Screening of Sunflower (Helianthus annuus Linnaeus) Genotypes Against the Attack of Odontotermes obesus (Rambur) (lsoptera: Termitidae)

Muhammad Aslam, Farid Asif Shaheen and Abdul Rehman

Abstract: Out of ten genotypes of sunflower (ISB 1-99, FJ 1-99, Sehala 1-99, Bahatar 1-99, Jatli 1-99, Jhelum 1-99, Dena 1-99, Hysun-33, Sohawa 1-99 and Triumph-573) screened against the attack Odontotermes obesus at Chaccanwali Deri Farms under UGC/UAAR Sunflower Project, Hysun -33 showed the highest number of termites per 30³ cm³ and also the percentage of plants damaged by this pest was highest. In Jhelum 1.99, both the number of termites as well as the percentage of sunflower plants damaged by Odontotermes obesus were the lowest. IBD 1-99 and Triumph-573 showed also high percentage of damaged plants and number of termites next to Hysun-33. The other genotypes were some what intermediate based upon the criteria mentioned. The results showed that on different genotypes, the number of termites varied and this information could help in evolving plants resistant to insect pests and thus by sowing the resistant genotypes, the dependence on the heavy use of insecticides will be minimized and ultimately the pollution problems due to injudicious use of insecticides will also be reduced. The number of termites and the damage done by them to the plants were positively correlated. It showed that as number of termites increased, the percentage of damage to plants by termites also increased.
