Abstract
Patasson lameerei Debauche females showed significant positive responses in olfactometer studies to chewed or damaged alfalfa and red clover plant material and to the feces of adultSitona hispidulus (Fabricius) weevils. No significant responses were obtained for the host eggs or the adult weevils themselves. Intact females produced an average of 12.8 offspring when exposed to 16S. hispidulus eggs for 12 h under light. Intact females under dark conditions and females with antennae removed and under light and dark conditions produced an average of 0.8, 0.4 and 0.0 offspring, respectively. A sequence of host finding byP. lameerei females is suggested.
Résumé
Les femelles dePatasson lameerei (Debauche) ont des réactions positives significatives, en olfactométrie, en présence du luzerne mâchée ou endommagée, de trèfle rouge et de féces des charançons adultes,Sitona hispidulus (Fabricius). Elles ne manifestent pas de réponses nettes aux œufs de leur hôte ou aux adultes femelles. Les femelles intactes ont une descendance moyenne de 12,8 individus dans le cas de l'exposition d'une femelle à 16 œufs deS. hispidulus pendant 12 h à la lumière. Les femelles intactes à l'obscurité et les femelles sans antennes à la lumière ou à l'obscurité ont une descendance moyenne de 0,8, 0,4 et 0,0 respectivement. On déduit de ces essais une séquence de recherche de l'hôte en 5 phases par les femelles. deP. lameerei.
