Six provenances of P. pinnata were screened namely Raipur, Ambikapur, Jabalpur, Nainpur, Zaheerabad and Keesaragutta. Fortnightly recorded of various insect pests along with the number of their associated natural enemies were also recorded. The major insect pests were the common banded awl, leaf webber, leaf blotch miner, pod borer, leaf hopper, leaf eating beetle, mealy bugss and green lace wing, mantis along with some species of spiders were observed as the natural enemies. Maximum population of common banded awl, Hasora chromus was recorded as 17.00 larvae/twig on provenance Jabalpur. Maximum infestation (36.3%) seeds were by pod borer, Ephestia sp. was recorded on Nainpur. Population of leaf webber was maximum (3.92 larvae/twig) on Jabalpur and Keesaragutta, blotch miner (8.41 blotches/leaf) on Jabalpur, leaf eating beetles (5.25 beetles/twig) Zaheerabad, leaf hoppers 5.58 (nymphs and adults/ leaf) on Keesaragutta, mealy bugss (6.50 nymphs and adults/twig).Keywords

Studies on the seasonal incidence of mealybug, Phenacoccus solenopsis Tinsley on ashwagandha, Withania somnifera Dunal was carried out for two consecutive years during 2015-16 to 2016-17. The mealybug, P. solenopsis was observed as a major insect pest on ashwagandha. The present investigation revealed that the maximum population of mealybugs was observed during the second fortnight of December with 123.00 mealybugs per ten centimeter apical stem during 2015-16 while in 2016-17 maximum population was noticed during the first fortnight of January with 117.75 mealybugs per ten centimeter apical stem. The correlation analysis of mealybug population to meterological parameters showed that the population was highly significant and negatively correlated with maximum temperature (-0.562**) and minimum temperature (-0.837**) during 2015-16 but highly significantly negatively correlated with minimum temperature (-0.839**) in 2016-17.Keywords
