Locusts have formed plagues since prehistory. Pergamon Press, New York, pp. During the last two millennia, locust plagues continued to appear at irregular intervals with the main recorded outbreaks of the desert and migratory locusts occurring in Africa, the Middle East, and Europe. We also demonstrate that a subset of locust genes display evidence of historical methylation within their protein encoding sequences. Several cultures throughout the world consume insectsand locusts are considered a delicacy and eaten in many African, Middle Eastern, and Asian countries. A short-winged morph, whose occurrence is controlled by a simple recessive Mendelian unit, was recently discovered in Locusta migratoria. The rain allowed swarms to develop and move north to Morocco and Algeria, threatening croplands. SATO T. Finer scale mapping may reveal biologically meaningful heterogeneity in the methylomes of solitarious versus gregarious locusts.

    They form bands of wingless nymphs which later become swarms of winged adults.

    Phenotypic Plasticity of Insects: Mechanisms and Consequences. In agreement with the L. Together with the finding that the cabbage moth Mamestra brassicae possesses relatively high levels of DNA methylation [19]these results highlight the variability in the amount of methylation present among insect genomes, the majority of which have been shown to be sparsely methylated to date.

      Until very recently, there was only one report of DNA methylation in locusts, with estimates of methylcytosine content obtained using a rudimentary paper chromatography technique [31]. In the spring of locusts arrived outside Damascus eating the majority of the crops and vegetation of the surrounding countryside.
