“…The hemolymph of A. pagana and L. zonalis contains more toxic peptides than their other organs 11 . Concentrations of toxic peptides remain nearly constant across larval instars in A. berberidis 31 . Moreover, three argid and pergid species were shown to be well defended against attacks by bugs 53 that typically pierce the prey's integument to feed on internal organs.…”

“…This contrasts with sawfly-ant systems where some sawfly species are well defended whereas others are not, although being closely related and/or feeding on a same host plant 28 , 51 , 52 . In these systems, differences in defensive effectiveness are explained by distinct morphological or physiological adaptations across taxa, whereas all Arge species analyzed contain toxic peptides 9 , 31 and their hemolymph is a strong feeding deterrent that may cause ant paralysis 17 . The hemolymph of A. pagana and L. zonalis contains more toxic peptides than their other organs 11 .…”

The sawfly larvae of most Argidae and Pergidae (Hymenoptera: Symphyta) species contain toxic peptides, and these along with other traits contribute to their defense. However, the effectiveness of their defense strategy, especially against ants, remains poorly quantified. Here, five Arge species, A. berberidis, A. nigripes, A. ochropus, A. pagana, A. pullata, plus three Pergidae species, Lophyrotoma analis, Lophyrotoma zonalis, Philomastix macleaii, were tested in laboratory bioassays on ant workers mainly of Myrmica rubra. The experiments focused on short-term predator–prey interactions, sawfly survival rate after long-term interactions, and feeding deterrence of the sawfly hemolymph. The larvae of Arge species were generally surrounded by few ants, which rarely bit them, whereas larvae of Pergidae, especially P. macleaii, had more ants around with more biting. A detailed behavioral analysis of Arge-ant interactions revealed that larval body size and abdomen raising behavior were two determinants of ant responses. Another determinant may be the emission of a volatile secretion by non-eversible ventro-abdominal glands. The crude hemolymph of all tested species, the five Arge species and L. zonalis, was a strong feeding deterrent and remained active at a ten-fold dilution. Furthermore, the study revealed that the taxon-specific behavior of ants, sting or spray, impacted the survival of A. pagana but not the large body-sized A. pullata. The overall results suggest that the ability of Arge and Pergidae larvae to defend against ants is influenced by the body size and behavior of the larvae, as well as by chemicals.

“…Lophyrotomin is the main active compound in sawfly larvae, and it is an octapeptide with hepatotoxic effects [ 90 , 91 , 92 , 93 , 94 , 95 ], with poisoning cases reported in sheep, cattle, and dogs in Denmark [ 89 , 91 , 92 ]. Lophyrotomin produced by larvae is used for protection purposes, as it is noted that birds do not feed on them [ 88 , 93 ].…”

Zootoxins are produced by venomous and poisonous species and are an important cause of poisoning in companion animals and livestock in Europe. Little information about the incidence of zootoxin poisoning is available in Europe, with only a few case reports and review papers being published. This review presents the most important zootoxins produced by European venomous and poisonous animal species responsible for poisoning episodes in companion animals and livestock. The main zootoxin-producing animal species, components of the toxins/venoms and their clinical effects are presented. The most common zootoxicoses involve terrestrial zootoxins excreted by the common toad, the fire salamander, the pine processionary caterpillar, and vipers. The lack of a centralized reporting/poison control system in Europe makes the evaluation of the epidemiology of zootoxin-induced poisonings extremely difficult. Even if there are many anecdotal reports in the veterinary community about the exposure of domestic animals to terrestrial and marine zootoxins, the number of published papers regarding these toxicoses is low. Climate change and its consequences regarding species distribution and human-mediated transportation are responsible for the emerging nature of some intoxications in which zootoxins are involved. Although new venomous or poisonous animal species have emerged in regions where they were previously unreported, zootoxins produced by native species remain the main concern in Europe. The diversity of poisonous and venomous animal species and the emerging nature of certain poisonings warrant the continuous update to such knowledge by veterinary professionals and animal owners. This review offers an overview about zootoxin-related poisonings in domestic animals in Europe and also provides important information from a health perspective.
