Fall Armyworm
The fall armyworm (''Spodoptera frugiperda'') is a species in the order Lepidoptera and one of the species of the fall armyworm moths distinguished by their larval life stage. The term "armyworm" can refer to several species, often describing the large-scale invasive behavior of the species' larval stage. It is regarded as a pest and can damage and destroy a wide variety of crops, which causes large economic damage. Its scientific name derives from ''frugiperda,'' which is Latin for ''lost fruit'', named because of the species' ability to destroy crops. Because of its propensity for destruction, the fall armyworm's habits and possibilities for crop protection have been studied in depth. It is also a notable case for studying sympatric speciation, as it appears to be diverging into two species currently. Another remarkable trait of the larva is that they consistently practice cannibalism, despite its fitness costs. The fall armyworm is active at a different time of year from th ...

African Armyworm
The African armyworm (''Spodoptera exempta''), also called ''okalombo'', ''kommandowurm'', or nutgrass armyworm, is a species of moth of the family Noctuidae. The larvae often exhibit marching behavior when traveling to feeding sites, leading to the common name "armyworm". The caterpillars exhibit density-dependent polyphenism where larvae raised in isolation are green, while those raised in groups are black. These phases are termed ''solitaria'' and ''gregaria'', respectively. ''Gregaria'' caterpillars are considered very deleterious pests, capable of destroying entire crops in a matter of weeks. The larvae feed on all types of grasses, early stages of cereal crops (e.g., corn, rice, wheat, millet, sorghum), sugarcane, and occasionally on coconut. The ''solitaria'' caterpillars are less active and undergo much slower development. The species is commonly found in Africa, but can also be seen in Yemen, some Pacific islands, and parts of Australia.Rose, D. J. W., Dewhurst, C. ...

Mythimna Unipuncta
''Mythimna unipuncta'', the true armyworm moth, white-speck moth, common armyworm or rice armyworm, is a nocturnal agricultural pest belonging to the family Noctuidae. This moth is also commonly referred to by the scientific name ''Pseudaletia unipuncta''. The species was first described by Adrian Hardy Haworth in 1809. ''Mythimna unipuncta'' is found in the Americas and in parts of Europe, Africa and Asia. Its original distribution is North and South America. It has been introduced to other places from there. They are known as armyworms because the caterpillars move in lines as a massive group, like an army, from field to field, damaging crops.Palmer, Geoff (July 23, 2012)"Pest Alert - Armyworms Round Two Hit Hay and Corn Crops" ''Agriculture and Market''. The true armyworm has a distinct migration pattern in which they travel north in the spring and south in the fall to ensure that mating occurs in a favorable environment in the summer. While progressing through the life cyc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spodoptera Mauritia
''Spodoptera mauritia'', the lawn armyworm or paddy swarming caterpillar, is a moth of the family Noctuidae. The species was first described by Jean Baptiste Boisduval in 1833. Able to eat many types of food, it is a major pest throughout the world. Distribution It is widespread from the Red Sea to India, Myanmar, Sri Lanka, Malaya to Australia and widespread in the Pacific Islands, including the Solomons, New Hebrides, Fiji, Samoa, Hawaii, the Society Islands, Austral Islands, Marquesas and the Marshall Islands. Description The wingspan is about 40 mm. It is dark grey brown with a rusty tinge on its body. The abdomen is fuscous. Forewings with sub-basal, antemedial and postmedial double waved lines indistinct. The orbicular small and ochreous, whereas reniform blackish. Submarginal line whitish and irregularly waved. There is a white patch often can be seen between orbicular and reniform and a dark patch on the central marginal area. Hindwings opalescent and semi- hy ...

Mythimna Separata
''Mythimna separata'', the northern armyworm, oriental armyworm or rice ear-cutting caterpillar, is a moth of the family Noctuidae. It is found in China, Japan, South-east Asia, India, eastern Australia, New Zealand, and some Pacific islands. It is one of the major pests of maize in Asia. The species was first described by Francis Walker in 1865. Etymology They term "armyworm" is used because of their habit to spread out in a line across a lawn or pasture, and slowly "march" forward, consuming the foliage they encounter. Description The wingspan is 35–50 mm. Males lack paired tufts on the basal segment of the abdomen below. The forewings are greyish yellow with a dark-grey or reddish-yellow tinge. The round and reniform spots are light or yellowish with indistinct edges, whereas reniform spot with white point at lower margin. External wing margin blackened obliquely from top backward, with dark stroke and with a row of dark points. Hindwings are grey, with dark extern ...

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Spodoptera
''Spodoptera'' is a genus of moths of the family Noctuidae erected by Achille Guenée in 1852. Many are known as pest insects. The larvae are sometimes called armyworms. The roughly thirty species are distributed across six continents. Description No tufts behind collar as in '' Euplexia'', but only tufts present on metathorax. Scales much smoother. Abdominal tufts slight. Fore tibial tufts are very developed. Cilia slightly crenulated. Antennae almost simple.
