Heatmap showing the influence of three insecticides and the sex pheromone on the expression levels of 18 Takeout genes in S. litura male adults after a 1 d and 2 d treatment. 1 d: expression changes in TO genes in male S. litura after 1 d of insecticide or sex pheromone treatment; 2 d: expression changes in TO genes in male S. litura after two days of insecticide or sex pheromone treatment; CK: control; Ch: chlorpyrifos; EB: emamectin benzoate; Fi: fipronil; P: sex pheromone. Hierarchical average linkage was used as the clustering method.
