Laboratory and Field Trials to Identify Reduced-Risk Insecticides for the Control of the Golden Twin-Spot Moth Chrysodeixis chalcites (Esper) (Lepidoptera: Noctuidae) in Banana Plantations

The golden twin-spot moth (Chrysodeixis chalcites) is one of the most important pests in banana production on Canary Islands (Spain). efficacy different biorational insecticides based bioenzyme complexes (Intruder®), plant extracts: Rutaceae and Piperaceae (Avenger®), Lauraceae (BioKnock®), cinnamon, citronella, Menta (Cinamite®), Alliaceae Solanacea (Garlitrol-Forte®), citrus (Prevam®), neem oil (Indasol®) was assessed against C. chalcites. Laboratory assays included: choice (repellent effect), no choice, contact toxicity chalcites 2nd instar larvae. highest repellent effect observed with Prevam® (85.19 ± 1.7%), followed by Garlitrol® (68.44 5.7%) Intruder® (67.54 4.3%). In assays, (0.92 0.4%), Indasol® (0.98 0.33%), (2.7 0.33%) had lowest leaf consumption. showed mortality both at 1 day 7 days post-application (20.22 2.98% 77.77 5.7%, respectively). screenhouse trial, best results for larvae mortality, fruit damage, classification quality categories after application bioinsecticide were obtained Intruder®, Prevam®, Indasol®. An economic analysis treatments also performed. this study provide successful alternatives to chemical pesticides control plants Islands.
