Feeding Behaviour of Pymetrozine-resistant and Susceptible Strains of Brown Planthopper Nilaparvata lugens (Stal)
Feeding behaviour of pymetrozine-resistant (Pym-R) and pymetrozine-susceptible (Pym-S) brown planthopper Nilaparvata lugens Stal strains were investigated using standard honeydew and probing tests. Under both the treated and untreated conditions the food consumption of Pym-R strain was higher (4.0 and 12.4 cm2 area of honeydew respectively) compared to Pym-S strain (2.7 and 7.1 cm2, respectively). Probing activity of both the Pym-R and Pym-S strains increased on rice seedlings treated with pymetrozine (35 and 26 probing marks, respectively) compared to untreated seedlings (12 and 13 probing marks, respectively) and on treated seedlings the Pym-R insects probed more (35 probing marks) as compared to Pym-S insects (26 probing marks). Plausible reasons for differences in the feeding behaviour of pymetrozine resistant and susceptible populations is discussed.
