The African rice gall midge, Orseolia oryzivora sp. n., is described and illustrated from adults of both sexes, larvae and pupae collected in West Africa. This species had previously been misidentified as O. oryzae (Wood-Mason), which is a major pest of rice in Asia, but the two species are morphologically distinct in the larval, pupal and adult stages.

The Asian rice gall midge (Orseolia oryzae) is a major pest responsible for immense loss in rice productivity. Currently, very little knowledge exists with regard to this insect at the molecular level. The present study was initiated with the aim of developing molecular resources as well as identifying alterations at the transcriptome level in the gall midge maggots that are in a compatible. Previously, there has been a failure of many studies to identify biotypes of the cecidomyiid Orseolia oryzae, which is a major pest of rice cultivars in many Asian countries. Although high-yielding modern cultivars possessing resistance/tolerance to one or more of the major rice pests are available to farmers, little information is available on the ability of pest populations of O. oryzae to.

Introduction. The Asian rice gall midge, Orseolia oryzae (Diptera: Cecidomyiidae) is an important pest of rice that is responsible for an average yield loss of US $ 80 million annually in India alone [].Cultural, biological and chemical control methods have been employed to alleviate this loss. The most effective method of controlling the pest has been the development of resistant rice. DOI: /ijeab/ Keyword: Gall midge, Chiplima, rice entries, screening, field.

Orseolia oryzae, also called the Asian rice gall midge, is a species of small fly in the family Cecidomyiidae. It is a major insect pest of rice. The damage to the crop is done by the larvae which form galls commonly known as "silver shoots" or "onion shoots".

Abstract The Asian rice gall midge [Orseolia oryzae (Wood-Mason)] is an important rice pest causing an annual average yield loss of about US $80 million in India. The Asian rice gall midge and rice share orseolia oryzae an intimate relationship that there is a constant battle for survival by either partner.

Diverse responses by the rice host against the midge include necrotic hypersensitive resistance reaction, non-hypersensitive resistance reaction and gall-forming compatible interaction. Infestations of susceptible rice varieties by the Asian rice gall midge (Orseolia oryzae Wood-Mason) cause an average annual yield loss of about US$80 million in India and US$ million in Asia (Bentur et al.

The rice gall midge (RGM), Orseolia oryzae (Wood-Mason), is one of the most destructive insect pests of rice, and it causes significant yield losses annually in Asian countries. The development of resistant rice varieties is considered as the most effective and economical approach for maintaining yield stability by controlling RGM.

During the s and early s, screening for resistance and the development of IR8-type rices with multiple disease and insect resistance (including resistance to the rice gall midge) continued, resulting in the production of the modern varieties IR20, IR36, IR42, IR64 and IR   The rice gall midge (RGM), Orseolia oryzae (Wood-Mason), is one of the most destructive insect pests of rice, and it causes significant yield losses annually in Asian countries.

Orseolia oryzae, the rice gall midge, is a major pest of rice in many areas of tropical Asia and is becoming an important pest in Africa. A chronological review of the progress made in various national programmes on varietal resistance, sources of resistance and breeding for resistance is given.

Many resistant varieties have been identified and have been utilized in breeding programmes to. rice varieties resistant to rice gall midge. Inducedresistanceagainstrice gallmidgewas attemptedby applyingsilica fertilizers (Hidaka ) or chelated boron and zinc to rice plants (Panda ).

Gall midge incidencedecreased by 50%by thodhas yet. The Asian rice gall midge, Orseolia oryzae seriously infests the rice of several Asian countries (Bentur et al., ). This major pest causes 10– % crop losses in India (Siddiq, ).

Based on the studies from eastern and southern India, Krishnaiah () reported that the Asian rice gall midge infestation causes an annual yield loss of.

The Oriental species of Orseolia on grasses and rice are revised and keyed; 21 valid species from South-East Asia are treated, one of them newly described. Two taxonomic changes are proposed.

Flies anatomically similar to the rice pest O. oryzae occur on many different grasses, but are treated here under nominal species or as 'Orseolia sp. near O. oryzae'. Fourteen differential rice cultivare under four major donor groups were evaluated at 11 field locations in seven Indian states during 13 years against the rice gall midge, Orseolia oryzae (Wood.

Five biotypes of rice gall midge (GM; Orseolia oryzae) have been identified in India, with the Manipur population being biotype 3 (the Ranchi biotype). However, since a new pattern of reaction has been observed among differential rice varieties.

A standard set of 10 differentials in 4 groups was evaluated in the wet seasons of against the GM population of Iroisemba, Manipur. The gall midge, Orseolia oryzae, is a major dipteran pest of rice affecting most rice growing regions in Asia, Southeast Asia and al and other cultural methods for control of this pest are neither very effective nor environmentally safe.

The gall midge problem is further compounded by the fact that there are many biotypes of this insect and new biotypes are continuously evolving.

The Asian rice gall midge (RGM) Orseolia oryzae (Wood Mason) (Diptera: Cecidomyiidae) is a major pest of rice, leading to yield losses in Thailand and many Asian countries.

Despite an increasing number of reported midge outbreaks and the presence of many susceptible rice varieties, only a few studies have focused on the genetic variation of the midges. Asian rice gall midge (Orseolia oryzae) is one of the major pests of rice which is causing significant economic loss to the crop.

So far 11 gall midge resistance genes have been characterized from different rice varieties and seven biotypes of the pest have been identified based on their reaction to these genes.

Cultivation of varieties containing single resistance gene has resulted in frequent. Rice Gall Midge (Orseolia oryzae Wood-Mason) Submitted by Awaneesh on Tue, 16/02/ - Posted in. English; Management; The larvae of midge are the damaging stage that feed on the growing points producing characteristic gall in the plant transforming regular tillers into tubular galls which dry off without bearing panicles.
