Titre : Decoding gigantic insect genome could help tackle devastating locust crises

Résumé
A ’game changing’ study deciphering the genetic material of the desert locust could help combat the crop-ravaging behavior of the notorious insect pest which currently exacerbates a hunger crisis across many developing countries.

Descriptif
Desert locust swarms are a major economic issue in more than 65 countries, across more than 20 per centof the world’s total land surface. Authorities in affected countries have been carrying out aerial spraying of pesticides, but the scale of the infestation is often beyond local capacity as desert locusts can travel up to 150km (95 miles) in a day, crossing national borders and rugged terrain in regions with little road infrastructure.

While locust swarms are infamous for the great damage they inflict to agriculture, their genetic material (’genome’) is famed amongst researchers for its enormous size. At more than 8.8 billion base pairs of DNA (8.8 ’giga-bases’), the desert locust genome is the largest insect genome sequenced to date and over 2.8 times larger than the human genome.
