Figure 4. Captures of adult Apolygus lucorum in bucket traps in greenhouse cage experiments.

Before each trial, 200 A. lucorum adults were released into each cage. 2: m-xylene; 3: Butyl acrylate; 4: Butyl propionate; 5: Butyl butyrate. The data on the y-axis are mean ± SE. For each release concentration, significant differences (P < 0.05) between compounds are denoted by different letters (uppercase letters, 300 mg/ml; lowercase letters, 100 mg/ml). *denotes a significant difference between two doses (P < 0.05), and ns shows no difference (P > 0.05). Four replicates were conducted for each dose.
