“…For instance, we have evaluated the numerical production of adult offspring but not their size, and size is known to affect the ability of females of some parasitoid species to forage for hosts in the field (Visser, 1994; Luck & Forster, 2003), their survival, and also fecundity (Hardy et al, 1992; Godfray, 1994; Gao et al, 2016). There may also be a variation in parasitoid performance over generations of rearing on a given host (Nunney, 2003; van Lenteren et al, 2003; Pratissoli et al, 2004; Li et al, 2010), possibly due to associative learning of cues emanating with the factitious host, rather than the target host (Vet et al, 2003; Men et al, 2019). Such effects remain largely unassessed for S. brevicornis , although some evidence suggests that females reared on C. cephalonica attack and lay eggs on C. cephalonica larvae less rapidly than do those reared on a coleopteran host (Abdi et al, 2020).…”

“…Morphological characteristics of Sclerodermus enable them to find and attack their hosts in enclosed spaces, such as feeding tunnels (Kühne & Becker, 1974; Evans, 1978; Yang et al, 2012a; Baena & Zuzarte, 2013; Jiang et al, 2015). Some species are of considerable economic importance, as they are used in biological control programmes (Yang et al, 2014) whereas others may be medically detrimental (Evans, 1978; Papini, 2014; Yang et al, 2014; Skvarla, 2018; Men et al, 2019).…”

Biological control efficiency can be improved by developing effective mass-rearing systems to produce large numbers of high-quality parasitoids. This study explored an alternative host for rearing Sclerodermus brevicornis (Kieffer) (Hymenoptera: Bethylidae), a potential biocontrol agent for the suppression of exotic and invasive wood-boring longhorn beetle (Coleoptera: Cerambycidae) populations in the European agroforestry ecosystems. We tested larvae of the rice moth, Corcyra cephalonica Stainton (Lepidoptera: Pyralidae), as host for the parasitoid. We quantified the probability and timing of host attack and parasitism as well as reproductive success, offspring production, and the characteristics of adult offspring. As S. brevicornis is a quasi-social species (multiple females, communally produced offspring broods), we also explored the effects of varying the number of females to which individual hosts were presented, with the aim of determining the optimal female-to-host ratio. As time to host attack can be a limiting factor in S. brevicornis rearing protocols, we tested the use of adult females of another bethylid species, Goniozus legneri Gordh, to paralyse C. cephalonica larvae prior to presentation. We identified the conditions within our experiment that maximized offspring production per host and offspring production per adult female parasitoid. We found that C. cephalonica is suitable as a factitious host and, as it is considerably more straightforward for laboratory rearing than cerambycid species, it is a good candidate for adoption by future S. brevicornis mass-rearing and release programmes.

“…Stimulated by successes in agro-forestry systems in China [ 47 ], there is growing interest in the use of parasitoids in the bethylid genus Sclerodermus Latreille. These are idiobiont ectoparasitoids [ 48 , 49 ], typically attacking coleopteran larvae, mainly wood-boring beetle larvae (Cerambycidae, Scolytidae, Anobiidae and Bostrichidae) [ 50 , 51 ]. Their flattened body and their strong mandibles allow them to enter narrow places in search of hosts, excavating in the frass of pre-existing galleries bored in the wood by the xylophagous beetles [ 50 , 52 , 53 , 54 , 55 ].…”

Many species of long-horned beetles are invasive pests causing significant economic damage in agro-forestry systems. They spend the majority of their life-cycle concealed inside natural wood or wooden packaging materials and are largely protected from adverse environmental conditions and pesticide sprays. Biological control via parasitoid natural enemies including members of the bethylid genus Sclerodermus, has proven effective against some long-horned beetles that are invasive in China. In Europe, the biocontrol potential of native Sclerodermus species is being evaluated with a view to developing efficient mass-rearing techniques and then actively deploying them against invasive Asian beetles. Here, we continue evaluations of S. brevicornis by establishing that groups of females that have already reared offspring to emergence are capable of reproducing subsequent hosts and by evaluating the lifetime reproductive capacity of individual females provided with successive hosts. Additionally, we assess the laboratory shelf-life of adult females stored for different times at different temperatures including cold storage, and then assess the post-storage reproductive performance of groups of females provided with a single host. We found that adult female longevity declines with increasing storage temperature and that most aspects of subsequent performance are negatively affected by high temperatures. The adaptability to low temperature storage enhances the suitability of S. brevicornis to mass-rearing programs and thus biocontrol deployment.

“…As phytophagous insects, Cerambycidae are economically important pests of street trees and forests [ 7 ], with more than 36,000 described species worldwide [ 8 ]. In recent years, more research on pheromones and behavior of longhorn beetles has been done, such as host location [ 7 , 9 ], mating [ 10 , 11 ], oviposition [ 12 ], thanatosis (death-feigning) [ 13 ], and sex and aggregation pheromones [ 14 ]. Behavior is inseparable from signaling and signal reception.…”

Allotraeus asiaticus Schwarzer and Callidiellum villosulum Fairmaire are repeatedly intercepted in wood and wood products all over the world. As two common stem borers of Cunninghamia lanceolata (Lambert) Hooker, to further understanding of the differences in their living habits, behaviors and the mechanism of insect-host chemical communication, we observed the external morphology, number and distribution of antennal sensilla of A . asiaticus and C . villosulum with scanning electron microscopy (SEM), respectively. The results showed that 1st-5th subsegments of the flagellum are spined endoapically in A . asiaticus which is different from the previous report (1st-3rd of the flagellomere). Meanwhile, there were five subsegments on the flagellum of C . villosulum that were clearly specialized as serrated shapes on the 4th-8th flagellomeres. Four types (ten subtypes) of sensilla were both found on the antennae of these two fir longhorn beetles, named Böhm bristle (Bb), sensilla trichodea (ST I and II), sensilla basiconica (SB I, II and III), sensilla chaetica (SCh I, II, III and IV). There is one additional kind of morphological type of sensilla found on the antennae of C . villosulum compared to A . asiaticus which was related to their habit of laying eggs only on dry and injured fir branches, named sensilla campaniformia (SCa). These differences may vary according to their own biological habits. For research purposes, the observed difference in the sensillum distribution and function between the two fir longhorn beetles will greatly facilitate the design of better semiochemical control methods of these insect pests.
