In a laboratory experiment, males of Tetranychus cucurbitacearum Sayed were attracted to crude ether extract of about 2000 quiescent female deutonymphs. Male attraction varied over the range of concentrations tested (100, 10, 1.0, 0.1 and 0.01 deutonymph equivalents (DE) / ml). Tests were conducted on sweet potato leaf discs placed upon moist absorbent cotton wool. Several tested materials (pink cardboard, filter paper, cotton wool, sponge and plant leaf tissue) were used as substrates for the crude extract. Males were examined after o.5, 1, 1.5, 2, 12, 24, 36 and 48 hours from emergence. Male attraction was measured as a percent of responses to treated sites and corrected for occasional visits to untreated check sites. Strongest attraction (35.62 %) occurred at 1.0 DE / ml. Decreased attraction occurred, however, at the higher and lower concentrations.
