| Abstract | ||||
| The present study was carried out to evaluate the toxicity of Syotin 25% (Pyrethroid) Solar (petroleum product) or diesel fuel and plant ash to Bactrocera. zonata (Saunders), full grown larvae in three different soil types sandy, clay and mixed soil (mixture of sandy and clay (1:1) by volume), and the effect of different soil depths and types on the emergence rate of B. zonata pupae. The results proved that, Solar in sandy soil recorded the highest mean of mortality 71.044% followed by Syotin in clay soil recording 68.89% and there is no significant differences in means of mortality for Syotin and Solar in all soil types while there is a significance in means of mortality for ash treatments. Syotin recorded the lowest LC50 value 0.925 ml/L while Solar recorded the lowest LC90 value 8.541 ml/l., comparing the efficacy of the three compounds on the mean percentage of mortality regardless to the soil type. Syotin cause the highest mean of mortality 60.9% followed by Solar recorded 55.2%. There is no effect of the type of soil used on the mean percentage of mortality. The highest rate of emerged flies was obtained at the lowest soil depth. At 16 cm depth no emergence was observed in dry clay soil while 3.33% emergence was observed in dry mixed soil at 14 and 16 cm depth. The results cleared that soil's type and depth of burying pupae has an influence of the rate of emergence of B. zonata adults. | ||||
