The application of magnetic field on Bombyx mori cocoon has been proved to be of biotechnological significance in the sericulture industry. Variation in the static magnetic strength significantly influenced the glucose content in the fat body and haemolymph of Bombyx mori pupae. The experiments were conducted in the year 2007. The cocoons were magnetized for 24, 48, 72 and 96 h separately with ...

Host manipulation by parasites not only captures the imagination but has important epidemiological implications. The conventional view is that parasites face a trade-off between the benefits of host manipulation and their costs to fitness-related traits, such as longevity and fecundity. However, this trade-off hypothesis remains to be tested. Dinocampus coccinellae is a common parasitic wasp of...

This study investigated the copulatory behaviour of the lumbricid earthworm Eisenia fetida (Savigny, 1826) in a natural population, and the uniparental reproduction of E. fetida and E. andrei Bouché 1972, two closely-related species. Sperm transfer occurred in 61 % of the matings observed, of which 88.2 % showed bi-directional sperm transfer, 9.8 % unidirectional sperm transfer and one earthwor...

earthworms are an important part of food chain in soil ecosystem. in polluted soils, heavy metals are consumed by earthworms and transferred to other organisms through food chain, resulting in many adverse health impacts. due to the benefits of earthworms for soil fertility, it is important to assess the effects of soil pollution on population, biomass and functions of earthworms. to determine ...

Recognised for their diversity in apical structure morphology, members of the cestode order Lecanicephalidea Wardle et McLeod, 1952 known to date exhibit relatively mundane and uniform acetabular morphology. A new lecanicephalidean genus, Zanobatocestus gen. n., is proposed for two new species found parasitising the spiral intestine of the striped panray, Zanobatus schoenleinii (Müller et Henle...

In only a few decades, A. brllennichi has colonized vast areas of continental Europe. This was most likely achieved by the ballooning of young spiderlings. Its original distribution was largely restricted to the Meditenanean. This makes A. brllennichi an interesting object for studying the proximate factors, behavioural and micrometeorologicaL which lead to this rapid mode of dispersal. After e...
