“…One such approach, provision of natural enemies with naturally occurring non-host food resources (e.g. nectar, honeydew, pollen), provides energy for maintenance, locomotion and reproduction, and thus plays an important role in sustaining natural enemy populations and fostering improved pest control ( Jamont et al 2013 ; Russell 2015 ). Extrafloral nectar (EFN) production in cotton, which occurs on leaves and external parts of reproductive structures, sustains natural enemies ( Wäckers and Bonifay 2004 ; Hagenbucher et al 2013 ).…”

The “attract and reward” strategy of biological crop pest control takes advantage of a pest-damaged plant’s ability to produce odors as ‘distress signals’ to attract beneficial insects, and then reward these insects with excessive nectar production. Our study investigated the effects of a plant-produced chemical that initiates plant defense responses. Our results showed that despite increased plant odor and nectar production, application of the chemical did not affect beneficial pest insects. Overall, treatment of cotton with the plant chemical affected the plants, but not the pest or beneficial insects. Much remains to be learned before crop plants can be manipulated to enhance pest control.

“…Accordingly, an understanding of how to select the ideal nectar‐providing plant to enhance natural enemies has become an important topic of theoretical and empirical research . Predicting success based on traits is useful to generate generalizable rules that might avoid the need to experimentally evaluate a large number of candidate plant species that may be of potential use in a crop‐pest‐parasitoid system . A previous meta‐analysis of flowering plants used a taxonomic approach to show that the best nectar plants for prolonging parasitoid longevity are from the Apiaceae, Boraginaceae, Brassicaceae, Polygonaceae, Rosaceae, and Solanaceae .…”

More especially, that knowledge does not provide predictive power to determine which types of plants (especially in terms of traits) Figure 6.…”

BACKGROUND Ecosystem services are key to human survival. In agriculture, they offer potential to intensify production while reducing reliance on hazardous inputs, including pesticides. Nectar plants can nourish natural enemies of pests and thereby promote the ecosystem service of biological control. To date, however, the selection of optimal plants has been reliant on laborious testing of multiple candidate species for use in each new agroecosystem. We report a hybrid meta‐analysis of published literature, employing Bayesian network analysis. RESULTS The hybrid meta‐analysis identified the particular plant and parasitoid traits that were most predictive of promoted or suppressed parasitoid longevity. Integrating trait effects identified a combination of plant‐parasitoid traits that had the highest impact on parasitoid longevity: compound umbel or raceme inflorescence form and shallow corolla, together with high potential fecundity of the parasitoid. CONCLUSION Unlike earlier analyses focusing on taxonomic categories, we analyzed effect sizes in relation to the ecological traits of parasitoids and plants. This generated the first generalizable guidelines for selecting nectar plants as well as appropriate parasitoid targets for the enhancement of biological control. Within the guidelines, optimal outcomes resulted when plants with compound umbel or raceme inflorescences and shallow corollas were combined with fecund parasitoids. More widely, this type of ecological trait‐based meta‐analysis opens a new avenue for optimizing the delivery of other types of ecosystem services. © 2019 Society of Chemical Industry

“…In the field, flowering plants may also host alternative prey, which would support both larval development and adult fecundity. Flowering plants can enhance the effectiveness of natural enemies by increasing natural enemies' longevity, fecundity, and predation or parasitism rates (Lee and Heimpel, 2008;Russell, 2015;van Rijn and Wäckers, 2016), and have been widely used in conservation biological control (Fiedler et al, 2008;Haaland et al, 2011). Addison et al (2000) found pollen to be abundant on apple leaves very soon after the leaves had opened, and predatory mites can use windborne pollen released from cover crops in the field (Warburg et al, 2018).…”

“…Flowering plants have been widely used in conservation biological control (Fiedler et al, 2008;Haaland et al, 2011), and can increase natural enemies' longevity, fecundity, and predation or parasitism rates, which in turn can enhance the effectiveness of natural enemies as biocontrol agents (Lee and Heimpel, 2008;Russell, 2015;van Rijn and Wäckers, 2016). The role of pollen and nectar is well studied for hymenopteran parasitoids (e.g., Winkler et al, 2009;Russell, 2015), but increasing attention is being given to the role of non-prey food for predator fitness components such as survival or reproduction, involving studies on coccinellids (Bertolaccini et al, 2008), neuropterans (Resende et al, 2017), predatory mites (Khodayari et al, 2013;Khanamani et al, 2016;Riahi et al, 2017), spiders (Pollard et al, 1995;Nyffeler et al, 2016), and syrphids (van Rijn and Wäckers, 2016). Sugar feeding can improve fitness and performance, as well as nutritional status in coccinellids (Lundgren and Seagraves, 2011;Seagraves et al, 2011).…”

A Floral Diet Increases the Longevity of the Coccinellid Adalia bipunctata but Does Not Allow Molting or Reproduction

Adalia bipunctata L. (Coleoptera: Coccinellidae) is a generalist aphidophagous coccinellid and an important natural enemy in many agroecosystems including orchards. Coccinellid species have been observed to consume non-prey food like nectar and pollen, but the value of these foods for A. bipunctata is poorly known. The objective of this study was to determine the effect of different prey and non-prey diets on A. bipunctata larval development and adult longevity and fecundity. Larval development was studied on three prey diets: The aphids Dysaphis plantaginea and Myzus persicae and Lepidopteran eggs of Ephestia kuehniella; five flower diets: Matricaria chamomilla, Daucus carota, Fagopyrum esculentum, Anethum graveolens, and Sinapis alba; four pollen diets from three plant species: Typha angustifolia, Malus pumila (two varieties) and A. graveolens; and 1 M solutions of three sugars: glucose, fructose, and sucrose. Adult longevity and fecundity were tested on one prey diet (E. kuhniella eggs), three flower diets (F. esculentum, A. graveolens, and S. alba); the same four pollen diets and three sugar diets with larvae; and finally a mixed diet of sucrose and A. graveolens pollen. A water-only (starvation) control was used for both larval development and adult longevity and fecundity. Adult lipid content was assessed as a measure of how non-prey food affects the ladybeetles' nutritional status. Larvae did not develop beyond the first instar on any of the non-prey diets, but they lived more than twice as long as on F. esculentum and sugar diets than on water. Sugar and flower diets improved A. bipunctata adult longevity (71-92 days and 10-66 days, respectively) over a pure pollen diet (6-7 days). Fecundity was nil on all non-prey diets, and within a normal range on E. kuhniella eggs. The results suggest that pure floral diets do not support A. bipunctata molting or reproduction, but flowering plants can prolong A. bipunctata larval survival and adults longevity considerably when prey are absent. Adults on sugar diets had high lipid content, indicating that sugar feeding can improve overwintering survival. The findings could be used in agroecosystem design, such as the composition of flower strips for optimal functional diversity.
