Pfister, Aude-Laurence

Mémoire de diplôme HES : Haute Ecole Arc Conservation-Restauration, 2008.

The presence of biocides in the process of protecting natural history collections from pest attacks can lead to health problems and can also have effects on the materials of specimen. This essay attempts to study the influence of pesticides on the conservation of naturalia, which are made of composite organic materials.

Effects of reduced rates of two insecticides on enzyme activity and mortality of an aphid and its lacewing predator

Booth, L. H. ; Wratten, S. D. ; Kehrli, Patrik

In: Journal of Economic Entomology, 2007, vol. 100, no. 1, p. 11-19

By applying insecticides at lower rates of active ingredients per unit area, survival rates of the pests' natural enemies can be enhanced, whereas pest mortality can remain high. The effects of reduced application rates of the insecticides lambda- cyhalothrin and dimethoate on the mortality of bird cherry-oat aphid, Rhopalosiphon padi (L.), and lacewing Micromus tasmaniae Walker were...
