中文摘要 | 來自外米綴蛾卵之Trichogramma chilonis對紫外光燈照射或未照射黃螟卵之寄 生率為80.3-83.2%,每隻母蜂產子8.60-9.10隻;對照射或未照射亞洲玉米螟卵之寄生率僅 1.2-7.2%,平均產子0.10-0.35隻。另一方面,來自玉米螟卵之T. ostriniae對照射或未照射 黃螟卵之寄生率為43.3-55.3%,每雌產子3.98-5.02隻,對照射或未照射玉米螟卵之寄生率與 產子數,則分別為69.1-75.7%與4.76-5.98隻。若混合10隻T. chilonis雌蜂與10隻T. ostriniae雌蜂時,對黃螟卵之寄生率為71.3-77.5%,所產子代中T. chilonis佔79.6-85.5%, 兩蜂種所佔百分率似與兩種母蜂之寄生率與繁殖子代數乘積比值之關係密切;對玉米螟卵之 寄生率則為47.9-50.1%,所產子代中T. chilonis只佔2.9-7.4%。寄主卵是否經過照射,似未 影響被寄生率、羽化率與母蜂之產子數。 |
英文摘要 | When irradiated and nonirradiated eggs of Argyroploce schistaceana were separately provided to Trichogramma chilonis reared from the eggs of Corcyra cephalonica, 80.3%-83.2% parasitism with 8.60-9.10 F□ progenies produced per parental female were observed. Furthermore, 1.2-7.2% parasitism with only 0.10-0.35 F□ progenies per female resulted when irradiated and nonirradiated Ostrinia furnacalis eggs were provided. On the other hand, the parasitism on A. schistaceana eggs was 43.3-55.3% with 3.98-5.02 F□ progenies per female by T. ostriniae raised from O. furnacalis eggs. The parasitism of these parasitoids on O. furnacalis eggs was 69.1-75.5%, with the production of 4.76-5.98 F□ progenies per female. When 10 female T. chilonis and 10 female T. ostriniae were placed simultaneously in a container with A. schistaceana eggs, the parasitic rate was 71.3-77.5%, with 79.6-85.5% of the F□ progenies found to be T. chilonis. The relative abundance of each Trichogramma species in the F□ population seemed to be related to the ratios of the products of the parasitic rate multiplied by the number of progenies per female of the respective species. However, 47.9-50.1% parasitism with only 2.9-7.4% of the progenies were T. chilonis when O. furnacalis eggs were exposed to mixed Trichogramma spp. Populations. The data also showed that irradiation of the host eggs did not significantly affect parasitism, the emergent rate, and the number of progenies per female. |
