Army worms have been detected in Ghana's Upper East Region, according to news reports confirmed to IRIN by the FAO's Deputy Regional Representative for West Africa, George Mburathi.
News organisations have reported that some 130,000 ha of cereals are threatened by the caterpillars, which have also been detected in significant numbers in Cameroon.
Mburathi told IRIN that, as far as he knew, Ghana and Cameroon were the only two West African countries where the presence of the caterpillars, which reduce harvests by attacking crops before they mature, had been reported so far.
East and Central African countries such as Kenya, Sudan and Chad have already been attacked by the pest.
