Abstract:
The potency of novaluron on laboratory susceptible and field strains of S. littoralis resembles that of chlorfluazuron and both compounds are about 20-fold more potent than teflubenzuron. No appreciable resistance to novaluron or chlorfluazuron was observed in a field strain of Spodoptera littoralis collected from cucumber field in the central part of Israel. On the other hand, the field strain showed a mild resistance of about 4-fold to teflubenzuron as compared to the laboratory susceptible strain. A very resistant colony of Bemisia tabaci to pyriproxyfen (1,200- to 2,000-fold) showed no appreciable cross-resistance to novaluron. Two field colonies of B. tabaci pressurized with acetamiprid or thiamethoxam for 22 generations, resulting in a 30-to 50-fold resistance to acetamiprid and thiamethoxam, has no cross-resistance to novaluron. The above results are of special interest, indicating a possible alternation between novaluron, pyriproxyfen, and neonicotinoids in insecticide-resistance management programs aiming at preventing resistance development to these novel groups of insecticides against important pests such as whitefly and lepidopteran species. © 2003 Wiley-Liss, Inc.
