“…drosophilae and P. vindemmiae since their preimaginal development on this fly species was similar or shorter than when they parasitize other fly species (Romani et al 2008;Wang and Messing 2004;Le Lann et al 2014). Furthermore, P. vindemmiae daily offspring on D. suzukii is close to those reported by Pawson and Petersen (1990) and Zhao et al (2013) on Musca domestica L (Diptera: Muscidae) and…”

The invasive pest Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) causes serious economic damage in several soft fruit crops. This study aimed (1) to identify naturally occurring parasitoids and predators of this pest in North East Spain and (2) to get preliminary data on their potential as pest biological control agents. Two parasitoid species were found spontaneously parasitizing D. suzukii: Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) and Trichopria cf. drosophilae Perkins (Hymenoptera: Diapriidae). Both species were found repeatedly through the survey period and successfully reproduced in the laboratory on D. suzukii pupae. In addition, both species strongly reduced adult emergence of D. suzukii from infested fruits. Regarding predators, Orius laevigatus (Fieber) (Hemiptera: Antochoridae) were able to feed on D. suzukii eggs but not on larvae whereas the soil predator Labidura riparia Pallas (Dermaptera: Labiduridae) consumed D. suzukii larvae and pupae and was effective in reducing pest populations in laboratory tests.

“…Egg parasitoids are well studied because they are important in biological control programmes and kill the host before it is able to inflict damage on the plant on which the eggs were laid (Godfray, 1994). Evidence suggests that pupal parasitoids prefer to oviposit on higher quality hosts (Ueno, 1997;Zhao et al, 2013). Evidence suggests that pupal parasitoids prefer to oviposit on higher quality hosts (Ueno, 1997;Zhao et al, 2013).…”

International audience1. The optimisation theory predicts that insect mothers should oviposit on resources on which they attain the highest exclusive fitness. The development of parasitoid wasps is dependent on limited host resources that are often not much larger than the adult parasitoid.2. In the present study preference and development in three congeneric species of secondary hyperparasitoids attacking cocoons of two congeneric primary parasitoids that differ significantly in size were compared. Gelis agilis (Fabricius) and G. acarorum (L.) are wingless hyperparasitoids that forage in grassy habitats, whereas G. areator (Panzer) is fully winged and forages higher in the canopy of forbs.3. The three species were reared on cocoons containing pupae of a small gregarious endoparasitoid, Cotesia glomerata (L.), and a larger solitary species, C. rubecula (Marshall), both of which develop in the caterpillars of pierid butterflies.4. Adult mass was correlated with initial cocoon mass in all three species, whereas development time was unaffected. Wasps were larger when developing in C. rubecula. However, for a given host mass, wasps were larger when developing on the smaller host, C. glomerata. This suggests that there is a physiological limit to hyperparasitoid size that was exceeded when C. rubecula served as host.5. All three hyperparasitoids strongly preferred to attack cocoons of the larger species, C. rubecula, often avoiding cocoons of C. glomerata entirely. 6. Preference and performance are correlated in the three Gelis species. However, owing to variation in the distribution and thus abundance of their hosts, it is argued that cumulative fitness may be still higher in the smaller host species

“…These results suggest that host suitability is higher in younger host pupae. The majority of available literatures show similar results [14,[29][30][31][32]; a decrease of host suitability with pupal age appears to be the general rule.…”
