“…IDseq has been used previously to successfully identified pathogens in CSF samples (21). Of the sequencing reads with an alignment length ≥30bp, only DNA or RNA of bacteriophages or plant or insect viruses were identified in the current study (31)(32)(33)(34)(35)(36)(37). Although a connection between unspecific immune response in humans with positive stool samples for a pepper associated virus has been suggested (38), it is largely presumed that plant and insect viruses do not cause clinical signs in mammals (39).…”

Meningoencephalitis of unknown origin (MUO) describes a group of meningoencephalitides in dogs with a hitherto unknown trigger. An infectious agent has been suggested as one possible trigger of MUO but has not been proven so far. A relatively new method to screen for viral RNA or DNA is next-generation sequencing (NGS) or deep sequencing. In this study, a metagenomics analysis of the virome in a sample is analyzed and scanned for known or unknown viruses. We examined fresh-frozen CSF of 6 dogs with MUO via NGS using a modified sequence-independent, single-primer amplification protocol to detect a possible infectious trigger. Analysis of sequencing reads obtained from the six CSF samples showed no evidence of a virus infection. The inability to detect a viral trigger which could be implicated in the development of MUO in the examined population of European dogs, suggests that the current techniques are not sufficiently sensitive to identify a possible virus infection, that the virus is already eliminated at the time-point of disease outbreak, the trigger might be non-infectious or that there is no external trigger responsible for initiating MUO in dogs.

“…The transmission and prevalence of SfMNPV is increased at higher temperatures, thus, climate change is likely to alter the dynamics of NPV disease in FAW populations in the future (Elderd & Reilly 2014). In contrast to the NPV, the granulovirus (genus Betabaculovirus) is less prevalent in natural populations of FAW and is far slower killing (Valicente 1989;Cuartas et al 2014;, Pidre et al 2019. The speed of kill by a baculovirus depends on the quantity of inoculum, larval instar, and temperature during the incubation period, and differs between the strains of FAW (Popham et al 2021).…”

The fall armyworm (FAW), Spodoptera frugiperda (JE Smith, 1797), is a serious pest of several crops, particularly maize and other cereals. It has long been known as a pest in the Americas and has invaded most of Africa and parts of the Middle East, Asia, and Australia in the last six years. Its new status as an invasive species causing serious damage in many regions worldwide has highlighted the need for better understanding and has generated much research. In this article, we provide a comprehensive review of FAW covering its (i) taxonomy, biology, ecology, genomics, and microbiome, (ii) worldwide status and geographic spread, (iii) potential for geographic expansion and quarantine measures in place, and (iv) management including monitoring, sampling, forecasting, biological control, biopesticides, agroecological strategies, chemical control, insecticide resistance, effects of insecticides on natural enemies, as well as conventional and transgenic resistant cultivars. We conclude with recommendations for research to enhance the sustainable management of FAW in invaded regions.

“…The symptoms are loss of appetite, lethargy, body sagging, softening of the integument, and a tendency to turn off color. Some viruses studied against S. frugiperda are Rhabdovirus (Sf-RV) [61]; granulovirus (SfGV ARG) type 1, 2, and 3 [62,63]; ascovirus (SfAV-1a) [64]; ichnovirus (HdIV) [65]; and the most studied, nucleopolyhedrovirus (SfMNPV) [55,66]. Undoubtedly, this strategy has shown high efficiency in the control of S. frugiperda in in vitro evaluations.…”

The strategies for controlling the insect pest Spodoptera frugiperda have been developing over the past four decades; however, the insecticide resistance and the remarkable adaptability of this insect have hindered its success. This review first analyzes the different chemical compounds currently available and the most promising options to control S. frugiperda. Then, we analyze the metabolites obtained from plant extracts with antifeedant, repellent, insecticide, or ovicide effects that could be environmentally friendly options for developing botanical S. frugiperda insecticides. Subsequently, we analyze the biological control based on the use of bacteria, viruses, fungi, and parasitoids against this pest. Finally, the use of sex pheromones to monitor this pest is analyzed. The advances reviewed could provide a wide panorama to guide the search for new pesticidal strategies but focused on environmental sustainability against S. frugiperda.
