“…As shown previously, pollen is an excellent food source for predatory mites (van Rijn and Tanigoshi 1999; Nomikou et al 2003;Gnanvossou et al 2005;Rodríguez-Cruz et al 2013). Here, A. herbicolus reached the highest oviposition rates when the mites were feeding on pollen (honeybee, Typha sp.…”

“…Chilli pepper flowers face the leaves under the flowers, allowing their pollen to rain down on the leaves. Given that pollen is a good food source for predatory mites (van Rijn and Tanigoshi 1999;Nomikou et al 2003;Gnanvossou et al 2005), the production of excess of pollen could be a trait that evolved as an indirect plant defence (Sabelis et al 1999(Sabelis et al , 2011.…”

Alternative food promotes broad mite control on chilli pepper plants

et al. 2015

Many omnivorous arthropods are important natural enemies because they can feed on plantprovided pollen and several prey species, and thus persist in crops even in the absence of the target pest. Hence, populations of these predators can be established in a crop by providing alternative food, thus increasing biological control. We investigated how alternative food affects broad mite (Polyphagotarsonemus latus) control on chilli pepper plants by predatory mites. The predatory mite Amblyseius herbicolus had high oviposition and population growth rates when fed with cattail pollen, chilli pepper pollen and bee-collected pollen, and a low rate on the alternative prey Tetranychus urticae. Supplementing pepper plants with pollen resulted in better control of broad mite populations. Release of A. herbicolus on young plants with weekly addition of honeybee pollen until plants produce flowers seems a viable strategy to sustain populations of this predator, thus protecting young, vulnerable plants from broad mite infestations.

“…For T. aripo, a generalist predator that feeds on a variety of food (Gnanvossou et al 2005), its generally low feeding rate (Gnanvossou et al 2005;Magalha˜es et al 2003) and its preference for maize pollen and M. tanajoa may have led to lower interspecific predation and cannibalism rate. Iphiseius degenerans and E. fustis are also generalist predators that feed on M. tanajoa but prefer pollens (BruceOliver et al 1996;Nwilene and Nachman 1996;Van Rijn and Tanigoshi 1999).…”

Cannibalism and Interspecific Predation in a Phytoseiid Predator Guild from Cassava Fields in Africa: Evidence from the Laboratory

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.

“…During encounters with preys, insect predators also use hairs on the leaves for support (MacRae and Croft, 1997) and hairy cassava tips found in the present study may provide suitable habitats for T. aripo to adequately exploit CGM prey. It has been reported that T. aripo survives, develops and oviposits on pollen diet (Gnanvossou et al, 2005), and probably the hairy apices of some cassava varieties contribute to better trapping of pollen grains (Roda et al, 2003) from wild plants. This provide alternative food sources with commensurate effects on survival, longevity and fecundity of T. aripo.…”
