Última Foliar application of microdoses of sucrose to reduce codling moth Cydia pomonella L. (Lepidoptera: Tortricidae) damage to apple trees Organic Eprints Arnault, Ingrid; Lombarkia, Nadia; Ondet, Sophie-Joy; ROMET, L.; Brahim, Imene; Meradi, Rahma; Auger, J; Derridj, Sylvie. Abstract BACKGROUND The effects of foliar applications of microdoses of sucrose to reduce the damage by the codling moth have been reported from nine trials carried in France and Algeria from 2009 to 2014. The activity of sucrose alone was assessed by comparison with an untreated control and some treatments with the Cydia pomonella granulovirus or a chemical insecticide. The addition of sucrose to these different treatments was also investigated. RESULTS The application of sucrose at 0.01% reduced the means of infested fruits with a value of Abbott's efficacy of 41.0 ± 10.0%. This involved the induction of resistance by antixenosis to insect egg laying. Indeed, it seems that acceptance of egg laying on leaves treated with sucrose was reduced. The...

Organic Eprints ROMET, L.; SEVERAC, G.. Aprés avoir été testée, sur un site en 2005 et neuf en 2006, la technique de protection physique des vergers de pommier contre le carpocapse nommée "Alt'Carpo" a été adoptée en vraie grandeur dans 15 vergers provençaux en 2007, et des tests complémentaires réalisés par ailleurs. Le suivi des 15 vergers a confirmé l'efficacité de la protection mono-rang (un filet par rang de pommier), et montré l'effet protecteur anti-grêle et ...coupe-vent. Un test en grande parcelle a comparé la maille "4 x 4" choisie sur les 15 vergers à celle d'un filet anti-grêle classique (plus large). La première a semblé meilleure, mais divers facteurs avaient handicapé le filet anti-grêle. Un test en grande parcelle a comparé les systèmes mono-rang et mono-parcelle (un seul filet...
