Influence of magnetic field on biological system has been reported. The study reveals effect of magnetization of Bombyx mori larvae on the total protein content level in the silk gland, fat body and haemolymph of fifth instar larvae. First instar larvae were magnetized in 1000, 2000, 3000 and 4000 Gauss magnetic field for 30 minutes in a day till first moulting. Variation in the strength of mag...
Samia cynthia ricini (Lepidoptera: Saturniidae) is an important commercial silk-producing insect; however, in contrast to the silkworm, mulberry leaves are toxic to this insect because the leaves contain the component 1-deoxynojirimycin (DNJ). A transcriptomic analysis of eri-silkworm haemolymph was conducted to examine the genes related to different metabolic pathways and to elucidate the mole...
abstract: mostly honey bee consumes pollen as fermented and fermentation improves foods biological value in some cases. in this study we evaluate the nutritional effects of fermented diets on honey bee body protein and brood rearing in colonies. this experiment conducted on honey bee colonies with different diets in a completely randomized design with 6 treatments and 7 replicates for 50 days....
Bees, as the main pollinators of food crops, represent a critical natural resource which needs to be carefully exploited and managed. In recent years, however, destruction of bee's native habitats, infestations, and displacements of native bees by alien bee species have reduced and disturbed bee populations and this is already having considerable impact on global agriculture. A further concurre...
A better knowledge of the physiological basis of salinity tolerance is essential to understanding the ecology and evolutionary history of organisms that have colonized inland saline waters. Coleoptera are amongst the most diverse macroinvertebrates in inland waters, including saline habitats; however, the osmoregulatory strategies they employ to deal with osmotic stress remain unexplored. Survi...

Bee product mugwort is identified as being at the origin of allergic accidents but the biological potency of Artemisia contained in bee pollen is not well known. In this experiment, Artemisia mass was identified in bee pollen mass and after having calculated the proportion of Artemisia using the bee pollen melissopalynology spectrum. Skin reactivity to Artemisia was assessed by measuring wheal ...
honey bee sting is used in some societies as a treatment of inflammation in joint diseases such as arthritis. to investigate the effect of honey bee venom in reducing inflammation, we selected 30 male wister rats which were divided in to 6 groups. except group 1, all remaining groups received 0.5 ml of complete freund’s adjuvant to induce arthritis. after 9 days, all animals that received adjuv...
The nervous system of the opisthobranch mollusc, Aplysia califomica Cooper has been extensively studied and a great deal is known about the electrophysiological properties of a number of identifiable neurones (see Kandel, 1976, 1979). A variety of synaptic and electrical connections have been mapped, permitting identification of the mode in which nervous control is exerted over certain motor fu...
The transport of ammonia by various tissues throughout the body is of fundamental importance for nitrogen excretion in invertebrates, yet sites and mechanisms of ammonia transport are not presently well understood. In this thesis a novel ammonium-selective microelectrode was developed using the crown ether ionophore TD19C6, which is approximately 3800-fold more selective for NH 4 + than Na + co...
