![]() Adults were fed Lablab purpureus and kept at 25 ± 1 ☌, 70 ± 5% relative humidity, and 14:10 light:dark cycle. Megalurothrips usitatus samples were collected from Wanning, Hainan province, and reared for approximately 100 generations in the laboratory. Sample preparation and genomic DNA sequencing The high-quality reference genome of the bean flower thrips obtained in this study will lay the foundation for future investigations on the ecology of thrips and provide valuable genetic information for its management. usitatus with those of other insects to explore the genomic signatures of resistance. usitatus using a combination of PacBio long read, Illumina short-read sequencing, and chromosome conformation capture (Hi-C) technologies. In this study, we assembled a chromosome-level genome of M. Filling this knowledge gap will benefit our efforts at pest control. Understanding the evolution of pesticide resistance is necessary for developing novel management strategies, but the genetics of M. However, excessive pesticide usage leaves residues that risk consumer health and also induce resistance in pest insects. Its small body size, cryptic behavior, and fast transmission present difficulties in pest control 6, 7.Īttempts to mitigate agricultural damage have largely involved chemical insecticides 8, 9, 10, 11, 12. ![]() The insect lays eggs in plant tissue and feeds on leaves, flowers and pods, causing economic losses worldwide, particularly in southern China, India, Japan, the Philippines, and Australia 1, 3, 5, 6. In conclusion, this high-quality genome provides an invaluable resource for us to understand the thrips’ ecology and genetics, contributing to pest management.īean flower thrips Megalurothrips usitatus is a highly harmful pest of leguminous crops in the genera Glycine, Arachis, and Vigna 1, 2, 3, 4. Comparative genomic analyses revealed that expanded gene families were enriched in fatty acid metabolism and detoxification metabolism (ABC transporters), and contracted gene families were strongly associated with chitin-based cuticle development and sensory perception of taste. The final genome was anchored into 16 pseudo-chromosomes containing 14,000 genes, of which 91.74% were functionally annotated. The assembled genome was 238.14 Mb with a scaffold N50 of 13.85 Mb. ![]() usitatus genome using a combination of PacBio long read and Hi-C technologies. Despite the importance of a genome in developing novel management strategies, genetic studies on M. Its small size allows for easy concealment, and large reproductive capacity easily leads to infestations. Bean flower thrips Megalurothrips usitatus is a staple pest of cowpea and other legumes and causes dramatic economic losses.
