Abstract
An investigation regarding the side-effects of two insecticide application strategies has been carried out. Two chemical control programmes for codling moth (Cydia pomonella L.) and for the main leafroller species (Pandemis cerasana Hb.) have been compared. One programme (“soft”) based exclusively on tebufenozide applications and the other one (conventional) based on traditional insecticides use (the exclusively use of tebufenozide was chosen only for experimental requirement, without considering the resistance management). The study has been carried out in the Ferrara District (Italy) on a pear orchard (cv. Abbè Fétel and Bartlett) in the 1998-99-00 years. A randomised block design with four replicates was used to compare the two different chemical control programmes. For sampling visual and inventory methods (depending from the insect species and the developmental stage) were used. The main pest species sampled were C. pomonella L., P. cerasana Hb., Cacopsylla pyri L. and Quadraspidiotus perniciosus (Comst.), while Anthocoris nemoralis (F.), coccinellids and syrphids were the beneficial ones. The results showed the reliability of the control strategy based on tebufenozide (no difference with regard to damaged fruits in comparison with the traditional one). This strategy gave smaller side effects on the beneficials, mainly regarding A. nemoralis young larvae. It has been possible to measure the lower insecticide use: both in quantitative and qualitative terms (toxicological classes).I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
