Dispersal of trichogrammatoidea cryptophlebiae hymenoptera trichogrammatidae an egg parasitoid of the false codling moth cryptophlebia leucotreta lepidoptera tortricidae in an empty habitat

Dispersal of trichogrammatoidea cryptophlebiae hymenoptera trichogrammatidae an egg parasitoid of the false codling moth cryptophlebia leucotreta lepidoptera tortricidae in an empty habitat
To establish preliminary information on the dispersive ability of T. cryptophlebiae Nagaraja, an egg parasitoid of the citrus pest C. leucotreta (Meyr.), approximately 60,000 adult parasitoids were released into an empty habitat comprising a wheat-growing area of the northern Transvaal. Insects were recaptured over a period of seven days on a grid of upturned saturn-yellow sticky traps. Total recapture was very low at less than 0.1% of those released, with 78% of adults recaptured within 250 m of the release point. The maximum observed dispersive distance was 1,275 m.
