Every increase in one degree of global warming will increase losses of crops to insects from 10% to 25%.
Plant diseases require as much attention now as ever to ensure that food systems are in place in the next season. There are also serious implications for forestry and the environment more broadly.
Biological control uses live organisms to kill or eat the pest insects.
Countries should promote alternatives to pesticides and more carefully examine how to prevent insect invasions in the first place
The rice-eating fall armyworm has spread across Asia in a year and is now found in half the provinces of China.
Farmers should use biopesticides - naturally occurring substances that kill pests such as the fall armyworm - instead of using pesticides, which are often highly toxic.
Big data can be used to properly advise smallholder farmers in Africa and help guide pest monitoring efforts.
The Fall armyworm will remain in Africa for a long time unless concerted action is taken.
Many alien plants and animals have been introduced to Africa from other regions and spread from country to country, often having devastating effects.
Fall armyworms have a number of characteristics that make them particularly hard to control. They are strong fliers, can breed at a high rate and also develop quick resistance to pesticides.
