AbstractEgg 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 of Telenomus remus (Hymenoptera: Platygastridae) reared on Corcyra 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 on Spodoptera frugiperda (Lepidoptera: Noctuidae) eggs. Our data indicate that the laboratory-reared parasitoid neither lost its ability to fly nor to parasitize S. frugiperda eggs. In conclusion, quality did not decrease significantly during 45 generations, and therefore rearing of T. remus on C. cephalonica as factitious host promises to be successful.

The objectives of this study were to evaluate the sperm viability of Najawa carp (Cyprinus carpio L.) in cryopreservation pre-conditions at 4°C. The design used in this study was Complete Randomized Design with 4 treatments, BSS as a control, 10% DMSO, 0,2 M Sucrose, and 5% DMSO + 0,1 M Sucrose; each consist of three replications. The parameters observed were progressive motility of fresh sperm, diluted sperm before low temperature storage, and 2 hours; 3 hours; 4 hours; 5 hours; one day; one week; a month after 4°C storage. The data were analyzed by ANOVA. The data showed that there was no significant difference between treatment (P>0.05). The best viability was 40.56% of sperm motility which survive for one week, it was achieved by 5% DMSO + 0,1 M Sucrose.
