parasitoids of the eucalyptus gall wasp leptocybe invasa (hymenoptera: eulophidae) in china.leptocybe invasa fisher & la salle (hymenoptera, eulophidae) is an invasive pest in eucalyptus plantations throughout the world. potential biological control agents for l. invasa were investigated in the fujian, guangdong, hainan, guangxi, jiangxi, and sichuan provinces of china, where eucalyptus spp. have been severely damaged by the eucalyptus gall wasp. three hymenopteran parasitoids of l. invasa were identified: quadrastichus mendeli kim & la salle (eulophidae), aprostocetus causalis la sall ...201628000590
[application of two ftir pattern recognition methods to the zanthoxylum nitidum geographical origins determination].in the present work, the authors explored a rapid method of the zanthoxylum nitidum geographical origins determination. based on fourier transform infrared spectroscopy (ftir) technology, the band of 1 800-400 cm(-1) which is the ir fingerprint of zanthoxylum nitidum, the fisher ratio and the soft independent modeling of class analogies (simca) were used to build a classification model. respectively, four kinds of zanthoxylum nitidum in the guangxi region were detected by the model, and the mode ...201122250538
