Fig. 4 Behavioral responses of female (A) and male (B) Lygus pratensis to volatiles from six host plants * means significant difference between treatment and control (P < 0.05); ** means extremely significant difference between treatment and control (P < 0.01); ns means no significant difference (P ≥ 0.05).
Fig. 6 Occurring number of Lygus pratensis in cotton fields CK: control cotton field. Mean values with the same letters indicate no significant difference (P ≥ 0.05) between insect numbers per 100 plants of investigation points at different distance to rape trapping belt, but different letters indicate significant difference (P < 0.05).
