We have been rearing Rockefeller mosquitoes for many years in our laboratory without any problems, but lately, in spite of good viability of eggs and unchanged environmental conditions (27°C, 70%RH), the mosquitoes spend too much time in larval stages (until 3 weeks. Last year, the average time from L1 to L4 was 1 week).

Is there any physiological or genetic cause that generate this effect on the colony? This fact will have any effect on adult biology?

Thanks in advance
