Larval productivity of Fasciola gigantica in two lymnaeid snails

Journal of Helminthology, 2004
AbstractTwo groups of Galba truncatula and two groups of Lymnaea natalensis were experimentally infected with Fasciola gigantica to determine if snail species had an influence on the redial burden and cercarial shedding of this trematode when snails of both species were infected with the same isolate of miracidia.

Equine antibody response to larval Parascaris equorum excretory-secretory products

Veterinary Parasitology, 2016
Parascaris equorum is an intestinal nematode of foals and young horses that can produce mild to severe pathology. Current diagnosis is limited to detection of patent infections, when parasite eggs are identified during fecal examinations. This study examined the use of larval P.

Impacts of black soldier fly, (Diptera: Stratiomyidae) larval frass on tomato production

Journal of Economic Entomology, 2023
Abstract The “insects as food and feed” movement is gaining considerable momentum as a novel means to provide protein to people (i.e., food) and other animals (i.e., feed). Insects require significantly fewer resources, such as water and land, to produce, process, and distribute as a food or feed source.

Anisakis simplex: The activity of larval products on the complement system

Experimental Parasitology, 2007
The effects of the larval products (crude extract and excretory-secretory) of Anisakis simplex on the classical and alternative pathways of human complement system were investigated. This could constitute a mechanism to evade host defences, similarly than in other parasitic diseases. The larval products showed a stronger effect on the classical pathway

Distribution and production of the larval chironomid populations in Tjeukemeer

Hydrobiologia, 1982
The distribution and production of larval chironomids in Tjeukemeer, a shallow, moderately large and wind exposed lake, were estimated between 1969 and 1972. The following seven species together contributed more than 95% of all the individuals collected: Chironomus anthracinus, Chironomus plumosus, Cladotanytarsus mancus, Glyptotendipes pallens ...

Intensive larval husbandry and fingerling production of cobia Rachycentron canadum

Aquaculture, 2008
Abstract Methods and results of two larval rearing trials of cobia (Rachycentron canadum) are presented. These trials were designed to test the efficacy of protocols developed over several years of research in cobia larviculture at the UMEH. The protocols incorporate the use of probiotics and prophylaxis, minimize microalgae use, and include ...

Larval fish production in the tidal River Elbe 1985–1986

Journal of Fish Biology, 1991
In 1985 and 1986 ichthyoplankton composition was studied during seven sampling series at 37 stations along the tidal Elbe and its tributary rivers between Hamburg harbour and the North Sea. The highest larval density was observed in May and April. No, or very few, larvae occurred from late summer to early spring.

The production and characterisation of monoclonal antibodies to Lucilia cuprina larval antigens

International Journal for Parasitology, 1994
A panel of murine monoclonal antibodies was produced against three Lucilia cuprina larval preparations that are unlikely to be exposed to the sheep's immune system during a normal infection. Antibodies were successfully produced against a crude third instar midgut homogenate preparation (MG), and Sodium dodecyl sulphate (SDS) and Triton X-114 (TX ...

Relations between Egg Production, Larval Production and Spawning Stock Size in Clyde Herring

1974
In 1957 the Marine Laboratory, Aberdeen conducted a preliminary survey of herring egg and larval distributions over Ballantrae Bank, the main spawning ground of the Clyde spring-spawning herring stock. In 1958 more systematic surveys were begun and, with some breaks due to unavailability of research vessels at the appropriate times, these have been ...
