Relative ovipostion rates of the cassava hornworm, Erinnyis ello L. (Lepidoptera:Sphingidae) and accompanying parasitism by Telenomus sphingus Ashmead (Hymenoptera: Scelionidae) on upper and lower leaf surfaces of cassava.
Entomophaga 34 (1), 73-76
Abstract: 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.
