Starvation longevity and lipid accumulation in non-diapausing and diapausing adults of the coreid bug Cletus punctiger
1986
Ito, Kiyomitsu
The starvation longevity, which is expressed as the longevity without food but water after a given period of feeding, in adult Cletus punctiger (Heteroptera: Coreidae) was studied under a long (inducing non-diapausing adult) and a short (inducing diapausing adult) daylength in the laboratory. Both non-diapausing and diapausing adults starved since adult emergence had short (8-10 days) longevities. The starvation longevity of diapausing adults was extended up to 20 days of adult feeding. On the other hand, the starvation longevity in non-diapausing adults was extended by feeding in the first 5 days but it was not extended any more by the longer feeding. This difference was considered to depend on the lipid content which had been accumulated by adult feeding only in diapausing insects.
