Il Cabinet d'amateur di Georges Perec

2011

In 1979 one year after the publication of La vie mode d’emploi, George Perec wrote Cabinet d’amateur. Histoire d’un tableau, in which he tells the story of a painting belonging to the genre of the cabinet d’amateur, also known as kunst- und wunderkammer. It is a collection of different paintings, usually belonging to a rich man or a notable, portrayed (once again) in a single picture celebrating the magnificence of this more or less real collection. As for the pictorial genre, so the short novel is the celebration of the images collected by George Perec in his previous masterpiece, La vie mode d’emploi. This is why I assume this work to be referable to the genre of structural homology more …

Seabirds mated for life migrate separately to the same places: behavioural coordination or shared proximate causes?

2015

Long-term pair bonds occur in diverse animal taxa, but they are most common in birds, and can last from a few years to a lifetime. In many of these species, after the reproductive season, birds migrate to distant nonbreeding grounds where they remain for several months, and until recently, little was known about whether partners maintain contact during migration. This gap in knowledge was primarily due to past methodological difficulties in tracking long-term, large-scale movements of individuals. However, the development of new animal-borne geolocation devices has enabled researchers to track movements of individuals for a year or more. We tracked the annual migrations of both members of b…

Influence of Bacterial Secondary Symbionts in Sitobion avenae on Its Survival Fitness against Entomopathogenic Fungi, Beauveria bassiana and Metarhiz…

2022

The research was focused on the ability of wheat aphids Sitobion avenae, harboring bacterial secondary symbionts (BSS) Hamiltonella defensa or Regiella insecticola, to withstand exposure to fungal isolates of Beauveria bassiana and Metarhizium brunneum. In comparison to aphids lacking bacterial secondary symbionts, BSS considerably increased the lifespan of wheat aphids exposed to B. bassiana strains (Bb1022, EABb04/01-Tip) and M. brunneum strains (ART 2825 and BIPESCO 5) and also reduced the aphids’ mortality. The wheat aphid clones lacking bacterial secondary symbionts were shown to be particularly vulnerable to M. brunneum strain BIPESCO 5. As opposed to wheat aphids carrying bacterial s…

An exceptional outbreak of Macroscytus brunneus (Fabricius, 1803) (Hemiptera: Heteroptera: Cydnidae) on Linosa island (Pelagian Islands, Sicily)

2018

An exceptional outbreak of the burrowing bug Macroscytus brunneus occurred in summer 2017 on Linosa island (Pelagian Islands, Sicily). Huge numbers of specimens, attracted to the lights of the small village, interfered heavily with human activities for almost three months. The few precedent cases reported in literature are reviewed.

Hemocytes of Rhynchophorus ferrugineus (Olivier)(Coleoptera: Curculionidae) and their response to Saccharomyces cerevisiae and Bacillus thuringiensis

2011

Originally from tropical Asia, the Red Palm Weevil (RPW Rhynchophorus ferrugineus (Olivier) is the most dangerous and deadly pest of many palm trees, and there have been reports of its recent detection in France, Greece and Italy. At present, emphasis is on the development of integrated pest management based on biological control rather than on chemical insecticides, however the success of both systems is often insufficient. In this regard, RPW appears to be one pest that is very difficult to control. Thus inves- tigations into the natural defences of this curculionid are advisable. RPW hemocytes, the main immuno- competent cells in the insect, are described for the first time. We identifie…

Plant surfaces of vegetable crops mediate interactions between chemical footprints of true bugs and their egg parasitoids.

2009

During the host location process, egg parasitoids can eavesdrop on chemical cues released from immature and adult hosts. These indirect host-related cues are highly detectable, but of low reliability because they lead egg parasitoid females to an area where oviposition is likely to occur rather then providing wasps with direct information on the presence of eggs and their location. In the host-parasitoid associations between true bugs and their scelionid egg parasitoids, female wasps perceive the chemical residues left by host adults walking on substrates as contact kairomones, displaying a characteristic arrestment posture. In this study, we demonstrated that epicuticular waxes of leaves o…
