| dc.description.abstract | Xanthopimpla punctata. F. the solitary, potyphagous, pupal parasitoid has been so fat Considered as an insignificant species in the biological suppression-of the coconut leaf eating caterpillar, Opisina arenosella Wlk. (Lepidoptera:Cryptophasidae). Recent observations carried out in Tamil Nadu and Kerala revealed that X. punctata breeds in O. arenosella during July to December with a peak period of activity during September - October. Without uniformly dispersing in all the Opisina - infested coconut gardens, the adult parasitoids congregated in some localised tracts close to the sea, back waters or other water ways or in irrigated coconut plantations and effected a high degree of parasitism, suppressing even the dominant species of pupal parasitoids like Brachymeria nosatoi Habu. Other ichneumonid parasitoids such as Zanthopimpia sp. and X. nana nana Schulz. were not found to build up their populations in the territory occupied by X. punctata.. Host feeding is present prior to opposition, which is continued in every one to three days, through out the long life span of the female parsitoid. A method for rearing this parasitoid in the laboratory, its mating behaviour life history, intensity of natural parasitism etc. are also discussed. | en_US |
