The effect of ox skin secretions (sebum) on the behaviour of tsetse flies, Glossina spp., was investigated in the field using electrified targets, some of which operated intermittently, and by direct observations of flies landing on treated and untreated cloth. As the off-period of an intermittently operating electrified target increased, the catch decreased both with and without the sebum present. Targets with sebum always caught more flies than targets without sebum, but there was no evidence to suggest that sebum increased the duration of stay on a target. Direct observations of flies on cloth targets revealed that for both species the presence of sebum reduced the duration of contact and for G.pallidipes the number of return contacts was increased. The results from direct observations were used to predict the number of repeat landings that would need to be made by flies in order to account for the catch of tsetse at intermittently electrified targets.
在野外，使用带电目标（其中一些间歇性运行）并通过直接观察苍蝇落在经处理和未经处理的布料上的情况，研究了牛皮分泌物（皮脂）对采采蝇（舌蝇属）行为的影响。随着间歇性运行的带电目标的关闭期增加，无论有无皮脂，捕获量都会减少。有皮脂的目标捕获的苍蝇总是比没有皮脂的目标多，但没有证据表明皮脂会增加在目标上停留的时间。对落在布料目标上的苍蝇的直接观察表明，对于这两个物种，皮脂的存在都减少了接触时间，而对于淡足舌蝇，返回接触的次数增加了。直接观察的结果被用来预测苍蝇需要进行的重复着陆次数，以便解释在间歇性带电目标上采采蝇的捕获情况。
