| dc.description.abstract | The present study was undertaken to investigate the insecticidal properties of Parthenium hysterophorus against C. chinensis in the laboratory under ambient condition. Leaf, Inflorescence and stem powders were prepared and for each powder, four doses i.e. 0.5g, 1g, 1.5g and 2g per 50g chickpea seeds were separately mixed and tested for 24, 48, 72 and 96h. The test insects were reared in glass jar and tested on whole chickpea seeds. Pirimiphos-methyl and untreated check were used for comparison. The experiment was arranged in a completely randomized design in three replications. Parthenium part’s powders applied to chickpea seeds were toxic to C. chinensis that caused significant (P<0.05) mortality 24h after treatment application except stem powder at 0.5 and 1.0 g. The highest dose (2g/50g seed) inflorescence, leaf and stem powder caused 76.67, 73.33 and 56.67 per cent mortality. Similarly, all the powders induced significantly (P<0.05) lower number of F1 progeny emergence compared with the untreated chickpea seeds. However, inhibition of the F1 progeny emergence by all powders was significantly lower than Pirimiphos-methyl that resulted in 100% inhibition. The highest per cent inhibition in adult emergence was observed in case of leaf powder treated chickpea seeds (83.33) whereas the lowest in case of stem powder (52.78). The powder has also played a vital role in preventing seed weight loss. Based on the results obtained it can be concluded that the potential use of Parthenium hysterophorus parts for protection of legumes in storage. | en_US |
