Abstract

Photoperiod induced dormancy for 14 North American strains of Aedes albopictus were determined at 21, 26 and 29 degrees C. Strains tested at 21 degrees C and intermediate temperatures of 25-27 degrees C demonstrated clear photoperiodic responses whereas temperatures of 29 degrees C and above, greatly reduced or negated diapause incidence. A suboptimal larval diet increased the percentage diapause in eggs laid by resulting adults. This larval diet was also associated with a slight increase in critical photoperiod.
