Abstract

Temperature influences the reproductive capacity of the Saissetia coffeae and its parasitoid. The lowering of temperatures increased the egg production of the scales. The high temperature (30°C) reduced the egg-laying of Metaphycus helvolus and resulted in a greater proportion of male progenies. However, oviposition and sex ratio of Scutellista cyanea were unaffected by high temperature. The high temperature too, accelerated the development of ovarian eggs of both parasitoids.

Résumé

La température influence la capacité reproductive de Saissetia coffeae et ses parasitoides. Diminution de la température augmente la fécondité des coccides. Les températures élevées reduisent la fécondité de Metaphycus helvolus et causent une proportion plus grande de progéniture male. Néanmoins, la fécondité et la raison sexue de Scutellista cyanea ne sont pas affectées par les températures élevées. La température haute accélère le développement des oeux ovarielles des deux parasitoides.
