My study interest is to evaluate the impact of environmental changes on the evolutionary history of organisms. The desert locust (Schistocerca gregari) is one of the most notorious migratory pests in the world, which would be an ideal model. Since the second half of last year, a transnational locust catastrophe of exceptional severity spreads across Africa and then moves towards Asia. The locust swarm has eaten the amount of food that can feed millions of people. Depending on the population density, the locusts can reflect two alternative phases: the long-living solitarious phase or the swarming gregarious phase. The gregarious phase can appear after hours of gathering and is soon consolidated to keep locust swarms together. During the process of phase change, many biological and phenotypic traits will be changed, including the body color, morphology, behavior, immune responsiveness. We sequenced the first genome of the desert locust, comprising 8.8 Gbp. We still lack the knowledge about which mechanisms affect the locust swarming behavior, a social experience, and the effective measures to disband locust swarms by disrupting the consolidated swarming behavior. Thus, I try to use the desert locust genome, transcriptomic and epigenetic data of the two transformation phases to generate a broad comparative genomics framework to study the biological and phenotypic changes during the transformation.

    Background: At the time of publication, the most devastating desert locust crisis in decades is affecting East Africa, the Arabian Peninsula and South-West Asia. The situation is extremely alarming in East Africa, where Kenya, Ethiopia and Somalia face an unprecedented threat to food security and livelihoods. Most of the time, however, locusts do not occur in swarms, but live as relatively harmless solitary insects. The phenotypically distinct solitarious and gregarious locust phases differ markedly in many aspects of behaviour, physiology and morphology, making them an excellent model to study how environmental factors shape behaviour and development. A better understanding of the extreme phenotypic plasticity in desert locusts will offer new, more environmentally sustainable ways of fighting devastating swarms. Methods: High molecular weight DNA derived from two adult males was used for Mate Pair and Paired End Illumina sequencing and PacBio sequencing. A reliable reference genome of Schistocerca gregaria was assembled using the ABySS pipeline, scaffolding was improved using LINKS. Results: In total, 1,316 Gb Illumina reads and 112 Gb PacBio reads were produced and assembled. The resulting draft genome consists of 8,817,834,205 bp organised in 955,015 scaffolds with an N50 of 157,705 bp, making the desert locust genome the largest insect genome sequenced and assembled to date. In total, 18,815 protein-encoding genes are predicted in the desert locust genome, of which 13,646 (72.53%) obtained at least one functional assignment based on similarity to known proteins. Conclusions: The desert locust genome data will contribute greatly to studies of phenotypic plasticity, physiology, neurobiology, molecular ecology, evolutionary genetics and comparative genomics, and will promote the desert locust’s use as a model system. The data will also facilitate the development of novel, more sustainable strategies for preventing or combating swarms of these infamous insects.
