Enhancement of Mating Performance of Sterile Males of Melon Fly,<i>Zeugodacus cucurbitae</i> (Coquillett) Through Methoprene and Cue Lure

The male pupae of Melon fly, Zeugodacus cucurbitae were irradiated at 30 Gy gamma radiation using Cobalt-60 source. Freshly emerged sterile males (30 Gy) exposed to different regimes methoprene and yeast hydrolysate as protein Sterile 10, 12 14 days old cue lure hydrolysate.
