Kimwe n’izindi Aedes nyinshi,umubu w’ingabo nturumana, nta n’ubumara ugira.Ingore ni yo igendana ubwo burozi.No mu miterere biratandukanye.Uw’ingabo urarambuye bihagije(iriya 2 ihagaze) naho uw’ingore ni mugufi ukagira n’akada gatukuye cyane.
b)Mu bindi bihugu nk’Uburayi:
Mu bindi bihugu bigira igihe kinini cy’ubukonje,hagaragara umubu wa Aedes albopictus utera amagi iyo hatangiye gushyuha(mai-novembre).Uyu mubu uboneka no mu mijyi ikomeye aho utera amagi mu mazi yaretse mu bikoresho nk’ibikombe by’indabo cyangwa by’imitako,mu mapine,mu bintu bya plasitiki kimwe n’imirereko itamena amazi neza.

Uko hashyushye ni ko utera magi menshi kandi niko uramba.Utera amagi 74 mu minsi 4,ukabaho iminsi 29 ahari ubushyuhe bwa degré 25°C,n’iminsi 32 ahari ubwa degré 30°.

Ikiwutandukanya na Aegipti ni amaguru yawo afite amabara y’umweru ukeye mu mukara mwinshi.Ni nacyo gituma witwa moustique-tigre.
