Modelling water and sediment chemistry in urban canals using chironomid pupal exuviae
… chironomid assemblages in canals using pupal exuviae. The second was to understand the distribution of species, their ecology and function. The third was to find indicator taxa which were suitable to classify canals in terms of water and sediment chemistry. The fourth was to analyze potential …

Environmental and behavioral factors associated with the infestation of vineyards by larvae of grape root borer
… surface. Emerging adults leave an empty pupal exuviae at the soil surface around the vine base. There was no relationship between weekly captures in pheromone traps and pupal exuviae counts, indicating that exuviae sampling is most appropriate to assess infestations. Exuviae sampling in …

The Transfer and Fate of Cadmium and Zinc from Sewage Sludge Amended Agricultural Soil in an Arthropod Food Chain
… the sequestrationof the two metalsin the pupal exuviae. This mechanism had a greater effect on the Cd concentrations in newly emerged adult ladybirds than on Zn concentrations.In a further experiment,there appeared to be no pathway for the transfer of Cd from aphids to adult ladybirds, but a …

Aggregation, courtship, and behavioral interactions in European earwigs, Forficula auricularia L. (Dermaptera: Forficulidae)
… earwigs' proclivity for consuming carcasses and exuviae. The defensive quinones produced by F aunculana repel conspecifics. A study of the behavioral repertoire of F. aunculana showed that, contrary to previous reports, only nymphs are nocturnal. Many differences in behavior were due to gender, …

Aspects of the biology, behavior, bionomics, and control of immature stages of the cat flea Ctenocephalides felis felis (Bouche) (Siphonaptera: Pulicidae) in the domiciliary environment
… Cat flea hatched and unhatched eggs, and larval exuviae were found to be dispersed in a contagious fashion within carpet. The spatial pattern of the immature stages and remains was influenced by the habits of the pet host within a given room. First-instar larvae do not move far, if at all, from …
