    Notes: A powdery mildew (Erysiphe sp.) was found on the upper surfaces of leaves of a glasshouse-grown aubergine (Solanum melongena) crop in West Sussex during Autumn 1992. It could be readily transferred to tomato (Lycopersicon esculentum) and tobacco (Nicotiana tabacum), but produced restricted growth and sporulation on cucumber (Cucumis sativus). Sweet pepper (Capsicum annuum), Chinese cabbage (Brassica campestris var. chinensis), lettuce (Lactuca sativa), chrysanthemum (Dendranthema x grandiflorum) and Nicotiana benthamiana did not show symptoms. When transferred to tomato and cucumber, the morphology of aubergine powdery mildew resembled the natural glasshouse powdery mildew on the two crops, respectively, rather than powdery mildew on aubergine. Powdery mildew from naturally infected tomato could infect aubergine directly, and also after one, but not two, generations on cucumber.

    Description / Table of Contents: Résumé Les effets secondaires de 5 insecticides, 8 fongicides et 6 herbicides sur 24 espèces auxiliaires ont été étudiés par les membres du Groupe de travail «Pesticides et Organismes utiles» de l'OILB, Organisation Internationale de Lutte biologique Section Régionale Ouest Paléarctique (SROP). Les tests ont été effectués par 24 participants appartenant à 11 pays, et selon des directives internationalement approuvées. L'insecticide buprofézine (Applaud), les fongicides triforine (Saprol), promycidone (Sumisclex), anilazine (Dyrène), triademinol (Bayfidan), hexaconazole (Anvil), tridémorphe (Calixin) et les berbicides tralkoxydime (Grasp), bentazone (Basagran) se sont révélés sans danger pour presque tous les auxiliaires. Le diflubenzuron (Dimilin) avait un effet néfaste sur les araignées et les larves d'insectes prédateurs. Les 10 préparations restantes étaient plus toxiques et doivent donc faire l'objet d'autres essais sur les organismes utilisés.
    Notes: Abstract The side effects of 5 insecticides, 8 fungicides and 6 herbicides on 24 species of beneficial organisms were tested by members of the Working Group «Pesticides and Beneficial Organisms» of the International Organization for Biological Control (IOBC), West Palaearctic Regional Section (WPRS). The tests were conducted by 24 members in 11 countries according to internationally approved guidelines. The insecticide buprofezin (Applaud), the fungicides triforine (Saprol), procymidone (Sumisclex), anilazine (Dyrene), triadimenol (Bayfidan), hexaconazole (Anvil), tridemorph (Calixin) and the herbicides tralkoxydim (Grasp), bentazone (Basagran) were harmless to nearly all the beneficial organisms. Diflubenzuron (Dimilin) affected spiders and the larvae of predatory insects. The remaining 10 preparations were more toxic and should therefore be further tested in semi-field and field experiment on relevant organisms.
