In this context, honeydew (the aphid excretory product), rich in sugars and amino-acids, constitutes a nutritional resource for beneficials but also acts as a volatile and a contact kairomone. On one hand, honeydew volatile chemicals cues guide beneficials to a food source, hosts or preys but also stimulate particular behaviors : searching, preys/hosts locations and attacks. On the other hand, a contact with honeydew induces the oviposition especially for syrphids (Episyrphus balteatus, …). The use of an artificial honeydew could be a way for enhancing the biological control efficiency in fields by increasing the number of beneficials but also the predation and parasitic rates.
