Production of the male specific compound, 6,10,13-trimethyltetradecyl isovalerate by the predatory stink bug Eocanthecona furcellata (Wolff) was dramatically affected by rearing conditions. Male bugs kept isolated after eclosion produced an average of 1,948 ng of 6,10,13-trimethyltetradecyl isovalerate per bug, whereas male bugs reared in groups of 5-8 bugs produced an average of only 4 ng of 6,10,13-trimethyltetradecyl isovalerate per bug. Same-sex or mixed-sex pairs of bugs produced less than 50 ng per bug. Male bugs kept isolated for 1 wk and then grouped for 1 wk produced 3 ng of 6,10,13-trimethyltetradecyl isovalerate per bug, whereas male bugs grouped first and then isolated produced 135 ng of 6,10,13-trimethyltetradecyl isovalerate. A total of 11 minor components in relative amounts of less than 1% of the major 6,10,13-trimethyltetradecyl isovalerate were found in the sternal gland secretion. These included 6,10,13-trimethyltetradecanol, acetate, propionate, and butyrate esters of 6,10,13-trimethyltetradecanol, and isovalerate or valerate esters of homologs of 6,10,13-trimethyltetradecanol.
捕食性椿象Eocanthecona furcellata (Wolff)产生雄性特异性化合物6,10,13 - 三甲基十四烷基异戊酸酯的过程受到饲养条件的显著影响。羽化后单独饲养的雄虫平均每只产生1948纳克6,10,13 - 三甲基十四烷基异戊酸酯，而在5 - 8只一组饲养的雄虫平均每只仅产生4纳克6,10,13 - 三甲基十四烷基异戊酸酯。同性或异性成对饲养的椿象每只产生量不到50纳克。先单独饲养1周然后再分组饲养1周的雄虫每只产生3纳克6,10,13 - 三甲基十四烷基异戊酸酯，而先分组饲养然后再单独饲养的雄虫每只产生135纳克6,10,13 - 三甲基十四烷基异戊酸酯。在腹板腺分泌物中总共发现了11种相对含量低于主要成分6,10,13 - 三甲基十四烷基异戊酸酯1%的次要成分。这些成分包括6,10,13 - 三甲基十四烷醇、6,10,13 - 三甲基十四烷醇的乙酸酯、丙酸酯和丁酸酯，以及6,10,13 - 三甲基十四烷醇同系物的异戊酸酯或戊酸酯。
