J. Med. Entomol. 31(4): 618-622 (1994) ABSTRACT Two aedine and three anopheline species were allowed to blood-feed to repletion, and their host-seeking behavior was measured with an olfactometer at intervals afterward. Both Aedes aegypti (L.) and Ae. albopictus (Skuse) were inhibited from subsequently seeking a host during the gonotrophic cycle, but Anopheles gambiae Giles, An. albimanus Wiedem...

The authors compared two methods of determining odour concentration under field conditions. Twelve series of odour measurements were carried out at a mink farm. Odour concentration was determined using a portable dynamic olfactometer (nasal ranger, st. croix sensory, inc.) and by approximation using the psychophysical Weber-fechner equation of S-logZ on odour intensity results. Odour concentrat...

Comparative GC/MS analysis of airborne volatiles produced by males and females of the guava weevil Conotrachelus psidii (Coleoptera: Curculionidae: Molytinae) showed the presence of a malespecific electroantennographically active compound identified as (1R,2S,6R)-2-hydroxymethyl-2,6dimethyl-3-oxabicyclo[4.2.0]octane (papayanol). Release of this compound was dependent on the photoperiod, taking ...
