Carbohydrate suppresses parasitization and induces egg retention in Trichogramma
Biocontrol Science and Technology 7 (2), 271-274
Abstract: The influence of carbohydrate (honey) on host acceptance and egg retention was studied in adult Trichogramma principium. The presence of honey reduced the percentage of ovipositing females and the mean number of eggs laid during 2 days. Consequently, in mass rearing, when Trichogramma is usually presented to factitious hosts for a short time, providing wasps with carbohydrate may decrease progeny production. The mean number of mature ovarial eggs in non-ovipositing females was much higher than in ovipositing females in both fed and starved wasps. The adaptive role of the positive correlation between food supply and egg retention in Trichogramma is discussed.
