Impact of irradiated Drosophila melanogaster pupae on the quality and population parameters of Trichopria drosophilae

Trichopria drosophilae is a globally distributed pupal parasitoid that targets various species within the Drosophilidae family, including the invasive Drosophila suzukii. The mass rearing of T. drosophilae is a crucial step in ensuring their successful application for field D. suzukii. control. The pupae of Drosophila melanogaster are currently used as a host for the mass rearing of T. drosophilae. The impact of utilizing irradiated pupae on T. drosophilae was investigated. Our results showed that irradiated pupae had a significant impact on the parasitism rate, offspring eclosion rate, offspring number, and female body size of F1 T. drosophilae, all of which were significantly lower than those in the normal group. However, there was no significant difference in parasitism rate, body size, offspring eclosion rate, offspring number, and offspring sex ratio between F2 T. drosophilae emerging from the two types of Drosophila pupae. Compared to F2, F1 had a significantly higher net rep..., Insects
Laboratory colonies of D. melanogaster and T. drosophilae were collected from blueberry orchards in Huangtai Village, Wuhu, Anhui Province, P.R. China. All collected insects were reared in controlled environments within artificial climate chambers (25 ± 1℃, 65 ± 5% RH, 12:12 h (L/D)). Drosophila melanogaster were collected from Anhui Normal University, Anhui Province, China, in 2010 (31.33°N, 118.37°E), reared in nylon cube cages (35×35×35 cm). Drosophila melanogaster were fed a 240-ml plastic cup containing 80 ml of solid food (water: 1000 ml, corn flour: 44.67 g, sucrose: 71.33 g, agar: 16.00 g, yeast: 25.00 g, propionic acid: 6.30 ml, 100% ethanol: 22.30 ml). The plastic cup containing food is replaced daily, and the removed cups are kept in the climate chamber. Once the larvae pupate on the walls of the plastic cups, the cup walls are removed and provided for parasitism by T. drosophilae. T. drosophilae were reared in plastic insect rearing containers (diameter: 10 cm, heigh..., , # Impact of irradiated Drosophila melanogaster pupae on the quality and population parameters of Trichopria drosophilae
