“…During the nighttime, however, all colored models captured similar numbers of impressions, although a greater number of impressions were recorded during the night than during the day, implying that either densities of predators or their activity were greater during the night than during the day, and predaceous behavior was not influenced by prey color. Previously, studies showed that successful host searching and acceptance involved chemical cues from prey ( Yasuda 1997 , Xue et al 2018 ), herbivore-induced plant volatiles ( Drukker et al 2000 , Schuman and Baldwin 2016 ), or a combination of tactile, visual, olfactory (smell), and gustatory (taste) cues ( Halpin and Rowe 2016 , Duong et al 2017 , Manubay and Powell 2020 , Yamazaki et al 2020 ). Data also suggest that diurnal predators, especially birds, use visual cues to spot suitable prey ( Zvereva et al 2019 , Yamazaki et al 2020 ).…”

“…Arthropod predators are active in the ground, especially on the temperate forest floor ( Ferrante et al 2017 ). They use chemical, tactile, visual, and gustatory cues to search and locate prey ( Yasuda 1997 , Halpin and Rowe 2016 , Duong et al 2017 , Xue et al 2018 , Yamazaki et al 2020 ). Along with the color and color patterns, the ambient light availability, shape, and size of the insect also play a role in determining the visual perception of the predator ( Troscianko et al 2009 ).…”

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 in turfgrass. Little is known about whether the characteristics of clay models, such as color, shape, and size, influence arthropod interactions in turfgrass. To improve the utility of clay models in turfgrass, the influence of the color, shape, and size of clay models on arthropod interactions was studied by exposing clay models during daytime and nighttime in a turfgrass field. The results showed that arthropods interacted with clay models, and various types of impressions were recorded, including paired marks, scratches, cuts, and pricks. Although the color of the clay model had no significant effects on arthropod interactions during the night, significantly greater numbers of impressions were noticed on the blue and green models than on the yellow models during the daytime. The caterpillar-shaped models captured significantly greater densities of impressions than the beetle-shaped models. Additionally, the number of impressions significantly increased with an increase in the size of the model regardless of shape.

“…However, the role of CHCs in predator–prey interactions is comparatively understudied. Investigations into how predatory insects use CHCs to identify prey from nonprey items can provide insights into predation shaped outside of the lens of visual processes (Koedam et al, 2011; Rutledge et al, 2014; Xue et al, 2018).…”

Differential predation on species with intraspecific colour variation has been explored in various systems and is often implicated as the driving force behind colour polymorphism maintenance. Here, investigation done on whether predation contributes to the maintenance of extensive colour variation in the Neotropical tortoise beetle, Chelymorpha alternans (Chrysomelidae). Recorded predation rates on different colour pattern phenotypes by three common, generalist invertebrate predators, and identified potential chemical signals of unpalatability. Predaceious mantids (Orthoptera, Mantidae) consumed no beetles, regardless of phenotype, whereas the giant orb‐weaving spider (Trichonephila clavipes; Araneidae) consumed all three beetle phenotypes. The carton‐nest ant, Azteca chartifex (Formicidae), displayed differential predation; the rufipennis phenotype of C. alternans was sometimes consumed, the metallic phenotype was never consumed, and the veraguensis phenotype was consumed in the first three encounters and subsequently discarded, suggesting a learned avoidance behaviour. Using gas chromatography–mass spectrometry, it was determined that cuticular hydrocarbon profiles were similar between the metallic and militaris‐a phenotypes. The rufipennis phenotype showed pronounced differences and displayed the greatest among‐individual variation in elytral cuticular profiles. Between‐phenotype variation in chemical cues, and differences in how predators receive those cues, may mediate predator response, and play a role in maintaining colour variation in this species.

“…Nevertheless, this mechanistic knowledge of specialization is lacking in diverse assemblages of predatory insects (but see Rana, Dixon, & Jarošík, 2002;Xue, Wei, Huang, Li, & Yang, 2018 for species-specific examples), which despite their trophic footprint are rarely the focus of studies addressing dietary specialization (but see Hashimoto & Yamane, 2014;Kaspari, Powell, Lattke, & O'Donnell, 2011).…”

“…In such cases, specialization is often underpinned by sensory specialization (Stevens, 2013), including the combination of multiple senses to maximize foraging efficiency (Siemers et al, 2007; Vincent, Shine, & Brown, 2005). Nevertheless, this mechanistic knowledge of specialization is lacking in diverse assemblages of predatory insects (but see Rana, Dixon, & Jarošík, 2002; Xue, Wei, Huang, Li, & Yang, 2018 for species‐specific examples), which despite their trophic footprint are rarely the focus of studies addressing dietary specialization (but see Hashimoto & Yamane, 2014; Kaspari, Powell, Lattke, & O'Donnell, 2011).…”

1. Deciphering the mechanisms that underpin dietary specialization and niche partitioning is crucial to understanding the maintenance of biodiversity. New world army ants live in species-rich assemblages throughout the Neotropics and are voracious predators of other arthropods. They are therefore an important and potentially informative group for addressing how diverse predator assemblages partition available prey resources.2. New World army ants are largely specialist predators of other ants, with each species specializing on different ant genera. However, the mechanisms of prey choice are unknown. In this study, we addressed whether the army ant Eciton hamatum: (a) can detect potential prey odours, (b) can distinguish between odours of prey and non-prey and (c) can differentiate between different types of odours associated with its prey. 3.Using field experiments, we tested the response of army ants to the following four odour treatments: alarm odours, dead ants, live ants and nest material. Each treatment had a unique combination of odour sources and included some movement in two of the treatments (alarm and live ants). Odour treatments were tested for both prey and non-prey ants. These data were used to determine the degree to which E. hamatum are using specific prey stimuli to detect potential prey and direct their foraging. 4. Army ants responded strongly to odours derived from prey ants, which triggered both increased localized recruitment and slowed advancement of the raid as they targeted the odour source. Odours from non-prey ants were largely ignored.Additionally, the army ants had the strongest response to the nest material of their preferred prey, with progressively weaker responses across the live ant, dead ant and alarm odours treatments respectively.5. This study reveals that the detection of prey odours, and especially the most persistent odours related to the prey's nest, provides a mechanism for dietary specialization in army ants. If ubiquitous across the Neotropical army ants, then this olfaction-based ecological specialization may facilitate patterns of resource partitioning and coexistence in these diverse predator communities.
