A larva of Helicoverpa armigera, the world's worst insect pest

Top
Scientists from CSIRO and elsewhere are working to sequence the genome of the Helicoverpa armigera moth, the world's worst insect pest of crops. This moth causes $225 million of damage a year in Australia – $5 billion globally – to crops such as cotton, legumes and vegetables.

This moth is resistant to nearly every class of chemical pesticide and threatens the long-term viability of transgenic crops which are reliant on the biological pesticide Bacillus thuringiensis (Bt).

The sequencing of the genome will greatly facilitate this research by improving the power, cost-effectiveness and insights from the genetic work on this species and its American cousin H. zea.
