“…As predicted, E. annulipes females were more voracious than males, as they consumed larger numbers of fruit fly larvae or pupae, in agreement with the aggressive behaviour of females previously reported for earwigs (Moral, Demetrio, et al, 2017; Nunes et al, 2018; Oliveira, Alves, et al, 2019). Earwig females likely require more food because they are larger than males and require more energy to produce eggs and provide maternal care (Rankin et al, 1995).…”

“…Similarly to other species of earwigs (Oliveira, Alves, et al, 2019; Tangkawanit et al, 2021), our study showed that E. annulipes preyed more on larvae than on pupae. Other studies have reported that E. annulipes prefers to consume larvae over pupae of a lepidopteran prey (Nunes et al, 2018; Nunes, Dantas, et al, 2019; Nunes, Paulo, et al, 2020). The higher predation capacity of earwigs for insect larvae is likely related to the hardness of the tegument, which is harder in the pupal than in the larval stage, acting as protection against natural enemies (Kalinoski & DeLong, 2015).…”

The earwig Euborellia annulipes (Lucas) (Dermaptera: Anisolabididae), a generalist predator, has been observed in fruits infested with fruit fly larvae, which are frequently parasitized by parasitoid wasps. Neither the capacity of earwigs to predate on fruit flies nor intraguild interactions between earwigs and fruit fly parasitoids have been investigated. Here, we studied in laboratory conditions the predation on the fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) by the earwig E. annulipes, and whether parasitism of fruit fly larvae by the parasitoid wasp Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) influences predation by the earwig. We evaluated the predation capacity, functional response and prey preference of E. annulipes for parasitized and non‐parasitized fruit fly larvae in choice and no‐choice tests. We found that earwigs prey on second‐ and third‐instar larvae and pupae of C. capitata and consumed larger numbers of second‐instar larvae, followed by third‐instar larvae and pupae. Females prey on larger numbers of fruit flies than did males, regardless of the prey developmental stage, but both sexes exhibited a type II functional response. Interestingly, males killed but did not consume fruit fly larvae more than did females. In no‐choice tests, earwig females consumed equal numbers of parasitized and non‐parasitized fruit fly larvae. However, in choice tests, the females avoided feeding on parasitized larvae. Subsequent tests with hexane‐washed parasitized and non‐parasitized larvae showed that putative chemical markings left on fruit flies by parasitoids did not drive the earwig preference towards non‐parasitized larvae. These findings suggest that E. annulipes is a potential biological control agent for C. capitata, and that, because the earwig avoids consuming larvae parasitized by D. longicaudata, a combination of the two natural enemies could have an additive effect on pest mortality.

“…Doru luteipes has been recognized as a generalist predator of lepidopteran eggs and larvae in maize, soybean, sugarcane, and B. oleracea crops [47][48][49]58,59]. Natural occurrence and predation of P. xylostella by the earwig species Euborellia annulipes (Dermaptera: Anisolabididae) has been reported in kale crops and intercrops with Lobularia maritima (Brassicaceae) [60]. This lack of preference for P. xylostella could be due to the origin of the earwigs used in this study, as they were from maize and sugarcane plantations, where S. frugiperda is a big part of their diet.…”

Plant-associated microbes may induce plant defenses against herbivores. Plants, in turn, can attract natural enemies, such as predators, using herbivore-induced plant volatiles. Intricate communication occurs between microorganisms, plants, and insects. Given that many aspects related to mechanisms involved in this symbiotic system remain unknown, we evaluated how beneficial soil-borne microorganisms can affect the interactions between plants, herbivores, and natural enemies. For this study, we established a multitrophic system composed of the predatory earwig Doru luteipes (Dermaptera: Forficulidae), arugula (Eruca sativa, Brassicaceae) as the host plant, Plutella xylostella (Lepidoptera: Plutellidae) larvae as a specialist herbivore, Spodoptera frugiperda (Lepidoptera: Noctuidae) larvae as a generalist herbivore, and Bacillus amyloliquefaciens as the plant growth-promoting rhizobacteria (PGPR), in a series of nocturnal olfactometry experiments. By assessing earwig preference towards herbivore-induced and PGPR-inoculated plants in different combinations, we showed that the interaction between rhizobacteria, plants, and herbivores can affect the predatory earwig’s behavior. Furthermore, we observed a synergistic effect in which earwigs were attracted by plants that presented as PGPR inoculated and herbivore damaged, for both specialist and generalist herbivores. Our findings help fill the important knowledge gap regarding multitrophic interactions and should provide useful guidelines for their application to agricultural fields.

“…Earwigs were found to be predators in cruciferous crops, such as cabbage in The Philippines (Basedow, 1993) and collard greens in Brazil (Ribeiro & Gontijo, 2017). The ringlegged earwig, Euborellia annulipes (Lucas) (Dermaptera: Anisolabididae), is considered to be one of the most cosmopolitan species (Kocarek et al, 2015) and, although it is omnivorous, some researchers have reported this insect as a predator of lepidopteran pests, such as Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) and P. xylostella (Silva et al, 2009;Moral et al, 2017;Nunes et al, 2018). However, there are few studies evaluating the predation behavior of E. annulipes and its effect on economically important insect pests.…”

The diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), is the main pest of brassica crops worldwide. The ringlegged earwig, Euborellia annulipes (Lucas) (Dermaptera: Anisolabididae), has been reported as a potential predator of lepidopteran larvae, including this pest, and may therefore be used for biological control. Knowledge about predator-prey interactions is important to establish pest management strategies. Therefore, the objective of this work was to evaluate the influence of the developmental stage (larva and pupa) and density of P. xylostella on the preference and functional response of E. annulipes adult females. We used choice and no-choice tests to evaluate the foraging behavior and preference of E. annulipes on DBM life stages and varied prey density to assess the type of functional response of the ringlegged earwig. Larvae were preferred over pupae, and the predator's functional response was type II for both prey stages. Our results report the potential of E. annulipes as a biocontrol agent of P. xylostella. Understanding their interactions may help in decision-making and optimization of integrated management strategies.
