Pest Description

False chinch bugs can occur in large numbers during mild, dry winters. Fall infestations of false chinch bugs could cause stand losses. Research from Colorado shows that severe damage can occur if false chinch bugs infest racemes during bloom and early pod fill. Based on this work, it is suggested that fields should be treated with a registered insecticide if 5 to 10 false chinch bugs occur on flowering racemes, and if 10 to 20 false chinch bugs occur on racemes during early pod set. False chinch bugs are common in ripe fields of canola, but damage rarely occurs once seed is fully formed.
