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 The Pyralidae, commonly called pyralid moths, snout moths or grass moths, are a family of Lepidoptera in the ditrysian superfamily Pyraloidea. In many (particularly older) classifications, the grass moths (Crambidae) are included in the Pyr ... 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 stembore ...

Tomato Stemborer
The South American potato tuber moth, Andean potato tuber moth or tomato stemborer (''Symmetrischema tangolias'') is a moth of the family Gelechiidae. It is native to South America, but has become a pest worldwide. Records include North America, Australia and New Zealand. Species Description Tomato stemborer eggs are shaped oval and have a size of 0.7 x 0.4 mm for a freshly laid egg. The colouration changes to orange-yellow when the eggs start to develop and turn to dark gray before hatching. However, there is not much known about the caterpillar stage on tomato stemborer. Adult moths typically lay their eggs on invaded plants during nighttime. The larva is typically slender and cylindrical with pinkish, dark head capsule and segments are distinct; caterpillar has small, bristle-like structures on its body. The pupal stage occurs within a cocoon, with dark brown colouration encased in a protective shell. The adult moth has distinctive black triangle patches along the lateral mar ...

Sesamia
''Sesamia'' is a genus of moths of the family Noctuidae erected by Achille Guenée in 1852.

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-el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crambidae
Crambidae comprises the grass moth family of lepidopterans. They are variable in appearance, with 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 that 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.

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.

It is a widespread species, known from Iran, India, Sri Lanka, China, eastern Asia, Japan, Taiwan, Malaysia to the Pacific. It is a serious pest of rice.
