Begin scouting for seed midges 5 to 7 days after seeding the field. Look for hollow seeds and chewing marks on the seed, roots, or seedlings. If you confirm rice seed midge in a field.

In a review of the taxonomy of the rice gall-midge long known as Pachydiplosis oryzae (Wood-Mason), the authors draw attention to a catalogue by M.D. Delfinado & D.E. Hardy published in [RAE/A 62, 90] in which the species is transferred to the genus Orseolia, since Pachydiplosis has been of the information in this paper on the ecology and control of this important Cited by: 8.
Orseolia oryzae, also called the Asian rice gall midge, is a species of small fly in the family 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".Family: Cecidomyiidae.

Tolerance to gall midge has also received much genetic study. Seven major genes responsible for gall midge resistance (Gm1, Gm2, gm3, Gm4, Gm5, Gm6(t), and Gm7(t)) have been tagged.

Inheritance of resistance to gall midge in five resistant rice cultivars was studied under conditions of natural infestation. All five cultivars were found to have a single dominant gene for resistance.
Allele tests revealed that Usha, Samridhi, and Bd have the same gene for resistance; this gene was designated Gm Surekha and IET have the same gene for resistance, which is Cited by: Recent studies have shown that ant behaviour following the initial identification of food location by scout ants may be even more complicated than it seems.

The gall midge induces cylindrical-shaped galls, proportionately more of which were located on primary lateral veins or midveins of the lower surface of host leaf, as compared with on the upper surface.
The main characteristic of well-developed galls and adults were observed and described, as well as the occurrence and harm of gall midge. INTRODUCTION. Rice (Oryza sativa) is the most widely consumed food crop and was grown on over million ha worldwide inwith over 18% grown in China ().As one of the centers of origin, China has been cultivating rice for over 7, years ().Rice is a staple food for over 1 billion people in China in addition to 2 billion people in other countries ().
Rice is a staple food in West Africa, where its demand keeps increasing due to population growth. Hence, there is an urgent need to identify high yielding rice cultivars that fulfill this demand locally. Rice hybrids are already known to significantly increase productivity. This study evaluated the potential of Asian hybrids with good adaptability to irrigated and rainfed lowland rice areas in Cited by: 3.
