摘要
Sawfly larvae of the subfamily Perginae [Pseudoperga guerini, Cereales scutellata, Perga near agnata, Pergagrapta, latreillei, Xyloperga forsuisi, Perga affinis and Pseudoperga sp.] have a diverticular pouch of the foregut in which they store an oily fluid that they regurgitate when attacked. The fluid which is an effective deterrent to ants, birds and mice, is essentially identical chromatographically to the oils of the Eucalyptus leaves on which the larve feed. The significance of the defensive use by animals of the "secondary substances" of their food plants is discussed.
