Abstract

Scirpophagaincertulaspassed through one generation each during rainy season at Agricultural Engineering College, Kumulur. TrichogrammaJaponicum,Trichogrammabraziliensis, Telenomusbeneficiens, Tetra stichus SP. are egg parasites and BraconChinensis, Stenobraconnicenilles, Tropobracon sp. Platygaster. In addition to the above TrichogrammaJaponicum and playgasterOryzac unidentified as key mortality factors of scirpopherga incertulas. Using the key mortality factors the killing power of k value is decrease by second generation.
