Jassids are also scientifically known as Apheliona maculosa. The pests suck sap from the leaves and stems and have green appearance. Due to the suction of sap the margin of leaf starts becoming yellow which is a characteristic feature to identify the plants infected by Apheliona maculosa. In severe cases the foliage turns yellow and then dries and falls of. Yield loss of Glycine max due to the pests is approximately 40-45%.. When the crop age is 35-40 days then dimethoate is sprayed i.e. 30 EC @ 2ml /lit. This can be repeated after 15 days if it is required. Except that oxydemeton methyl 25 EC @2ml/lit or 0.05 % quinalphos 25 EC @ 2ml/lit can be sprayed. Although chemicals protect the yield but they are harm the environment. So for the sake of environment, bio-pesticides should be adopted now. The present study has the following extracts that may be used as bio-pesticide, i.e. Curcuma longa and Nigella sativa. At an interval of 1 week these extracts were used for 4 days for checking their efficacy against Apheliona maculosa. When results were observed it showed that Nigella sativa was more effective with mortality of about 74.35% and Curcuma longa with only 63.69% of mortality. However Curcuma longa showed fewer efficacies than Nigella sativa. Damage % on Glycine max after application of 1st , 2nd , 3rd and 4th round of Curcuma longa was 2.38, 2.67, 2.93 and 3.02 whereas for Nigella sativa it was 2.24, 2.62, 2.84 and 2.92. Percent infestation was reduced when Nigella sativa was used.
