| dc.description.abstract | The bioecology and management of groundnut pod bug (Elasmolomus sordidus) was conducted in field and laboratory at Laxmeshwar and University of Agricultural Sciences, Dharwad, respectively during 1997-98. The population of pod bug in groundnut ecosystem fluctuated between 3.10 to 12.31 per 78.53 sq.cm. Maximum of 30.22 per 78.53 sq.cm was recorded in godown. In addition to crop plants and perennial trees weed host Solanum nigrum was found to harbour the pod bug throughout the year. The average incubation and nymphal period encountered during the study were 7 89, 7.50, 7.32 days and 30.71, 30.53, 27.38 days on groundnut, sunflower and sesamum, respectively. The adult longevity recorded was 15.49, 15.25 and 13.33 days wrth a fecundity rate of 15.4, 15.2, 13.2 on these respective produce. Earwig (Labidura sp.) and cricket (Gryllus sp.) were two predators recorded on pod bug with the maximum population upto 9.00 per half kg of litter and 2.33 per square metre, respectively. Earwig consumed 24.26 eggs and 3.09 adults per day. A similar trend was also noticed in the predatory behaviour of cricket. Sesamum (E-8) was preferred over sunflower by recording maximum bug congregation of 28.54 for 10 days exposure period. Sesamum recorded significantly higher loss of weight and oil content in 30 days exposure compared to sunflower under free choice condition. A study on field and storage loss revealed that stack and store treated with chemical could reduce the pod damage upto 46.24 per cent. The stack treated pods recorded minimum oil reduction (7.45%) as compared stack untreated pods (23.09%). There was no significant differences among groundnut entries screened against pod bug damage. Chlorpyriphos and malathion dust were found superior in the management of pod bug causing mortality upto 90 per cent. Soil treatment with chlorpyriphos and heap treatment with botanicals or chemicals resulted better control over heap treatment alone. | en_US |
