It is based on surveys and light trap moth samples collected last summer and fall. He points out that intensive research carried out by federal research stations in Western Canada, over the last few years, has made it possible to accurately forecast the likelihood of Bertha armyworm infestations. He reports that the same surveys and light trap samples indicate that rapeseed growers should not experience any problems with either clover cutworms or alfalfa loopers. However, because little is known about the habits of these insects in Alberta, there is always a chance of 'spotty' infestations arising in any year. rape crops are the diamond-backed moth and the beet webworm. Both are unpredictable. The diamond-backed moth is unpredictable because it migrates to Alberta from the United States, and the beet webworm is unpredictable because knowledge is lacking on its over-wintering mortality. The two moth-type insects that could cause a problem in (continued) 9 EA'sPn BV TUC PA»JHi iMi^ATinMC" nn A Mru A i r> i~ n t a nrn»nTiirMT at Arninn Ti IDL.
