“…Indeed, superparasitism is one of the main factors that may lead to high‐induced mortality, as previously reported for both A. daci (de Pedro et al, , ,b, ) and D. longicaudata (Montoya et al, ). Our work concurred with these studies with regards to higher induced mortality at lower host density (when superparasitism is also higher) and under greenhouse conditions.…”

“…Thus, the parasitoid that first oviposits into the host prevails in intrinsic competition, and eliminates or supresses the competing species through physical attack and/or physiological suppression (Cusumano, Peri, & Colazza, ; Harvey, Poelman, & Tanaka, ). Furthermore, most parasitoids (including D. longicaudata and A. daci ) can discriminate between parasitised and unparasitised hosts, rejecting the host in the former case and, consequently, avoiding superparasitism, especially when host densities are high (de Pedro, Tormos, Asís, Sabater‐Muñoz, & Beitia, ; Devescovi et al, ; Montoya, Cancino, Pérez‐Lachaud, & Liedo, ).…”

“…The D. longicaudata colony was established in 2009 from Anastrepha ludens (Loew) (Diptera: Tephritidae) infested pupae introduced from Mexico (rearing conditions: 25 ± 2°C, 65 ± 10% RH, 16:8 h [L:D] photoperiod) (Harbi, ). Meanwhile, the A. daci colony was established in 2010 with specimens obtained from medfly larvae taken from figs in the Valencian village of Bétera (Spain) and has since been maintained on medfly under the same rearing conditions as D. longicaudata (de Pedro, ).…”

In biological control programmes, it is very common to employ multiple species to manage a single insect pest. However, the beneficial effects of natural enemies are not always additive because of several factors, including interspecific competition between these biocontrol agents.For this reason, in the present study we assessed several biological parameters (percentage parasitism, fertility, induced mortality and population reduction) of the parasitoids Diachasmimorpha longicaudata and Aganaspis daci when used together against the medfly Ceratitis capitata under laboratory and greenhouse conditions. Our results showed that, under laboratory conditions, fertility and percentage parasitism corresponded to a different functional response for each species (D. longicaudata: type II; A. daci: type III), whilst under greenhouse conditions, and unlike what occurs with single releases, both parasitoids showed a type III functional response; this is the only response which may lead to direct density dependence when host densities are low.Our results also revealed that when both species acted together, they produced a very high total percentage parasitism compared to that reported for single releases under both laboratory (64-76%) and greenhouse (21-51%) conditions. The parasitism was also higher for A. daci except when medfly larvae were provided in an artificial diet. Furthermore, host mortality induced by the two parasitoids acting together was very high, especially at low-host densities; medfly population was almost completely reduced under greenhouse conditions. In summary, the data reported here supports the combined use of these species in biological control programmes against the medfly and highlights the importance of several factors, such as climatic conditions and host density, when planning their field releases.

“…Such feature suggests that D. juglandis, D. mellea , and A. alujai are good candidates for classical or augmentative biological control in areas were R. completa is currently invasive. In the case of A. alujai , this may be true only for areas experiencing mild winters, such as for example, low elevation areas in Italy (Poggetti et al 2019) or for Spain, where another species in the genus Aganaspis has been found to be associated with the Mediterranean fruit fly, Ceratitis capitata Wiedemann (de Pedro et al 2018).…”

The walnut husk fly Rhagoletis completa (Cresson), native to the Midwestern United States and Mexico, is invasive in California and Europe. It is one of the most important pests of walnuts in areas gathering 30% of the world production. Knowledge of life-history regulation is important for the design of management strategies. Research on dormancy has been performed on invasive populations, and not on populations at the southern extreme of its native range. Here, we examined the effect of winter length on fly and parasitoid emergence, survival, and duration of dormancy. Percent emergence was higher for chill periods at 5°C ranging from 8 to 20 wk. No or insufficient chill resulted in low emergence and a significant proportion of individuals in prolonged dormancy (>1 yr). Duration of dormancy was longer for pupae at constant temperatures and a 4-wk chill period than longer winter durations. Dormancy was longer for Mexican than that reported for U.S. populations, suggesting the existence of a latitudinal cline where populations at southern latitudes have evolved slower metabolic rates. Three parasitoid species were found associated with R. completa ( Aganaspis alujai (Wharton and Ovruski) (Hymenoptera: Figitidae), Diachasmimorpha juglandis Muesebeck, and Diachasmimorpha mellea Gahan) (Hymenoptera: Braconidae). Results suggest that rearing of R. completa is possible by subjecting pupae to chill periods between 8 and 20 wk. Overwintering mortality of flies and A. alujai could be further reduced above 5°C. Our findings can contribute for the accurate development of predictive models on invasion potential, development, fly and parasitoid rearing, and biological control.

“…M. Ovruski & Schliserman, 2012;Vargas et al, 2012). So far, no viruses have been associated with the larval-pupal endoparasitoid Aganaspis daci (Weld) (Hymenoptera: Figitidae), which is used in biological control programs against medflies (de Pedro et al, 2018). In addition, it is unknown whether viruses present in medflies affect the interactions between medflies and the parasitoid wasp A. daci.…”

Background: With the advent of high-throughput sequencing, large sets of insect-infecting RNA viruses producing apparent asymptomatic infections are being discovered. In the Mediterranean fruit fly (medfly) Ceratitis capitata, an agricultural key pest of a wide range of fruits, up to 13 different RNA viruses have been described. Recent analysis demonstrated a wide distribution of these viruses in different medfly strains collected worldwide, but little is known about the interactions between those viruses and the medfly host. Previous studies suggested that a higher abundance of Ceratitis capitata nora virus (CcaNV) decreased medfly developmental time. Here, we investigated the effect of CcaNV on a broad range of parameters related to host fitness and its interaction with other trophic levels. Results: CcaNV purified from a naturally infected medfly strain was used to infect CcaNV-free flies orally and subsequently monitor pupal weight, adult emergence, flying ability, and longevity. Our results revealed detrimental effects associated with a CcaNV infection in the medfly, in terms of reduced pupal weight and reduced adult longevity. Moreover, we tested the influence of a CcaNV infection in medflies on the parasitism performance of Aganaspis daci, a medfly endoparasitoid used in biological control programs against medflies. Our results showed that A. daci progeny increased when parasitizing on CcaNV-infected larvae. Conclusions: Our results proved that covert RNA viruses can impact on the insect ecology, directly affecting its insect host biology and indirectly influencing multitrophic interactions.
