Effects of companions plants on the behavior of the green peach aphid reared on pepper plants

Abstract : Mixing horticultural plants with companion plants (CP) was proposed as an alternative method to control green peach aphid populations. Basil, lavender and rosemary were assessed as CP associated with pepper plants subjected to aphid infestation: i) on mesocosms in growth chambers and ii) in olfactometers. When pepper was associated with rosemary, lavender or basil, female fecundity was significantly reduced. In addition female flight was the most important in the presence of rosemary compared to other CP. Olfactory tests revealed that basil plants had a repellent effect on aphids. Our results sustain the hypothesis that associating CP with horticultural crops may be useful in reducing aphid populations.
