Parasitism by Meteorus rubens on Agrotis ipsilon as affected by supplementary food and kairomone, field studies
Anzeiger für Schädlingskunde, Pflanzenschutz, Umweltschutz 70 (6), 117-119
Abstract: Field experiments in clover field showed that releasing of 10 mated M. rubens females/m2; increased parasitism among A. ipsilon larvae from 16.7% at 0 to 43,3% after 10 days. Also, releasing 10 females/m2 after spraying 3% molasses in tomato field increased parasitism from 4% at 0-day to 27.5% after 10 days among A. ipsilon larvae. Spraying molasses and kairomone together on maize plants, increased markedly the rate of parasitism among S. cretica larvae comparing with parasitism obtained when each of them was sprayed alone. The release of M. rubens in a rate of 10 females/m2 after spraying molasses and kairomone induced a significant increase in the rate of parasitism among S. cretica larvae after 10 and 15 days compared to releasing 3 or 4 females of the parasitoid. A significant increase in parasitism among S. cretica larvae on tomato after 10 and 15 days was recorded when M. rubens was released at the rates of 5 and 10 females/m2, after spraying molasses and kairomone, compared to other treatments.
