Not Led by the Nose: Volatiles from Undamaged Eucalyptus Hosts Do Not Influence Psyllid Orientation

“…Hence, it is possible that sensory modalities other than olfaction may play a more important role in the location of juvenile leaves by C. eucalypti . In addition, Eucalyptus -feeding psyllids, including the four species used in this study, have been shown to exploit visual cues such as leaf color and size to locate host leaves of the preferred age [15,16,17]. As a result, compelling evidence suggests that vision plays a predominant role in host location by these psyllids.…”

“…Olfactory, mechanical and/or gustatory cues perceived during selection determine whether the insect “settles” and initiates sustained feeding and oviposition (acceptance) or whether it re-engages in host finding (rejection). Visual cues such as leaf shape, size and color or even light polarization have been identified as important factors in host finding by some psyllids [15,16,17,18,19,20]. The significance of plant-specific and presumably more reliable olfactory cues provided by HPVs remains uncertain [21,22].…”

‘Same same but different’ Exploring evolutionary and ecological causes of eye diversification in bumblebees

“…How do bumblebee visual traits compare to those of species in other insect orders? Using previous literature, we calculated the variability of visual traits (CV and HR) in a genus of damselflies (Scales and Butler, 2016) and a family of psyllids (Farnier et al, 2015). We found that bumblebee visual traits were approximately equally variable ( Table 1 ) as in psyllids ( Table S3a , only HR and not CV is relevant given the small number of studied psyllids) and in damselflies ( Table S3b ) .…”

“…This is likely because sensory traits are often difficult to measure, and the available data on how they relate to an animal’s ecology are scarce. However, in recent years, sensory biologists have shown a growing interest for comparative approaches that quantify and integrate sensory properties into a phylogenetic framework (for example in arthropod eyes: Farnier et al, 2015; Feller et al, 2020; Keesey et al, 2020; Scales and Butler, 2016; Streinzer and Spaethe, 2014a). Comparative studies not only are valuable to understand the evolution of sensory systems (Chittka and Briscoe, 2001; Dangles et al, 2009), but also open the possibility to integrate sensory properties in trait-based analyses in ecology and conservation biology.…”

A “Walker” Tool to PlaceDiaphorina citri(Hemiptera: Liviidae) Adults at Predetermined Sites for Bioassays of Behavior in Citrus (Sapindales: Rutaceae) Trees

“…In addition, because large supplies of D. citri adults of specific sex, mating status, and age require considerable labor and time to separate from a rearing colony (Paris et al 2013), there is interest in reducing the proportion of escapees in mating behavior and other bioassays where test psyllids of such specifications are needed. Like many other jumping plant lice (e.g., White 1970;Nissinen 2007;Nissinen et al 2008;Farnier et al 2015), D. citri exhibits positive phototropic behavior (Sétamou et al 2011;Anco & Gottwald 2015;Paris et al 2015). To coopt this behavior, we developed a walker tool, a darkened cone through which a psyllid may walk voluntarily towards a lighted opening, exit onto a predetermined bioassay site, and remain until testing.…”
