THE EFFECT OF WOOD TYPE , TIME AFTER EXPOSURE AND CONCENTRATION ON TERMIT RESPONSE Microcerotermes diversus Silv. FOR SOME ANTIBIOTICS
Abstract
The results of the study showed the effect of Leucaena leucocephala, Platanus orientalis and Populus alba woods, Concentrations were 0.0025, 0.005, and 0.01% in the Microcerotermes diversus Silv. workers response for Antibiotic Amoxicillin and Nidazole, by spraying and dipping methods, in medium-contrast ratios of insect mortality on the three kind of wood, as it reached: 63.10%, 48.75% and 50.10% respectively by spray, which gave an average rate of mortality after six days 99.38%. While the results showed an increase in the average mortality rates of Termites with an increase in concentration (0.0025, 0.005 and 0.01%), reaching 42.73, 54.60 and 64.70%, respectively, while Nidazole had a clear superiority in the average percentage of deaths of Microcerotermes diversus Silv. , as it reached 61.17%, while it reached 46.86% for amoxicillin. As for the results of the dipping method, there was no significant difference in wood type in the average mortality rates, as it reached 53.62, 56.86 and 51.49%, respectively, while the highest average mortality rate after four days of exposure was 88.23%. Concentrations reached 41.50, 54.73 and 65.75%, respectively, Amoxicillin and Nidazole did not have a significant difference in the mean Termites mortality as it reached 53.92 and 54.06%.
