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 byTelenomus sphingis Ashmead on the different leaf surfaces were determined and compared. A...

The parasitism, development, and thermal requirements of Trichogramma exiguum and Telenomus sphingis, common parasitoids of Erinnyis ello eggs, were studied. Life statistics were also determined for each specie and temp. (20, 25, and 30 degrees C for both species; for T. sphingis 32.5 degrees C w...
