Studies on the characteristics of parasitism of Plutella xylostella (Lep.: Plutellidae) by a larval parasite Diadegma semiclausum (Hym.: Ichneumonidae)



Studies on the characteristics of parasitism of Plutella xylostella (Lep.: Plutellidae) by a larval parasite Diadegma semiclausum (Hym.: Ichneumonidae)



Entomophaga. 1994( ); 393-4: 397-406



Laboratory experiments were conducted to study the characteristics of parasitism of diamondback moth,Plutella xylostella (L.), a worldwide pest of crucifers, by a larval parasite,Diadegma semiclausum Hellen. Results showed that the greater the host larval density, the lesser was the percentage of larvae parasitized. The area of discovery decreased with increasing parasite density, but k-value remained practically unchanged. Parasitism reduced food consumption in parasitised larvae. No difference was observed in duration of larval instars between the parasitized and healthy larvae. As the frequency of superparasitism increased, the proportion of production of female progeny also increased. Presence of parasite larva within the host larva deterred superparasitism greater than the presence of parasite egg. Presence of larva of eitherD. semiclausum or another larval parasite,Cotesia plutellae Kurdjumov, within host larva deterred multiparasitism by either species greater than the presence of egg of either parasite species.Diadegma semiclausum was much more aggressive thanC. plutellae in parasitisingP. xylostella larvae.
