“…As in other studies, we found that D. suzukii were attracted to red, black, and yellow targets 25,26,29,56,60 . However, the attraction to single color targets was correlated with reflectance at short wavelengths (blue [470 nm] and green [560 nm]), rather than the overall color that humans perceive.…”

Drosophila suzukii Matsumura (Diptera: Drosophilidae) is a significant invasive pest in soft-skin fruits and berries in Asia, Europe, and North and South America. Many herbivorous insects use multiple cues for host selection, particularly olfactory and visual stimuli. The visual system of closely-related Drosophila melanogaster is well-documented, expressing strong sensitivity to short-wavelength colors (ultraviolet to green) and only limited sensitivity to long-wavelength colors (red to infrared). Our results suggest that D. suzukii have limited ability to distinguish red consistent with visual sensitivity range within the melanogaster subgroup. We propose that color contrast rather than color appearance may be of greater importance in orientation and attraction. We propose that differences in reflectance between light wavelengths important for color opponency are key to color discrimination to provide color contrast between foreground and background, as occurs between fruit and foliage, during host-finding.

“…For example, Chrysoperla carnea (Stephens) was in the laboratory a predator of SWD [ 20 , 24 ], but this predation was never confirmed in the field [ 22 , 31 ]. Also, the laboratory predatory activities of the Carabidae Pterostichus mutus (Say) and Bembidion quadrimaculatum (LeConte) and the Miridae Dicyphus hesperus Knight against SWD were not confirmed in the field [ 13 , 14 ]. Field predation of SWD by Formicidae was previously suggested, as ants were observed not only digging and carrying SWD pupae, but also preying on SWD pupae and larvae in dropped blueberries [ 25 , 26 ].…”

“…Despite some inconsistent laboratory vs. field data for SWD predation [ 13 , 14 , 16 , 23 ], other studies have shown that Chrysopids are promising predators to be used in the control of other insect pests: Chrysoperla spp. larvae might be used to control Tuta absoluta (Meyrick) (tomato pinworm) [ 39 ], Frankliniella occidentalis Pergande (western flower thrips) [ 40 ], Melanaphis sacchari (Zehntner) (sugarcane aphid) [ 41 ] or Glycaspis brimblecombei Moore (eucalyptus aphid) [ 42 ].…”

DNA screening of Drosophila suzukii predators in berry field orchards shows new predatory taxonomical groups

et al. 2021

Drosophila suzukii (spotted wing drosophila, SWD) is a pandemic quarantine pest that attacks mostly red fruits. The high number of life cycles per year, its ability to rapidly invade and spread across new habitats, and highly polyphagous nature, makes this a particularly aggressive invasive species, for which efficient control methods are currently lacking. The use of native natural predators is particularly promising to anchor sustainable and efficient measures to control SWD. While several field studies have suggested the presence of potential predatory species in infested orchards, only a few confirmed the presence of SWD DNA in predators’ gut content. Here, we use a DNA-based approach to identify SWD predators among the arthropod diversity in South Europe, by examining the gut content of potential predator specimens collected in SWD-infested berry fields in North Portugal. These specimens were morphologically identified to the family/order, and their gut content was screened for the presence of SWD DNA using PCR. New SWD predatory taxonomical groups were identified, as Opiliones and Hemerobiidae, in addition to known SWD predators, such as Hemerobiidae, Chrysopidae, Miridae, Carabidae, Formicidae and Araneae. Additionally, the presence of a spider family, Uloboridae, in the orchards was recorded for the first time, posing this family as another SWD-candidate predator. This study sets important bases to further investigate the potential large-scale use of some of these confirmed predator taxa for SWD control in South Europe.

“…Do crops have different levels of risk relative to the abundance of the most preferred oviposition sites? In Central Florida, D. suzukii is not a major pest, despite it's prevalence in the surrounding area where it is consistently detected in monitoring traps (Dean et al, 2012;Renkema et al, 2018). Meanwhile, in Northern Spain, strawberry is one the primary reproductive hosts reported for D. suzukii (Arnó et al, 2016).…”

Among insects, female oviposition preferences are critical to understanding the evolutionary dynamics between herbivores and hosts. Previous studies have shown Drosophila resource use has a strong genetic basis, although there is evidence that preferences are adaptable given isolation from ancestral hosts. Given the high degree of adaptability and behavioral plasticity of invasive species, we were interested in the mechanisms affecting host preferences of the invasive fruit fly, Drosophila suzukii, which in recent years has developed a nearly global range infesting small fruit crops. We studied the diet hierarchies of D. suzukii using a combination of laboratory and field assays designed to assess how female oviposition host choice differs given the availability of, and experience with, different fruit and non-fruit hosts. We found that host preferences did not shift over time and flies reared on two differential isolated diets up to F5 behaved and performed similarly regardless of diet lineage. Rather, female host choice appeared guided by a fixed hierarchical system of host preferences. Raspberry was more preferred to mushroom, which was more preferred to goose manure. However, if preferred resources were absent, the use of less-preferred resources was compensatory. We suggest that among niche specialists, such as D. suzukii, these hierarchies may support a bet-hedging strategy, rather than multiple-niche polymorphism, allowing for niche separation during periods of increased competition, while maintaining more diverse, ancestral feeding behaviors when preferred resources are scarce.
