microfilaria - periodicity

conc.: microfilariasis

In medical textbooks, it is written:

"Microfilaria have a typical periodicity in peripheral blood, 
e.g. Wuchereria bancrofti and Brugia malayi at night or Loa loa 
at noon."

My question:

What happens when the patient is transferred by plane, lets say 
from Asia to Europe. Do microfilaria have a strict 24h 
periodicity, that means: in Europe Wuchereria bancrofti will 
appear in peripheral blood in the afternoon, or do they have a 
day-light triggered cycle?

Who has experience about this?
