摘要 使用吖啶橙对卵进行选择性染色，结果表明，野生采集的雌性地中海果蝇（Ceratitis capitata Wiedemann）在先前被卵侵染的果实中每窝产卵量比在未受侵染的果实中少。这种效应显然归因于雌性在产卵后沉积的标记信息素：受卵侵染但不含标记信息素的果实的窝数与未受感染的果实的窝数没有统计学差异。人工转移标记信息素的未受感染的果实的离合器尺寸显着低于未受感染和未经处理的水果。标记信息素对来自实验室中保存了数百代的品系的雌性的窝数具有可比性但不具有统计显着性的影响。
Abstract Using acridine orange to selectively stain eggs, we showed that wild‐collected female Mediterranean fruit flies (Ceratitis capitata Wiedemann) laid fewer eggs per clutch in fruit previously infested with eggs than in uninfested fruit. This effect is apparently attributable to marking pheromone deposited by females after oviposition: clutch size on fruit infested with eggs but free of marking pheromone was not statistically different from that on uninfested fruit. Clutch size on uninfested fruit on which marking pheromone was artificially transferred was significantly lower than that on uninfested and untreated fruit. Marking pheromone had a comparable though not statistically significant effect on the clutch size of females originating from a strain maintained in the laboratory for several hundred generations.
