Abstract

Solutions of glucobrassicin (3-indolylmethyl glucosinolate) purified from foliage and sinigrin (allyl glucosinolate) elicited oviposition by the cabbage butterfly,Pieris rapae, at threshold concentrations as low as 10(-6) M. At higher concentrations, glucobrassicin elicited a faster oviposition rate and a stronger visual response to the substrate through associative learning. Solutions of 10(-5) M glucobrassicin and 10(-2) M sinigrin stimulated equally. Their enzymic hydrolysis products failed to influence oviposition. The markedly greater potency of glucobrassicin is consistent with known glucosinolate profiles of crucifers which show indolyl glucosinolates predominant in foliage.

摘要

从叶片中纯化的葡萄糖芸薹素（吲哚甲基葡萄糖硫苷）和黑芥子苷（丙烯基葡萄糖硫苷）溶液在低至 10（-6）M 的阈值浓度下即可诱引菜粉蝶（Pieris rapae）产卵。在较高浓度下，葡萄糖芸薹素通过联想学习诱使产卵速度更快，对基质的视觉反应更强。10（-5）M 葡萄糖芸薹素和 10（-2）M 黑芥子苷溶液的刺激作用相当。它们的酶解产物不能影响产卵。葡萄糖芸薹素的明显更大的效力与已知十字花科植物的葡萄糖硫苷图谱一致，该图谱表明叶中主要存在吲哚基葡萄糖硫苷。
