AbstractBucculatrix parthenica Bradley sp. n., a moth native to Mexico, is described. It has been released and established in Queensland, Australia, as a biological control agent for its host plant, Parthenium hysterophorus. The moth oviposits on leaves of its host. First and second instar larvae are leaf miners, and later instars feed externally on the leaves. The life cycle occupies about 25 days under field conditions. B. parthenica was narrowly oligophagous in host-specificity tests. In Mexico the insect is scarce but in Queensland it has become abundant enough to cause extensive defoliation of its host plant at some sites. Its rapid increase in Queensland is attributed to the absence of parasitism.

The gall midge Cystiphora sonchi (Bremi) has been released and established in Alberta and other Canadian provinces as a biological control agent for the introduced weed perennial sow-thistle (Sonchus arvensis L.) (Peschken et al. 1989). Cystiphora sonchi oviposits in the expanding leaves of S. arvensis (DeClerck-Floate and Steeves 1995), where the-larvae form pustule galls, each containing a single larva. They pupate in a cocoon in the gall or sometimes in the soil after exiting from their galls. Adults are short-lived (usually 1 day or less) and do not feed (Peschken 1982). Under field conditions in Alberta, C. sonchi produces three generations a year (Peschken et al. 1989)
