Abstract

Occurrence and morphometrics of bamboo sap sucker, Udonga montana was studied from different locations of Sagar taluka, Shivamogga district, Karnataka. The variation in size and the horns on either side of the pronotum were evaluated. The survey was done at fortnightly intervals starting from July-September 2014 in three clusters of Ananadapura, Kasaba and Awinahalli. Of the 200 bugs observed, 80.75% adults had no spines or horns, and 7.33% were with horns on both sides of pronotum. Also, there were few adults with horn only either on left or right side of their pronotum (5.92 and 6.00%, respectively). Variation in terms of body length, width and antennal length of horned and hornless were insignificant. Critical observations indicated that bugs were not feeding on any horticulture or agriculture crops.
