Effects of the entomopathogenic fungus Neozygites tanajoae and the predatory mite Typhlodromalus aripo on cassava green mite densities: screenhouse experiments

BioControl, 2013
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 suppression of M. tanajoa.

Attraction of the predatory mites Typhlodromalus manihoti and Typhlodromalus aripo to cassava plants infested by cassava green mite

Entomologia Experimentalis et Applicata, 2001
AbstractThe attraction of the predatory mites, Typhlodromalus manihoti and Typhlodromalus aripo, to the host plant‐spider mite complex, Manihot esculenta–Mononychellus tanajoa, was investigated with a Y‐tube olfactometer. Factors examined included predator starvation period, several combinations of cassava leaf biomass and initial M.

Crop Protection, 2002
Abstract An experiment to control the cassava green spider mite (CGM) Mononychellus tanajoa Bondar, an exotic pest of cassava, using an exotic predator Typhlodromalus aripo in cassava fields in the transition forest in Nigeria revealed a significant effect on the severity of cassava diseases. High population densities of T.

BEYOND FIELD SUCCESS: INSIGHTS INTO FUNCTIONAL AND NUMERICAL RESPONSE OF THE PREDATORY MITE TYPHLODROMALUS ARIPO AND THE ROLE OF CASSAVA EXUDATE IN PREDATORY PERFORMANCE

International Journal of Advanced Research
The predatory mite Typhlodromalusaripo is a key natural enemy of cassava green mite (Mononychellustanajoa) on cassava in Sub-Saharan Africa, yet its functional and numerical responses remain poorly understood.

Aspects of the Biology and Rate of Consumption of Neoseiulus Cucumeris Y Typhlodromalus Aripo (Acari: Phytoseiidae) on the Host Thrips Palmi Karny (Thysanopatera: Thripidae)

Revista Colombiana de Entomología, 2002
Thrips palmi Karny is an important pest of several crops, especially vegetables. The predatory mite Neoseiulus cucumeris has been successfully used in the control of various thrips species. The predatory mite T. aripo also has shown considerable capacity

Prey-Related Odor Preference of the Predatory Mites Typhlodromalus Manihoti and Typhlodromalus Aripo (Acari: Phytoseiidae)

Experimental & Applied Acarology, 2004
Typhlodromalus manihoti and Typhlodromalus aripo are exotic predators of the cassava green mite Mononychellus tanajoa in Africa. In an earlier paper, we showed that the two predators were attracted to odors from M. tanajoa-infested cassava leaves. In addition to the key prey species, M.

Effects of prey mite species on life history of the phytoseiid predators Typhlodromalus manihoti and Typhlodromalus aripo

Experimental & Applied Acarology, 2004
The effects of prey mite suitability on several demographic characteristics of phytoseiid predators and the relationship of these effects to the potential of phytoseiid predators to control herbivorous mite populations are well documented. Evidence has also accumulated in the last 20 years demonstrating that phytoseiid predators utilize herbivorous ...

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

Experimental & Applied Acarology, 2004
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.

Mix‐planting pubescent and glabrous cassava affects abundance of Typhlodromalus aripo and its prey mite Mononychellus tanajoa

Journal of Applied Entomology, 2014
AbstractThere is an increasing awareness that vegetation diversity can affect herbivore and natural enemy abundance and that plants can play a major role in directly manipulating natural enemy abundance for protection against herbivore attacks. Using data from cassava fields, we aimed at (i) testing the capacity of the predatory mite Typhlodromalus ...

Infochemical-Mediated Niche Use by the Predatory Mites Typhlodromalus manihoti and T. aripo (Acari: Phytoseiidae)

Journal of Insect Behavior, 2003
In Africa, Typhlodromalus manihoti and T. aripo, two introduced predators of the cassava green mite Mononychellus tanajoa, occupy different parts of cassava foliage. In the present study, niche use by these two predators, as mediated by prey-induced infochemicals, was investigated.
