Reproduction of Trichospilus diatraeae in Diatraea saccharalis after three generations in Tenebrio molitor
The successive rearing of parasitoids in factitious hosts may affect its biological quality. Trichospilus diatraeae Cherian & Margabandhu, 1942 (Hymenoptera: Eulophidae) has been studied for the biological control of sugarcane borer [Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae...

The successive rearing of parasitoids in factitious hosts may affect its biological quality. Trichospilus diatraeae Cherian & Margabandhu, 1942 (Hymenoptera: Eulophidae) has been studied for the biological control of sugarcane borer [Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae)]. This study aimed to evaluate whether the rearing of T. diatraeae for three generations in the factitious host Tenebrio molitor Linnaeus, 1758 (Coleoptera: Tenebrionidae) affects its reproductive performance, when subsequently reared in the natural host pupae D. saccharalis. Two groups of T. diatraeae were reared separately for three generations: one in pupae of T. molitor and the other in pupae of D. saccharalis. Subsequently, 20 pupae of D. saccharalis were exposed, for 72 hours, to the parasitism of T. diatraeae females reared earlier in pupae of T. molitor or D. saccharalis. The successive rearing of T. diatraeae in the factitious host did not affect the number of pupae parasitized and the number of pupae in which the emergence of parasitoids occurred in the natural host D. saccharalis, and increased the longevity of females and the sex ratio of T. diatraeae. The progeny, duration of developmental cycle (egg to adult), width of head capsule of males and females and longevity of males of T. diatraeae were similar on both treatments. T. diatraeae can be reared in the factitious host T. molitor for three generations without compromising its reproductive performance, when subsequently reared in the natural host D. saccharalis. |
