Abstract:

Incidence of (Grey semilooper) Gesonia gemma and Green semilooper (Chrysodeixis acuta) were also recorded on four dominate varieties (JS-335, JS-95-60, JS-93-05, RVS 2001-4) in soybean. Minimum of maximum temperature also shows declining trend. Rise of minimum temperature was 0.10840C from the 2009 to 2014 kharif season as compared to normal temperature. Minimum of minimum temperature shows (rising) ascending trend indicated the rise of temperature. Mean temperature difference in the period study indicated rise of 0.4620C was observed. Rainfall shows declining trend. As compared to normal rainfall it decreased by 352 mm, over the period of time. At the same time rainy days raised as 6.39 rainy days. Frequency of heavy to very heavy and extraordinary heavy rainfall shows increasing trend while frequency of light rainfall was in decreasing trend. Relative humidity increased by 3.7% in kharif as compared is normal in 2009 – 14. Decadal trend was decreasing in case of temperature, while increasing in case of rainfall and relative humidity. Incidence of Chrysodeixis acuta and Gesonia gemma was statistically at par in soybean verities JS-335, JS-9560, JS- 9305, and RVS- 2001-4. Date of arrival of monsoon and sowing date of crop, not correlated with the incidence of Chrysodeixis acuta and Gesonia gemma. Larval population of Chrysodeixis acuta was significantly correlated with the difference of sowing date and date of arrival of monsoon. However larval population of Gesonia gemma was not correlated. Larval population of Gesonia gemma increases with the increase of maximum temperature, but population of Chrysodeixis acuta decrease with the rise of maximum temperature. Larval population of Gesonia gemma was negatively correlated with minimum temperature. While it was not correlated with the larval population of Chrysodeixis acuta. Difference of maximum temperature and minimum temperature had positive impact on larval population of Gesonia gemma while no impact on Chrysodeixis acuta larval population Larval population of Chrysodeixis acuta positively correlated with relative humidity while Gesonia gemma not. Larval population of Chrysodeixis acuta was negatively correlated with rainfall while Gesonia gemma not. The larval incidence of Chrysodeixis acuta and Gesonia gemma was less when population appearance late in the season.
