Selecting an ornamental pepper banker plant for Amblyseius swirskii in floriculture crops
Arthropod-Plant Interactions 8 (1), 49-56
Abstract: Preference of phytoseiid mite, Amblyseius swirskii (Athias-Henriot) was assessed on four cultivars of ornamental pepper banker plant candidates; Red Missile (RM), Masquerade (MA), Explosive Ember (EE) and Black Pearl (BP) for potential control of pestiferous insects in floriculture. Significant differences in cultivar preference by A. swirskii was observed in choice experiments whether the test was pre- (with pollen) or during bloom. Overall, female mites laid more eggs when pollen was provided as a food source. The number of tuft domatia per cultivar leaf appeared to positively influence host preference in the choice plant tests pre-bloom. In addition, cultivar RM had the highest mean number ± SEM of tuft domatia per leaf (5.1 ± 0.3) and motiles per plant (4.0 ± 1.2), followed by MA, EE and BP. In choice tests on blooming plants, A. swirskii showed preference for both cultivars RM and MA compared to EE. These experiments indicated that the number of tuft domatia and availability of pollen can influence the host preference of A. swirskii for an ornamental pepper banker plant cultivar. Results from this study will help growers, researchers, educators and extension personnel in understanding the plant phenology promoting adoption of suitable banker plants for managing greenhouse and landscape insect pests.
