The European corn borer (Ostrinia nubilalis), also known as the European corn worm or European high-flyer, is a moth of the family Crambidae. It is a pest of grain, particularly maize ( Zea mays ). The insect is native to Europe, originally infesting varieties of millet , including broom corn .
Sesamia nonagrioides, the Mediterranean corn borer, pink stalk borer or West African pink borer, is a moth of the family Noctuidae. It was described by Alexandre Louis Lefèbvre de Cérisy in 1827. It is found in Spain , southern France , Italy and on the Balkan Peninsula , as well as in north-western, south-western and western Africa .
The Asian corn borer, Ostrinia furnacalis, is one of the biggest pests of maize in Asia, causing 10%-30% of yield losses in the field, and in some cases up to 80% yield loss. [7] These pests carry fungal pathogens (such as Bipolaris maydis and Curvularia lunata ) which cause diseases such as maydis leaf blight and curvularia leaf spot in the crop.
It was described by Achille Guenée in 1854 and is known by the common name Asian corn borer since this species is found in Asia and feeds mainly on corn crop. The moth is found from China to Australia , including in Java, Sulawesi, the Philippines, Borneo, New Guinea, the Solomon Islands, and Micronesia.
"Push-pull" experimental plots at ICIPE campus in Mbita, Kenya. (Left: Maize with Desmodium spp. intercropping. Right: Maize monoculture with Striga infestation).. Push–pull technology is an intercropping strategy for controlling agricultural pests by using repellent "push" plants and trap "pull" plants. [1]
When the daily dose was raised to 9 mg for 57 days, a reversible inhibition of blood cholinesterase was found. In table 1 some LD 50 values for various non-human species are listed. Table 1: LD 50 values of EPN for different routes of exposure administered to various organisms. All data was derived from 16

Another method of prevention is to leave land fallow for 2 months especially where maize is produced using irrigation. It is also recommended to plough and expose soil to sunlight for at least 2 months. [7] MLN resistance is an important trait to maize breeders. [9] Forward genetics is increasingly being used. [9]
