Recently, the result of 2016 Excellent Paper Award of Chinese Sci-tech Journals  was unveiled by CAST(China Association for Science and Technology). NWAFU Prof.Liu Tongxian’s team research paper “Combined effects of potassium and indole-3-acetic acid on tritrophic interactionsbetween common wheat Triticum aestivum ( Graminales: Poaceae),English grain aphid Sitobion avenae ( Hemiptera: Aphididae)and parasitoid Aphelinus asychis ( Hymenoptera: Aphelinidae)”was on the list, being the only excellent paper in the field of plant protection in agriculture. Doctoral student Di Ning was the first author of the paper, with Prof.Liu Tongxian as corresponding author.

The paper aims to explore the regulatory effects of the interaction of potassium and indole-3-acetic acid(IAA) on the growth and development of the three trophic levels in a banker plant system involving Triticum aestivum-Sitobion avenae - Aphelinus asychis. Hoagland solutions containing different concentrations of KCl and IAA solution were irrigated and sprayed on wheat respectively to measure the leaf physiological indices of the treated wheat plants,weight difference and several enzyme activities of the aphid S.avenae,the body length and activity of some enzymes of the parasitoid A.asychis, gaining best combinations of KCl and IAA with interactive effects, providing theoretical basis and applied technology for utilizing wheat to rear better alternative hosts(grain aphid Sitobion avenae) for the parasitoids and Aphelinus asychis.
