“…Data from surveys conducted before and after the introduction of T. aripo in Malawi showed negative impact of E. fustis and I. degenerans on M. tanajoa densities (Zannou 2003). Moreover, Onzo et al (2003aOnzo et al ( , 2005 reported that E. fustis has a negative impact on M. tanajoa populations in Se`, south-eastern Benin, and on potted cassava plants in the screenhouse. Indeed, the indigenous phytoseiids, E. fustis and I. degenerans, as well as the introduced T. aripo may have a complementary negative impact on M. tanajoa populations.…”

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 in southern Africa. We determined in laboratory experiments the level of cannibalism and interspecific predation among the three phytoseiid mite species Euseius fustis, Iphiseius degenerans, and Typhlodromalus aripo in the absence of food and in the presence of limited or abundant quantities of two food types--Mononychellus tanajoa and maize pollen--commonly found on cassava in Africa. When confined without food, only two T. aripo females laid each two eggs within 5 days, and this species survived longer than I. degenerans and E. fustis. In the presence of con- or hetero-specific larvae or protonymphs, the three species fed more on the former than on the latter, and more on hetero-specifics than on con-specifics. Oviposition rates of the three species did not exceed 0.7 egg/female/day on con- and hetero-specific immatures. Typhlodromalus aripo and E. fustis survived longer on con-specific and hetero-specific larvae and on hetero-specific protonymphs than in the absence of any food, while T. aripo survived longer than the two other species on the same diets. Provision of limited quantity of food decreased interspecific predation rate by I. degenerans and T. aripo, but not by E. fustis, and increased oviposition rate and longevity of all three species. Provision of abundant food, however, eliminated cannibalism by all three species and further reduced interspecific predation rates, but their oviposition and longevity remained relatively unchanged compared with limited food provision. Potential consequences of cannibalism and interspecific predation among phytoseiid mites on cassava for the biological control of M. tanajoa are discussed.

“…IGP may be avoided if the contestants inhabit different plant strata (Zannou et al 2007), by placing their eggs in domatia (see below) or by the availability of other nutrients (e.g. pollen, Onzo et al 2005). Plantprotection chemicals also affect the outcome.…”

“…The availability of alternative foods on coconut palms such as coconut pollen, tarsonemid mites and Rhizopus may help to sustain the populations of both predatory mites when A. guerreronis is scarce (Onzo et al 2005;Sabelis and van Rijn 2005). The rather high intrinsic rate of increase of P. bickleyi reached with Rhizopus could be highly favourable for mass-rearing and augmentative release purposes.…”

Life history of the predatory mites Neoseiulus paspalivorus and Proctolaelaps bickleyi, candidates for biological control of Aceria guerreronis

The eriophyoid mite Aceria guerreronis Keifer (Eriophyidae), commonly called the coconut mite, is a key pest of coconut fruits. Surveys conducted on coconut palms in Brazil revealed the predatory mites Neoseiulus paspalivorus DeLeon (Phytoseiidae) and Proctolaelaps bickleyi Bram (Ascidae) as the most commonly associated natural enemies of A. guerreronis on coconut fruits. However, virtually nothing is known about the life history of these two predators. We conducted laboratory experiments at 25 +/- 0.1 degrees C, 70-90% RH and 12:12 h L:D photoperiod to determine the life history characteristics of the two predatory mites when feeding on A. guerreronis and other potential food sources present on coconut fruits such as Steneotarsonemus furcatus DeLeon (Tarsonemidae), coconut pollen and the fungus Rhizopus cf. stolonifer Lind (Mucoraceae). In addition, the two-spotted spider mite Tetranychus urticae Koch (Tetranychidae) was tested for its suitability as prey. Both predators, N. paspalivorus and P. bickleyi, thrived on A. guerreronis as primary food source resulting in shorter developmental time (5.6 and 4.4 days, respectively), higher oviposition rate (1.7 and 7.0 eggs/female/day, respectively) and higher intrinsic rate of increase (0.232 and 0.489 per female/day, respectively) than on any other diet but were unable to develop or lay eggs when fed T. urticae. Coconut pollen and S. furcatus were adequate alternative food sources for N. paspalivorus and Rhizopus for P. bickleyi. We discuss the relevance of our findings for natural and biological control of the coconut mite A. guerreronis.
