Responses of female hide beetles in Y-olfactometer choice experiments to male gland extract, synthetic (Z9)-unsaturated fatty acid isopropyl esters, benzyl butyrate plus (Z9)-unsaturated fatty acid isopropyl esters and different cadaver odours (bloated, post-bloated, synthetic copy of post-bloated, advanced decay, dry remains) either plus (Z9)-unsaturated fatty acid isopropyl esters or plus male gland extract (one-sided binomial probability tests) versus pure solvent control. Those test solutions which elicited significant results (P <0.001) or strong tendencies (P = 0.058) are highlighted in greyish colour. Numbers inside of the bars denote identified ratios of the particular test preferences. Distinct letters label different test series. Bloated stage: day 3 post-mortem; Post-bloating stage: day 10 post-mortem; Mimicked post-bloating stage: day 9 post-mortem; Advanced decay stage: day 22 post-mortem; Dry-remains stage: day 75 post-mortem.
