“…In our study, all females were capable of reproduction, which demonstrated the high reproductive potential of H. hebetor on E. elutella . It indicated that the relationship between the mean fecundity ( F ) and the net reproductive rate ( R 0 ) in all treatments was consistent with the mathematical formula R 0 = F ( N f / N ), where N is the initial number of individuals used for the study and N f is the number of female adults emerged 16 . The life table data was used for population projection, which is useful for estimating population growth potential 33, 44 .…”

BACKGROUND Habrobracon hebetor (Hymenoptera: Braconidae) is a gregarious ectoparasitoid that attacks the larvae of several species of pyralid and noctuid moths. The reproduction and population dynamics of parasitoids in general are affected by host deprivation. However, how host deprivation affects H. hebetor is unknown. The effect of host deprivation on the parental generation, life table parameters, and the paralysis rate of the F1 generation of H. hebetor were evaluated using the age‐stage, two‐sex life table under laboratory conditions. RESULTS The results indicated that the greatest longevity and the least lifetime fecundity of the F0 generation occurred after 19 days of host deprivation (PW‐20 treatment). The life table parameters (intrinsic rate of increase, r; finite rate of increase, λ; and net reproductive rate, R0) and the paralysis rate parameters (net paralysis rate, C0; transformation rate, Qp; stable paralysis rate, ψ; and finite paralysis rate, ω) of F1 individuals after PW‐20 treatment were significantly higher than those of individuals subjected to the control treatment (no host deprivation). However, no difference was detected between the two host deprivation treatments: host deprivation after 1 day of host contact and immediate host deprivation (PW treatment). CONCLUSION Our results demonstrated that the effectiveness of H. hebetor did not decrease even during host deprivation for 19 days. Meanwhile, it was observed that mass rearing of the parasitoid could be improved by providing 10 individuals of 5th instar larvae of Ephestia elutella (Lepidoptera: Pyralidae) with a 20% honey‐water solution. © 2020 Society of Chemical Industry

“…Furthermore, H. hebetor populations in India are able to shift from field hosts in the rainy season to stored-product hosts in the off-season. It is also possible that the source of our H. hebetor population is significantly limiting its fitness in the released location (Saadat et al, 2014(Saadat et al, , 2016Borzoui et al, 2016).…”

“…In this regard, there are various successful paradigms of control of stored product moths using H. hebetor [2,3]. At the same time, naturally-occurring populations of this species have been frequently found in several parts of the world [4], while it is able to develop easily high population densities, provided there is sufficient number of large host groups [5]. Nevertheless, apart from quantity, which has an apparent influence of population growth, host quality is probably the key element that determines the reproductive success of a given parasitoid.…”

We evaluated possible improvements to the mass rearing of the larval parasitoid Habrobracon hebetor (Say) (Hymenoptera: Braconidae) on irradiated host wax moth Galleria mellonella L. and Indian meal moth Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) larvae. The use of irradiated G. mellonella and P. interpunctella larvae at the dose of 150 Gy proved useful for enhancing the parasitism and adult emergence of H. hebetor due to the absence of negative repercussions on parasitoid development. Overall, parasitism was increased as the host larvae was irradiated with higher doses, while significantly higher parasitism was recorded at 150 and 300 Gy compared to lower doses. The female parasitoids preferred the irradiated larvae and significantly higher numbers of larvae were parasitized compared with non-irradiated larvae. The results also showed that irradiated larvae of G. mellonella served better as hosts for H. hebetor as compared with irradiated larvae of P. interpunctella. The implementation of these findings would be helpful for improving the mass production of parasitoids and the effectiveness of releases of biocontrol agents for the control of stored product pests.
