Screening of 14 genotypes were carried out of accessions screened one accession recorded aphid population of 71.33 aphids/5 cm twig with AII 0.80. These genotype SSF-17-04 were graded as highly resistance to safflower aphid. Ten germplasm accessions recorded aphid population of 91.01-116.11 aphids/5 cm on the apical shoot length and AII ranging from 1.46 to 1.73.The seed yield of safflower varied in all the treatment plots.

The treatments with two foliar sprays of spinetoram11.70 SC and two foliar sprays of cyantraniliprole 10.26 OD were the most promising treatments which were found at par with each other, respectively. The next better treatments in order of efficacy were seed the treatment with thiamethoxam 30 FS & one foliar spray of spinetoram11.70 SC and seed treatment with thiamethoxam 30 FS and one foliar spray of cyantraniliprole 10.26 OD. The minimum seed yield was recorded in an untreated control.Visitation of various pollinators at different day hours on safflower (bees/m2/2hrs). The intensity of all the honey bee species gradually increases and reaches its peak from 10.00 to 12.00 hrs and then decline slowly. visitation of various pollinators in safflower crop.
