The effect of the application of ethyl parathion, trichlorfon, diflubenzuron, and Bacillus thuringiensis var. kurstaki to eggs of Erinnyis ello, before and after being parasitized by Trichogramma exiguum and Telenomus sphingis, was studied. Insecticides were also tested on the adults of these par...

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...

Cassava (Manihot esculenta) occupies a uniquely important position as a food security crop for smallholder farmers in areas of the tropics where climate, soils, or societal stresses constrain production. Given its reliability and productivity, cassava is the most important locally produced food i...

En Colombia existe un complejo de ocho especies de moscas blancas asociadas al cultivo de yuca. La especie predominante es Aleurotrachelus socialis Bondar la cual constituye el 92% de la población total y ocasiona pérdidas en rendimiento hasta del 79% en campos experimentales. Con el propósito de...

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...

Thrips palmi Karny es una plaga importante en varios cultivos, especialmente en hortalizas. El ácaro predador Neoseiulus cucumeris se ha usado con éxito para el control de especies de trips en varios cultivos y Typh1odromalus aripo tiene gran capacidad de consumir trips de yuca. Con el fin de eva...

Cyrtomenus bergi Froeschner es un fitófago subterráneo importante en cultivos tropicales. Se evaluaron dos cepas comerciales de nemátodos entomopatógenos (nep) (Steinernema feltiae (Filipjev) y Heterorhabditis bacteriophora Poinar) como antagonistas biológicas bajo invernadero (18-28°C y 55-85% h...
