Popis: | Different concentrations of Neem Azal-T/S were used in an artificial diet, to study the mortality of the greater wax moth Galleria mellonella. A Neem formulation and different ages of natural beeswax combs were used for the effective management of the wax moth. While the diet was being prepared, Neem Azal-T/S was directly added ensure that the Neem formulation was distributed evenly in the diet at concentrations of 0.25, 0.5, 1, 2, and 4%. The obtained results showed that the different concentrations of Neem Azal-T/S mixed in the prepared artificial diet had a significant efficacy against the tested 2nd instar larvae. An outstanding elongation of the 2nd larval instar was clear in comparison with the control, even at the least tested concentration (0.25%). Neem Azal-T/S at 4, 2,1, and 0.5% caused 100% mortality for all tested larvae. When using a 4% concentration, all the tested larvae died in the 2nd instar. However, when using a 2% concentration, the larvae died in the fifth instar. When using a decreased concentration of 1.0 and 0.5%, some of the larvae were tolerant and lived till the 6th instar. Feeding the larvae on beeswax combs treated with 2% Neem Azal-T/S, caused 100% mortality when fed on very old wax. When the diet was old wax treated with 2% Neem Azal-T/S, a 91% mortality was recorded. When the diet was new wax treated with 2% Neem Azal-T/S, a 90% mortality was recorded. A 4% Neem formulation caused mortality for all larvae during the first week of treatment on the different tested ages of beeswax combs. |
