Acaricide-impaired functional predation response of the phytoseiid mite Neoseiulus baraki to the coconut mite Aceria guerreronis. Repositório Alice
LIMA, D. B.; MELO, J. W. S.; GONDIM JÚNIOR, M. G. C.; GUEDES, R. N. C.; OLIVEIRA, J. E. de M.; PALLINI, A..
Acaricides may interfere with a myriad of interactions among arthropods, particularly predator?prey interactions. The coconut mite, Aceria guerreronis Keifer (Acari: Eriophyidae), and its phytoseiid predator, Neoseiulus baraki (Athias-Henriot) (Acari: Phytoseiidae), provide an opportunity to explore such interference because the former is a key coconut pest species that requires both predation and acaricide application for its management. The objective of the present study was to assess the effect of the acaricides abamectin, azadirachtin and fenpyroximate on the functional response of N. baraki to A. guerreronis densities. The following prey densities were tested: 5, 10, 20, 40 and 80 preys. The type of functional response and prey handling time (Th) were...

Estimated crop loss due to coconut mite and financial analysis of controlling the pest using the acaricide abamectin. Repositório Alice
REZENDE, D.; MELO, J. W. S.; OLIVEIRA, J. E. de M.; GONDIM JÚNIOR, M. G. C..
Reducing the losses caused by Aceria guerreronis Keifer has been an arduous task for farmers. However, there are no detailed studies on losses that simultaneously analyse correlated parameters, and very few studies that address the economic viability of chemical control, the main strategy for managing this pest. In this study the objectives were (1) to estimate the crop loss due to coconut mite and (2) to perform a financial analysis of acaricide application to control the pest. For this, the following parameters were evaluated: number and weight of fruits, liquid albumen volume, and market destination of plants with and without monthly abamectin spraying (three harvests). The costs involved in the chemical control of A. guerreronis were also quantified....

Population-level effects of abamectin, azadirachtin and fenpyroximate on the predatory mite Neoseiulus barak. Repositório Alice
LIMA, D. B.; MELO, J. W. S.; GONDIM JÚNIOR, M. G. C.; GUEDES, R. N. C.; OLIVEIRA, J. E. de M..
The coconut production system, in which the coconut mite Aceria guerreronis is considered a key pest, provides an interesting model for integration of biological and chemical control. In Brazil, the most promising biological control agent for the coconut mite is the phytoseiid predator Neoseiulus baraki. However, acaricides are widely used to control the coconut mite, although they frequently produce unsatisfactory results. In this study, we evaluated the simultaneous direct effect of dry residue contact and contaminated prey ingestion of the main acaricides used on coconut palms (i.e., abamectin, azadirachtin and fenpyroximate) on life-history traits of N. baraki and their offspring. These acaricides are registered, recommended and widely used against A....
