Abstract : A field experiment was carried out in Khartoum and Gezira States during the period 2010 – 2012, to evaluate the
effectiveness and longevity of plywood, white wood block and sponge wick in comparison with the
recommended method (cotton wick). Oblong plywood blocks applied with the mixture of methyl eugenol (ME)
and malathion (MA) showed more effectiveness and longevity than the white wood blocks, sponge and cotton
wicks. They remained effective in the field for more than four months (135 days). In addition to its effectiveness
and longevity, use of the oblong plywood blocks with (ME+MA) was easy and cheap, in comparison to the
recommended method (cotton wicks). In conclusion, the application of plywood blocks with (ME+MA) is
suitable to be applied in male annihilation technique (MAT) against B. invadens in Sudan. Also, the application
of plywood blocks decreases the cost of ME+MA up to half in comparison with recommended method.
Moreover, this application could be used for controlling B. invadens in and/or out of fruiting season.
