Pennisetum clandestinum Hochst, ex Chiov. is a grass native to Central and Eastern Africa, which is reported for the Iberian and European floras from materials collected in the littoral areas of both Alicante and Valencia provinces (eastern Spain). This plant is briefly described, and some ecological and phytosociological data are also reported.

Insect Attack

Plants subjected to insect attack usually increase volatile emission which attracts natural enemies and repels further herbivore colonization. Less is known about the capacity of herbivores to suppress volatiles and the multitrophic consequences thereof. In our study, the African forage grass, Brachiaria brizantha , was exposed to ovipositing spotted stemborer, Chilo partellus , moths. A marked reduction in emission of the main volatile, ( Z )-3-hexenyl acetate ( Z 3HA), occurred following oviposition but the ratio of certain other minor component volatiles to Z 3HA was increased. While further herbivore colonization was reduced on plants after oviposition, the new volatile profile caused increased attraction of an adapted parasitoid, Cotesia sesamiae . Our results show that insect responses are dependent on the quality of volatile emission rather than merely the quantity in this multitrophic interaction.
