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...

In Africa the cassava green mite, Mononychellus tanajoa, is an important pest of cassava, Manihot esculenta. Phytoseiid mites from South America are being evaluated as potential biological control agents of this alien pest. We evaluated six phytoseiid (Acari: Phytoseiidae) species, collected in S...
