Abstract
The Nagasaki strain of the mosquito Aedes togoi was reared under 3 different combinations of temperature and photoperiod. At 27 °C and 16-h photophase (27 °C/16 h) diapause was not observed. At 15 /C/12 h, adults emerged without suspension of development during the larval stage but laid eggs that entered embryonic diapause. At 15 /C/10 h, the larvae entered diapause at the 4th instar and the resultant females laid nondiapausing eggs. The Nagasaki strain of Ae. togoi enters diapause either as embryos or as 4th-instar larvae in response to the 2-h difference in photophase at 15 °C. This alternative diapause occurs naturally in Nagasaki, where the species overwinters as either embryos or full-grown larvae.
