Ca. Lanciani et Jf. Anderson, EFFECT OF PHOTOPERIOD ON LONGEVITY AND METABOLIC-RATE IN ANOPHELES-QUADRIMACULATUS, Journal of the American Mosquito Control Association, 9(2), 1993, pp. 158-163
The effect of photoperiod on longevity of nondiapausing members of a s
pecies in the mosquito species complex Anopheles quadrimaculatus was t
ested in laboratory experiments. First-generation adults reared from 2
field collections showed the same trends: those reared under short ph
otoperiod (8 h light: 16 h dark) lived longer than did those reared un
der long photoperiod (16 h light: 8 h dark). Adult metabolic rates wer
e not consistently related to longevity. In adults reared from the fir
st collection, metabolic rates were higher in long-photoperiod individ
uals but in adults reared from the second collection, metabolic rates
were higher in short-photoperiod individuals. Longevity appears to be
another of many insect features that are affected similarly by tempera
ture and photoperiod.
