| Popis: | The diamondback moth, Plutellaxylostella (Lepidoptera; Plutellidae) is one of the most notorious and cosmopolitan insect pests of brassica crops around the world. P. xylostella may causes 90% yield losses in brassica crops . Various control measures have been adopted to manage this pest; however, the most effective control method is the use of synthetic chemical insecticides. Overuse of insecticides have many adverse effects including insecticide resistance, hazardous to environment, long persistency, interfere with food chain. There is an urgent need for alternative control measures which should be effective, environmental friendly and economically safer. Bio pesticides include plant extracts and green synthesized nano-based insecticides are among these measures, which can be useful for the management of P. xylostella . Less work has been carried out on the use of green synthesized plant products against P. xylostella . Therefore, current study has been planned to evaluate the toxicity of plant extracts and green synthesized nano-based plant products against P. xylostella . Eight plants extract (neem, bakain, bitter-gourd, clove, eucalyptus, dathura, garlic and ginger) and their nano-based products (green synthesis silver nanoparticles) were applied in different concentrations against 3 rd larval instars of P. xylostella . Mortality were recorded after 24, 48 and 72 hours of application of treatments. Corrected mortality was calculated using Abbot’s formula and LC 50 values were calculated. |
