“…The rearing procedures were adapted from Pacheco et al (2021) and adults were occasionally supplemented with the aphid Schizaphis graminum (Rondani) (Hemiptera: Aphididae) from a rearing colony kept in the laboratory. Rearing of C. capitata and the parasitoid D. longicaudata followed the methods described by Fernandes et al (2019) and Alvarenga et al (2005 ), respectively.…”

“…The number of fruit flies in each treatment was established in preliminary tests, which established that these numbers were more than enough for daily consumption by an earwig. All treatments with fruit fly larvae contained a small amount of artificial diet (~0.01 g) (Fernandes et al, 2019) to keep them alive for 24 h. The earwigs did not feed on the fruit fly artificial diet and consumed only fruit fly larvae. The number of fruit fly prey consumed by earwigs was recorded every 24 h for 10 days.…”

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.

“…Tetrastichus giffardianus Silvestri is a gregarious koinobiont endoparasitoid that oviposits in the larvae of several species of tephritids, including pest species (Fernandes et al ., 2019 a ). This parasitoid was introduced into Hawaii in 1912 from West Africa for biological control of the Mediterranean fly Ceratitis capitata (Wiedemann) and quickly became established throughout the Hawaiian Islands (Purcell et al ., 1996).…”

Tetrastichus giffardianus is a gregarious koinobiont endoparasitoid of tephritids, including Ceratitis capitata, which is one of the most important fruit pests worldwide. The objective of this study was to evaluate the effect of constant temperatures on the biology and development of the egg-adult period of T. giffardianus in larvae/pupae of C. capitata to construct a fertility life table. The study was carried out in climatic chambers at constant temperatures of 15, 20, 25, 30, and 35 ± 1°C, 70 ± 10% relative humidity and a photophase of 12 h. Complete egg and larval development occurred only at temperatures of 20, 25, and 30°C. The mean longevity of males and females was inversely proportional to temperature. The time of development of the pre-imaginal period was influenced by temperature and ranged from 41 days at 20°C to 11 days at 25°C. The best T. giffardianus performance occurred at 25°C when the intrinsic rate of increase was 0.21, the mean generation time was 20.43 days, the time required to double the population was 3.33 days, and the finite rate of population increase (λ) was 1.23. The results of this study provided information for the establishment of mass rearing and an evaluation of the adaptability of T. giffardianus to different environments, which is necessary for the use of this parasitoid in the biological control of tephritid pests, particularly C. capitata.
