Biological control of Frankliniella occidentalis
In Spain, experiments were carried out to compare the predatory activity of phytoseiid mites on different developmental stages of Frankliniella occidentalis (EPPO A2 pest). Compared were Amblyseius barkeri, A. californicus, A. andersoni, Euseius stipulatus and Typhlodromus occidentalis.
A. andersoni had the highest predatory effect against the Western flower thrips, but also A. bakeri and A. californicus showed promising results. The authors suggest that A. andersoni and A. bakeri are promising biocontrol agents against F. occidentalis.
