EFFECT OF SOME POWDERS AND HIVE PRODUCTS ON LARVAL HAEMOLYMPH OF SILKWORM [PDF]

Journal of Plant Protection and Pathology, 2012
Two doses (5 and 10 gms) of 14 powders (hive products and plant materials) were added to mulberry leaves, and two levels (%) of 14 liquid treatments (hive products, honey, pollen, royal jelly and propolis and their mixtures) were sprayed on mulberry leaves which feed to 4th and 5th instar larvae of silkworm.  Effects on haematological characters, Total

Development time, mortality, and bioenergetic responses of larvae of the giant barnacle Austromegabalanus psittacus (Molina 1788) under controlled hatchery conditions of temperature and salinity

Aquaculture Reports
Barnacle production is a new aquaculture activity, that has developed to a semi-industrial level with extensive cultures in floating systems. However, the mass culture of larvae and juveniles under controlled hatchery conditions have not yet been ...

Silk Gland Factor 1 Plays a Pivotal Role in Larval Settlement of the Fouling Mussel Mytilopsis sallei

Biology
Most fouling organisms have planktonic larval and benthic adult stages. Larval settlement, the planktonic–benthic transition, is the critical point when biofouling begins.

Geostatistical evaluation of integrated marsh management impact on mosquito vectors using before-after-control-impact (BACI) design

International Journal of Health Geographics, 2009
Background In many parts of the world, salt marshes play a key ecological role as the interface between the marine and the terrestrial environments. Salt marshes are also exceedingly important for public health as larval habitat for mosquitoes that are ...

Effects of larval foam-making and prolonged terrestriality on morphology, nitrogen excretion and development to metamorphosis in a Leptodactylid frog [PDF]

PeerJ
At ontogenetic transitions, animals often exhibit plastic variation in development, behavior and physiology in response to environmental conditions. Most terrestrial-breeding frogs have aquatic larval periods.

Trophic cues as possible triggers of mussel larval settlement in southeastern Brazil

Aquatic Living Resources, 2018
Oligotrophic conditions may impose a nutritional challenge for the larval and early post-larval development of bivalves during the search for a suitable benthic habitat. Here we investigated what settlement cues might be important for mytilid populations

Development and silk production by silkworm larvae after topical application of methoprene

Scientia Agricola, 2002
Juvenile hormone analogues have been tested as insect growth regulators in silkworm (Bombyx mori), seeking an increment of silk production. These chemical products, when applied in small or moderate rates, promote the extension of the last larval instar.
