Abstract
The influence of predacious Mesocyclops longisetus Thiebaud on the selectio
n of oviposition sites by prey Aedes aegypti (L.) was studied under laborat
ory and field conditions. In both cases, gravid Ae, aegypti females were si
gnificantly more attracted to ovitraps containing copepods or to ovitraps w
ith water in which copepods were held previously than to distilled water. M
onoterpene and sesquiterpene compounds including 3-carene, alpha -terpinene
, alpha -copaene, alpha -longipinene, alpha -cedrene, and delta -cadinene w
ere found in hexane extracts of copepods by gas chromatography and mass spe
ctrometry analyses. These compounds may be responsible for attracting gravi
d Ae, aegypti females and may increase the number of potential prey for the
copepod.
