| Abstract | ||||
| This study evaluated the eco-toxicological parameters of two chlorophyll derivatives, copper chlorophyllin (Cu-chlorophyllin) and magnesium chlorophyllin (Mg-chlorophyllin) on viability of honey bee. Chlorophyll and its derivatives have a wide range of applications such as coloring in food additives and photopesticide against medical and agricultural pests. The results of Cu-chlorophyllin and Mg-chlorophyllin using different concentrations in honey bee's feeding bait indicated their efficiency on honey bee's viability as a function was 10% within the range 10-6 -7x10-6 M/L and reached 25% at 10-5 M/L compared to 5% mortality in control samples. The LC50 of both derivatives showed the Mg-chlorophyllin was less toxic than Cu-chlorophyllin on bee's viability. The maximum mortality was 14% & 21% for Mg-chlorophyllin and Cu-chlorophyllin respectively. Semi-field experiment revealed that the natural activity of honey bee workers outside the hive reduced the effect of chlorophyll derivatives on honey viability of laboratory testing obtained data. | ||||
