摘要:

目的 了解家蝇和大头金蝇的产卵基质选择行为。方法 在实验室的养虫笼内观察家蝇和大头金蝇的产卵基质选择行为;在“Y”形嗅觉仪中观察家蝇成虫的气味选择行为。结果 对3种基质进行产卵选择时,家蝇在麦麸、瘦肉和鱼粉中的产卵量分别为86.58%、6.08%和7.34%,前者与后两者的差异有统计学意义(F=162.97;υ=2,15;P<0.01)。而大头金蝇仅在瘦肉上产卵;在双向气味选择的嗅觉仪实验中,当以麦麸为对照时,大多数家蝇和大头金蝇雌雄蝇都选择向瘦肉定位飞行。并且大头金蝇雌雄性对瘦肉的选择率分别为85.02%和72.81%,两性之间的差异有统计学意义(F=8.66;υ= 1,18;P<0.01),而家蝇两性之间的差异无统计学意义;当对新鲜的基质和幼虫取食过的基质进行产卵选择时,家蝇在幼虫取食过的麦麸和瘦肉上的产卵量分别为73.43%和57.57%,大头金蝇在幼虫取食过的鱼粉和瘦肉上的产卵量分别为100% 和72.88%,并且它们与新鲜基质上的产卵量差异都具有统计学意义。结论 产卵基质的气味与同种幼虫遗留的信息物质对家蝇和大头金蝇的产卵选择行为有显著的影响,这对于蝇类引诱剂的开发和提高蝇类产卵量具有一定的指导意义。

Abstract:

Objective To identify the choice of spawning substrates by Musca domestica and Chrysomya megacephala. Methods The choice of spawning substrates by M. domestica and C. megacephala in insect rearing cages was recorded in laboratory. The odor preference of adult M. domestica was measured using a Y-tube olfactometer. Results A total of 86.58%, 6.08% and 7.34% of M. domestica laid eggs on the three kinds of substrate, wheat bran, lean meat and fish meal, respectively. The difference between the first spawning substrate and the others was significant (F=162.97;υ=2,15;P<0.01). In contrast, C. megacephala laid eggs only on lean meat. In the two-way choice test for odors using an olfactometer, most of the males and females of M. domestica and C. megacephala were orientated towards lean meat, with wheat bran as the control. 85.02% of the males and 72.81% of the females of C. megacephala chose lean meat, between which the difference was significant (F=8.66; υ =1,18;P<0.01); however, the gender difference was insignificant in M. domestica. As for the comparison between fresh substrates and substrates fed by larvae, 73.43% of M. domestica laid eggs on the fed wheat bran and 57.57% on the fed lean meat, while 100% of C. megacephala laid eggs on the fed fish meal and 72.88% on the fed lean meat. Each of the egg laying amount was statistically different from that on fresh substrates. Conclusion Odors of the spawning substrate and information substances left by the larvae of the same species have a significant impact on the choice of spawning substrates by M. domestica and C. megacephala, which is of guiding significance for the development of fly attractants and the improvement of the fecundity of flies.
