New Pest

A new psyllid pest of ficus, Macrohomotoma gladiata (Hemiptera: Sternorrhyncha: Psylloidea), is reported for the first time from North America (California, U.S.A.). Notes on another adventive psyllid species that has been collected from ficus in California, Homotoma ficus, are given, together with a list diagnostic features that separate between M. gladiata and H. ficus.

AbstractThe North American species of Acrolepiopsis are reviewed and include six described species: A. assectella (Zeller), A. californica Gaedike, A. heppneri Gaedike, A. incertella (Chambers), A. leucoscia (Meyrick), and A. reticulosa (Braun). Acrolepiopsis liliivora Gaedike is considered a junior synonym of A. californica (new synonymy). Acrolepiopsis assectella, commonly known as the leek moth, is a recently invasive alien species in North America and a pest of the plant genus Allium, including leek, onion, garlic, and related cultivated plants. A key to species based on adults is provided, diagnostic characters including male and female genitalia are illustrated, and geographical distribution, host plants, and larval feeding pattern and damage (where known) are given. Diagnostics and illustrations are presented also for A. sapporensis (Matsumura); known as the Asiatic onion leafminer, it is very similar to A. assectella and is an invasive alien species present in Hawaii, though not in North America. Adult diagnostic characters of the genus Acrolepiopsis, the family Acrolepiidae, and the superfamily Yponomeutoidea are also provided and illustrated. DNA barcoding data (short sequences of the mitochondrial cytochrome c oxidase I gene) obtained for five of the six species revealed interspecific differences averaging 8.1%, whereas intraspecific variation was ≤ 0.16%, and provided unequivocal species separation matching morphology-based identifications.

New Pest

The cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham) [= C. assimilis (Paykull)] (Colonnelli 1993), is a univoltine species native to Europe that feeds on canola and other oilseed cruciferous plants. The adult overwinters in debris and soil outside fields and colonizes canola at the blooming stage (Dosdall et al. 2001). Eggs are laid singly into the immature pods and each larva consumes five to seven seeds before cutting a hole in the pod to wriggle out and pupate in the soil (Dmoch 1965). Yield losses are difficult to assess because the plant compensates for bud and pod injuries caused by insects or pathogens (Lamb 1989). Nevertheless, pod feeding by larvae causes much damage, as canola yields can be reduced from 15 to 35% (Homan and McCaffrey 1993). Feeding by adults can also be significant, as it can reduce oil content, seed weight, and seed germination (Buntin et al. 1995).

New Pest

In February, 1951, specimens of chrysanthemum stools received from a nurseryman near Sardis, British Columbia, were found to be injured by maggots. Examination showed dipterous larvae feeding in channels bored in the centres of the roots, crowns, and new shoots.As available literature contained no reference to an insect having this habit in chrysanthemums, material was caged for rearing. Adults began emerging on March 17, and were determined by Mr. J. F. McAlpine, Systematic Entomology, Division of Entomology, Ottawa, as Psila nigricornis Meig. This was a new record for North America.
