Background: Crusted scabies (Norwegian scabies), a rare variant of scabies infestation, typically manifests in immunocompromised hosts or institutionalized patients with characteristic hyperkeratosis and fissured plaques. In AIDS patients with concurrent opportunistic infections like talaromycosis, scabies diagnosis may be obscured by overlapping cutaneous manifestations, potentially delaying appropriate management. This case highlights the diagnostic challenges in differentiating crusted scabies from treatment-refractory dermatitis in advanced HIV patients.

Background: The decline in pest control efficacy due to insecticide resistance remains a significant threat to global food security. While RNA interference (RNAi)-mediated silencing of key resistance genes offers a promising strategy to mitigate this challenge, and field-applicable targeting insecticide resistance remains limited. This study aimed to develop an RNAi-based spray platform utilizing fusion dsRNA to restore the efficacy of insecticides.

Mounting evidence indicates that symbionts play a beneficial role through secondary metabolic compounds and various chemical processes in host adaptation to adversity, particularly in herbivorous insects whose survival is severely threatened by insecticides or secondary metabolite stress. Despite extensive research on insect symbionts, the spread of these beneficial symbionts and the correlation with host phenotypes limit our ability to predict and manage the adaptive capabilities of insect populations in changing environments. In this review, we propose the concept of "Mobile Resistance Elements (MRE)" to describe the dynamic and adaptable nature of resistance-related symbionts that can be transmitted between insect hosts.

Understanding the insecticide resistance mechanisms and their underlying regulatory pathways is essential for pest management. Previous findings indicated that the overexpression of P450 gene, CYP6ER1, was a key mechanism for sulfoxaflor metabolic resistance in Nilaparvata lugens. However, it remains unclear whether quantitative changes in the target nicotinic acetylcholine receptors (nAChRs) contribute to sulfoxaflor resistance and the underlying regulatory mechanisms involved.

Article Synopsis
  • Facultative vertically transmitted symbionts are common in insects and can significantly influence their characteristics, but studying them is challenging due to difficulties in culturing these microbes and a lack of genetic tools.
  • Research on the brown planthopper (Nilaparvata lugens) revealed that a specific symbiont, Ca. Arsenophonus nilaparvatae, can be cultured and its entire genome sequenced, demonstrating its role in increasing the insect's susceptibility to insecticides.
  • The study also showed that this symbiont could be passed down to offspring, impacting the host's detoxification system, which has important implications for pest control and insecticide application strategies.

Article Synopsis
  • The study explores how the RNA interference (RNAi) efficiency of double-stranded RNA (dsRNA) in feeding Nilaparvata lugens (a type of insect) is hindered by a specific endonuclease enzyme found in their gut.
  • Researchers identified a gene for this endonuclease, which is significantly active in the early development stages of the insect and suggests it disrupts oral RNAi when dsRNA is fed.
  • The findings indicate that the presence of this endonuclease reduces the stability of dsRNA in the gut, highlighting a potential target for improving RNAi strategies in managing insect pests like N. lugens.
