Abstract

The ovipositional response of Lucilia cuprina flies to odours emanating from fleece-rot lesions of greasy wool in which Pseudomonas aeruginosa bacteria proliferated, was studied. Fractionation of the fleece-rot odours was carried out by bubbling the volatile components through hydrochloric acid and sodium hydroxide solutions to remove basic odours and acidic odours respectively. It was found that the acidic/neutral odours of fleece-rot wool, when perfused into wet, greasy wool stimulated L. cuprina to oviposit. On the other hand, the basic/neutral odours of fleece-rot wool were virtually unattractive to the gravid fly. Similarly, the acidic/neutral odours emanating from fleece-rot lesions of clean wool from which the non-fibre components, wax, suint and epithelial debris, had been removed by scouring, were found to be unattractive to the gravid fly in choice tests.

摘要

研究了铜绿蝇对感染了羊毛腐烂病的油腻羊毛所散发气味的产卵反应，在这种腐烂的羊毛中，铜绿假单胞菌大量繁殖。通过将挥发性成分分别通入盐酸和氢氧化钠溶液中以去除碱性气味和酸性气味，对羊毛腐烂气味进行了分馏。结果发现，当将羊毛腐烂病的酸性/中性气味灌注到潮湿、油腻的羊毛中时，会刺激铜绿蝇产卵。另一方面，羊毛腐烂病的碱性/中性气味对怀孕的铜绿蝇几乎没有吸引力。同样，在选择试验中发现，经过擦洗去除了非纤维成分（蜡、羊汗和上皮碎片）的清洁羊毛上的羊毛腐烂病损伤所散发的酸性/中性气味，对怀孕的铜绿蝇没有吸引力。
