Relative Attractiveness

Grapefruits and sweet oranges were equally attractive to, and elicited comparable oviposition behavior from, naïve laboratory-strain female Mexican fruit flies, Anastrepha ludens (Loew), in wind-tunnel experiments. Neither fruit attracted nor elicited oviposition behavior from naïve wild females. For laboratory females, experience with either grapefruits or oranges enhanced attraction to both fruits and enhanced attraction to the experienced fruit more so than to the other, but did not affect oviposition propensity. For wild females, experience with either fruit enhanced attraction to both fruits, enhanced attraction to the experienced fruit more so than to the other, and increased oviposition propensity on both fruits. Also, wild females experienced with grapefruits oviposited more readily in grapefruits than did those experienced with oranges. Both laboratory and wild females experienced with either fruit directed less oviposition behavior toward wind-tunnel walls than did naïve females. Laboratory males were attracted to both fruits, but wild males were attracted to neither. Overall, experience with fruit had smaller effects on responses of males compared with effects on females.

1. Apparatus has been devised to record the principal parameters of the flight performance of tethered fruit-flies in a wind tunnel. 2. Typically these flies achieve level flight (lift = weight) at 200 cm./sec. and a body angle of + 10°. Lift varies directly with body angle except at very high angles; the stroke parameters are invariant with body angle. 3. Evidence is presented suggesting that these measurements are applicable to free flight. 4. The adaptive significance of the absence of a ‘lift-control reaction’ in fruit-flies is discussed.

Tethered Flight

1. In tethered flight in a wind tunnel fruit-flies adjust lift and thrust by shifting the horizontal component of the lower extreme wing position. The upper extreme wing position is nearly constant. 2. Stroke angle and stroke plane are fully interdependent parameters. 3. Angle of attack varies along the length of the wing; no length-wise twisting occurs. 4. Angle of attack varies with flying speed; pitch is unchanged as speed is increased. 5. These characteristics suggest that the flight machinery of fruit-flies is considerably simpler than that of larger flying animals.
