Abstract :
The feeding behavior of Nephotettix cincticeps on different adenine solutions and the estimate relative
number spots of honeydew deposited on the parafilm during feeding test was investigated. The sucrose solution has
a stimulating effect on the feeding of N. cincticeps. During feeding test (60 min) on 2% sucrose solution containing
different amounts of adenine, wave form patterns of probing, salivation and ingestion were different from those
obtained on 2% sucrose solution as a control. At lower concentrations of adenine (0.025, 0.05 and 0.125%), ingestion
are as long and stable as a control with on average period of 53.65 min. At higher concentration of adenine (0.5 and
0.25%) ingestion period is short and disappeared. The average ingestion period was significantly reduced to 13.95
min compared to those at lower concentration of adenine (p
