The coconut mite, Aceria guerreronis Keifer, is one of the main pests of the coconut tree (Cocos nucifera L.) worldwide. Its control is mainly based on the use of acaricides. However, due to the habitat of this pest mite, which is protected by fruit bracts that act as a physical barrier, chemical control is often inefficient. Thus, natural enemies have been studied as an alternative to acaricides. We evaluated the functional and numerical responses of Amblyseius aerialis (Muma) to increasing densities of A. guerreronis (40, 80, 160, 240 and 360) and additionally the oviposition rates of the phytoseiid A. aerialis over 11 days on different food sources: coconut pollen, A. guerreronis and a mix of pollen and A. guerreronis. Our results showed that Amblyseius aerialis showed a type III functional response, where prey consumption increasing as the density of A. guerreronis increased, with a maximum consumption of up to 175 prey per predator. All the prey densities allowed female oviposition. The number of eggs laid by A. aerialis increased with increasing prey density and stabilized between 240 and 360 A. guerreronis individuals, with an average oviposition of 1.7 eggs/female. Furthermore, our results showed that all the food sources (coconut pollen, A. guerreronis and a mix of pollen and A. guerreronis) supported oviposition. The mean oviposition was approximately 1.5 eggs/female on all the food sources. Our study suggests that A. aerialis can be effective in the biological control of A. guerreronis. However, further studies are needed to investigate whether A. aerialis can explore the habitat of A. guerreronis and if that prey can support the development of immature stages and the reproduction of A. aerialis.

Coconut Mite

Typhlodromus (Anthoseius) ornatus Denmark & Muma (Acari: Phytoseiidae) is one of the predatory mites associated with the coconut mite Aceria guerreronis (Acari: Eriophyidae), a serious coconut pest in Africa, Asia and America. Vegetable oils such as coconut oil have been shown to efficiently control A. guerreronis, however their side effects on predatory mites remain poorly investigated. Here, we evaluated the lethal and non-lethal effects of coconut oil on repellence and functional response of the predatory mite T. ornatus, a natural enemy of A. guerreronis. Based on LC50 estimates, coconut oil was over 6-fold less toxic to T. ornatusthan to its prey, A. guerreronis. Additional repellence and predation bioassays show that the coconut oil neither repels nor interferes in the functional response of T. ornatus preying upon A. guerreronis. According to our selectivity approach, the coconut oil is compatible with the predatory mite T. ornatus.

AbstractThe simultaneous infestation of a plant by several species of herbivores may affect the attractiveness of plants to the natural enemies of one of the herbivores. We studied the effect of coconut fruits infested by the pestsAceria guerreronisandSteneotarsonemus concavuscutum, which are generally found together under the coconut perianth. The predatory miteNeoseiulus barakiproduced lower numbers of offspring on fruits infested withS. concavuscutumand on fruits infested with both prey than on fruits withA. guerreronisonly. The predators were attracted by odours emanating from coconuts withA. guerreronis, but not by odours from coconuts withS. concavuscutum, even whenA. guerreroniswere present on the same fruit. FewerN. barakiwere recaptured on fruits with both prey or withS. concavuscutumthan on fruits with onlyA. guerreronis. Furthermore, the quality ofA. guerreronisfrom singly and multiply infested coconuts as food forN. barakidid not differ. Concluding, our results suggest thatN. barakidoes not perform well whenS. concavuscutumis present on the coconuts, and the control ofA. guerreronisbyN. barakimay be negatively affected by the presence ofS. concavuscutum.
