담배거세미나방 핵다각체병바이러스의 온도별, 농도별로 병원성 검정결과는 다음과 같다. SINPV의 온도에 따른 담배거세미나방 유충 영기별 LC 은 20-28범위에서는 1,3,5령에서 온도가 높아질수록 낮아졌으나 32에서는 높아졌다. LT 은 핵다각체병바이러스 1.0 Polyhedral inclusion bodies (PIBs)/ml에서 온도조건(20-32)이 2와 24에 비하여 28와 32에서 짧았다. 또한 바이러스 농도가 높고, 유충의 영기가 어릴수록 짧아져 LT 은 온도조건, 바이러스 농도, 유충 영기에 의존하였다.

This experiment was conducted to investigate pathogenicity of Spodoptera litura nucleopolyhedrovirus (SINPV) with different temperatures to mass production. In laboratory, LC values of SINPV were 5.53410 PIBs/ml and 4.l010PIBs/ml in 1st instar larvae at 2 and 28, respectively, but those were increased at 32. LC at 3rd and 5th instar larvae were showed the lowest value at 28. LT values of SINPV in 1.010 PIBs/ml were determined at various temperature conditions (20-32). The result showed that treatments at 28 and 32 shortened LT values, but treatments at 2 and 24 was relatively longer. Also LT values was shortened in high concentration and young larva. LT values are dependent on the temperature, viral concentration and larval instar.
