Dynamics of thrips populations (Thysanoptera, Thripidae) inside and outside a rose greenhouse, monitored using yellow sticky traps
Suivi de la dynamique des populations de thrips à l'intérieur et à l'extérieur d'une serre de rosier à l'aide de pièges jaunes englués
Résumé
Thrips species Frankliniella occidentalis and Thrips tabaci [Thysanoptera: Thripidae] are two important pests of greenhouse rose crops in the south of France. Thrips catches on yellow traps placed outside reach their peak 2 to 3 weeks before the thrips infestation peaks inside the greenhouse. The rapid increase in the number of thrips captured on the traps outside the greenhouse can be explained partly by warmer temperatures. In the same way, the observation of peak catches in these traps 3 weeks earlier in 2006 than in 2005 can be also explained by higher temperatures
