| Abstract: | The LD_(50)of two preparations of EONPV(EONPV 2H_2 and EONPV 2H_4)on tea looper larvae were 2.5×10~4 PIB/mL and 2×10~4 PIB/mL respective-ly.By using the 1×10~7 PIB/mL EONPV 2H_2 and EONPV 2H_4 preparations,the LT_(50)of the 3rd instar tea looper larvae were 5.5 and 5.7 days respec-tively.Both preparations of EONPV possessed the UV-proof ability andpotent infectivity to the host.The corrected mortality in the experimentcarried out in lab were more than 96%.The efficacy of control on the 1st,2nd and 5th generations(the area with 5 generations per year)and the6th generation are more than 90% when 20 billion EONPV PIB/mL wasapplied in the field condition.The EONPV was proved to be safe for usein tea garden.Neither EONPV polyhedral bodies nor EONPV particlescould be found in the tissue cell of natural enemies of tea pests,for inst-ance Leis axyridis Pal.,under the electron microscope.No direct infectionoccurred to parasitic hymenoptera(Apanteles sp.). |
