Abstract
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.Résumé: Résistance au jeûne et accumulation de lipides chez Cletus punctiger diapausants ou non‐diapausantsLa résistance au jeûne, définie comme la longévité en présence d'eau mais sans aliment apr3ès une période d'alimentation, a été examinée au laboratoire en jours longs (n'induisant pas de diapause imaginale) et courts (induisant une diapause imaginale) chez C. punctiger. Le jeûne dès l'émergence des adultes réduit la longévité à 8–10 jours pour les deux types d'adultes. Pour les adultes diapausants lorsque la période d'alimentation préalable a duré jusqu'à 20 jours, plus longue était cette période d'alimentation, plus la longévité était importante. Pour les adultes non‐diapausants, la longévité a été augmentée par les 5 premiers jours d'alimentation, mais non par une alimentation prolongée au‐delà. La quantité de lipide accumulée par l'alimentation après l'émergence des adultes est utilisée pour expliquer cette différence. La discussion porte sur la signification biologique de la résistance au jeûne.Keywords
