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. ...

Morphological description and illustration of the female developmental stages of Stictococcus vayssierei (Homoptera: Stictoccocidae)

Autor: Tindo, M. Doumtsop, A. Goergen, Georg E. Hanna, R.

The African root and tuber scale Stictococcus vayssierei Richard is the only known hypogeal species of the family Stictococcidae. Its wide range of host plants together with concurrently field observed differences in host preference provided evidence of polyphagy or the involvement of more than a...
