Abstract

Moths reared from larvae collected from sand around the bases of silver burweed (Ambrosia chamissonis [Less.] Greene) at Tsawwassen, BC were identified as the rare noctuid Lasionycta wyatti (Barnes & Benjamin) Thiarubrines, toxic secondary compounds produced by A. chamissonis, are well tolerated by these larvae. This constitutes a new host plant record for the species.

Keywords: Lasionycta; Ambrosia; thiarubrines; insect-plant chemical interaction
