Stemborer
A stemborer (stem borer) 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. Stem borers include: ;Coleoptera *Banana stemborer weevil ('' Cosmopolites sordidus'') * Coffee white stem borer (''Xylotrechus quadripes'') * Sugarcane longhorn stemborer (''Dorysthenes buqueti'') ;Lepidoptera *African pink stemborer (''Sesamia calamistis'') * African white stemborer (''Maliarpha separatella'') *Asiatic rice stemborer (striped rice stemborer, ''Chilo suppressalis'') * Banana stem borer (''Telchin licus'') * Egyptian stemborer (''Earias insulana'') *Gold-fringed rice stemborer (''Chilo auricilius'') *Pearl millet stem borer (''Coniesta ignefusalis'') *Spotted stem borer (''Chilo partellus'') * ...

Chilo Partellus
''Chilo partellus'', the spotted stalk borer or spotted stem borer, is a moth in the family Crambidae. It was described by Charles Swinhoe in 1885. It is found in India, Pakistan, Iran, Ethiopia, Lesotho, Madagascar, Malawi, South Africa, Sudan, Tanzania, Uganda and on Mayotte. ''C. partellus'' is a pest that was introduced to Africa most likely from India in the early 20th century. After arriving in Africa, it has spread to nearly all countries in eastern and southern Africa, and it is assumed that it is spreading to western Africa. ''C. partellus'' is indigenous to Asia and became established in eastern Africa in the early 1930s. ''C. partellus'' is one of the most economically damaging pests in Asia and Africa, attacking all parts of the plant except the roots. Habitat ''C. partellus'' has rapidly spread over a wide geographical range and has proven to be a very efficient colonizer and devastating pest wherever it may occur. In general, ''C. partellus'' occurs in low to mid- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crambidae
The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae (grass moths) taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects which rest in wing-spread attitudes. In many classifications, the Crambidae have been treated as a subfamily of the Pyralidae or snout-moths. The principal difference is a structure in the tympanal organs called the praecinctorium, which joins two tympanic membranes in the Crambidae, and is absent from the Pyralidae. The latest review by Munroe and Solis, in Kristensen (1999), retains the Crambidae as a full family. The family currently comprises 15 subfamilies with altogether 10,347 species in over 1,000 genera. Systematics *subfamilia incertae sedis **''Conotalis'' Hampson, 1919 **''Exsilirarcha'' Salmon & Bradley, 1956 *Subfamily Acentropinae Stephens, 1836 *Subfamily Crambinae Latreille, ...

Egyptian Stemborer
''Earias insulana'', the Egyptian stemborer, Egyptian bollworm, spiny bollworm or cotton spotted bollworm, is a moth of the family Nolidae. The species was first described by Jean Baptiste Boisduval in 1833. It is found in most of Africa, southern Europe, the Near East and Middle East, Japan, Taiwan, the Philippines, Australia and Hawaii. It is a rare in immigrant in Great Britain. The wingspan is 20–22 mm. Adults show strong seasonal polymorphism, depending on the temperature. Two distinct forms are present in some areas: a bright green summer form and a brownish-yellow autumn form. The larvae feed on okra, cotton and hibiscus, but have also been recorded on rice, sugarcane and corn. Initially, larvae tunnel into the buds of their host plant. Later, the larvae feeds on the bolls, which become brown and fall off. Secondary invasion by fungi and bacteria sometimes occurs. Full-grown larvae are 13–18 mm long and their wingspan is generally about 24–28 mm. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coniesta Ignefusalis
''Coniesta ignefusalis'', the pearl millet stem-borer, is a moth in the family Crambidae. It was described by George Hampson in 1919. Distribution ''Coniesta ignefusalis'' is found throughout the West African Sahel, including in Senegal, Mali, Burkina Faso, Ghana, Benin, and Nigeria, where the species is known by local farmers as a major pest of grain crops. Crop pest As a major grain crop pest in the Sahel, the larvae attack pearl millet, sorghum, and maize. It is the main pearl millet pest in Senegal.Ruparao T. Gahukar, Gadi V. P. Reddy.
