“…Nevertheless, due to difficulties in rearing and maintaining the target Scarabaeidae beetles in laboratory conditions, we used the white spotted flower chafer, Protaetia brevitarsis as an insect model in the present study. This species is widely distributed in Korea, Japan, China, Taiwan and some parts of Europe [11,12]. Its life cycle comprises the embryo, larva, pupa, and imago stages, of which the larval stage is the longest and is the stage when the insect feeds and stores energy for the rest of the life cycle [13].…”

“…Depending on habitat conditions, adults can be observed in Korea from May to October with greatest abundance in July. They are gregarious and diurnal insects that overwinter as third instar larvae in the soil [11]. Herein, we described an isolate of M. anisopliae and characterized its insecticidal potential against the white-spotted flower chafer in laboratory conditions.…”

Root-feeding Scarabaeidae, particularly white grubs are considered among the most harmful coleopteran insect pests in turfgrass. In this work, sixteen entomopathogenic fungal species were assayed against flower chafer beetle, Protaetia brevitarsis (Coleoptera: Scarabaeidae) and Metarhizium anisopliae JEF-314 showed high virulence. The control ability of the isolate JEF-314 has been in detail tested for a model insect flower chafer beetle. Further analyses showed insect stage-dependent virulence where the fungal virulence was the highest against smaller instar larvae. Additionally, we confirmed that millet-based solid cultured granule was effective against the soil-dwelling larval stage. The isolate also showed a similar ability for a representative pest (Popillia spp.) in laboratory conditions. Our results clearly suggest a high potential of M. anisopliae JEF-314 to control the flower chafer beetle, possibly resulting in controlling of root-feeding white grubs in turfgrass. Based on the insect life cycle and susceptibility to the fungus, late spring and summer time would be the optimum time to apply JEF-314 granules for an effective control. Further characterization of the efficacy of the fungus under field conditions against the Scarabaeidae beetles might provide an efficient tool to control this beetle in an environment-friendly way.

White-spotted flower chafer (Protaetia brevitarsis) is an edible insect and P. brevitarsis larvae are used in traditional Oriental medicine. However, the molecular mechanisms behind the anti-inflammatory action of P. brevitarsis larvae are unknown. We investigated the effects of P. brevitarsis larvae ethanol extract (PBLE) on the inflammatory response as well as the molecular mechanisms underpinning this effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. PBLE effectively inhibited the synthesis of nitric oxide (NO) through inducible NO synthase (iNOS) and cyclooxygenase 2 protein expression and 20 μM PBLE suppressed the expression of pro-inflammatory cytokines, including interleukin (IL)-6 and IL-8, at a dose of. Further investigation of the mechanisms revealed that PBLE attenuated phosphorylation of nuclear factor kappa B (NF-κB) inhibitor alpha (IκB-α) and NF-κB p65 and interfered selectively with extracellular signal-regulated kinase (ERK)1/2 and p38 phosphorylation. These findings provide the first molecular basis that PBLE could be a potential candidate for attenuating proinflammatory NO induction via selective inhibition of the NF-κB, ERK, and p38 mitogen-activated protein kinase signalling pathways. It is necessary to verify the anti-inflammatory action of PBLE and to ascertain the related mechanisms, both in in vivo models and in clinical studies, to enable the application of PBLE as a potential therapeutic agent for inflammatory diseases.
