Parasites of larval black flies (Diptera: Simuliidae) in Thailand

MARIANNE SHOCKLEY STEPHENS The Effects of Algae on the Efficacy of Bacillus thuringiensis var. israelensis Against Larval Black Flies (Diptera: Simuliidae) in Laboratory Bioassays (Under the Direction of RAY NOBLET)

Species diversity of black flies (Diptera: Simuliidae) in Oriental region and molecular phylogeny of the subgenus Gomphostilbia members.

BACKGROUND & OBJECTIVES Black flies (Diptera: Simuliidae) are ecologically and medically important insects. Female adults of black flies are the solitary vectors of river blindness (onchocerciasis) and their larvae play a vital role in stream ecosystem. This study examined the distribution of black flies in the Oriental region and analyzed the phylogenetic relationship of the subgenus Gomphosti...

Development of Onchocerca volvulus (Filarioidea: Onchocercidae) in the West African black fly Simulium yahense (Diptera: Simuliidae) in Liberia.

Simulium yahense black flies infected with microfilaria of Onchocerca volvulus were kept in a defined insectary environment in Liberia, West Africa. A daily sample of infected flies was dissected for larvae developing in the thoracic muscles and examined for growth in stadial development. Microfilariae ingested by black flies transformed to the L1 larval stage without molting. Successive larval...

External Parasites of Horses

In Florida, horses have numerous arthropod pests. Most of these pests are considered external parasites as their attack on the horse is principally external, as opposed to internal parasites such as “worms” or nematodes and bots. The common external parasites include filth flies such as non-biting house flies and biting stable flies and occasionally horn flies, the numerous other blood-feeding ...

The roles of abiotic factors, dispersal, and species interactions in structuring stream assemblages of black flies (Diptera: Simuliidae)

UNLABELLED BACKGROUND The patterns and drivers of species assemblages represent the core of community ecology. We focus on the assemblages of a single family of ubiquitous lotic insects, the Simuliidae (black flies), of which the larvae play a critical role in resource turnover in steams. We use Mantel tests and null models to tease out the potential influence of abiotic stream conditions, s...
