Sumario:Beneficial insects, such as biological control agents (BCAs), play a crucial role in agriculture [1,2]. A conservative study estimated the annual value of natural control attributable to beneficial insects to be about 4.5 billion dollars in the USA alone [3]. In Europe, biological control is a cornerstone of pest management under the new European Green Deal. Most BCAs are omnivores, feeding on both pests and plant-derived food sources [4]. This omnivory has led to the use of food supplements to support beneficial organisms in agricultural systems. For example, nectar, pollen, extrafloral nectar, plant guttation, and honeydew have been identified as important plant-derived food sources for BCAs in ecosystems. These plant-derived products provide a rich source of carbohydrates and proteins, significantly enhancing the success of biological pest control. However, the availability of these food sources can be highly variable [4], making their presence unpredictable for foraging insects. Many of these sources are ephemeral (e.g. pollen or floral nectar), and their quality as a food source is variable (e.g. honeydew or plant guttation) [5–7]. In this issue, we delve deeper into these complexities, offering recent advances on the role of plant-derived food sources for beneficial insects and the potential for their management to enhance biological control.
