“…Other traits that may be important, such as the amount and quality of nectar, were data deficient so not included. The quality of nectar may also adversely affect parasitoids, such as the presence of melezitose which reduces some parasitic wasps' longevity and oviposition rate . Parasitoids may also avoid some nectars because of secondary compounds and antimicrobial proteins .…”

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

“…It was reported that honeydew volatiles are important kairomones for parasitoids and predators, and these volatiles can improve the efficacy of natural enemies (Almohamad et al, 2009;Leroy et al, 2011). Many studies have indicated that the composition of aphid honeydew obviously influences the performance of aphid enemies (Hogervorst et al, 2007;Hagenbucher et al, 2014;Tena et al, 2016;Zhou et al, 2016;Benelli et al, 2017). However, relatively few studies have evaluated the quantitative effects.…”

Ant–hemipteran association decreases parasitism of Phenacoccus solenopsis by endoparasitoid Aenasius bambawalei

1. Mutualism between ants and honeydew‐excreting hemipterans is ubiquitous in the ecosystem. It is widely accepted that ant tending facilitates the colony growth of hemipterans by protecting them from predators and parasitoids. However, few studies have explored how ant tending helps defend against natural enemies. 2. Ghost ant Tapinoma melanocephalum and the invasive mealybug Phenacoccus solenopsis have a close mutual relationship. Previous studies have shown that ghost ant tending can definitely reduce parasitism and visit frequency of Aenasius bambawalei, the dominant endoparasitoid of P. solenopsis. However, the ghost ant workers seldom attack the parasitoids. It is still unclear how the ghost ant adversely affects parasitoids. This study explored the mechanism underlying the impacts of ants on natural enemies of the mealybugs. 3. Honeydew produced by P. solenopsis was an attractant to A. bambawalei. Parasitoids exhibited less searching activity, shorter longevity and lower parasitism when supplied with less honeydew. Aenasius bambawalei showed significant avoidance of pygidial gland secretions and visual cues of ghost ants. Parasitism in plants treated with 6‐methyl‐5‐hepten‐2‐one, actinidine, and gland extracts was significantly lower than that in plants treated only with solvents (paraffin oil or double‐distilled water). 4. It is concluded that honeydew consumption by ghost ants could negatively influence the performance of parasitoids. The pygidial gland secretions and visual cues of ghost ants also significantly inhibit the parasitism. These results may contribute to a better understanding of the regulation mechanism in ant–hemipteran–enemy interactions.

“…This important finding has important implications for their effects on biological control in adjacent crops. Literature shows that increased reproductive lifespan enhances fecundity as well as host parasitism in general (Heimpel & Jervis, 2005;Benelli et al, 2017) as well as specifically for D. rapae (Tylianakis et al, 2004;Jamont et al, 2013), D. semiclausum (Yang et al, 1993;Winkler et al, 2006), and C. glomerata (Hasan & Ansari, 2010). The extent of longevity benefit to parasitoids varied depending on the flower species and interplay between flower species and parasitoid species.…”

Floral resources from native plants that are adapted to the local environment could be more advantageous than the use of nonnative plants. In Australia, there is a dearth of information on the benefits of native plants to natural enemies and their selectivity against pests. Accordingly, we examined the longevity of the parasitoids Diaeretiella rapae (McIntosh) and Cotesia glomerata (L.) (both Hymenoptera: Braconidae), and Diadegma semiclausum (Hellen) (Hymenoptera: Ichneumonidae) exposed to flowering shoots from Australian native plants which was compared with the nonnative buckwheat (Fagopyrum esculentum), often used in conservation biological control. Longevity of parasitoids was significantly enhanced by the Australian natives Westringia fruticosa, Mentha satureioides, Callistemon citrinus, Leptospermum cv. 'Rudolph', Grevillea cv. 'Bronze Rambler', Myoporum parvifolium, Lotus australis, and nonnative F. esculentum. The highest mean survival by native plant species was 3.49 higher for D. rapae with Leptospermum sp. and 4.39 higher for D. semiclausum with M. parvifolium. For C. glomerata, Grevillea sp. increased longevity by 6.99 compared with water only. Longevity of Plutella xylostella (L.) (Lepidoptera: Plutellidae), a major crop pest, was enhanced by all plants against which it was screened except Acacia baileyana, a species that had no effect on parasitoid longevity. Several Australian native plant species that benefit parasitoids were identified. None of the plant species provided a selective benefit to the parasitoid D. semiclausum compared with its host P. xylostella; however, the benefit of M. parvifolium and Grevillea sp. on the longevity of D. semiclausum was relatively higher compared with the pest. These results suggest the need for field studies to determine whether native Australian plants increase P. xylostella impact in nearby brassica crops.
