Cross infection of Pieris brassicae granulosis virus on other siblings of Pieris species
Pieris brassicae granulosis virus (PibrGV) has been found to infect yet another two siblings namely P. canidia Linn. & Pontia daplidice (=Pieris daplidice) (Roeber) in addition to P. brassicae (Linn.). The susceptibility of P. canidia and P. daplidice has been established clearly in this work by inoculating them with PibrGV @ 5x104 occlusion bodies (OBs) per ml by the conventional leaf disc method. All the inoculated larvae exhibited typical symptoms of viral infection after 5-7 days of post infection. The above three species of the genus Pieris occur on cabbage and cauliflower plants at different periods in the valley region of Imphal and therefore, it is possible to control all the three species of Pieris using the same virus. LC50 value of PibrGV on P. brassicae, P. canidia and P. daplidice was found to be 7.9x104; 10x106; and 6.3x106 OBs/ml and the LT50 was 134.89; 138.03; 174.50 hours, respectively.
