The effects of hormones on wing dimorphism of Sogatella furcifera were explored by treating the surfaces of 3rd or 4th instar larvae with ZR-515，precocene and RH-2485. The results showed ZR-515 could induce brachypter, the brachypterous adult rates were 45.6%, 50% and 50.26% respectively when the 3rd instar larvae were treated by 10ng/μl ZR-515 and the 4th instar larvae were treated by 1μg/μl or 100ng/μl ZR-515. Precocene could induce macropter, the more macropterous adult were found the higher titer of preconece was applied to the larvae, and the macropter inducement was more effective at the 3rd instar than at the 4th instar, the macropterous adults rates were 100% or 86.67% respectively when S. furcifera were treated by 10μg/μl or 100ng/μl preconece at the 3rd instar. RH-2485 had no effects on wing dimorphism of this insect.
