(1993)The concentration of the triterpene oleanolic acid in leaves of Baccharis linearis varies at different stages of plant growth from 1.9 to 3.0 g kg-1 fr. wt. Larvae of Heliothis zea, starved with 1.4 mg of oleanolic acid ...
-
(Instituto de la Grasa, 2012-10)Policosanol comprises a mixture of long-chain aliphatic alcohols from sugarcane wax. More than 50 studies indicate that policosanol decreases serum cholesterol, while others failed to reproduce this effect. The objective ...
-
(Springer New York LLC, 1998)Volatiles from wheat and oat seedlings elicited attraction in apterae and alatae Rhopalosiphum padi. Cereal volatiles were identified by GC-MS and olfactometric tests were performed with each compound. Attraction of aphids ...
-
(2014)Sensory-motor relationships are part of the normal operation of sensory systems. Sensing occurs in the context of active sensor movement, which in turn influences sensory processing. We address such a process in the rat ...

Olfactory conditioning in mate searching by the parasitoid Aphidius ervi (Hymenoptera: Braconidae) (Cambridge University Press, 2008)Despite the fact that insect learning capacity has been broadly demonstrated, the role that this process plays during mate searching has been scarcely explored. We studied whether the sexual behaviour of a male parasitic ...
