| dc.description.abstract | Studies conducted on standardization of mass rearing technique and field evaluation of pheromone of shoot and capsule borer, Conogethes spp. (Lepidoptera: Crambidae) on selected host plants brought out striking differences in the pest species. The studies on artificial diet clearly showed that the diets incorporated with castor and cardamom powders were suitable for growth and development of C. punctiferalis and C. sahyadriensis, respectively. Further studies on standardization of other ingredients in the diet like Casein 35g/ml, Vit-E capsule (1g/ml), Sorbic acid (1g/ml), Methyl parahydroxy benzoate (2g/ml) and Streptomycin sulphate (0.5g/ml) recorded higher percentage of fecundity, survivability and pupal weight of C. punctiferalis and C. sahyadriensis. Field observations on seasonal incidence of C. punctiferalis in castor fields revealed that maximum infestation occurred during November to December. The incidence of C. sahyadriensis in cardamom plantations was maximum cardamom shoot during May and in capsule during October to November which coincided with tillering and capsule formation. Similarly, in ginger plantations results revealed that maximum borer infestation occurred during September to October. The influence of abiotic factors showed that temperature and relative humidity played a major role in the incidence of these borers in cardamom, castor and ginger. Studies on standardization of trapping technique indicated that all the traps baited with pheromone lures had significantly higher catches over the traps without pheromone lures. Among four types of traps (delta, water, funnel and cross-vane trap) tested, delta trap with lure (contained (E)-10-hexadecenal (E10-16: Ald), (Z)-10-hexadecenal (Z10-16: Ald) and hexadecenal (16: Ald) at 100:8:16) proved the most effective for trapping males of C. punctiferalis moths compared to other traps. Further studies on colour and height of traps revealed that yellow delta traps installed at the crop canopy level trapped maximum moths of C. punctiferalis | en_US |
