Host Odor Perception in Phytophagous Insects

Annual Review of Entomology, 1986
Phytophagous 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 ...

Ecological speciation in phytophagous insects

Entomologia Experimentalis et Applicata, 2010
AbstractDivergent 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.

On optimal oviposition behavior in phytophagous insects.

Theoretical Population Biology, 1978
Abstract A model is developed that predicts when an insect should oviposit on a potential larval host plant when it is encountered. Optimal behavior depends upon the suitability of this plant for larval development and on the probability of finding a more suitable host in the available time.

Sympatric speciation in phytophagous insects: moving beyond controversy?

Annual Review of Entomology, 2002
▪ Abstract  Sympatric speciation is the splitting of one evolutionary lineage into two without the occurrence of geographic isolation. The concept has been intimately tied to entomology since the 1860s, when Benjamin Walsh proposed that many host-specific phytophagous insects originate by shifting and adapting to new host plant species.

Substances antiappétantes pour insectes phytophages

Biochemical Systematics and Ecology, 1986
Abstract 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.
