The occurrence and control of the bruce spanworm in the Okanagan Valley, 1972
A minor outbreak of the Bruce spanworm, <i>Operophtera bruceata</i> (Hulst), occurred in fruit orchards of the Okanagan Valley in 1972. The heaviest infestations were limited to orchards where prebloom sprays for the fruittree leafroller,<i> Archips argyrospilus</i> (Walker), were neglected for two or more seasons. Prebloom applications of azinphosmethyl, diazinon or endosulfan at tight cluster bud to pink bud stage on apple gave good control. Apple, pear, cherry, apricot and plum were attacked
Predation by carpenter ants: A deterrent to the spread of cinnabar moth
Cinnabar moth, an introduced biological control agent for tansy ragwort, suffers heavy predation by carpenter ants in recently logged areas of Oregon. We suggest that this mortality factor will reduce the spread of Cinnabar moth, thus preventing it from attacking a major seed source of tansy ragwort and reducing its potential as a biological control agent. Single larvae escape predation by ants more often than those in groups which suggests that carpenter ant predation may select for larval dispersal
