Özet

Graphosoma lineatum is the suitable host of Sunn pest (Eurygaster spp.) egg parasitoids. Fecundity, adult lifespan, preoviposition, oviposition and postoviposition periods, nymph development periods according to nymph stages and as total, nymph ratios of reaching to adult stage of Grapohosoma lineatum (L.) were determined on different plants from Apiaceae. Studies were carried out in laboratory under 27 +/- 2 degrees C temperature, 45 +/- 5% RH and 16 hours photoperiod conditions. Plants were presented weekly to insects collecting them from preflowering stage to ripping stage (June-September, 2006) from Ayas, Beypazari and Kizilcahamam counties in Ankara province. The average fecundity of the insect on Torilis arvensis (Huds.), Daucus carota (L.), Heracleum platytaenium (Boiss.), Conium maculatum (L.) and Astrodaucus orientalis (L.) as 178.0, 185.2, 196.0, 415.0 and 170.2, respectively; and the female lifespan was 56.67, 56.67, 51.50, 71.00 and 60.00 days; male lifespan was 55.67, 73.17, 58.83, 88.50 and 49.17 days; preoviposition period was 21.66, 12.50, 15.33, 11.50 and 18.00 days; oviposition period was 31.50, 33.67, 26.83, 57.17 and 35.83 days; postoviposition period was 3.50, 8.83, 9.00, 2.33 and 6.16 days; nymphs ratios reaching to adult stage 47.50%, 82.50%, 82.50%, 85.00% and 67.50%; and total nymphal period was 25.70, 22.20, 20.75, 18.85 and 24.10 days. The shortest nymhp development periods were determined as 1, 3, 2, 4 ve 5 according to nymph stages. Generation durations as the shortest 35.35 days on C. maculatum and the longest 51.36 days on T. arvensis were determined. These results show that C. maculatum and H. platytaenium were the most suitable food sources while T arvensis and A. orientails were not for G. lineatum.
