Aomongo, Christopher A.Kawuki, Robert S.Bellotti, Anthony C.Alicai, TitusBaguma, Yona K.Maruthi, M.N.Bua, AntonColvin, John[African cassava whitefly, Bemisia tabaci, resistance in African and South American cassava genotypes]African cassava whitefly, Bemisia tabaci, resistance in African and South American cassava genotypes

Aspects related to breeding programs in cassava, the impact of past strategies and exptl results related to them are discussed. Even though sources of resistance have been identified for the majority of the diseases and pests, in addition to tolerance to adverse edaphic and climatic factors, it i...


Lozano, J.C.Byrne, D.Bellotti, Anthony C.[Cassava/ecosystem relationships and their influence on breeding strategy]Cassava/ecosystem relationships and their influence on breeding strategy

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...

Bemisia tabaci (Gennadius) is one of the most important pests of cassava in Africa and several countries of Asia due to the damage caused by direct feeding, the excretion of honeydew, and its capacity as a vector of cassava mosaic geminivirus. There is a general consensus that B. tabaci is a comp...


Carabalí, A.Bellotti, Anthony C.Montoya Lerma, J[Biological parameters of Bemisia tabaci (Gennadius) Biotype B (Hemiptera: Aleyrodidae) on Jatropha gossypiifolia, Commercial (Manihot esculenta) and wild cassava (Manihot flabellifolia and M. carthaginensis) (Euphorbiaceae)]Biological parameters of Bemisia tabaci (Gennadius) Biotype B (Hemiptera: Aleyrodidae) on Jatropha gossypiifolia, Commercial (Manihot esculenta) and wild cassava (Manihot flabellifolia and M. carthaginensis) (Euphorbiaceae)

A survey for parasitoids of the whiteflies, Bemisia tuberculata Bondar, Trialeurodes variabilis Quantaince, T. vaporariorum (Westwood), Aleurotrachelus socialis Bondar, Tetraleurodes sp., Aleuroglandulus malangae Russell and Aleurodicus sp., was conducted in 6 cassava growing regions of Colombia ...

We investigated whether cassava plants that are infested by the cassava mealybug, Phenacoccus herreni (Pseudococcidae, Sternorrhyncha), emit attractants for the encyrtid parasitoids Aenasius vexans Kerrich, Apoanagyrus (Epidinocarsis) diversicornis Howard, and Acerophagus coccois Smith. Bioassays...


Bertschy, CTurlings, TCJBellotti, Anthony C.Dorn, S.[Chemically-mediated attraction of three parasitoid species to mealybug-infested cassava leaves]Chemically-mediated attraction of three parasitoid species to mealybug-infested cassava leaves

Little is known about the inheritance of agronomic traits in cassava (Manihot esculenta Crantz). The vegetative multiplication of cassava allows cloning of individual genotypes, and separates environmental from genetic variation in the within-family variation. Knowing the magnitude of between- an...

Chemical exclusion of predators with permethrin was used to test the effectiveness of the phytoseiid predator Amblyseius limonicus Garman and McGregor and a complex of minor predators in the biological control of tetranychid (Mononychellus spp., Tetranychus spp., and Oligonychus peruvianus McGreg...
