HOST SPECIFICITY OF TINGIS AMPLIATA (TINGIDAE: HETEROPTERA): A CANDIDATE FOR THE BIOLOGICAL CONTROL OF CANADA THISTLE (CIRSIUM ARVENSE)
Published online by Cambridge University Press: 31 May 2012
Abstract
The only confirmed host plant of Tingis ampliata H.-S. (Tingidae: Heteroptera) is Canada thistle (Cirsium arvense (L.) Scop.). For this and other reasons, T. ampliata appeared to be a promising biocontrol agent for use in Canada. However, in the laboratory, T. ampliata developed fertile eggs while feeding on the two economic plants globe artichoke (Cynara scolymus L.) and safflower (Carthamus tinctorius L.), and nymphs developed to adults on globe artichoke. Therefore, T. ampliata should not be released in Canada.
