“…Sucrose, fructose, and glucose are common saccharides in most nectars. − A few nectars also contain lower levels of disaccharides, such as maltose and melibiose as well as trace levels of oligosaccharides such as raffinose, melezitose, and stachyose Camellia oleifera nectar, pollen, and honey contained a high level of raffinose and stachyose compared with B.…”

Identifying the components of Camellia oleifera honey and pollen and conducting corresponding toxicological tests are essential to revealing the mechanism of Camellia oleifera toxicity to honey bees. In this research, we investigated the saccharides and alkaloids in honey, nectar, and pollen from Camellia oleifera, which were compared with honey, nectar, and pollen from Brassica napus, a widely planted flowering plant. The result showed that melibiose, manninotriose, raffinose, stachyose, and lower amounts of santonin and caffeine were found in Camellia oleifera nectar, pollen, and honey but not in B. napus nectar, pollen, and honey. Toxicological experiments indicated that manninotriose, raffinose, and stachyose in Camellia oleifera honey are toxic to bees, while alkaloids in Camellia oleifera pollen are not toxic to honey bees. The toxicity mechanism of oligosaccharides revealed by temporal metabolic profiling is that oligosaccharides cannot be further digested by honey bees and thus get accumulated in honey bees, disturbing the synthesis and metabolism of trehalose, ultimately causing honey bee mortality.

“…Diverse agro-ecosystems impart numerous benefits to growers depending on location, 35 and while alyssum intercropping did not seem to confer benefits to strawberries in terms of pest management, several studies have demonstrated intercropping as an effective means of mitigating crop losses to pests, including alyssum for aphid control and buckwheat for control of a mirid pest. 3,20,26 Sweet alyssum may have potential as a control option for more late-season berry crops (i.e., blackberry), once parasitoid populations are more well-established. Our results highlight a need for scientists and growers to carefully consider the linked phenologies of pests, natural enemies, crops, and intercrops to deploy biodiversity-based strategies of pest management more effectively.…”

“…18 Various studies have demonstrated the ability for supplementary floral resources to enhance the survival and activity of parasitic hymenopterans like L. japonica and G. brasiliensis. 19,20 However, to accurately assess the potential efficacy of these parasitoids for control of D. suzukii, information about their population dynamics will be particularly important. 21 If they are to be effective, the populations must reach adequate levels for control during the period where D. suzukii is causing damage or else the phenological mismatch could render them ineffective for damage control.…”

BACKGROUND: The spotted wing drosophila, Drosophila suzukii Matsumura, is a South-East Asian vinegar fly that is a serious worldwide economic threat to the small fruit industry. Typical control consists of weekly pesticide applications, which can have nontarget effects, increase residual pesticides and lead to the development of resistance within pest populations. One potential alternate method of control is the planting of aromatic intercrops to attract the natural enemies of D. suzukii and/or repel the flies directly. We intercropped strawberry rows with flowering sweet alyssum or ryegrass-clover (control) to evaluate their efficacy at mitigating D. suzukii infestation through the attraction of two specialized larval parasitoids, Leptopilina japonica (Novkovic and Kimura) and Ganaspis brasiliensis (Ihering).RESULTS: Our study did not demonstrate any significant effect of sweet alyssum intercropping on the infestation rate of D. suzukii in strawberries or parasitism level. However, we found that advanced sampling date and recorded numbers of D. suzukii larvae and parasitoids were positively correlated, indicating higher populations at the end of the strawberry-growing season.CONCLUSIONS: Sweet alyssum intercrops did not reduce D. suzukii infestation rates or increase parasitism levels, likely due to low population numbers in early season berry varieties. Aromatic intercrops may be more effective for increasing pest control in later season crops.

BACKGROUNDNectar plants provide extra nourishment for parasitoids, which can utilize floral volatiles to locate nectar‐rich flowers. A promising strategy is to screen potential floral species based on the wasps' olfactory preferences for nectar sources, and to ensure their suitability for both natural enemies and targeted pests. Cotesia vestalis (Haliday) is a dominant parasitoid of the oligophagous pest Plutella xylostella, which poses a significant threat to cruciferous vegetables globally. However, the chemical cues in plant–parasitoid complexes mediating Cotesia vestalis to locate nectar food resources and the positive effect of nectar plants on the Cotesia vestalis population are poorly understood.RESULTSThe results showed that Fagopyrum esculentum was the most attractive plant that attracted Cotesia vestalis, not Plutella xylostella in 44 flowering plants from 19 families. 1,2‐Diethyl benzene and 1,4‐diethyl benzene, identified from the floral volatiles from F. esculentum in full bloom, were found to elicit dose‐dependent electrophysiological responses and attract Cotesia vestalis adults, demonstrating their potential as semiochemicals. Moreover, the age‐stage, two‐sex life table revealed that feeding on nectar food increased the efficacy of Cotesia vestalis adults against Plutella xylostella.CONCLUSIONIn summary, the findings provide insights into the chemical ecology of plant–parasitoid complexes and support the potential use of F. esculentum as insectary plants in habitat manipulation against Plutella xylostella by supplying natural nectar food for the Cotesia vestalis population. Our results suggest an attract and reward strategy based on an attractant for Cotesia vestalis to control Plutella xylostella, or the development of volatile‐based artificial food for Cotesia vestalis. © 2023 Society of Chemical Industry.
