Abstract

In green house studies, rice brown planthopper, Nilaparvata lugens (Stal) and green leaf hopper, Nephotettix virescens (Dist.) have been exposed to Neem gold 4 and monocrotophos at LC70 to LC80 concentrations once in each generation for 26 generations separately. The resultant strains of BPH and GLH have been tested for their resistance development and cross-resistance pattern at the end of 26 generations.
