Effect of competition between Aphytis chrysomphali (Mercet) and A. melinus (Hymenoptera:Aphelinidae), on their coexistence and efficacy as biological control agents of Aonidiella aurantii (Hemiptera: Diaspididae)
The California red scale Aonidiella aurantii is considered a key citrus pest. Parasitoids of genus Aphytis are the most important natural enemies of A. aurantii. In the Mediterranean basin, the native A. chrysomphali and the introduced A. melinus are the most abundant parasitoids of A. aurantii. The...

| Sumario: | The California red scale Aonidiella aurantii is considered a key citrus pest. Parasitoids of genus Aphytis are the most important natural enemies of A. aurantii. In the Mediterranean basin, the native A. chrysomphali and the introduced A. melinus are the most abundant parasitoids of A. aurantii. The introduced has completely displaced the native A. chrysomphali in the south, whereas they coexist in the north-east of the Iberian Peninsula. We have used this well-known host-parasitoid system to investigate some gaps on the behavioural ecology of hymenopteran parasitoids, which have been exposed in the introduction. This knowledge will contribute to improve their use in biological control programs, especially in the case of A. aurantii in the Mediterranean basin. |
