“…These conditions are regarded as optimal for its development and parasitic activity (de Pedro, Beitia, Sabater‐Muñoz, et al, ). At other times of the year, A. daci development appears to be negatively affected by environmental conditions, whilst D. longicaudata seems to be more resistant to extreme climatic conditions (Harbi et al, ; Meirelles, Redaelli, & Ourique, ). Thus, it would be advisable to perform further field or semi‐field studies where both species are released in different seasons.…”

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.

“…Evaluation of the optimum temperature for development of a parasitoid is an important step in its mass production under laboratory conditions and inundative release in the fi eld and a basic requirement of any biological pest control programme (Meirelles et al, 2015). Temperature is one of the most important climatic factors infl uencing the distribution, abundance, immature development, adult emergence, fecundity, longevity and parasitism capability of egg parasitoids (Maceda et al, 2003;Liu et al, 2012).…”

“…The effectiveness of biological control programmes can be limited by adverse climatic conditions (Firake & Khan, 2014). The effects of temperature on D. longicaudata developing in different hosts is well studied; for instance, Meirelles et al (2013Meirelles et al ( , 2015 report that rapid development of D. longicaudata in Anastrepha fraterculus (Wiedemann) and Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is achieved at a constant temperature of 25°C. Liu et al (2012) suggest that the most appropriate temperature range for the reproduction and development of D .…”

The use of wide-spectrum chemical pesticides results in many secondary problems, such as environmental pollution, decreases in the abundance of natural enemies, presence of chemical residues in foods and resistance of this pest to pesticides (Zhang et al., 2014; Cai et al., 2017). Due to the ineffectiveness and undesirable consequences of using pesticides, parasitoid species, such as Fopius arisanus (Sonan), Psyttalia incisi (Silvestri), Fopius vandenboschi (Fullaway) and Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae), have been widely used to depress fruit fl y populations in many regions (Var

“…The impact of climatic conditions on Opiinae species has been demonstrated in previous studies reporting that parameters such as flight activity, parasitism rate, fecundity, adult and immature survival, field establishment and annual number of generations were mainly affected by temperature and humidity (Daane et al, 2008;Rousse, Gourdon, Chiroleu, & Quilici, 2009;Sime, Daane, Messing, & Johnson, 2006;Wang, Johnson, Yokoyama, Pickett, & Daane, 2011 (Appiah et al, 2013;Liu, Chen, & Zeng, 2012;Meirelles et al, 2015;Sime, Daane, Nade et al, 2006). Consequently, the correlation of these parameters with abiotic factors when attempting to perform an area-wide biological control programme constitute a cornerstone to guarantee the viability of introduced beneficial organisms in a new environment.…”

“…D. longicaudata is no exception as it has been demonstrated that abiotic factors, especially temperature, have effects on its biological parameters. In fact, temperature was proved to affect adult longevity, fecundity, parasitism rate and pre‐imaginal development of D. longicaudata on different host fly species such as B. invadens , B. dorsalis , B. oleae , A. fraterculus and C. capitata (Appiah et al., ; Liu, Chen, & Zeng, ; Meirelles et al., ; Sime, Daane, Nade et al., ). Consequently, the correlation of these parameters with abiotic factors when attempting to perform an area‐wide biological control programme constitute a cornerstone to guarantee the viability of introduced beneficial organisms in a new environment.…”

The larval–pupal endoparasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae) is currently the most commonly employed biological control agent against Tephritid fruit flies in the Americas. However, this parasitoid remains largely ignored and is not used in many regions, including the Mediterranean Basin. In this study, the potential of D. longicaudata as a biocontrol agent against the Mediterranean fruit fly (medfly) Ceratitis capitata (Diptera: Tephritidae) was addressed in an area of eastern Spain (the Valencian community). The parasitic activity of parasitoids and the effects of climatic conditions were evaluated throughout a 1‐year period in field‐cage experiments in which parasitoids were confined with apples artificially infested with medfly larvae. The following parameters were calculated and related statistically to several environmental conditions: the parasitism rate, the induced mortality and progeny sex ratio. The results show that D. longicaudata is able to parasitize medfly larvae throughout the year under semi‐natural conditions. Important fluctuations in the parasitism rate (from almost zero to 42%) and the induced mortality (from 6% to 80%) were partially influenced by climatic conditions. The parasitism rate increased with mean temperature and decreased with mean relative humidity, while the induced mortality decreased with minimum relative humidity. The optimal climatic conditions for the activity of the parasitoid were a mean temperature of 16–24°C combined with a relative humidity of 45%–60%. Overall, these results suggest that reduction in the medfly population due to D. longicaudata activity is feasible and provide information about the optimal time period for parasitoid release in the field. In conclusion, D. longicaudata has a significant potential to control C. capitata in the Mediterranean region.
