“…Our work brings new information on the development of this parasitoid species in different host species and the way that the host species can affect some developmental traits of the parasitoid. Previous studies have reported parasitism rates for A. ervi as 74% in M. euphorbiae (Sidney et al 2010), 16.9% or 4.1% in M. persicae (Kavallieratos et al 2004, Gavkare et al 2014, 14.3% or no parasitism in R. padi (Rakhshani et al 2008, Stilmant et al 2008. These results differ from our findings in the present study, as we found parasitism rates of 2%, 19.8%, and 4% in M. euphorbiae, M. persicae, and R. padi, respectively.…”

“…Aphids are an important pest group throughout the world. Because of the damage they cause to vegetable, fruit, and grain crops, a few species stand out as particularly important: Macrosiphum euphorbiae Thomas, Myzus persicae Sulzer, Rhopalosiphum padi Linnaeus and Rhopalosiphum maidis Fitch (Hemiptera: Aphididae) (Blackman & Eastop 2007, Gavkare et al 2014. The main damage they cause is due to extraction of sap and fungal proliferation due to honeydew, but above all, they are vectors of a number of viral diseases (Boquel et al 2014, Xiao et al 2015.…”

“…Previous studies have approached this subject of host suitability and selection of parasitoids in different species and stages of aphids (Rakhshani et al 2004, Tomanovick et al 2009, Sídney et al 2010, Silva et al 2011, Monje et al 1999. Among the principal biological parameters measuring host suitability are rates of parasitism, survival to the adult stage, sex-ratio, immature developmental times and offspring size (Sidney et al 2010, Gavkare et al 2014, Gavkare et al 2013, Stilmant et al 2008. For the specific case of A. ervi and A. abdominalis, some of these parameters have been previously studied using some aphid hosts (Table 1).…”

“…For example, for A. ervi, Sidney et al (2010) studied developmental parameters using the host M. euphorbiae. Percentage of parasitism has been assessed on M. persicae (Gavkare et al 2014) and R. padi (Stilmant et al 2008). However, important parameters such as mean number of parasitized hosts, sex-ratio and offspring size have not still been assessed for M. persicae and R. padi (Table 1).…”

Parasitism rates and parasitoid development can be influenced by the species and developmental stage of the host, both of these factors can influence parasitoid performance and fitness. In this study, parasitism rates and developmental parameters were assessed for two widely distributed and commercially available species of aphid parasitoid: Aphidius ervi (Hymenoptera: Braconidae) and Aphelinus abdominalis (Hymenoptera: Aphelinidae). In a first bioassay, parasitism rates and parasitoid development were investigated in different host species. The wasp A. ervi was tested on Macrosiphum euphorbiae, Rhopalosiphum padi, and Myzus persicae (Hemiptera: Aphididae) and A. abdominalis was tested on M. persicae, R. padi, and Rhopalosiphum maidis (Hemiptera: Aphididae). The results indicated that A. ervi had a greater percentage of emergence, higher percentage of parasitized aphids, longer developmental time, and higher proportion of females in M. persicae than in the other hosts. A. abdominalis had a greater percentage of emergence, larger progeny, and shorter developmental time in R. padi than in the other hosts. A second bioassay evaluated the preference of the parasitoids for different instars of their respective optimum host aphids in terms of parasitism and development, as determined in the first bioassay. The results showed that A. ervi produced a greater number of mummies in the fourth instar and in adults of M. persicae. In contrast, A. abdominalis preferred the first instar of R. padi. In conclusion, our results indicate that both parasitoid species exhibit different parasitism parameters depending upon the host species and the host stage. This suggests that these parasitoid species could be potentially complementary on multiple or combined releases of biological control programs. 348 M.C. Velasco-Hernández et al.

“…The natural enemies used in the study were the predatory Harlequin ladybeetle Harmonia axyridis (Coleoptera: Coccinellidae) and the two parasitoid species Aphidius matricariae and Aphidius ervi (Hymenoptera: Aphidinae). These two parasitoids parasitize M. persicae on sweet pepper crops in greenhouses (Gavkare et al 2014) and the ladybeetle H. axyridis is often used to control M. persicae populations (De Clercq et al 2003).…”

Microbial endosymbionts alter the phenotype of their host which may have cascading effects at both population and community levels. However, we currently lack information on whether the effects of viruses on both host phenotypic traits and host population demography can modify interactions with upper trophic levels. To fill this gap, we investigated whether a prevalent densovirus infecting the aphid Myzus persicae (i.e. MpDNV) can modify trophic interactions between host aphids and their natural enemies (i.e. predators and parasitoids) by influencing aphid phenotypic traits (i.e. body mass and defensive behaviours), population demography (i.e. density and age‐structure) and susceptibility towards both predation and parasitism. We found that the virus decreased aphid body mass but did not influence their behavioural defences. At the population level, the virus had a minor effect on aphid adult mortality whereas it strongly reduced the density of nymphs and influenced the stage structure of aphid populations. In addition, the virus enhanced the susceptibility of aphids to parasitism regardless of the parasitoid species. Predation rate on adult aphids was not influenced by the virus but ladybeetle predators strongly decreased the number of aphid nymphs, especially for uninfected ones compared to infected ones. As a result, the virus decreased predator effect on aphid populations. By reducing both aphid quality and availability, increasing their susceptibility to parasitism, and modulating predator effect on aphid populations, we highlighted that viral endosymbionts can be prevalent drivers of their host ecology as they modify their phenotypes and interspecific interactions. These virus‐mediated ecological effects may have consequences on enemies foraging strategies as well as trophic webs dynamics and structure.
