Report of the 1979 International Collaborative Project on brown planthopper resistance. A collaborative project was initiated in South and South-east Asia in 1979 with 3 aims: geographically to characterise biotypes of Nilaparvata lugens (Stal), on the basis of the reaction of different rice varieties and thereafter to identify sourc...

Sixty-seven entries of the 9th IRWBPHN, including 2 of susceptible control TN1 and local resistant control ARC6248, were screened for resistance to Sogatella furcifera under glasshouse conditions. The standard evaluation system for rice was used f...

A severe outbreak of Sogatella furcifera occurred in the Annamalainagar district of Tamil Nadu, India, in December 1986. It affected about 50 ha of transplanted IR20 and IR50, the latter being more seriously affected. About 250-300 nymphs and adul...
