Sampling Mononychellus tanajoa (Acari: Tetranychidae) on cassava in Africa

Autor: Yaninek, John S. Baumgaertner, J.U. Gutiérrez, A.P.

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 ...

Dynamics of Mononychellus tanajoa (Acari: Tetranychidae) in Africa: impact on dry matter production and allocation in cassava, Manihot esculenta

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 ...

Seasonal and habitat variability in the fungal pathogens, neozygites cf. floridana and Hirsutella thompsonii, associated with cassava mites in Benin

Autor: Yaninek, John S. Saizounou, Z. Onzo, A. Zannou, I. Gnanvossou, D.

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...

Interactions in an acarine predator guild: impact on Typhlodromalus aripo abundance and biological control of cassava green mite in Benin, West Africa

Autor: Onzo, A. Hanna, R. Sabelis, M.

To determine the impact of an acarine predator guild on the abundance of a shared herbivorous prey and its principal exotic predator, a series of surveys were conducted in ca. 200 cassava fields in swamp and non-swamp areas in southwestern Benin, West Africa. For each field, the surveys provided ...

Biological control of cassava green mite with exotic and indigenous phytoseiid predators—effects of intraguild predation and supplementary food

Autor: Onzo, A. Hanna, R. Negloh, K. Toko, M. Sabelis, M.W.

Intraguild predation, one aspect of predator–predator interaction, has received in recent years increasingly greater attention because of mounting evidence of the impact of predator–predator interactions on the structure of ecological communities and biological pest control. In laboratory experim...
