Title : Importance of physicochemical properties for the design of new pesticides.
Year : 2011
Volume : 59
Issue : 7
First Page : 2909
Last Page : 2917
Authors : Akamatsu M.
Abstract : The physicochemical properties of candidate compounds play important roles in the design of new pesticides. Pesticides must be absorbed by pests, be transported to the target site, and then interact with proteins. Hydrophobicity is very important for these processes. Log P, where P is the partition coefficient in the 1-octanol/water system, is commonly used as a hydrophobic descriptor and correlates with membrane permeation and transport. It was recently reported that permeability by the parallel artificial membrane permeation assay (PAMPA) could be used to predict human oral absorption of passively transported compounds. PAMPA, which is a rapid high-throughput screening system, may be useful to predict pesticide absorption because PAMPA permeability can be calculated using log P and other parameters. Electronic and structural properties as well as hydrophobicity are important factors for protein-ligand interaction. To show the importance of physicochemical properties, the classic QSAR and CoMFA of neonicotinoids and prediction of bioavailability of pesticides in terms of membrane permeability in comparison with drugs are described.

Title : Cross-resistance patterns and fitness in fufenozide-resistant diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae).
Year : 2012
Volume : 68
Issue : 2
First Page : 285

Authors : Sun J, Liang P, Gao X.
Abstract : BACKGROUND: Fufenozide is a novel non-steroidal ecdysone agonist with good efficacy against diamondback moth (DBM), Plutella xylostella (Lepidoptera: Plutellidae). At present, it is widely applied for the control of a range of lepidopterous pests in China. This study compared the activities of fufenozide and 12 other insecticides against unselected and fufenozide-selected strains of DBM to examine potential patterns of cross-resistance. The relative fitness of the fufenozide-selected strain was assessed to provide information pertinent to insecticide resistance management. RESULTS: Compared with the susceptible strain (JSS), the fufenozide-resistant strain (JSR) showed high cross-resistance to dibenzoylhydrazines and benzoylphenylureas, low cross-resistance to abamectin and no cross-resistance to organophosphates, carbamates and pyrethroids. JSR had a lower reproductive ability and a relative fitness of 0.5 compared with JSS. CONCLUSION: P. xylostella has the potential to develop resistance to fufenozide, albeit at the expense of fitness. Cross-resistance between the same and other classes of insecticides is of concern, and should be a key consideration when implementing fufenozide-based control strategies for this species.
