Distribution and production of the larval chironomid populations in Tjeukemeer
Hydrobiologia, 1982The 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 ...

The effect of larval nutrition on egg production in Rhodnius prolixus
Journal of Insect Physiology, 1979Abstract Rhodnius prolixus adults which had fed to repletion at each larval instar were frequently autogenous, while those allowed to take only partial blood meals at the 3rd, 4th and 5th larval instars were always anautogenous. Bugs fed to repletion at each larval instar had large abdominal fat bodies throughout adult life.

The effect of larval and adult nutrition on successful autogenous egg production by a mosquito
Journal of Insect Physiology, 2004Females of most mosquito species require a blood meal to provision eggs and can be medical problems because of this dependency. Autogenous mosquitoes do not require blood to mature an initial egg batch and, instead, acquire nutrients for egg provisioning as larvae.

Anisakis simplex: The activity of larval products on the complement system
Experimental Parasitology, 2007The 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

BIODIGESTION OF SILKWORM. LARVAL LITTER FOR BIOGAS PRODUCTION
Madras Agricultural Journal, 1990Tho possibility of utilizing silkworm larval litter (SLL) as an alternative or supplementary feedstock with coudung for biogas production was studied under laboratory conditions. Incorporation of SLL enhance the generation of biogas in all treatments.

The production and characterisation of monoclonal antibodies to Lucilia cuprina larval antigens
International Journal for Parasitology, 1994A 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 ...

Larval productivity of Fasciola gigantica in two lymnaeid snails
Journal of Helminthology, 2004AbstractTwo 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.

Moulting hormone production in the isolated larval abdomen of the Colorado beetle
Nature, 1975IN spite of the overwhelming evidence for the essential roles of the prothoracic glands in the synthesis of moulting hormone and the regulation of insect moulting and development1–3, several instances of moulting without prothoracic glands have been reported, either by extirpation (Galleria mellonella4 and Periplaneta americana5) or by ligation ...

Influence of Rat Strain on Larval Production by the Parasitic Nematode Strongyloides ratti
The Journal of Parasitology, 1998The course of infection with Strongyloides ratti in a range of rat strains was assessed by monitoring the production of larvae. To our knowledge, this is the first such study of S. ratti using its natural host Rattus norvegicus. Host strain influenced the pattern of larval production. The results were qualitatively the same for 2 S.

Equine antibody response to larval Parascaris equorum excretory-secretory products
Veterinary Parasitology, 2016Parascaris 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.
