L., which have recently caused injury to barley, have now
disappeared, up to 100% of the larvae being found parasitised
by a Diapriid, Spilomicrus sp. Swedes were attacked by
'hrips angusticeps Uzel, Plutolia macvlipennis Curt:. (cruciferntrum
Zell.), and Pieris spp., and carrots by Trioza v iridula

by Apan tolos glomer tus I. and the pupae by Pteromalus puparum

up to about 40 eggs in the host; the larvae lived within it
for 1 4 days , an( then eme rged t pupat Ie . The papal s t age
