Abstract
The functional response of 3rd instarChrysopa carnea (Stephens) larvae feeding on 4 densities ofHeliothis virescens (F.) eggs was determined on caged cotton (Gossypium hirsutum L.).C. carnea larvae had a mean search rate of 1.08×10−5 ha/predator-day or 0.11 row-m/predator-day.
Résumé
On a déterminé la réponse fonctionnelle des 3e stades larvaires deChrysopa carnea (Stéphens) nourris sur 4 densités d'œufs d'Heliothis virescens (F.) évoluant sur coton (Gossypium hirsutum) sous cage. La larve deC. carnea possède un taux moyen de recherche journalier de: 1,08×10−5 ha ou de 0,11 m linéaire.
