Abstract:
A lab experiment was carried out to evaluate the effect of bio products on percent mortality of third and sixth instar Galleria mellonella larvae by the testing of different concentration viz. Pongamia oil and Citronella oil (at 0.3, 0.4 and 0.5% concentration), NSKE, Garlic clove extract and Tobacco leaf extract (at 3, 4 and 5% concentration) and Bacillus thuringiensis (Biobit and Biolep; at 5, 7 and 9% concentration) each tested at 1, 3, 5 and 7 days after treatment for the assess the effect of different concentrations of bio products on greater waxmoth. The experiment conducted on percent mortality or the lethality of all bio products was depends on concentration of the pesticides, higher concentration doses caused higher mortality percent in both third and sixth instar larval stage of greater wax moths. For the higher mortality percent was recorded at 7 days after treatment application on both third and sixth instar larval stage of greater wax moths. The entire management study shows Bt, Biobit (32,000 IU mg^-I) @ 9 gm concentration, Citronella oil @ 0.5% concentration and Pongamia oil @ 0.5% concentration can be recommended for the management of G. mellonella larva in bee hives.
