Abstract
Abstract A choice feeding bioassay was used to investigate the effects of artificial diet components on the repellency of larval oral secretions from western spruce budworm, Choristoneura occidentalis Freeman, to conspecific larvae. Oral secretions from insects fed on agar supplemented with linseed oil were as repellent as secretions from insects fed on complete artificial diet. Secretions from insects fed on agar alone, agar and casein, or agar and wheat germ were not significantly more repellent than distilled water; neither was linseed oil alone. Linseed oil consists of glycerides of several fatty acids, which are likely metabolized quickly in the insect gut; repellency of oral secretions could be due to any of the related fatty acids or metabolites.
摘要采用选择性饲养生物试验，研究了人工饲料成分对西部云杉budworm (christoneura occidentalis Freeman)幼虫口腔分泌物对同种幼虫的驱避作用。饲喂添加了亚麻籽油的琼脂的昆虫的口腔分泌物与饲喂完全人工饲料的昆虫的分泌物具有同样的驱避作用。单独饲喂琼脂、琼脂与酪蛋白或琼脂与小麦胚芽的昆虫分泌物的驱避效果不显著高于蒸馏水;亚麻籽油也不是唯一的。亚麻籽油由几种脂肪酸的甘油酯组成，这些脂肪酸可能在昆虫的肠道中迅速代谢;口腔分泌物的驱避可能是由于任何相关的脂肪酸或代谢物。
