Article Title: Identification and Functional Analysis of a Novel Cytochrome P450 Gene CYP9A105 Associated with Pyrethroid Detoxification in Spodoptera exigua Hübner

doi: 10.3390/ijms19030737

Figure Lengend Snippet: Effects of α-cypermethrin, deltamethrin or fenvalerate on CYP9A105 expression in midguts ( A ) and fat body ( B ) Spodoptera exigua . Insects were treated with insecticides at LC 15 doses (α-cypermethrin, deltamethrin and fenvalerate at 0.10, 0.20 and 5.00 mg/L, respectively) and LC 50 doses ( α -cypermethrin, deltamethrin and fenvalerate at 0.25, 0.40 and 10.00 mg/L, respectively), for comparison with control treatments. RT-qPCR analysis was used to determine relative transcript levels. Data shown are mean ± SE derived from three biological replicates. Different letters above bars indicate significant differences ( p < 0.05) according to the Duncan’s multiple range test.

Article Snippet: Meanwhile, S. exigua became highly resistant to β -cypermethrin in 2008 with resistance ratios ranging from 95.31-, 437.97-, 98.18-fold for the Taian, Zhangqiu, Anqiu populations [ ].

Figure Lengend Snippet: Effect of dsCYP9A105 injection on susceptibility of fourth-instar larvae of S. exigua to α -cypermethrin, deltamethrin and fenvalerate. Following injection with dsCYP9A105 or double-stranded green fluorescent protein (dsGFP), larvae were maintained on the different insecticide-treated cabbage leaves for 48 h. Data shown are mean ± SE derived from three biological replicates. Asterisk indicates a significant difference between dsGFP injected individuals compared with dsCYP9A105 injected individuals ( p < 0.05, Student’s t -test, ** p < 0.01, *** p < 0.001).

Figure Lengend Snippet: Statistically significant fold-changes (absolute FC > 2 and p value < 0.05) in abundance of S. exigua OS proteins identified in both pairwise contrasts between leaf-fed (pepper and tomato) and AD-fed larvae

Article Snippet: S. exigua colony was originally founded from eggs provided by Andermatt Biocontrol AG (Grossdietwil, Switzerland) whereas S. littoralis colony was founded with pupae provided by Primitivo Caballero Murillo’s laboratory (Instituto de Agrobiotecnología, CSIC, Navarra, Spain).
