Phytophagous Insects on Carduus macrocephalus in Italy

Environmental Entomology, 1978
One hundred nine species of phytophagous insects from 6 orders and 33 families fed or reproduced on the thistle, Carduus macrocephalus Desfontaines, a biennial or winter annual in Italy. About ½ the species attacking this plant were polyphagous. Fifteen species were restricted to the tribe Cynareae; and another 16 species were restricted to the ...

Ecology and adaptation of phytophage insects

2009
This is the sixth of 7 articles in a dossier (special feature) on ecological engineering - in the sense of biodiversity conservation and the best and most sustainable use by humans of natural resources. It notes that while conventional farming is coming to the limits of its development, the study of the evolutionary ecology of phytophagous insects ...

Chemical ecology of oviposition in phytophagous insects

Experientia, 1989
Selection of a suitable site for oviposition by phytophagous insects is critical for successful development of the offspring. The behavioral events leading to oviposition are mediated to a large extent by chemical cues associated with potential host plants.

The function of dietary sterols in phytophagous insects

Journal of Insect Physiology, 1962
Abstract Sterol conversion by phytophagous insects has been investigated by comparing the tissue sterols of larvae with those of their food. The inability of larvae of Dermestes maculatus to reach the pupal stage in the presence of dietary β-sitosterol, clionasterol, stigmasterol, ergosterol, or brassicasterol and their strict requirement for either ...

Sympatric Speciation in Phytophagous Parasitic Insects

1975
The appearance of new insect pests on economically important plants is a well-known phenomenon to many applied biologists. In addition, populations of introduced or native insects are frequently encountered which exhibit different host preferences, but which are morphologically indistinguishable from one another (Brues 1924, Simms 1931, Mayr 1942 ...
