TI  - Plant-derived pyrrolizidine alkaloid protects eggs of a moth (Utetheisa ornatrix) 
      against a parasitoid wasp (Trichogramma ostriniae).
PG  - 9029-32
AB  - Pyrrolizidine alkaloid (PA), sequestered by the moth Utetheisa ornatrix from its 
      larval food plant, is transmitted by both males and females to the eggs. Males 
      confer PA on the female by seminal infusion, and females pass this gift, together 
      with PA that they themselves procured as larvae, to the eggs. Here we show that 
      PA protects the eggs against parasitization by the chalcidoid wasp, Trichogramma 
      ostriniae. Eggs laid subsequent to a first mating of an Utetheisa female receive 
      most of their PA from the female. The amount they receive from the male is 
      insufficient to provide for full protection. However, female Utetheisa are 
      promiscuous and therefore likely to receive PA on a cumulative basis from their 
      male partners.
