New volvovirus isolate from Thai domesticated house cricket, Acheta domesticus (Orthoptera: Gryllidae)
This study investigated the genomic characteristics of Acheta domesticus volvovirus (AdVVV) in a commercial cricket farming operation. BLAST analysis of the Acheta domesticus genome assembly identified sequences with high similarity to the AdVVV-Japan genome, suggesting AdVVV presence. PCR confirmed AdVVV infection in the A. domesticus breeding population from Nakhon Ratchasima farm, Thailand. The complete 2,516 nucleotide AdVVV-Thailand genome was reconstructed through targeted primer amplification and sequencing. It contained four open reading frames encoding hypothetical proteins, with a characteristic hairpin structure at the termini, consistent with other AdVVV isolates. Phylogenetic analysis revealed AdVVV-Thailand’s closer genetic affiliation with AdVVV-Japan compared to other isolates. Comparative analysis of coding sequences across five AdVVV isolates showed the highest variability in the hypothetical protein/putative capsid protein ORF1, with 64 variable sites out of 1086 bases, suggesting its significance in genetic diversity. In contrast, ORF2, ORF3, and ORF4 exhibited minimal variability. The majority of variations were singletons, with 85.33% confined to ORF1. This study confirmed AdVVV presence in a commercial cricket farm, reconstructed the AdVVV-Thailand genome, provided insights into its phylogeny and genetic diversity across isolates, highlighting the putative capsid protein’s role in driving variability. These findings enhance understanding of AdVVV genomics and evolutionary dynamics within cricket populations.
期刊介绍：
The Journal of Insects as Food and Feed covers edible insects from harvesting in the wild through to industrial scale production. It publishes contributions to understanding the ecology and biology of edible insects and the factors that determine their abundance, the importance of food insects in people’s livelihoods, the value of ethno-entomological knowledge, and the role of technology transfer to assist people to utilise traditional knowledge to improve the value of insect foods in their lives. The journal aims to cover the whole chain of insect collecting or rearing to marketing edible insect products, including the development of sustainable technology, such as automation processes at affordable costs, detection, identification and mitigating of microbial contaminants, development of protocols for quality control, processing methodologies and how they affect digestibility and nutritional composition of insects, and the potential of insects to transform low value organic wastes into high protein products. At the end of the edible insect food or feed chain, marketing issues, consumer acceptance, regulation and legislation pose new research challenges. Food safety and legislation are intimately related. Consumer attitude is strongly dependent on the perceived safety. Microbial safety, toxicity due to chemical contaminants, and allergies are important issues in safety of insects as food and feed. Innovative contributions that address the multitude of aspects relevant for the utilisation of insects in increasing food and feed quality, safety and security are welcomed.
