Abstract:

Ecological approaches such as the use of resistant varieties are major components of pest management in rice. Rice cultivars resistant to whitebacked planthopper (WBPH) Sogatella furcifera (Horvath) (Hemiptera: Delphacidae) are important in integrated pest management. A study was carried out to elucidate the interactions between rice genotypes resistant to WBPH and its egg parasitoid Anagrus nr. flaveolus (Hymenoptera: Mymaridae). Ten rice genotypes-PSBRc 10, Babawee, IR36, IR72 (resistant), A5174, A5368, A5301, A5372 (moderately resistant), IR26 (susceptible), and TN1 (highly susceptible)-were used in the screenhouse and microplot experiments.
