The exsheathment and migration of Brugia pahangi microfilariae in mosquitoes of the Aedes scutellaris species complex. 1978

R R Owen

Studies on the Aedes scutellaris complex of mosquitoes showed that refractory and susceptible species can be distinguished by reference to the proportion of Brugia pahangi microfilariae which reach the thorax within three hours of a feed. Migration ceased approximately 1 1/2 hours after feeding in refractory species, in which only 50% of the ingested worms reached the thorax, In susceptible species over 95% of the ingested microfilariae reached the thorax, and migration lasted for three hours after a feed. Differentiation could be achieved by studying the levels of exsheathment, but it is suggested that analysis of migration levels forms a reliable, accurate and quick method of distinguishing refractory from susceptible species.

UI	MeSH Term	Description	Entries
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements

D000330	Aedes	A genus of mosquitoes (CULICIDAE) frequently found in tropical and subtropical regions. YELLOW FEVER and DENGUE are two of the diseases that can be transmitted by species of this genus.	Aede
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
