Vibration-mediated territoriality in the warty birch caterpillar Drepana bilineataPhysiological Entomology (2008) 33, 238–250

取食有瘤樺木的鉤蛾幼蟲 Drepana bilineata會產生兩種不同的震動訊號(上顎敲擊或摩擦肛上板) 作為同種之間的溝通。以標準的高速攝影搭配雷射都卜勒振動位移計描繪震動訊號的特性，並以行為學實驗測試”該行為是用來宣告占有樺木葉片” 的假說。敲擊行為涉及抬起頭部並打開的上顎的銳利邊緣敲打葉片，當葉片上的居住者偶然遇到同種的入侵者時，就會引起敲擊行為，當入侵者愈靠近時、敲擊的頻率就會愈高。衝突通常在幾分鐘之內就會解決，在試驗中、原居住者獲勝的比例是61%，闖入者獲勝的比例則只有6%。超過三十分鐘的衝突視為平手，試驗中的結果33%會如此。實驗的結果支持震動訊號的功能是為了宣告佔據葉片。震動溝通行為被認為是鉤蛾總科常見的特徵，但是目前只有在 D. bilineata (本研究) and Drepana arcuata兩個種有被描述過。領域行為和發出訊號的在這些物種之間的分化被認為和他們對以絲、葉製作墊子與遮蔽所的相對投資有關。本文亦討論幼蟲之震動溝通的演化趨勢。
Abstract .
The warty birch caterpillar Drepana bilineata produces two distinct types of vibrational signals (mandible drumming and anal scraping) during interactions with conspecifics. Vibrational signalling is characterized using standard and highspeed videography synchronized with laser-doppler vibrometry, and behavioural experiments test the hypothesis that signalling functions to advertise occupancy of birch ( Betula ) leaves. Drumming involves raising the head and striking the leaf with the sharp edges of the open mandibles. Anal scraping involves dragging a pair of specialized oar-shaped setae against the leaf surface. Staged encounters between leaf residents and conspecific intruders result in the resident signalling, with rates increasing as the intruder moves closer. Intruders signal significantly less often than residents. Conflicts are typically resolved within a few minutes, with the resident winning in 61% of the trials, and the intruder winning in 6%. Contests that last more than 30 min are deemed ‘ties’ and comprise the remaining 33% of trials. The results support the hypothesis that vibrational signals function to advertise leaf occupancy. Vibrational communication is believed to be widespread in Drepanoidea caterpillars, but has only been described in two species to date: D. bilineata (present study) and Drepana arcuata . It is proposed that differences in territorial behaviour and signalling between these species are related to their relative investments in silk leaf mats and shelters. The proximate and ultimate bases for the evolution of vibrational communication in caterpillars are discussed.
