In a recent study, resistance to the neonicotinoid insecticide, imidacloprid, in the brown plant hopper, Nilaparvata lugens, was found to be due to a point mutation at a conserved position in two nAChR subunits. As a result, it reduced the receptor binding of imidacloprid (Liu et al., 2005).

Asperparaline A (123) showed remarkable insecticidal activity against third instar larvae of Nilaparvata lugens, third instar larvae of Nephotettix cincticeps, and the adults of Musca domestica. 

Diazinon applied to paddy water at 2 kilogram/ha active ingredient every 20 days has controlled for several years common insect pest of rice at the International Rice Research Institute. After its continuous use for three and a half years, its efficiency for controlling rice brown planthoppers Nilaparvata lugens Stal) declined. Preliminary studies indicated that biodegradation might be involved. Detailed studies were undertaken and reported elsewhere (17). However, brief descriptions of the procedures used will be provided for better clarity to the reader. 

The preliminary bioassays showed that most of them exhibited moderate insecticidal activity against pea aphids. Compoimd 4a acts on a wide range ofinsect pests via further research, including important species, such as Nilaparvata lugens (LCjqI...
