Abstract

The effect of temperature on the rate of development ofAnastatus biproruli (Girault) was determined by rearing individuals on eggs ofBiprorulus bibax Breddin under a range of constant temperatures (17.5–40.0°C). Rate of development changed in a linear fashion from 17.5–35.0°C and the lower developmental threshold was estimated to be 12.8°C. An estimated 331.8 degree days were required for development. Survival of developing parasitoids was optimal (72–90%) between 25–35°C. Longevity of virgin adults ranged from 12–26 days at 22.5–35°C but was only 3.6 days at 37.5°C. Mated females produced a mean of 54.6 progeny during an average lifespan of 36.4 days at 30°C. Progeny were produced only during the first 21 days of adulthood but post-reproductive females still attacked and killed hosts. FemaleA. biproruli overwintered successfully, and were able to parasitise host eggs if direct sunlight was available.A. biproruli also overwintered as immature stages in host eggs. The biology ofA. biproruli is discussed with regard to its importance as a natural enemy ofB. bibax.

Résumé

L'effet de la température sur la vitesse de développement d'Anastatus biproruli a été étudié en élevant des individus sur des œufs deBiprorulus bibax dans une gamme de températures constantes (entre 17,5°C et 40°C). La vitesse de développement évolue de façon linéaire entre 17,5°C et 35°C et le scuil théorique de développement le plus bas se situe à 12,8°C. Une valeur estimée de 331,8 degrés-jour est nécessaire pour le développement complet. La survie des parasitoïdes en développement est optimale (72 à 90%) entre 25 et 35°C. La longévité des femelles vierges varie de 12 à 26 jours entre 22,5°C et 35°C mais elle est seulement de 3,6 jours à 37,5°C. Les femelles accouplées produisent une moyenne de 54,6 descendants pendant une durée de vie moyenne de 36,4 jours à 30°C. La descendance n'est produite que durant les 21 premiers jours du stade adulte mais les femelles après la période de reproduction attaquent et tuent encore des hôtes. Les femelles deA. biproruli hivernent avec succès et sont capables de parasiter des œufs-hôtes sous la lumière du soleil directe.A. biproruli hivernent aussi à l'état de stade immature dans les œufs de l'hôte. La biologie deA. biproruli est discutée en fonction de son importance en tant qu'agent de lutte biologique contreb. bibax.
