Examplesofsebumsebum Each day target 1 (control) was treated with 200 ml of solvent (dichloromethane) and target 2 (test) with 200 ml ofsebumsolution. From theCambridge English Corpus The acidic fraction ofsebumhad no detectable activity, but both the non-acidic and phenolic fractions did. From theCambridge English Corpus Each day 400 ml ofsebumsolution in methanol were applied to the test net and 400 ml of methanol were applied to the control. From theCambridge English Corpus The treatments were alternated between two sites for nine days (as long as thesebumlasted). From theCambridge English Corpus The presence of flanking nets with or withoutsebumdid not increase the catch of either species significantly. From theCambridge English Corpus Despite this, the responses of tsetse flies to the skin secretions of hosts (hereaftersebum) have not been extensively investigated in the field. From theCambridge English Corpus This paper reports a series of experiments designed to investigate the activity of oxsebumon tsetse in the field. From theCambridge English Corpus The effects ofsebumor its fractions were thus tested as additions to this basic attractant. From theCambridge English Corpus The latter also causes the skin to become dry assebumproduction reduces, therefore increasing the possibility of mechanical stress. From theCambridge English Corpus In the present experiments thesebumextract was crude and the concentrations (in host equivalence per unit time) was not measured. From theCambridge English Corpus Testing of fractions ofsebumrevealed active component(s) in the phenolic and non-acidic fractions but not in the acidic fraction. From theCambridge English Corpus Sebumcollected in dichloromethane, andsebumcollected in methanol were used in two successive experiments. From theCambridge English Corpus Treatments 1 and 3-had 200 ml of solvent applied to the target daily and treatments 2 and 4 had 200 ml ofsebumsolution applied daily. From theCambridge English Corpus The effect ofsebumwas to attract more flies to the target rather than to induce a landing response in a higher proportion of attracted flies. From theCambridge English Corpus As thesebumwas applied to the cloth, the electric grids were moved with treatments and thus any difference in the efficiency of the grids is confounded with treatments.
