Influence of the Color, Shape, and Size of the Clay Model on Arthropod Interactions in Turfgrass

Abstract: Many predatory arthropods occur naturally in turfgrass, and they provide adequate control of lepidopteran pests, such as fall armyworm, Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae), and black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae). Recording predation is challenging under field conditions because predators rarely leave any evidence. Clay models were successfully employed for studying predation, and this technique is underutilized … Show more

“…One mechanism for this phenomenon is that the perception and visibility of prey can change in complex vegetation with variable light availability (Théry & Gomez, 2010; Cheng et al, 2018). However, daytime predation of green and blue clay caterpillars was highest in less complex perennial systems like turfgrass despite their similarities to the color of the background vegetation (Khan & Joseph, 2021b).…”

“…17% on average) and the proportion that was attacked was statistically indistinguishable from brown and gray. Perhaps this should not have been surprising though as white clay caterpillars in sparse temperate forests and turfgrass systems are rarely attacked due to their reduced detectability in high light environments (Zvereva et al, 2019; Khan & Joseph, 2021b). Brown and gray caterpillars were attacked the least (ca.…”
