Both primary and secondary plant compounds can play the role of kairomone in host finding and acceptance by herbivores. Among these, a new class of nortropane polyhydroxylated alkaloids, the calystegines, isolated from different species belonging to the family of Solanaceae and in potato, where the main constituents are the calystegines A3 and B2, have been tested on Colorado potato beetle and potato tuber moth.


Species 1: Lepidoptera Gelechiidae Phthorimaea operculella (Potato tuberworm)
Species 2: Coleoptera Chrysomelidae Leptinotarsa decemlineata (Colorado potato beetle)
Keywords: Kairomone, Resistance
