Environment and hostplant genotype effects on the seasonal dynamics of a predatory mite on cassava in subhumid tropical Africa

Autor: Zundel, C. Nagel, P. Hanna, R. Korner, F. Scheidegger, Urs C.

In tropical dry seasons, survival of small arthropods such as predatory mites is often negatively affected by low relative humidity (RH). For species that do not diapause or migrate to refuges, the ability of the habitat to mitigate climatic conditions becomes crucial. ...

Living at the threshold: where does the neotropical phytoseiid mite Typhlodromalus aripo survive the dry season?

Autor: Zundel, C. Hanna, R. Scheidegger, Urs C. Nagel, P.

The establishment of the neotropical predatory mite Typhlodromalus aripo in sub-Saharan Africa has resulted in broadly successful biological control of the cassava green mite Mononychellus tanajoa throughout the cassava belt of Africa. In some mid-altitude areas and drier lowland savannahs of sub...

Ant diversity in dominant vegetation types of southern Cameroon

Autor: Fotso Kuate, A. Hanna, R. Tindo, M. Nanga, S. Nagel, P.

Ants have been shown as particularly affected by land disturbance through deforestation and conversion of forest to agriculture. The effect of land use change on ant diversity in the Congo Basin is not well known. We conducted intensive sampling along a gradient of increasing vegetation disturban...

Boric acid for suppression of the ant Anoplolepis tenella and effects on an associated scale insect pest Stictococcus vayssierei in cassava fields in the Congo Basin

Autor: Hanna, R. Kuate, A.F. Nanga, S.N. Tindo, M. Nagel, P.

The scale insect, Stictococcus vayssierei, is one of the major pests and constraints to cassava production in the Congo Basin. It is frequently found associated with the ground nesting ant, Anoplolepis tenella, under cassava plant. Amdro fire ant bait granules (contains 7.3 g/kg Hydramethylnon), ...

Arthropod diversity in Lama forest reserve (South Benin), a mosaic of natural, degraded and plantation forests

Autor: Lachat, T. Attignon, S. Djego, J. Goergen, Georg E. Nagel, P. Sinsin, B. Peveling, R.

Arthropod assemblages were examined in Lama forest reserve, a protected area situated in the Dahomey gap, southern Benin, composed of plantations, degraded forest and remnants of natural forest. The objectives were to compare assemblages in relation to forest type and use, to elucidate the value ...

Dead wood and saproxylic beetle assemblages in a semideciduous forest in Southern Benin

Autor: Lachat, T. Nagel, P. Cakpo, Y. Attignon, S. Goergen, Georg E. Sinsin, B. Peveling, R.

Saproxylic (dead wood associated) beetles play an important role in all forest ecosystems and are known to be highly susceptible to forest management and fragmentation. Contrary to temperate forests, there has been very little research on saproxylic beetle assemblages in tropical forests. In Afri...
