Abstract
The relationship between posttreatment temperatures of 15°, 20°, 25°, and 30°C and toxicity of six pesticides to adult female Phytoseiulus persimilis Athias-Henriot and Tetranychus urticae Koch were studied in the laboratory. The toxicities of cyhexatin, dicofol, propargite, citrazon, chlorobenzilate, and per-methrin were positively correlated with temperature. Except for propargite and permefhrin, P. persimilis was less susceptible than T. urticae at 15° and 20°C, but equal in susceptibility at 25° and 30°C. The results obtained may indicate a potential value of posttreatment temperature manipulation as a useful adjunct to integrated pest control programs in glasshouses. La relation entre des températures post-traitement de 15, 20, 25 et 30°C, et la toxicité de 6 pesticides pour les femelles adultes de Phytoseiulus persimilis Athias-Henriot et Tetranychus urticae Koch a été étudiée en laboratoire. La toxicité du cyhexatin, dicofol, propargite, citrazo, chlorobenzilate et permethrin s’est avérée positivement corrélée à la température. Sauf pour le propargite et le permethrin, P. persimilis était moins susceptible que T. urticae à 15 et 20°C, bien qu’également susceptible à 25 et 30°C. Les résultats obtenus suggèrent l’utilité potentielle de manipulations de la température post-traitement en tant que tactique d’appoint dans programmes de lutte intégrées en serres.This publication has 11 references indexed in Scilit:
