Conference Paper 2009

Autor: Hountondji, F.C.C. Sabelis, M. Hanna, R.

The role of infochemicals in mediating interactions between herbivores and their foraging natural enemies, mainly predators and parasitoids, is well established, but very little is known about infochemical use in interactions between herbivores and their sit-and-wait pathogens. This paper reviews...

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. ...

The survival of Neozygites cf. floridana (Weiser and Muma) as dry hyphal bodies in mummified cassava green mites, Mononychellus tanajoa (Bondar), at 5.0% RH in the dark was affected by storage temperature. Survival of the fungus in mummies kept at 24 + 1.0°C could be demonstrated for 6-7 months. ...

A survey of the distribution and abundance of cassava green mite and associated indigenous natural enemies found in the cassava agroecosystem in Cameroon was conducted during the 1991 dry season (January-February). The survey area included nine of the ten provinces of the country and covered 4.2 ...

The need to evaluate non-target effects of classical biological control of arthropod pests has received considerable attention in recent years. We determined with repeated field surveys the changes in abundance and distribution of the phytoseiid mite fauna in cassava fields resulting from the int...

In 1980 major studies on entomology were directed to accumulating information on the complex of insects that attack the cassava crop, emphasizing biological control studies of important pests, especially Erinnyis ello and Phenacoccus sp. Basic studies on the stemborer (Chilomina clarkei) were con...

How the pathogen inoculum size affects the pathogenicity of Neozygites floridanatoMononychellus tanajoawas studied at 28°C, 12L:12D photoperiod and 90–100% RH. All inoculum sizes tested (one, two, four, six, and eight capilliconidia per mite) were lethal. Dead mites started to appear 48 hr after ...
