Abstract

The toxic & repellent effects of some different silicon sources in powder and liquid forms were assayed on peach fruit fly Bactrocera zonata for 3 days under laboratory conditions. In a toxicity study against adult and pupa stages, the results indicated that a potent effect of diatom, kaolin, aglive Si 300 and bentonite in powder form of silicon with corrected mortality from 40 to 100 %, respectively. In a liquid form, potassium silicate formulations had toxic effect in different corrected mortality percentage from 55.7 to 100%. Potassium salt, (boiled lime & sulfur) and palmito formulation gave highly toxic effects as a traditional treatment. In a repellency percentage, the results indicated that palmito, kaolin, bentonite, boiled lime & sulfur and kaolinated potassium silicate showed the highest repellent action as compared with other treatments. With different concentrations, boiled lime & sulfur treatment gave the most repellency percentage against adult of peach fruit fly with 80 to 33% after 1-6hrs. from treatment, these concentrations the percentage of repellency from 53.0 –100.0% after 24hrs. from treatment. Kaolinated potassium silicate showed the second order in repellent action against adults which gave PR% ranged from 35 to 65% and 55 to 95% repellency after 1-6 & 24hrs., respectively at different concentrations.  Si El-Ghanem treatment showed the least effect with PR% from 30 to 10% after 1-6hrs. and 40 to 15% after 24hrs. The silicon studied could provide suitable alternatives into IPM programs.
