Physically acting bioinsecticides may offer an alternative control option, yet their efficacy against aphids and compatibility with natural enemies outside of horticultural production systems is poorly understood. Three bioinsecticides based on fatty acids, silicone polymers or surfactants were tested against two economically important aphid species and non-target effects on their natural enemies, <i>Diaeretiella rapae</i> M'Intosh adults and mummies as well as <i>Chrysoperla carnea</i> Stephens larvae, were also assessed.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> RESULTS</h3>\u0000 \u0000 <p>Under direct exposure, fatty acids, silicone polymers and surfactants all caused aphid mortality (<i>B.</i> brassicae 90–56%, <i>M. persicae</i> 63–20%) within 72 h. <i>Diaeretiella rapae</i> mortality was 100% 24 h after exposure to fatty acids and silicone polymers while <i>Chyrsoperla carnea</i> mortality was 66% and 100%, respectively.

Widespread pyrethroid insecticide resistance in this pest has severely limited the primary means of control for many growers, contributing to dramatic yield losses and a decline in OSR cultivation across Europe. This study evaluated SYN-A, a novel natural synergist derived from olive oil unsaturated fatty acids, for its potential to restore pyrethroid efficacy against CSFB while assessing impacts on the parasitoid <i>Microctonus brassicae</i>, a key natural enemy of the adult life stage.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> RESULTS</h3>\u0000 \u0000 <p><i>In vitro</i> enzyme assays demonstrated that SYN-A effectively inhibited cytochrome P450 and esterase activity – key metabolic pathways associated with pyrethroid resistance – in both CSFB and <i>M. brassicae</i> in a dose-dependent manner.

This review highlights the potential of ecologically optimized IPM strategies integrating habitat manipulation, behavioral conditioning, and evolutionary-informed approaches to optimize pest suppression. Habitat diversification, including intercropping, companion and banker plants, crop rotation, and landscape management, enhances natural enemy abundance and modifies pest behavior. Complementing this, natural enemy behavioral conditioning may improve host detection, foraging efficiency, and retention within diversified cropping systems. Evolutionary processes, such as host-associated differentiation (HAD), further stabilize natural enemy performance and align their activity with crop and pest dynamics. Aligning these strategies across ecological scales could improve pest suppression through complementary interactions. However, research is needed to translate behavioral and evolutionary insights into effective field-level IPM programs and quantify multi-tactic interactions.
