摘 要: | 白背稻虱自然种群扑灯日照阈限为0.91x,其典型的扑灯活动是一个扑灯量呈型的节律性过程。这种扑灯节律是其种群离株起飞节律的一个局部反映。 33米和1.3米两个高度的对照灯诱试验表明,前者灯下稻飞虱诱集量通常大大高于后者灯下诱量。表明稻飞虱种群存在趋光延迟现象,即夜间离株后首先表现强烈的升空飞行习性,在经历一定时间和距离的飞行活动后趋光表现迅速增强。

Behavioral Mechanism of Phototactic Response of Natural Planthopper Population (Sogatella furcifera and Nilaparvata lugens) |

Abstract: | The upper daylight illuminance threshold for white backed planthopper population to respond to a trap light was 0. 9 1x. The typical phototactic response of the planthopper in the night without rain and wind was a rhythmatic process with a "(?) "shaped catching curve. The phototactic rhythm would be a partial reflection of the taking-off rhythm of the planthopper.
The smbers of the two kinds of planthoppers caught by the high-altitude light (31 meters above the ground) were usually far much greater than that by the light near the ground (1. 3m high). There existed a time lag of phototaxi on the planthoppers, macropterous populations, while taking off from the rice plant, macropterous adults of the planthoppers perform high-flying habit more intensely than responding to a trap light, and after they had flown for some time and distance their phototaxis increased rapidly. |
