Genotype x environment (G x E) interactions frequently complicate breeding efforts and delay progress in selection. The cassava green spider mite (CGM) (Mononychellus tanajoa Bondar) is a serious constraint to Cassava production in Africa. Nine cassava genotypes were grown at 6 representative loc...
and influenced the relative ranking of genotypes across environments. The magnitude 01 the G x E interaction effect for CGM was higher than that for genotypes. Clone 63397 had the smallest interaction for CGM, showing stability in response to the pest across agroecologies. TME 1 suffered the leas...
The within-plant distribution of the cassava green spider mite, Mononychellus tanajoa Bondar, and the anatomical characteristics and the chemical components relating to varietal resistance of cassava, were studied using 11 cassava genotypes with varying levels of resistance for two dry seasons an...
The attraction of the predatory mites, Typhlodromalus manihoti and Typhlodromalus aripo, to the host plant-spider mite complex, Manihot esculenta–Mononychellus tanajoa, was investigated with a Y-tube olfactometer. Factors examined included predator starvation period, several combinations of cassa...
The cassava green mite Mononychellus tanajoa (Bondar) (Acari: Tetranychidae) is one of the most important pests of cassava, a main staple food crop in Tanzania. The International Institute of Tropical Agriculture (ETA) in collaboration with the Tanzania National Biological Control P r o m (NBCP) ...
Neozygites tanajoaeis a host-specific acaropathogen introduced in the late1990s from Brazil into cassava fields in West Africa for biocontrol ofthe cassava green mite (Mononychellus tanajoa). Local African isolates ofN. tanajoaeare morphologically similar to introduced Brazilian strainsbut the ...
The predatory mite Typhlodromalus aripo and the entomopathogenic fungus Neozygites tanajoae, both introduced from Brazil for control of the cassava green mite (CGM) Mononychellus tanajoa, now co-occur in cassava fields in Benin. However, studies on interactions between these two natural enemies a...
Various foods associated with cassava were tested for their effect on the development, fecundity and longevity of Euseius fustis, the most common phytoseiid species found on cassava in Africa. Euseius Justis developed successfully to adulthood on the spider mite prey species Mononychellus tanajoa...
The germination of capilliconidia of Neozygites floridana on the cassava green mite, Mononychellus tanajoa, and the viability of these conidia collected on glass coverslips were studied at different temperatures, humidities (expressed as saturation deficit (SD), measured in mg Hg), and light cond...
