 interruptor (Gravenhorst). Conn., N. Y., N. J., Ont., Mich.; Europe. Ecology: Arthur et al. 



(1964) have shown that T. interruptor is cleptoparasitic upon Orgilus obscurator (Nees). 

 Introduced. Host: Rhyacionia buoliana (D. and S.). R. buoliana was the target host for 

 introductions in North America; it was not learned until after T. interruptor was 

 estabhshed that it almost exclusively oviposits into R. buoliana larvae which have 

 already been parasitized by 0. obscurator and develops at the expense of the latter. 

 Therefore it appears that T. interruptor is detrimental with respect to control of R. 

 buoliana because it limits the effectiveness of 0. obscurator. Walkley's (1967) Idaho 

 record for this species was based upon a misidentified specimen.
