Relative oviposition rates of the cassava hornworm, Erinnyis ello (Lep.: Sphingidae), and accompanying parasitism by Telenomus sphingis (Hym.: Scelionidae), on upper and lower leaf surfaces of cassava
Oviposition by the cassava hornworm, Erinnyis ello L., was quantified for upper (abaxial) and lower (adaxial) leaf surfaces of cassava in the department of Tolima, Colombia. Relative rates of egg parasitism by Telenomus sphingis Ashmead on the different leaf surfaces were determined and compared. Ap...

| description | Oviposition by the cassava hornworm, Erinnyis ello L., was quantified for upper (abaxial) and lower (adaxial) leaf surfaces of cassava in the department of Tolima, Colombia. Relative rates of egg parasitism by Telenomus sphingis Ashmead on the different leaf surfaces were determined and compared. Approximately 6% of hornworm eggs had been placed on lower leaf surfaces. These eggs showed significantly lower rates of parasitism indicating reduced searching time or efficiency by the parasitoid on leaf undersides. |

Relative rates of egg parasitism by Telenomus sphingis Ashmead on the different leaf surfaces were determined and compared. Approximately 6% of hornworm eggs had been placed on lower leaf surfaces. These eggs showed significantly lower rates of parasitism indicating reduced searching time or efficiency by the parasitoid on leaf undersides. L'abondance de la ponte de Erinnyis ello L. sur les faces supérieures (abaxial) et inférieures (adaxial) des feuilles de manioc a été évaluée dans le département de Tolima, Colombie. Les taux de parasitisme des œufs par Telenomus sphingis Ashmead sur les 2 types de surfaces ont été déterminés et comparés. Les résultats montrent qu'approximativement 6% des œufs de E. ello sont déposés à la face inférieure des feuilles. Les taux de parasitisme enregistrés pour ces œufs sont significativement plus bas que ceux enregistrés pour les œufs pondus à la face supérieure des feuilles. Ces résultats montrent un temps de recherche ou une efficacité réduite du parasite qui explore la face inférieure des feuilles. 1989-03 2014-10-02T08:33:08Z 2014-10-02T08:33:08Z Journal Article https://hdl.handle.net/10568/44035 en Limited Access Springer |
