Mite fauna associated with Amaranthus cruentus L. and Solanum macrocarpon L., two major indigenous leafy vegetables produced in Benin, was monitored in July-October 2004, on IITA-Benin Station where no pesticides were applied and on a farmer-managed vegetable farm near Abomey-Calavi with pesticid...

This is the seventh publication in a series concerning the phytoseiid mites of sub-Saharan Africa. Sixteen phytoseiid species of the subfamily Phytoseiinae (Chantia: 1 species, Phytoseius: 13 species and Platyseiella: 2 species) are reported in this paper. They include all species of this subfami...

To improve biocontrol of the cassava green mite, Mononychellus tanajoa, a series of screenhouse experiments were conducted on cassava to determine the effects of single and combined releases of the predatory mite Typhlodromalus aripo and the entomopathogenic fungus Neozygites tanajoae on the supp...

There is an increasing awareness that vegetation diversity can affect herbi-vore and natural enemy abundance and that plants can play a major rolein directly manipulating natural enemy abundance for protection againstherbivore attacks. Using data from cassava fields, we aimed at (i) testingthe ca...

Interspecific predation and cannibalism are common types of interaction in phytoseiid predator guilds, but the extent and nature of these interactions have not been determined yet in phytoseiid guilds composed of African native and neotropical exotic phytoseiid predators found in cassava habitat ...

Predators face the challenge of accessing prey that live in sheltered habitats. The coconut mite Aceriaguerreronis Keifer (Acari: Eriophyidae) lives hidden beneath the perianth, which is appressed to the coconut fruit surface, where they feed on the meristematic tissue. Its natural enemy, the pre...

Under attack by herbivores, plants produce a blend of“herbivore-inducedplant volatiles (HIPV)”that help natural enemies of herbivores locating their prey,thereby helping plants to reduce damage from herbivory. The amount of HIPVemitted by plants increases with herbivore density and is positively ...

Populations of the phytoseiid predator Amblyseius(=Neoseiulus) idaeus (Denmark & Muma) From Northeastern Brazil, have been successfully introduced into Benin, West Africa, as part of a classical biological control campaign to control the exotic cassava green mite, Mononychellus tanajoa (Bondar). ...

The generalist predator Amblyseius swirskii is an efficient natural enemy of small insects and phytophagous mites, particularly thrips and spider mites. This phytoseiid species was considered for a long time as a subtropical species and Amblyseius rykei as a sub-Saharan African species. A recent ...

Predatory mites identified as Neoseiulus paspalivorus DeLeon (Phytoseiidae) have been considered as agents for classical biological control of the coconut mite, Aceria guerreronis Keifer (Eriophyidae), in Africa and elsewhere. Preliminary identification of geographically distinct populations as b...
