Autor: Gold, CS Altieri, Miguel A. Bellotti, Anthony C.

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...

Journal Article 1989

Autor: Urias López, Mario Alfonso Bellotti, Anthony C.

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...

A Phenaccocus herreni Cox & Williams population studied in Colombia, S.A., across a complete cassava crop cycle did not exceed 81 mealybugs/plant. P. herreni densities in Colombia were highest in the dry season, as were levels of parasitism by the encyrtids Acerophagus coccois Smith and Epidinoca...

Journal Article 1983

Autor: Farias, A.R.N. Bellotti, Anthony C.

In order to determine the degree of parasitism of Erinnyis ello and E. alope eggs by Trichogramma and Telenomus under field conditions, 113 samples were collected, without determined dates, from Sept. 1978-March 1980, in Cruz das Almas, BA, Brazil, throughout the whole cassava cycle. Eggs were ta...
