밤나무혹벌 유충기(幼蟲期)의 유약(幼若) 호르몬의 활성(活性) = Juvenile Hormone Titer in the Whole Body during Larval Stage Chestnut Gall Wasp, Dryocosmus kuriphilus Yasumatsu

다국어 초록 (Multilingual Abstract)

The juvenile hormone titers were measured in whole body extracts of chestnut gall wasp larva, Dryocosmus kuriphilus Yasumatsu, parasiting in one susceptible and two resistant chestnuts by Galleria bioassay and GLC. The juvenile hormone titer of chestnut gall wasp was showed higher activity in two resistant chestnut (Cheuk-Pa, Dan-Tak) than susceptible one. The juvenile hormone titers chestnut gall wasp were showed Cheuk-Pa(35,800 GU/g), Dan-Tak(30,900 GU/g) parasiting in two resistant chestnut, parasiting in susceptible(28,600 GU/g). The positive responses of Galleria cuticle wax test were showed Cheuk-Pa(60.8%), Dan-Tak(63.9%), and susceptible(59.0%). After precipitation at low temperature, the lipid is separated by thin layer chromatography, and identification of chestnut gall wasp JH by gas liquid chromatography was showed JH-I.
