Journal Article 1996

Autor: Oduor, G.I. Yaninek, John S. Geest, L.P.S. van der Moraes, G.J. de

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...

Autor: Msikita, W. Yaninek, John S. Ahounou, M. Fagbemissi, R.

Fifty-five samples of diseased cassava (Manihot esculenta) crowns and shoots and discoloured chips were collected from Benin and Cameroon, Africa. Pieces of infected tissue were cultured on agar and incubated for a week. Over 36% of fungal isolates were Fusarium spp. Of the Fusarium isolates, 55%...

Density-specific sampling plans were developed under African conditions for the exotic spider mite, Mononychellus tanajoa (Bondar), a serious pest of cassava, Manihot esculenta. The within-plant distribution of Mononychellus tanajoa was found to favour new foliage, regardless of time of planting ...

Journal Article 1990

Autor: Yaninek, John S. Gutiérrez, A.P. Herren, H.R.

Seasonally dense populations of Mononychellus tanajoa (Bondar), feeding on the leaves of cassava, Manihot esculenta Crantz, significantly reduced the leaf, stem, and storage-root dry matter of mite-infested plants. Stressed plants met metabolic demands by remobilizing the dry matter in stems and ...

Laboratory and field experiments were performed to test several materials on their suitability as carrier for the aerial release of phyroseiid mites. Relatively few mites adhered to the materials. Nevertheless, mites were rettieved in cassava fields after a mass release, using oat flakes as carri...

A survey of the pathogenic fungi associated with mites on cassava in Benin, West Africa, revealed both geographical and seasonal variation in the presence of Neozygites cf. floridana (Weiser and Muma) and Hirsutella thompsonii Fisher on Mononychellus tanajoa (Bondar) and Oligonychus gossypii (Zac...
