Armadillidium vulgare

Additional examples of isolated natural repellents include the compounds sandaracopimarinol and (15,6i )-2,7(l4),10-bisabolatrien-l-ol-4-one isolated and identified from Cryptomeria japonica as repellents against Armadillidium vulgare which is well known as an unpleasant household pest and as a vegetable pest in Japan (Fig. These compounds strongly repelled A. vulgare when they were combined, although each compound alone did not show any activity.

The composition and biosynthesis of chitin have been studied in insects such as mosquitoes, cockroaches, honeybees, silkworms. Drosophila melanogaster, Extatosoma tiaratum, Sipyloidea sipylus in terrestrial crustaceans such as Armadillidium vulgare, Porcellio scaber, and in nematodes (Anantaraman and Ravindranath 1976, Carlberg 1982, Veronico et al. 2001, Nemtsev et al. 2004, Moussian et al. 2005, Tauber 2005, Paulino et al. 2006, Hild et al. 2008). The composition and structure of their organic matrices are different from each other.

In a study of an isopod Armadillidium vulgare) in California, Paris and Sikora (196S) tagged the forbs, Vida sativa, Silybum mariammy and Picris echioides, each in separate plots, with H3 P04 in leaf axils with a capillary pipette. Periodic samples of plants and isopods were collected and analy for radioactivity with a GM detector. The investigators concluded that it was feasible to use radiotracers in a study of trophic relationships in these cryptozoans.
