Larva

Description

The wingspan of the male is 18–22 mm and the female is 34 mm. [2] Adult males are smaller than the females. Males are brownish ochreous. Forewings irrorated (sprinkled) with dark scales and with the veins slightly streaked with fuscous. A black spot found at lower angle of cell. There is an oblique fuscous line runs from apex to vein 2. A marginal black specks series can be seen. Hindwings ochreous white. Female fuscous brown with pale fuscous hindwings. [3]

Ecology

The larvae feed on Oryza sativa . It is considered as a major rice pest throughout India, Sri Lanka as well as in various parts of Nepal, and it devastates harvests annually. They bore the stem of their host plant. Full-grown larvae are pale yellow to yellowish green with a brown head and reach a length of 20 mm. Pupation takes place in a white silk cocoon.

Damage

After hatching, early instars bore into the leaf sheath and causing longitudinal yellowish-white patches as a result of feeding. Then it invades the stem of the rice plant and stays in the pith to feed on the inner surface of the stem wall. These are not externally visual as symptoms. Severe feeding causes a deep circular cut through the parenchyma tissue showing deadhearts at the vegetative stages and whiteheads at the reproductive stages. [4]

Control

Due to heavy damage to rice throughout the world, many controlling measures are underway. Chemical, physical, and biological controls and many traditional methods are used to control the pest at any stage of its life cycle. Numerous pest resistant paddy varieties have been genetically modified and introduced in to the fields by the local governments. In biological control, egg parasitism is high and widespread. Species of the three genera Telenomus , Tetrastichus and Trichogramma are greatly effective against eggs, larva and adult moths. [4]

Conocephalus longipennis, a bush cricket is known to consume moth eggs. Other than insect parasitoids, fungi, bacteria, viruses and mermithid nematodes are also used for Integrated Pest Management (IPM).

It is found in Lesotho, KwaZulu-Natal, Transvaal, Zimbabwe, Mozambique, Zambia, Malawi, Congo, Kenya, Uganda and on Madagascar. It is also present in India, China, Korea, Indonesia (Sumatra), Japan, Sri Lanka, Taiwan, Vietnam and the Himalayan region.

<i>Chilo suppressalis</i> Species of moth

<i>Leucinodes orbonalis</i> Species of moth

Leucinodes orbonalis, the eggplant fruit and shoot borer or brinjal fruit and shoot borer, is a moth species in the genus Leucinodes described by Achille Guenée in 1854. Its native distribution is in the tropical and subtropical parts of Australia and Asia, where it is recorded from Pakistan, Nepal, India, including the Andaman Islands, Sri Lanka, Bangladesh, Myanmar, Laos, Cambodia, Vietnam, Thailand, China, Taiwan, Japan, Malaysia, Singapore, Brunei, the Philippines, and Indonesia (Java). It has also been intercepted from fruit imports in the U.S.A., the Netherlands, Denmark and Great Britain, where it was also reported from the wild. A taxonomic revision of the Leucinodes species of Sub-Saharan Africa concluded that L. orbonalis is currently not present in Africa, and that previous records of this species were misidentifications of previously undescribed species.

<i>Maliarpha separatella</i> Species of moth

Maliarpha separatella, the African white stemborer, is a species of moth of the family Pyralidae. A worldwide paddy pest, it is found throughout African countries of Cameroon, Mali, Réunion, Madagascar, South Africa, and many Asian paddy cultivating countries such as Myanmar, India, and Sri Lanka. Though they are reported from China and Papua New Guinea, they are also known to attack sugarcane.

<i>Eldana</i> Genus of moths

Eldana is a genus of moths of the family Pyralidae containing only one species, the African sugar-cane borer, which is commonly found in Equatorial Guinea, Ghana, Mozambique, Sierra Leone and South Africa. Adults have pale brown forewings with two small spots in the centre and light brown hindwings, and they have a wingspan of 35mm. This species is particularly relevant to humans because the larvae are a pest of the Saccharum species as well as several grain crops such as sorghum and maize. Other recorded host plants are cassava, rice and Cyperus species. When attacking these crops, E. saccharina bores into the stems of their host plant, causing severe damage to the crop. This behavior is the origin of the E. saccharrina's common name, the African sugar-cane borer. The African sugar-cane borer is a resilient pest, as it can survive crop burnings. Other methods such as intercropping and parasitic wasps have been employed to prevent further damage to crops.

<i>Sesamia inferens</i> Species of moth

Sesamia inferens, the Asiatic pink stem borer, gramineous stem borer, pink borer, pink rice borer, pink rice stem borer, pink stem borer, purple borer, purple stem borer or purplish stem borer, is a moth of the family Noctuidae. The species was first described by Francis Walker in 1856. It is found from Pakistan, India, Sri Lanka, Myanmar to Japan and the Solomon Islands. A polyphagous species, it is a major pest in many crops worldwide.

Ancylolomia chrysographellus, the angled grass moth, is a species of moth in the family Crambidae. It is found on Cyprus and in Kenya, Uganda, Yemen, India, Pakistan, Sri Lanka, Myanmar, China, Korea, Japan, Taiwan, the Philippines and Indonesia.

Parapoynx stagnalis, the rice case bearer or rice caseworm, is a species of moth in the family Crambidae. It has a wide distribution and is found in India, Sri Lanka, South-East Asia, South Africa, South America, southern Europe, Russia and Australia.

<i>Ostrinia furnacalis</i> Species of moth

Ostrinia furnacalis is a species of moth in the family Crambidae, the grass moths. 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. The Asian corn borer is part of the species complex, Ostrinia, in which members are difficult to distinguish based on appearance. Other Ostrinia such as O. orientalis, O. scapulalis, O. zealis, and O. zaguliaevi can occur with O. furnacalis, and the taxa can be hard to tell apart.

Some sources have affixed the common name "sugarcane top borer" to it, despite it not being found in sugarcane, because they are confused with the species Scirpophaga excerptalis, which is an actual borer in the tops of sugarcane. Another newer common name that has been invented for these moths is "white rice borer".

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.

Sturmiopsis inferens is a species of fly in the family Tachinidae. It is native to Asia and is a parasitoid of various moth species whose larvae feed inside the stems of sugarcane, rice and other large grasses, including the Gurdaspur borer and the sugarcane shoot borer.

Trichogramma japonicum is a minute wasp parasitoid from the Trichogrammatidae family in the order Hymenoptera. T. japonicum parasitizes the eggs of many pest species, especially Lepidoptera found in many monocultures. They are entomophagous parasitoids that deposit their eggs inside the host species' egg, consuming the host egg material and emerging from the egg once development is complete. T. japonicum can be found naturally in rice ecosystems, but are dispersed commercially to many monocultures as a biological control. The mitochondrial genomes of T. japonicum are significantly rearranged when comparing it to related insects.
