Nosema (microsporidian)

Nosema (microsporidian) is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nosema (microsporidian) rather than just read about it. In short: Nosema is a genus of microsporidian parasites. The genus, circumscribed by Swiss botanist Carl Nägeli in 1857, contains 81 species.

Key takeaways

Nosema (microsporidian) belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nosema (microsporidian) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nosema (microsporidian) from memory before moving on to harder problems.

Reference excerpt

Nosema is a genus of microsporidian parasites. The genus, circumscribed by Swiss botanist Carl Nägeli in 1857, contains 81 species. Most parasitise insects and other arthropods, and the best-known Nosema species parasitise honeybees, where they are considered a significant disease by beekeepers, often causing a colony to fail to thrive in the spring as they come out of their overwintering period. Eight species parasitize digeneans, a group of parasitic flatworms, and thus are hyperparasites, i.e., parasites of a parasite.

Species Nosema algerae parasitising mosquitoes Nosema antheraeae parasitising the Chinese oak silkworm Antheraea pernyi Nosema apis parasitising western honey bees Nosema birgii parasitising the chrysomelid beetle Mesoplatys cincta Nosema bombi parasitising bumble bees Nosema bombycis causes pébrine in silkworms Nosema carpocapsae parasitising Laspeyresia molesta (a tortricid moth) Nosema ceranae parasitising honey bees and bumble bees Nosema chaetocnemae parasitising the chrysomelid beetle Chaetocnema tibialis Nosema chrysorrhoeae parasitising the browntail moth Euproctis chrysorrhoea (a lymantrid moth) Nosema couilloudi parasitising chrysomelid beetles of genus Nisotra Nosema empoascae parasitising the potato leaf-hopper Empoasca fabae (a cicadellid bug) Nosema equestris parasitising the chrysomelid beetles Gastrophysa viridula and Leptinotarsa decemlineata Nosema fumiferanae parasitising the eastern spruce budworm Choristoneura fumiferana (a tortricid moth) Nosema furnacalis parasitising the Asian corn-borer Ostrinia furnacalis (a pyralid moth) Nosema galerucellae parasitising the chrysomelid beetle Galerucella luteola Nosema gastroideae parasitising the chrysomelid beetle Gastrophysa polygoni Nosema granulosis parasitising the crustacean Gammarus duebeni Nosema kovacevici Nosema leptinotarsae parasitising the Colorado potato beetle (Leptinotarsa decemlineata) Nosema nisotrae parasitising chrysomelid beetles of genus Nisotra Nosema oulemae parasitising the chrysomelid beetle Oulema melanopus Nosema phyllotretae parasitising the chrysomelid beetles Phyllotreta atra and Phyllotreta undulata Nosema polygrammae parasitising the chrysomelid beetle Polygramma undecimlineata Nosema portugal parasitising the gypsy moth Lymantria dispar (a lymantrid moth) Nosema pyrrhocoridis parasitising the red soldier bug Pyrrhocoris apterus (a pyrrhocorid bug) Nosema pyrausta parasitising the European corn-borer Ostrinia nubilalis (a pyralid moth) Nosema serbica parasitising the gypsy moth Lymantria dispar (a lymantrid moth) Nosema spodopterae parasitising the diamondback moth, Plutella xylostella (a plutellid moth) Nosema trichoplusiae parasitising the cabbage looper/tiger moth Trichoplusia ni (a noctuid moth) Nosema tyriae parasitising the cinnabar moth Tyria jacobaeae (an arctiid moth) Nosema vespula parasitising European wasps Nosema locustae, which parasitises locusts and grasshoppers, and Nosema grylli, which parasitises crickets, have been transferred to Paranosema, or in the former case Antonospora. Nosema algerae, which parasitises anopheline mosquitoes, has been transferred to Brachiola. Nosema kingii, which parasitises fruit flies, and Nosema acridophagus, which parasitises grasshoppers, have been transferred to Tubilinosema. Studies of DNA sequences imply that the boundaries between the genera Nosema and Vairimorpha are incorrectly drawn.

Worked examples

Example 1 — a first encounter with Nosema (microsporidian)

Start with the simplest possible case. Write down what Nosema (microsporidian) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nosema (microsporidian) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nosema (microsporidian) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nosema (microsporidian)

In research: Nosema (microsporidian) appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nosema (microsporidian) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nosema (microsporidian) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Microsporidia genera, Parasites of arthropods, so understanding it makes those chapters shorter.
In everyday life: Look for Nosema (microsporidian) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
