Host plant derived feeding deterrence towards ants in the turnip sawfly Athalia rosae
Larvae of the sawfly Athalia rosae ruficornis Jakovlev (Hymenoptera: Tenthredinidae) feed on several glucosinolate‐containing plants and have been shown to sequester the main glucosinolates ofExpand

Sequestration of Host Plant Glucosinolates in the Defensive Hemolymph of the Sawfly Athalia rosae
Interactions between insects and glucosinolate-containing plant species have been investigated for a long time. Although the glucosinolate–myrosinase system is believed to act as a defense mechanismExpand

How common is ecological speciation in plant-feeding insects? A 'Higher' Nematinae perspective
BackgroundEcological speciation is a process in which a transiently resource-polymorphic species divides into two specialized sister lineages as a result of divergent selection pressures caused byExpand

Sequestration ofVeratrum alkaloids by specialistRhadinoceraea nodicornis konow (Hymenoptera, Tenthredinidae) and its ecoethological implications
The larvae of the specialist sawflyRhadinoceraea nodicornis Konow (Hymenoptera, Tenthredinidae) store in their hemolymph ceveratrum alkaloids originating from the host plantVeratrum album L.Expand

Invertebrate and avian predators as drivers of chemical defensive strategies in tenthredinid sawflies
BackgroundMany insects are chemically defended against predatory vertebrates and invertebrates. Nevertheless, our understanding of the evolution and diversity of insect defenses remains limited,Expand

Anti-predator defence mechanisms in sawfly larvae of Arge (Hymenoptera, Argidae).
Larvae of the sawfly Arge (Hymenoptera, Argidae) are exposed to predators such as ants. Their defence mechanisms, which have been almost unstudied, were investigated by behavioural observationsExpand

Volatiles emitted by apple fruitlets infested by larvae of the European apple sawfly
Abstract The effect of infestation by larvae of the European apple sawfly ( Hoplocampa testudinea ) on the emission of volatiles from apple fruitlets was investigated. Healthy apples emitted a blendExpand

Why does the larval integument of some sawfly species disrupt so easily? The harmful hemolymph hypothesis
Abstract. The larvae of several sawfly species belonging to the Tenthredinidae (Hymenoptera) have such a low mechanical resistance in the integument that slight mechanical damage to the integument isExpand

Injection of venom into an insect prey by the free hunting spider Cupiennius salei (Araneae, Ctenidae)*
For the generalist spider Cupiennius salei, each particular predator-prey interaction could be related to obligatory behavioural patterns. The injection of venom by the spider was studied in relationExpand

Sequestration of Furostanol Saponins by Monophadnus Sawfly Larvae
Sawfly larvae of the tribe Phymatocerini (Hymenoptera: Tenthredinidae), which are specialized on toxic plants in the orders Liliales and Ranunculales, exude a droplet of deterrent hemolymph uponExpand
