Aspects of the sensory physiology of the pollination of "Petunia axillaris" and mating in moth pests

Gurba, Alexandre ; Guerin, Patrick (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2013.

Compounds produced by plants have an important impact on many aspects of the biology of insects from whom plants are a particularly important source of food. As an adult, insects use chemical messages to identify and locate a suitable food source. The specificity of the host plant relationship is also crucial for healthy development of larvae. The choice of oviposition site is determinant for the...

In: Planta, 1998, vol. 207, p. 146-152

Maize (Zea mays L.) releases specific volatiles in response to herbivory by caterpillars. These volatiles are known to serve as cues for parasitic wasps to locate the herbivores. In the present study the exact time of volatile emission after simulated herbivory (mechanical damage and treatment with caterpillar regurgitant) was measured for seedlings of the cultivars "Ioana Sweet Corn" and...
