Host range of Ceutorhynchus assimilis (Coleoptera: Curculionidae), a candidate for biological control of Lepidium draba (Brassicaceae) in the USA
Ceutorhynchus assimilis has been selected as a potential biological control agent of Lepidium draba, which is a Eurasian invasive weed in North America. Preliminary studies indicated specificity of… Expand
Biology of Larinus curtus Hochhut (Coleoptera: Curculionidae), a European Weevil for Biological Control of Yellow Starthistle Centaurea solstitialis L (Asteraceae), in the United States
Abstract The biology of the weevil Larinus curtus Hochhut was studied in the field in northern Greece and in the laboratory in Rome, Italy, and in Thermi, near Thessaloniki, Greece. The species is… Expand
Notes on the biology of Larinus minutus Gyllenhal (Col., Curculionidae), an agent for biological control of diffuse and spotted knapweeds
Abstract: The weevil, Larinus minutus oviposits in open flowers of diffuse and spotted knapweed [Centaurea diffusa and C. maculosa (Asteraceae)] and the larvae feed on developing achenes. The species… Expand
Preliminary studies on the biology and host specificity of Aceria salsolae DeLillo and Sobhian (Acari, Eriophyidae) and Lixus salsolae Becker (Col., Curculionidae), two candidates for biological…
Abstract: Preliminary studies on the biology and host specificity of the mite, Aceria salsolae DeLillo and Sobhian, and the weevil, Lixus salsolae Becker, were carried out in 1996 and 1997. The mite… Expand
A new species of Cecidophyes (Acari: Eriophyidae) from Galium aparine (Rubiaceae) with notes on its biology and potential as a biological control agent for Galium spurium
Abstract A new species, Cecidophyes rouhollahi, is described from Galium aparine L. in Europe. This species closely resembles C. galii and causes the same symptoms attributed to C. galii (leaf edge… Expand

Phytophagous insect species associated with flower heads of yellow starthistle (Centaurea solstitialis L.)
The larvae of about 20 phytophagous species exploit heads of Centaurea solstitialis in the Mediterranean region. Host ranges, life histories and distribution of the more important species of the C.… Expand
Safety assessment and potential of Cecidophyes rouhollahi (Acari, Eriophyidae) for biological control of Galium spurium (Rubiaceae) in North America
Abstract: Galium spurium L. (Rubiaceae), native to Europe, is an increasingly serious annual weed of cultivated crops in the prairie provinces of Canada. The gall mite Cecidophyes rouhollahi Craemer… Expand
