The emergence rate and adult survival (longevity) of Japanese strains of Cu
lex pipiens molestus and Culex quinquefasciatus were compared at temperatur
es of 21, 25, and 30 degrees C. The pupation and emergence rates in both st
rains were higher at 21 and 25 degrees C than at 30 degrees C. The adult em
ergence rate, especially in females, was lower in Cx. p, molestus than in C
x. quinquefasciatus. Longevity of females and males was lower in Cx. p. mol
estus at 25 degrees C and above. The survival of Cx, p. molestus was advers
ely affected by temperatures of 28 degrees C and higher. High temperature m
ay restrict the distribution of this species. Therefore, if Cx. p. molestus
infests the Okinawa region, the likelihood that it will become established
is minimal.
