| Popis: | Egg parasitoid rearing on factitious hosts is an important step to reduce costs and increase availability of the biocontrol agent but it requires quality control to achieve success in field conditions. To this end, this study evaluated the quality ofTelenomus remus(Hymenoptera: Platygastridae) reared onCorcyra cephalonica(Lepidoptera: Pyralidae) for until 45 generations. In the first bioassay, we evaluated the body size of the laboratory-produced parasitoids. In the second bioassay, flight activity was examined, measuring the percentage of ‘flyers’, ‘walkers’ and ‘deformed’ parasitoids. The third bioassay assessed parasitism onSpodoptera frugiperda(Lepidoptera: Noctuidae) eggs. Our data indicate that the laboratory-reared parasitoid neither lost its ability to fly nor to parasitizeS. frugiperdaeggs. In conclusion, quality did not decrease significantly during 45 generations, and therefore rearing ofT. remusonC. cephalonicaas factitious host promises to be successful. |
