Phagostimulatory responses of third-instar larvae ofChilo Partellus to phenolic components identified in an ethyl acetate extract of the leaf whorls of 3-week-old plants ofSorghum bicolor cultivar IS 18363 were studied in no-choice bioassays. The major components in the extract were identified as 4-hydroxybenzaldehyde and 4-hydroxybenzoic acid, with 4-hydroxy-3-methoxycinnamic acid, 3,4-dihydroxycinnamic acid, and 4-hydroxycinnamic acid present in minor amounts. All but 4-hydroxycinnamic acid were stimulatory at the doses tested. 4-Hydroxybenzaldehyde was more stimulatory than other potential biogenetic analogs. Hydroxybenzoic acids generally elicited greater feeding response than cinnamic acids, and the pattern of oxygen substitution in the benzene ring was related to bioactivity.
在非选择性生物测定中研究了 3 龄幼虫对黑高粱叶片叶环提取物中鉴定出的酚类成分的取食刺激反应。提取物中的主要成分被鉴定为 4-羟基苯甲醛和 4-羟基苯甲酸，其中 4-羟基-3-甲氧基肉桂酸、3,4-二羟基肉桂酸和 4-肉桂酸含量较少。除 4-羟基肉桂酸外，所有物质在测试剂量下均具有刺激性。4-羟基苯甲醛比其他潜在生物合成类似物更具刺激性。羟基苯甲酸通常比肉桂酸引起更大的取食反应，苯环上的氧取代模式与生物活性有关。
