“…Setae are considered a rich source of allergens (Lamy et al, 1986;Rodriguez-Mahillo et al, 2012). These enter the skin at the site of setae penetration, either through direct contact with live or dead larvae or as a result of wind dispersal (aero-mediated contamination), which can occur over considerable distances and lead to an immune response in infected people and animals (Artola-Bordás, Arnedo-Peña, Romeu-García, & Bellido-Blasco, 2008;Battisti, Larsson, & Roques, 2017;Bonamonte, Foti, Vestita, & Angelini, 2013;Julienne et al, 2015;Kaszak, Planellas, & Dworecka-Kaszak, 2015;Moneo et al, 2015;Pouzot-Nevoret et al, 2017;Rodriguez-Mahillo et al, 2012;Vega et al, 2011Vega et al, , 2003.…”

The pine processionary moth, Thaumetopoea pityocampa, causes serious defoliation to Cedrus, Pinus and Pseudotsuga trees, as well as health problems in humans, pets and farm animals due to their urticating hairs. Environmentally friendly strategies for the management of T. pityocampa include: removal of egg batches, removal of nests, trapping of migrant larvae, spraying microbial or Insect Growth Regulator (IGR) insecticides and biocontrol, as well as pheromone‐based adult trapping and mating‐disruption. In the present paper, results on innovative technology for the control of T. pityocampa infestation using pheromone mass‐trapping are reported. Two 1‐ha plots were identified in the study area (central‐south Italy), a pine woodland recreational site growing Pinus halepensis. In the experimental plot (MT‐plot), 10 G‐traps (funnel trap type) baited with (Z)‐13‐hexadecen‐11‐ynyl acetate sex pheromone component were placed for mass‐trapping of adults; the other plot was used as a control‐plot (C‐plot). The T. pityocampa population was monitored using the two central traps in the MT‐plot and two traps positioned in the C‐plot. In addition, the winter nests made by T. pityocampa larvae overwintering on pine trees were counted. After 2 years of mass‐trapping, the number of adults trapped by the monitoring pheromone traps decreased in the MT‐plot, but not in the C‐plot, whereas the number of nests decreased in both plots. Statistical results highlighted significant differences in trap catches between the two plots but not between years. In the case of nests, differences among plots were not significant before the mass‐trapping, but significant after 1‐year treatment. According to our results, the mass‐trapping technique is able to reduce T. pityocampa infestations. This pheromone method can be applied in combination with other control systems in the context of integrated pest management in recreational areas.

“…This caterpillar is considered one of the main forest pests and is present in extensive regions of central Asia, northern Africa and southern Europe. Reports on the toxicity of this insect can be found in medical and veterinary literature. Most cases are European or Indian, but toxicity by similar lepidopters (an order of insects that includes butterflies and moths) has also been reported in Australia…”

“…Pathogenesis is attributed to the thousands of microscopic hairs covering the body of the caterpillar, which constitute ‘airborne weapons’. The damage they produce is due to the mechanical effect of the harpoon‐shaped hairs, direct toxicity of the thaumetopoein toxin present inside the setae, and an allergic immunoglobulin E‐mediated reaction to various caterpillar proteins …”

A Review of Corneal Endotheliitis and Endotheliopathy: Differential Diagnosis, Evaluation, and Treatment

et al. 2019

The corneal endothelium plays an integral role in regulating corneal hydration and clarity. Endotheliitis, defined as inflammation of the corneal endothelium, may disrupt endothelial function and cause subsequent visual changes. Corneal endotheliitis is characterized by corneal edema, the presence of keratic precipitates, anterior chamber inflammation, and occasionally limbal injection, neovascularization, and co-existing or superimposed uveitis. The disorder is classified into four subgroups: linear, sectoral, disciform, and diffuse. Its etiology is extensive and, although commonly viral, may be medication-related, procedural, fungal, zoological, environmental, or systemic. Not all cases of endothelial dysfunction leading to corneal edema are inflammatory in nature. Therefore, it is imperative that practitioners consider a broad differential for patients presenting with possible endotheliitis, as well as familiarize themselves with appropriate diagnostic and therapeutic modalities.
