Insect pests include: [1]
The larvae of several insect species, primarily belonging to the orders Coleoptera, Lepidoptera, Diptera, and Hemiptera, as well as Orthoptera adults, are persistent pearl millet pests in the Sahel. [3] [4] [5] The following pest species are reported for northern Mali. [6] [7]
Grasshoppers that frequently attack millets in the Dogon country of Mali are Oedaleus senegalensis , Kraussaria angulifera , Cataloipus cymbiferus , and Diabolocatantops axillaris . [6]
In northern Ghana, Poophilus costalis (spittle bug) is reported as a millet pest, as well as Dysdercus volkeri , Heliocheilus albipunctella , Coniesta ignefusalis , and caterpillars of Amsacta moloneyi and Helicoverpa armigera . [9]
In northern Nigeria, heavy infestations of Hycleus species, including Hycleus terminatus (syn. Mylabris afzelli ), Hycleus fimbriatus (syn. Mylabris fimbriatus ), Hycleus hermanniae (syn. Coryna hermanniae ), and Hycleus chevrolati (syn. Coryna chevrolati ), have affected early plantings of pearl millet crops. [10]
In South India, pests include the shoot fly Atherigona approximata . [11]
In North America, regular pests include the chinch bug Blissus leucopterus . [12] [13] [14] [15] [16]
Panicum miliaceum is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. The crop is extensively cultivated in China, India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the United States, where about half a million acres are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet. Proso millet is a relative of foxtail millet, pearl millet, maize, and sorghum within the grass subfamily Panicoideae. While all of these crops use C4 photosynthesis, the others all employ the NADP-ME as their primary carbon shuttle pathway, while the primary C4 carbon shuttle in proso millet is the NAD-ME pathway.
Eleusine coracana, or finger millet, also known as ragi in India, kodo in Nepal,and "kurakkan" in Sri Lanka is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Africa and Asia. It is a tetraploid and self-pollinating species probably evolved from its wild relative Eleusine africana.
Crambidae comprises the grass moth family of lepidopterans. They are variable in appearance, with the nominal subfamily Crambinae taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects that rest in wing-spread attitudes.
Pearl millet is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity, and suggested area of domestication, for the crop is in the Sahel zone of West Africa. Recent archaeobotanical research has confirmed the presence of domesticated pearl millet on the Sahel zone of northern Mali between 2500 and 2000 BC. 2023 is the International Year of Millets, declared by the United Nations General Assembly in 2021.
Foxtail millet, scientific name Setaria italica, is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most grown millet species in Asia. The oldest evidence of foxtail millet cultivation was found along the ancient course of the Yellow River in Cishan, China, carbon dated to be from around 8,000 years before present. Foxtail millet has also been grown in India since antiquity.
Echinochloa frumentacea is a species of Echinochloa. Both Echinochloa frumentacea and E. esculenta are called Japanese millet. This millet is widely grown as a cereal in India, Pakistan, and Nepal. Its wild ancestor is the tropical grass Echinochloa colona, but the exact date or region of domestication is uncertain. It is cultivated on marginal lands where rice and other crops will not grow well. The grains are cooked in water, like rice, or boiled with milk and sugar. Sometimes it is fermented to make beer. While also being part of staple diet for some communities in India, these seeds are, in particular, eaten during religious fasting. For this reason, these seeds are commonly also referred to as "vrat ke chawal" in Hindi. Other common names to identify these seeds include oodalu (ಊದಲು) in Kannada, Shyamak (শ্যামাক) or Shyama Chal in Bangla, jhangora in the Garhwal Hills, bhagar (भगर) in Marathi-speaking areas, samo or morio seeds in Gujarati, or kuthiraivaali (குதிரைவாளி) in Tamil.
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa.
Blissus leucopterus, also known as the true chinch bug, is a small North American insect in the order Hemiptera and family Blissidae. It is the most commonly encountered species of the genus Blissus, which are all known as chinch bugs. A closely related species is B. insularis, the southern chinch bug.
Paspalum scrobiculatum, commonly called Kodo millet or Koda millet, is an annual grain that is grown primarily in Nepal and also in India, Philippines, Indonesia, Vietnam, Thailand, and in West Africa from where it originated. It is grown as a minor crop in most of these areas, with the exception of the Deccan plateau in India where it is grown as a major food source. It is a very hardy crop that is drought tolerant and can survive on marginal soils where other crops may not survive, and can supply 450–900 kg of grain per hectare. Kodo millet has large potential to provide nourishing food to subsistence farmers in Africa and elsewhere.
Panicum sumatrense, known as little millet, is a species of millet in the family Poaceae.
Dogon country is a region of eastern Mali and northwestern Burkina Faso populated mainly by the Dogon people, a diverse ethnic group in West Africa with diverse languages. Like the term Serer country occupied by the Serer ethnic group, Dogon country is vast, and lies southwest of the Niger River belt. The region is composed of three zones: the plateau, the escarpment and the Seno-Gondo plain.
Hycleus is a genus of blister beetle belonging to the Meloidae family found in Africa and Asia. The genus contains over 400 species, which historically have been confused with the genus Mylabris.
Coniesta ignefusalis, the pearl millet stem-borer, is a moth in the family Crambidae. It was described by George Hampson in 1919.
A stemborer is any insect larva, or arthropod, that bores into plant stems. However the term most frequently refers among the Coleoptera to the larva of certain longhorn beetles such as Dorysthenes buqueti and those of the genus Oberea, and among the Lepidoptera to certain moths of the Crambidae, Castniidae, Gelechiidae, Nolidae, and Pyralidae families.
Geromyia penniseti, the millet grain midge, is a species of gall midge in the family Cecidomyiidae. It is found in Africa and South Asia. During the rainy season, it feeds on the developing grains of pearl millet plants.
Sesamia calamistis, the African pink stem borer, is a moth of the family Noctuidae.
Atherigona approximata, the pearl millet shoot fly, is a species of fly in the family Muscidae. The larvae feed on the central growing shoots of crops such as pearl millet and sorghum. It is found in South Asia.
Stenodiplosis sorghicola, the sorghum midge, is a species of gall midge in the family Cecidomyiidae. It is a pest of millets. The species is native to Africa and is also found in India. During the rainy season, it feeds on the developing grains of pearl millet plants.
