| Abstract | ||
| This study was conducted to evaluate the efficiency of direct spraying technique for different concentrations of insect growth regulators to cause the death for termite workers in laboratory conditions and the incubator conditions at a temperature of 30 ± 5and the relative humidity of 80 ± 10% in 2011-2012. The study results showed high effectiveness for all tested Insect growth regulators Alsystin (Triflumuron) and Dimilin (Diflubenzuron) in causing mortality to termite workers at various concentrations and for booth study conditions, all concentrations characterized to cause gradual mortality at the beginning of treatment and increased with an increase in exposure time. The rate of mortality reached 100% after 3 weeks at all concentrations of the first exposition under the laboratory and incubator conditions. The effectiveness of Alsystin increased by the increasing of the concentrations , but the increasing of the Dimilin concentrations did not effect in increasing the proportion of mortality during infections, The results of the study showed that the efficiency of the of Alsystin and Dimilin in the causing of mortality less over the time, but their efficiency is more and faster in causing of mortality when the temperature is relatively stable in the incubator conditions compared to fluctuations in temperature at laboratory conditions during successive exposition, Also the duration of the growth regulators effective in causing death lasted 180 - 200 days in laboratory conditions and were220 days in the incubator conditions. | ||
