	Sphaerularia Bombi ''Sphaerularia bombi'' is an entomopathogenic nematode. It is parasite of bumblebees. It infects and sterilizes gynes or potential queens of bumblebees. Life Cycle ''Sphaerularia bombi'' is a nematode that infects hibernating bumblebees. Bumblebees start seeking out a hibernation site for the winter season during fall and autumn. ''S. bombi'' would cause the infected bee multiple fail attempts to burrow into the ground, and with each fail attempt hundreds of 3rd stage larvae would be discharged from the bee's anal opening. The larvae would eventually develop into the 4th larvae stage, this is the period where the infected bee dies. When a healthy bee finds its hibernation site, the 3rd stage larvae would infect the bee by penetrating it. The bee emerges to the surface during the spring season, and by that time the nematodes has developed into a mature female producing eggs within the bumblebee; 1st larvae stage. The eggs then hatches and molts into the 2nd larvae stage, which the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Sphaerularia Vespae ''Sphaerularia vespae'' is an endoparasitic nematode that infects the Japanese yellow hornet, ''Vespa simillima''. It invades and resides in the gaster (abdomen) of female hornets where it grows and develops. Because ''S. vespae'' sterilizes its host, it is also known as a parasitic castrator. After '' S. bombi'', it is the second recognized species of the genus ''Sphaerularia''. Diagnosis ''Sphaerularia vespae'' is characterized by the round, finger-like tip tail of females and the conspicuous male bursa. These features are used to distinguish ''S. vespae'' from ''S. bombi''. In addition, the square head shape of parasitic juveniles also distinguishes ''S. vespae'' from ''S. bombi,'' which have a more round, dome-shaped head. Distribution ''S. vespae'' has been found at several sites in Sapporo, Hokkaido, Japan ( Hitsujigaoka, Mount Moiwa and Shiraikawa Sapporo), and in Nishi-Nopporo, Ebetsu, Hokkaido. Life cycle ''S. vespae'' ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Nematodes The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time.
