'''Mnanasi''' (''Ananas comosus'') ni [[mmea]] katika [[familia (biolojia)|familia]] [[Bromeliaceae]] ya [[oda]] [[Poales]]
Mnanasi unakuzwa hasa kwa sababu ya [[matunda]] yake, yanayoitwa [[nanasi|mananasi]] Asili yake ni [[Amerika ya Kusini]] ingawa kwa sasa unakuzwa sehemu nyingi za [[dunia]]. ==Visumbufu vya mnanasi==
[[Kijidudu|Vijidudu]] vinavyomelea mnanasi huchangia kuleta hasara kubwa kote duniani katika uzalishaji wa mananasi<ref>Sipes, B.S., E.P. Caswell, J. Chen Sarah, and W. Apt, 2005. Nematodes parasites of pineapple In: Plant-Parasitic Nematodes in Subtropical and Tropical Agriculture, 2nd Edition (eds) M. Luc, R.A. Sikora, J. Bridge. pp: 709-731</ref>. [[Spishi]] zaidi ya mia moja za [[nematodi]] zimeripotiwa kuingia [[mzizi|mizizi]] ya mnanasi<ref>Sipes, B.S., E.P. Caswell, J. Chen Sarah, and W. Apt, 2005. Nematodes parasites of pineapple In: Plant-Parasitic Nematodes in Subtropical and Tropical Agriculture, 2nd Edition (eds) M. Luc, R.A. Sikora, J. Bridge. pp: 709-731</ref> na kutatiza matumizi ya madini na maji kwa mmea na kusababisha mimea kudumaa. Aina za vijidudu hivi ambavyo huadhiri mavuno ya mananasi sana ni spishi za nematodi kama vile ''Meloidogyne javanica'', ''M. incognita'', ''Rotylenchulus reniformis'' na ''Pratylenchus brachyurus''<ref>Sipes, B.S. and D.P. Schmitt, 2000. Rotylenchulus reniformis damage threshold on pineapple. Acta. Horticulturea, 529: 239-246</ref><ref> Sipes, B.S., E.P. Caswell, J. Chen Sarah, and W. Apt, 2005. Nematodes parasites of pineapple In: Plant-Parasitic Nematodes in Subtropical and Tropical Agriculture, 2nd Edition (eds) M. Luc, R.A. Sikora, J. Bridge. pp: 709-731</ref>.
''Helicotylenchus dihystera'' na ''Criconemella ornata'' (kwa [[Kiing.]] Ring nematode) pia hupatikana sana kwa [[shamba|mashamba]] ya mananasi ingawa huwa hawasababishi uharibifu wowote uonekanao<ref>Raski, D. J. and Krusberg, L.R. (1984). Nematode parasites of grapes and other small fruits. In: Nickle, W.R. (ed.) Plant and insect nematodes.

Huko [[Hawaii]], upungufu wa kiasi kikubwa wa uzalishaji wa mananasi umeripotiwa kutokana na uharibifu au maambukizo ya nematodi. Katika mashamba ya mananasi ya [[Queensland]], huko [[Australia]], ''M. javanica'' ameripotiwa kuwa spishi aliye na uharibifu zaidi kuliko aina zote za vijidudu vinavyomelea mananasi<ref> Stirling, G.R., (1993)., Nematodes. In Broadley, RH, Wassman, RC and Sinclair, E (eds) Pineapple: Pests and Disorders. Queensland Department of Primary Industries, Brisbane, pp: 21-29.</ref>.
