Host Odor Perception in Phytophagous Insects
Annual Review of Entomology, 1986Phytophagous insects show specialized feeding habits. In general, each species feeds on a restricted range of taxonomically related plant species and in addition limits its feeding to particular plant parts. Most studies on insect-plant rela tionships concern pest species in agricultural systems, which do not show the stability of the insect's ...

Plant Architecture and the Diversity of Phytophagous Insects
Annual Review of Entomology, 1983In general, trees have richer insect faunas than herbs. This familiar observa tion is but one of several ways in which "plant architecture" and insect species diversity are correlated. In this review I explore the nature of these correlations and ask how they are produced.

Substances antiappétantes pour insectes phytophages
Biochemical Systematics and Ecology, 1986Abstract Twenty-two diversely substituted butadiynes have been tested for their insect antifeeding activity against Mythimna unipuncta, Spodoptera littoralis and Leptinotarsa decemlineata . The results in form of PA 50 (50% feeding of reference test) were submitted to Hansch linear regression analysis.

Nutritional Methods for Phytophagous Insects
The Canadian Entomologist, 1964In biochemical studies of resistance of plants to insects knowledge of the nutritional needs of the insect is required. Some methods that have been developed or were adapted from studies with large animals are displayed.Larvae of the pale western cutworm, Agrotis orthogonia Morr., have been reared on diets prepared from wheat sprouts that have been ...

Ecological speciation in phytophagous insects
Entomologia Experimentalis et Applicata, 2009AbstractDivergent natural selection has been shown to promote speciation in a wide range of taxa. For example, adaptation to different ecological environments, via divergent selection, can result in the evolution of reproductive incompatibility between populations.

Phytophagic or Biological Races in Insects
Nature, 1927I HAD no desire to enter into any controversial discussion with Dr. Heslop Harrison (whose letter in NATURE of April 16, p. 562, 1 regret not to have seen earlier), either in regard to his experiments or the conclusions he draws from them; I sought only to obtain some explanation of an alleged new principle in evolution, since anything that deserved ...
