“…Among these ligands, both 2-butyl-2-octenal and cis-3-hexenyl butyrate could elicit significant EAG responses in B. dioryctriae, yet only 2-butyl-2-octenal had a behavioral influence on parasitic wasps. Cis-3-hexenyl butyrate is a common herbivore-induced plant volatile that can also elicit EAG responses of other parasitic wasps, such as Microplitis croceipes and Cotesia marginiventris, 40 and the detailed function of this volatile in B. dioryctriae will be further investigated by other behavioral tests in our future work, as it might be an enhancing factor for other semiochemicals and may not mediate wasp behavior directly. 2-Butyl-2-octenal is emitted from the pine nut of Pinus koraiensis and the wood of Pinus sylvestris, 41,42 and Pinus cones are the main foods for B. dioryctriae host larvae.…”

Reverse chemical ecology has been widely applied for the functional characterization of olfactory proteins in various arthropods, but few related studies have focused on parasitic wasps. Here, the odorant carrier Niemann−Pick C2 protein of Baryscapus dioryctriae (BdioNPC2b) was studied in vitro and in vivo. Ligand binding analysis revealed that BdioNPC2b most strongly bound to 2-butyl-2-octenal and which compound could elicit an EAG response and attracted B. dioryctriae adults. Moreover, this odorant attractant significantly improved the reproductive efficiency of B. dioryctriae compared to that of the control. Then, the relationship between BdioNPC2b and 2-butyl-2-octenal was validated by RNAi, and site-directed mutagenesis revealed the involvement of three key residues of BdioNPC2b in binding to 2-butyl-2-octenal through hydrogen bonding. Our findings provide not only a deeper understanding of the olfactory function of NPC2 in wasps but also useful information for improving the performance of the parasitoid B. dioryctriae as a biological control agent.

“…Indeed,Vayssières et al ( , 2012,Badii et al (2016),Sambo et al (2019),Zida et al (2022) have shown that in S. latifolius associated mainly with C. cosyra, F. caudatus was the most abundant and frequent native parasitoid than other native species such as D. fullawayi, Fopius silvestrii(Wharton), Fopius desideratus (Bridwell), Psyttalia concolor (Szépligeti), Psyttalia cosyrae (Wilkinson). In addition, as shown by the work ofGripenberg et al (2010),Quilici and Rousse (2012),Cusumano et al(2016),Ayelo et al (2017),Das et al (2017) in other parasitoids, females of F. caudatus are probably able to more easily identify (locate) the fruits of…”

Fruit flies (Diptera: Tephritidae) are major pests associated with fruit and vegetable production in West Africa in general and in Togo in particular. The use of parasitoid wasps to significantly reduce their populations in agroecosystems is a significant component of the integrated management of these pests (IPM-package). To do this, it is important to know their diversity, distribution and potential in controlling fruit flies. In this perspective, the incubation of 28 species of fruits and vegetables sampled in 2009 in ecological zones III, IV and V in Togo allowed to identify five species of native braconid parasitoids: Fopius caudatus Szepligeti, Diachasmimorpha fullawayi Silvestri, Bracon sp., Fopius sp. and Psyttalia sp. F. caudatus was the most abundant making 98.6% of parasitoids recovered. These parasitoids were associated with 4 species of fruit flies, the most abundant being the native species, Ceratitis cosyra (Walker). The parasitism rate in the three ecological zones depended on the locality, the incubated fruit and the fruit fly species. It was relatively low and ranged from 0 to 42.31%, with the highest average rate recorded in the wild fruit, Sarcocephalus latifolius (Sm.) E.A.Bruce, associated exclusively with C. cosyra. Pupae recorded from S. latifolius frequently yielded F. caudatus which was the most abundant. Assessment of the demographic parameters of F. caudatus, a potential candidate for augmentative biological control of C. cosyra in Togo, should be considered under controlled and natural conditions.
