Abstract

The leucaena psyllid, Heteropsylla cubana, was studied under constant temperatures ranging from 21.5 to 35.0°C. Total mean development time was 11.2, 9.6 and 8.1 days at 21.5, 25.0 and 30.0°C respectively. For these temperatures, the mean number of eggs laid was 532.3, 758.3 and 374.7 with hatch rates of over 90%. At 35.0°C, a mean of only 4.5 eggs/female were laid in 24 h, egg hatch (9.0%) was very low and nymphs did not complete their development. Nymphal survival was only 65% at 30.0°C, compared to 84.2 and 87.6% at 21.5 and 25.5°C, respectively. Adult longevity was highest at 25.0°C; females outlived males at all temperatures. Age-specific life table statistics are given for the three temperatures. The calculated intrinsic rates of natural increase (rm) at 21.5, 25.0 and 30.0°C were 0.226, 0.293 and 0.324 respectively. Relative humidities in the range of 25 to 84% did not affect egg hatching, nymphal survival, or adult emergence of H. cubana.

Résumé

Le leucaena psyllid, Heteropsylla cubana a été étudié sous des températures constantes variant de 21,5 à 35,0°C. Le temps moyen total de développement était 11,2, 9,6 et 8,1 jours à 21,5, 25,0 et 30,0°C respectivement. Pour ces températures, le nombre moyen des oeufs pondus était 532,3 758,3 et 374,7 avec des taux d'éclosion au-dessus de 90%. A 35,0°C un moyen de 4,5 oeufs/femelle seulement ont été pondus dans 24 h, l'éclosion (9,0%) était très basse et les nymphes n'ont pas complété leur développement La survie nymphale n'était que 65% à 30,0°C, en comparaison à 84,2 et 87,6% à 21,5 et 25,5°C respectivement. La longévité adulte était plus élevée à 25,0°C; les femelles ont survécu les mâles à toutes les températures. Les statistiques des tables de survie spécifique à l'âge sont présentées pour les trois températures. Les taux intrinsèques calculés de l'accroissement naturel (rm) à 21,5, 25,0 et 30,0°C étaient 0,226, 0,293 et 0,324 respectivement. Les humidités relatives dans les écarts de 25 à 84% n'ont pas affecté l'éclosion des oeufs, la survie nymphale, où l'emergence adulte de H. cubana.
