Predator, Parasitoid, dan Hiperparasitoid yang Berasosiasi dengan Kutudaun (Homoptera: Aphididae) pada Tanaman Talas

Abstract

Predators, parasitoids and hyperparasitoids associated with aphids on Caladium crop were identified. Two aphid species, i.e. Aphis gossypii (Glover) and Pentalonia nigronervosa Coq. A. gossypii colonies were frequently encountered during observations than that of P. nigronervosa. Five species of predators were found associated with A. gossypii colonies, i.e.: Coccirzella sp., Menochilus sp., Scyrnnus sp. (Coleoptera: Coccinellidae), Pseudodorus sp. (Diptera: Syrphidae), and Micromus sp. (Neuroptera: Hemerobiidae). Five parasitoid species were found associated with A. gossypii colonies, i.e. Aphidius delicatus Baker, Aphidius sp., Diaeretiella sp., Trioxys sinensis Mackauer (Hymenoptera: Aphidiidae), and Aphelinus sp. (Hymenoptera: Aphelinidae). Two hyperparasitoids in the genera Ooertcyrtus (Hymenoptera: Encyrtidae) species were found associated with the parasitoids. The diversity of natural enemies of, pest in sects in Caladium crop, could be potential for biological control of aphids in other crops. For instance Caladiurr~c an be grown as margin crop which function as a source as well as refugiurn of parasities and predators attacking aphids on the main crop.
