Introdução: Ambientes urbanos como áreas verdes, praças, parques e escolas estão se tornando cada vez mais propícios ao aparecimento de animais peçonhentos, dentre eles as lagartas urticantes. Acidentes com algumas lagartas urticantes podem ser graves, podendo leva ao óbito, como no caso do gênero Lonomia. Objetivo: descrever o perfil epidemiológico dos acidentes envolvendo lagartas urticantes no município de Chapecó, Santa Catarina e identificar espécies vegetais hospedeiras destas lagartas. Metodologia: Foram coletados os dados epidemiológicos dos acidentes com lagartas urticantes registrados no período entre 2016 e 2017. Os dados foram obtidos junto ao Sistema de Informação de Agravos de Notificação (SINAN). Foram analisadas as variáveis sexo, idade, parte do corpo acometida, os meses que houve as notificações, a ocupação dos indivíduos que tiveram contato com a lagarta, local em que residem, escolaridade e a espécie da lagarta envolvida. Ainda, foram identificados os espécimes coletados pelo setor de Vigilância em Saúde Ambiental, bem como foram identificadas as plantas hospedeiras em que foram encontrados. Resultados: Foram registrados 377 acidentes envolvendo majoritariamente o sexo feminino e a faixa etária entre 20 a 49 anos. As partes do corpo mais acometidas foram o pé (17,0%), mão (12,9%) e cabeça (11,4%). Foram identificadas seis espécies de plantas associadas à ocorrência de lagartas urticantes Conclusões: O estudo contribui com informações epidemiológicas sobre os acidentes causados por lepidópteros em um município de grande porte. Ressalta-se, a importância de ampliar as pesquisas em relação às plantas hospedeiras e a divulgação dos resultados visando a prevenção de acidentes.

“…The clinical record and physical examination are essential factors for an adequate diagnosis. Patients usually consult after a not very long period of evolution after the contact with the larva of L. obliqua (28,29), reporting a clinical picture of malaise associated with burning pain at the contact site, myalgia, and occasionally high temperature, which is usually accompanied by hemorrhagic systemic manifestations (gingivorrhagia, epistaxis, ecchymosis and even digestive hemorrhages) (8,15,17,30). In some very severe cases there may even be intracerebral hemorrhage.…”

Introduction The envenomation by Lonomia species mainly occur in rural areas. The main symptom of this condition is an alteration in the clotting times and hemorrhage. However, acute kidney injury is been also identified in some case reports. Therefore, it should not be disregarded and to understand the pathophysiological mechanism, diagnosis and treatment of this clinical feature results necessary in order to expand awareness and to prevent further medical complications and death. Materials and Methods We present a case report and scoping review of the literature to characterize patients with acute kidney injury secondary to Lonomia envenomation by a case report and describing the pathophysiology, diagnosis, treatment and prognosis of patients suffering from this condition. The information was obtained from 4 databases: Medline, Embase, LILACs and Ovid. We used the following search strategy: (((“Acute Kidney Injury” [Mesh]) AND “lonofibrase” [Supplementary Concept]) OR lonomy accident) OR lonomia. Results We identified ten case reports of Lonomia spp. Envenomation, nine of them were caused by L. obliqua and one by L. achelous. A cohort study that included 37 patients who were exposed to the L. obliqua venom was also included. All patients were adults, lived in the countryside and developed acute kidney injury. Conclusions Acute kidney injury has been identified as one important clinical feature of the Lonomia envenomation. The development of this condition is mediated by various pathophysiological mechanisms. To perform an adequate diagnosis, coagulation times, fibrinogen levels, hemogram, kidney function and urinalysis should be done. The definitive treatment depends on the type of envenomation. The prognosis for these patients is not well described yet. However, our patient had a good response to the described management given.

“…Larval lepidopterans (caterpillars) use venom to deter predators. The chief symptom of envenomation is pain and/or irritation, though some caterpillar envenomations of humans are capable of causing numbness, vomiting, respiratory paralysis, and even death (Kawamoto and Kumada, 1984;Balit et al, 2003;Hossler, 2010;Maggi and Faulhaber, 2015).…”

The insects are a hyperdiverse class containing more species than all other animal groups combined-many of which employ venom to capture prey, deter predators and microorganisms , or facilitate parasitism or extra-oral digestion. However, with the exception of those made by Hymenoptera (wasps, ants and bees), little is known about insect venoms. Here, we review the current literature on insects that use venom for prey capture and predator deterrence, finding evidence for fourteen independent origins of venom usage among insects, mostly among the hyperdiverse holometabolan orders. Many lineages, including the True Bugs (Heteroptera), robber flies (Asilidae), and larvae of many Neuroptera, Coleoptera and Diptera, use mouthpart-associated venoms to paralyse and pre-digest prey during hunting. In contrast, some Hymenoptera and larval Lepidoptera, and one species of beetle, use non-mouthpart structures to inject venom in order to cause pain to deter potential predators. Several recently published insect venom proteomes indicate molecular convergence between insects and other venomous animal groups, with all insect venoms studied so far being potently bioactive cocktails containing both peptides and larger proteins, including novel peptide and protein families. This review summarises the current state of the field of entomo-venomics. 1. Multiple independent origins of venom use among insects The >5 million species of insects estimated to exist on earth today make up the majority of eukaryotic species (May, 1988; Stork, 2018). Moreover, insect diversity goes further than just vast numbers of species. Hexapods (including insects) diverged from their closest relatives, the cave-dwelling remipede crustaceans, ~479 mya, and true insects (Ectognatha) emerged ~440 mya when they diverged from the entognathous hexapods (Collembola, Diplura and Protura) (Misof et al., 2014). Since their early evolution as one of the first animal groups to adapt to terrestrial lifestyles, the insects have undergone a spectacular evolutionary radiation and today occupy a diverse array of ecological niches. Major adaptations powering this radiation include the early adoption of powered flight and copulation for sperm transfer by the early Pterygota, a group that includes all orders except Archaeognatha (jumping bristletails) and Zygentoma (silverfish). Holometabolous development-in which larvae must pass through metamorphosis to become adults which differ markedly in their morphology-probably further drove diversification by allowing a single species to occupy multiple niches at different life stages. Of the 34 extant orders, 18 are descended from a holometabolous ancestor that lived ~345 mya (Misof et al., 2014), including the hyperdiverse insectan orders Hymenoptera, Diptera, Coleoptera and Lepidoptera. Only one of the hyperdiverse orders, Hemiptera, is hemimetabolous. Alongside these major trends, a multitude of trophic strategies, mating systems and life histories evolved, entailing adaptations spanning the biochemical, morphological and behavi...
