Abstract

The spread and oviposition of Ophraella communa LeSage (Coleoptera Chrysomelidae) adults on Ambrosia artemisiifolia L. (Asterales: Asteraceae) were affected by wind direction. The densities of adults and eggs were the highest on plants located in the direction from which the wind blew. Our results suggest that oviposition preference of O. communa adults may be more dependent on the odors emitted by host plants than on their color.

 

 

Sumario

La difusión y la oviposición de adultos de Ophraella communa Le-Sage (Coleoptera: Chrysomelidae) sobre Ambrosia artemisiifolia L. (Asterales: Asteraceae) dependían de la dirección del viento. La densidad de adultos y huevos fueron los más altos en las plantas situadas en la dirección desde la que soplaba el viento. Nuestros resultados sugieren que la preferencia de oviposición de los adultos de O. communa puede ser más dependiente de los olores emitidos por las plantas hospederas que de su color.
