Pine processionary moths, Thaumetopoea wilkinsoni Tams, 1924 and Thaumetopoea pityocampa ([Denis & Schiffermüller], 1775) (Lepidoptera: Notodontidae) are among the most destructive pine pests in Mediterranean basin. Their larvae descend to the ground from the canopy in spring for pupation and rest there until late summer. Although this is the general pattern, pupal period is a plastic feature and can be prolonged for up to several years. It is considered one of several difficulties of processionary moth management as such a plasticity provides a continuous support from the underground reservoir to the pest population. This phenomenon has been known for a long time and its discovery has been attributed to Guy Démolin; renowned INRA (France) researcher. Here, we report an unnoticed researcher, Ömer Besçeli, from Turkey who published the phenomenon of prolonged diapause in the pine processionary moth earlier.

Forest Lepidoptera

AbstractParasitoids are significant enemies of many economically important insects and there is some evidence to suggest that their actions have a role in terminating the outbreaks of forest Lepidoptera populations. In this study, we examined the impact of parasitoids on the pupae of the pine processionary moth, and highlighted the presence of several parasitoid species for this developmental stage. A higher rate of parasitism was found when the pupal density in the soil was reduced, but the rate of parasitism was not influenced by pupal morphological traits or by the presence or absence of a cocoon around a pupa. Of the external factors examined, a delay in the time of descent of larvae from the trees had a positive effect on the level of parasitism. Observational data indicated that dipteran and hymenopteran were the most abundant parasitoids to emerge from moth pupae. Our study highlights the complexity of the parasitoid–host dynamics, and stresses the importance of carefully determining environmental effects on host–parasitoid relations.

Abstract T. processionea, commonly known as the oak processionary moth, is a major pest in many European countries and threatens the health of oak trees. The common and scientific names of T. processionea refer to the behaviour of the larvae to form long processions. The larvae cause severe defoliation, reducing the viability of oak trees. They also pose a risk to both human and animal health because they shed poisonous hairs, which can result in severe allergic reactions, amongst other health problems. The moth is native to central and southern Europe but is now present in almost all European countries and also in parts of the Middle East. EPPO issued a Pest Risk Analysis in 2007 for the UK in response to infestations of the species in Europe from 2006. At this time, infestations of the moth were observed on a range of oak (Quercus) species in London. The adult males are strong fliers and can fly long distances, such as from France to the UK (Evans, 2007). Host plants of this pest include many species of deciduous Quercus, and to a much lesser degree, Betula, Carpinus, Castanea, Corylus, Crataegus, Robinia and Fagus; plants commonly found in forests, woods or ornamental plantations in the UK, for example (Evans, 2007). Therefore, areas where these plants are present and offer a suitable climate for pest development are likely to be under threat from T. processionea. Various pines have been reported as hosts, but such records are suspect and are probably the result of confusion with the pine processionary (Thaumetopoea pityocampa).

Spider Bites

There are many native species of animals with the potential to cause severe disease in Portugal. Of the four clinically relevant snake species, the vipers (Vipera latastei and Vipera seoanei) are the most concerning. They can cause severe disease and require in-hospital management, monitoring and specific treatment, including the administration of anti-snake venom serum. The Malpolon monspessulanus and Macroprotodon brevis snakes cause mostly localized clinical manifestations, which do not require specific treatment. Only a minority of the spider species in Portugal possess chelicerae (mouthparts of the Chelicerata, shaped as either articulated fangs or pincers, which may contain venom or be connected to the venom glands and are used for predation or capture of food) long enough to perforate the human skin. Nevertheless, Latrodectus tredecimguttatus and Loxosceles rufescens spider bites may require specialized treatment in a hospital setting, as well as careful active symptom surveillance. Diversely, the treatment for Scolopendra cingulata and Scolopendra oraniensis centipedes’ bites is merely symptomatic. The only existing scorpion species in Portugal is the Buthus ibericus; its sting typically causes local symptoms with intense pain, and its treatment consists essentially of analgesia. The insects of the Hymenoptera order, such as bees and wasps, have the ability to inject venom into the skin. Most people present only with local or regional inflammatory response, and symptomatic treatment is usually effective. Even so, individuals with hypersensitivity to bee venom may develop anaphylaxis. Several marine species in the Portuguese coast are venomous to humans, including weeverfish (Trachinidae family), stingrays (Dasyatis pastinaca, Taeniura grabata, Myliobatis aquila), red scorpion fish (Scorpaena scrofa), cnidaria (Pelagia noctiluca, Chrysaora hysoscella, Physalia physalis) and bearded fireworm (Hermodice carunculata); treatment is symptomatic. Contact with the larvae or bristles (chitinous structures with locomotor or tactile functions) of Thaumetopoea pityocampa (pine processionary) can cause cutaneous, ocular and, rarely, respiratory reactions; its management is also symptomatic.

Typical Prey

Outbreaks of the processionary moth Thaumetopoea pityocampa (Denis & Schiffermüller, 1775), a forest pest from the Palearctic, are thought to induce a behavioral response of bats, but up to now the moth has been seldom identified as bats’ prey. Studies on bat diets suggest moths with cyclical outbreaks attract a wide array of bat species from different foraging guilds. We test whether bats feed upon T. pityocampa in the Iberian Peninsula irrespective of the predator’s ecological and morphological features. We found that seven out of ten bat species belonging to different foraging guilds contained T. pityocampa DNA in their faeces and no difference was found in the foraging frequency among foraging guilds. A different size of the typical prey or the lack of fondness for moths can explain the absence of the pest in some bat species. Moreover, the intraspecific foraging frequency of T. pityocampa also changed with the sampling site likely representing differential availability of the moth. Lack of information on flight and dispersal behavior or the tympanate nature of the adult moth complicates understanding how different foraging guilds of bats prey upon the same prey. Our data suggests that T. pityocampa is a remarkable food source for many thousands of individual bats in the study area and we anticipate that more bats besides the species studied here are consuming this moth.

Thaumetopoea Pityocampa

A lagarta do pinheiro, Thaumetopoea pityocampa, é um inseto desfolhador responsável pelo atraso do crescimento ou a morte de vários tipos de pinheiros. Além de danos ambientais a lagarta pode provocar reações cutâneas em humanos pelo contato com os pelos irritantes das larvas. Embora a dermatite ocorra entre grupos de profissionais de ar livre, afecta principalmente grupos não-ocupacionais. Os meios de transmissão compreendem o contato directo com o ninho e/ou processionária e o contato indireto com os pelos dispersos no ar. A dermatite é geralmente observada no final da Primavera, particularmente, de Março a Junho, entre os ultilizadores de parques de campismo. A erupção cutânea tem início 1-12 horas após o contato com os pêlos e apresenta-se com prurido intenso e persistente. Para além da pele, a T. pityocampa pode envolver a olhos e a via aérea, mas de forma menos frequente. Apesar dos danos consideráveis para os seres humanos e para natureza, a infestação é um problema subestimado; a literatura médica é escassa e, muitas vezes, a informação relevante é a que se refere aos meios de comunicação locais e à sabedoria popular.
