Acaricide-impaired functional predation response of the phytoseiid mite Neoseiulus baraki to the coconut mite Aceria guerreronis. Repositório Alice

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...

Effect of acaricides on Calepitrimerus vitis (Napela, 1905) (Acari: Eriophyidae) and on the production os vineyards. Repositório Alice
SIQUEIRA, P. R. E.; BOTTON, M.; BAYER SIQUEIRA, P. R.; PERES, G. S.; SOARES, L. da L..
The southernmost region of the state of Rio Grande do Sul, Brazil, has emerged as one of the major poles for fine grape production (Vitis vinifera) for wine processing. In this region, grapevine rust mite (Calepitrimerus vitis) is one of the major pests for the culture; however, information is lacking about production losses caused by this species and acaricides for its control. In this paper, the acaricide effect of azadarachtin, boron + nitrogen on orange peel oil, sulfur and spirodiclofen on C. vitis on Merlot cultivar commercial grapevine was evaluated and production losses caused by the presence of the mite were estimated. The experiment was conducted during the 2012/2013 and 2013/2014 growing seasons, comparing the infestation levels of C. vitis and...
