In a field experiment, addition of whole milk 20 percent, whole egg homogenate 10 percent, Ranipal 0.5 percent, RobinbIue 0.5 percent and cotton seed oil 5 percent to nuclear polyhedrosis virus (NPV) in ULV sprays effectively controlled the gram pod borer Heliothis armigera (Hbn.) on chickpea, reduced the damage to pods and increased the yield significantly. The virus was applied three times with a controlled droplet applicator. Addition of crude sugar to NPV gave the highest yield; milk, whole egg homogenate and cotton seed oil being equally effective. In two other experiments, the different adjuvants tested could not Improve the efficacy of the virus and prevent the damage and loss in yield since the larval population at the time of spraying consisted mostly of grownup stages.Keywords

Studies on "In vitro screening of okra germplasm/ accessions against sucking pests" were undertaken at Agricultural College and Research Institute, Madurai. Thirty okra accessions were screened against sucking pests' viz., aphids, jassids, and whiteflies. The results showed that accessions IC 15027 showed resistant level, IC 90202, IC 90203, IC 90213, IC 90214 found to be moderately resistant to sucking pests.Keywords
Screening, Okra, Sucking Pests, Germplasm, Resistance.
