Abstract
The biology ofHyperaspis jucunda (Muls.) was studied at 27°C and the incubation period averaged 5.1 days. The 1st, 2nd, 3rd and 4th larval instar averaged 2.5; 2.8; 3.4 and 5.0 days respectively. Larval development was completed in about 13.8 days while it took 7.1 days for the pupae. The total developmental time averaged 26.4 days. Mean longevity was 100 and 101 days for males and females respectively. The premating period was 19–24 h while the preoviposition period averaged 6.3 days. The generation cycle (egg to egg) averaged 32.8 days. The oviposition period was about 93 days during which an average female laid 456 eggs.
Résumé
La biologie deHyperaspis jucunda (Muls.) a été étudiée à 27°C. La période moyenne d'incubation fut de 5,1 j. Les ler, 2e, 3e et 4e stades larvaires ont duré en moyenne 2,5; 2,8; 3,4 et 5,0 j, respectivement. L'état larvaire a demandé 13,8 j et l'état nymphal 7,7 j. La moyenne du temps total de développement fut de 26,4 j. La longévité a été de 100 et 101 j en moyenne pour les adultes mâles et femelles respectivement. Une période de 19–24 h précède l'accouplement chez les femelles fraîchement écoloses. La période de préoviposition a duré 6,3 j. Le cycle d'une génération (période de l'œuf à l'œuf) fut de 32,8 j en moyenne et la période moyenne d'oviposition de 93 j durant laquelle une femelle pond 456 œufs.
