摘要

摘要植物次生代谢物可以影响昆虫的取食，但反应是物种特异性的。铁氧酮- a(甲酰化间苯三酚)已被证明可以抑制几种脊椎动物和无脊椎食草动物的摄食。为了研究sideroxylonal-A是否会影响叶锯蝇(Perga affinis affinis)幼虫的摄食，我们给含有不同浓度的sideroxylonal-A的桉叶幼虫喂食，并测量了草产量作为摄食的指标。我们发现:(1)至少80%的被幼虫摄食的sideroxylonal-A储存在憩室中;(2)以粪排出的少于1%;(3)喂饲不受铁氧酮- a浓度的影响;(4)幼虫在寄主叶片上产草量大于在非寄主叶片上产草量。

The effect of sideroxylonal-A on feeding of steelblue sawfly, Perga affinis affinis Kirby (Hymenoptera : Pergidae), larvae

Abstract. Plant secondary metabolites can affect insect feeding but responses are species-specific. Sideroxylonal-A (a formylated phloroglucinol) has been shown to inhibit feeding in several vertebrate and invertebrate herbivores. To investigate whether sideroxylonal-A affected feeding in sawfly larvae, Perga affinis affinis, we fed larvae eucalypt leaves containing various concentrations of sideroxylonal-A, and measured frass production as an indicator of consumption. We found that: (1) at least 80% of the sideroxylonal-A ingested by larvae was stored in the diverticulum; (2) less than 1% was excreted in frass; (3) feeding was unaffected by the concentration of sideroxylonal-A; and (4) larvae produced more frass on natal host leaves than on non-natal host leaves.

期刊介绍： Australian Journal of Zoology is an international journal publishing contributions on evolutionary, molecular and comparative zoology. The journal focuses on Australasian fauna but also includes high-quality research from any region that has broader practical or theoretical relevance or that demonstrates a conceptual advance to any aspect of zoology. Subject areas include, but are not limited to: anatomy, physiology, molecular biology, genetics, reproductive biology, developmental biology, parasitology, morphology, behaviour, ecology, zoogeography, systematics and evolution. Australian Journal of Zoology is a valuable resource for professional zoologists, research scientists, resource managers, environmental consultants, students and amateurs interested in any aspect of the scientific study of animals. Australian Journal of Zoology is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
