“…The pest attack tolls a heavy loss (25 to 90%) in seed yield (Ahuja and Kalyan, 2002). Among the various insect pests, the sesame leaf webber and capsule borer, Antigastra catalaunalis Duponchel (Lepidoptera: Pyraustidae) was the potential constraint toproduction from seedling stage to maturity (Choudhary et al, 1987;Selvanarayanan and Baskaran, 1996). Management of this pest using insecticides though effective is discouraged in view of environmental *Corresponding author.…”

A study was conducted to identify a resistance source against sesame leaf webber and capsule borer, Antigastra catalaunalis (Dup.) among 43 sesame genotypes under field and laboratory conditions. The reaction of genotypes was categorized using 0 to 9 scoring methodology. The genotypes KMR 14 and TKG 22 were found as moderately resistant with the score of 3 and grade 5 while SI 250, ES 22 and UMA were rated to be resistant with the score 1.6 and grade 3. Among 23 genotypes tested for biophysical (non-preference) and biochemical basis (antibiosis) of resistance three genotypes viz., ES 22, UMA, SI 250 and KMR 14 were identified as less preferred for oviposition with the lowest number of eggs laid on UMA. The egg laying of A. catalaunalis was positively correlated with the trichome density on the leaf. The low growth index of A. catalaunalis in the resistant genotypes ES 22, SI 250 and UMA indicates the presence of antibiosis mechanism in the genotypes. Hence, these genotypes could be used as resistant source in hybridization programmes for transferring leaf webber and capsule borer resistance.

“…Older larvae infest the sesame capsules making an entrance hole on the lateral side and feed on the seeds inside the capsule leaving excreta on the seeds (Singh, 1983;Suliman et al, 2004;Narayanan and Nadarajan, 2005;Ahirwar et al, 2010). A. catalaunalis was the potential constraint to sesame production from seedling to maturity stage (Chaudhry et al, 1987;Selvanarayanan and Baskaran, 1996). In India, it recorded 10-71% plant infestation and 10-43.5% capsule infestation, resulting in 8.9-71.5% yield loss and 66.31% seed loss per capsule (Kumar and Goel, 1994a).…”

Field studies were conducted on the seasonal incidence of sesame capsule borer, Antigastra catalaunalis (Duponchel) (Lepidoptera: Pyralidae) and parasitism rate of its ecto-larval parasitoid Bracon hebetor Say (Hymenoptera: Braconidae) in two successive seasons of 2012 and 2013 at Ismailia Governorate. Results indicated that A. catalaunalis larvae appeared in mid-June (15 day after sowing) then increased gradually till the end of crop maturation (2 nd or 3 rd week of September). The highest percentage of infested branches, leaves, flowers and capsules was 75, 72.5, 62.5 and 47.5% respectively in the first season and 70, 70, 55 and 45%, respectively in the second season. The incidence of A. catalaunalis larvae was higher in leaves or shoots than in flowers or capsules. Ambient temperature had a positive and significant correlation with percentage of infestation by A. catalaunalis as well as number of larvae per infested branches and flowers in the first season while it had non-significant negative correlation in the second season. The mean relative humidity percentages showed non-significant negative relationship with percentages of infestation or pest incidence during the two seasons. Rate of parasitism by B. hebetor varied among plant parts in which A. catalaunalis larvae were fed on during the two seasons; being higher in the second season. Maximum parasitism percentages were 28.3, 32.5, 26.3 and 20 % in infested branches, leaves, flowers and capsules in the first season and increased to 38.7, 41.7, 35.8 and 21%, respectively in the second one.
