摘  要：
本文报导用记纹方法测定粘虫蛾飞翔持续时间和振翅频率所获得的结果。 粘虫蛾在羽化展翅后就能飞翔,随后,飞翔能力依蛾龄增长逐渐增加,至羽化后第3、4天达最强,此时室内饲养的成虫,在24小时内平均累积的飞翔时间达10.8小时,野外挖回的蛹羽化的成虫达20.6小时。羽化后5天,由于体内卵发育成熟,飞翔能力又逐渐降低。相同蛾龄的粘虫,飞翔持续时间可能受环境温度和营养条件的影响,环境温度较低时飞翔持续时间较长,饥饿显著地降低飞翔时间。长时间的记录表明,有些粘虫蛾在48小时内能累积飞翔30-40小时,若干个体能连续地飞翔36小时,这是迄今在实验条件下昆虫所能达到的最长飞翔时间。 粘虫蛾的振翅频率,雄虫较雌虫高。两性振翅频率都依蛾龄而变化,从羽化开始至第3天,随蛾龄而增加,3-12天中,雄蛾变化较小,雌蛾在第7天后则显著地降低。振翅频率依温度升降而变化,其关系曲线呈抛物线型。 突然的闪光刺激或声音刺激,可临时增加振翅频率和振幅,亦可使未飞翔的粘虫蛾开始飞翔。

STUDIES ON THE FLIGHT OF THE ARMYWORM MOTH (LEUCANIA SEPARATA WALKER) Ⅰ.FLIGHT DURATION AND WINGBEAT FREQUENCY

摘  要：
Observations on the flight duration and wingbeat frequency were made in thelaboratory at various constant temperatures and 65--75% relative humidity. The mothsused consisted of individuals emerged from pupae collected from the field and rearedin insectary. The results obtained indicated that some individuals of the moths can fly continouslyat 17℃ for 36 hours. Fig. 4 But the duration of flight varied with the insect age. In themoths one day after emergence it was shorter as campared with those of older ones.The longest duration has been shown by those moths aged 3--4 days. Most of thefemale moths 5 days after emergence had fully developed ovaries, and their flight dura-tion dropped down rapidly. This fact suggests that the period before sexual maturationwould be the optimal time for the insects to carry out long distance migration. Nutrition and environmental temperature would influence the flight ability of themoths; the flight duration of the moths under starvation condition decreased apparently;and at lower temperatures it will be prolonged (table 2, 3). The wingbeat frequency varies with the age of moths, as shown in Figure 1. It isworth while to note that the difference in frequency of the two sexes increases with age,and fluctuates slightly with temperature within the range of 25--30℃, beyond which theinfluence of temperature on wingbeat frequency becomes apparent. Light or sound stimulation may affect the flying behaviour of the armyworm moths.Flash light or sound may initiate the flight of the resting moths (Fig. 5A, 6A) or causethe wingbeat frequency of flying moths to increase temporarily (Fig. 5B, 6B), with afactor of 6% for light stimulus and 8% for sound stimulus. They also cause the ampli-tude of wingbeat to increase temperarily (Fig. 7). The latent period of these responsesdre 0.08 and 0.09 second for light and sound stimulation respectively.
