Abstract

The effectiveness of technical products of Naled, Lambada, Fenthion (Lebaycid), Fenitrothion (Sumithion), Malathion and Dimethoate (mixed with methyl eugenol in the ratio of 1:4), in addition to commercial Malathion (57% EC mixed with methyl eugenol in two ratios of 1:2 and 2:3) were evaluated under field conditions as male annihilation technique (lure and kill) of Bactrocera zonata (Saunders) (Diptera: Tiphritidae). Plant fiber blocks saturated with mentioned mixtures were used at four governorates of Egypt (Damietta, Dakahlia, Ismailia and Fayoum) over 12 successive weeks. Efficiency (as lured and killed populations per block per day) of all tested mixtures degraded over time regardless the area. The obtained results revealed that Naled mixture was significantly superior to all other mixtures regard less area or inspection. Naled mixture blocks were relatively effective for up to 8 weeks while others efficiency did not exceed 4 weeks. Commercial Malathion (1:2), technical Malation, Dimethoate were the worth. It was recommended that Naled mixture can be used successfully in B. zonata male annihilation technique and renewed every two months. Lambada, Lebaycid, Sumithion, commercial Malathion (2:3) mixtures could be used with monthly renewal.
