Abstract

Arthropods can be loss and solution sources for Platycyamus regnellii saplings. This study aims to evaluate the herbivorous insects and their natural enemies on 48 P. regnellii saplings. They were classified according to their ability to damage or reduce the source of damage on these saplings using the percentage of the Importance Index-Production Unknown (% I.I.-PU). The loss sources Aleyrodidae, Tettigoniidae, Tropidacris collaris, and Phenacoccus sp., showed the highest % I.I.-PU on leaves of P. regnellii saplings. Araneidae was the only solution source, showing the highest % I.I.-PU on leaves of P. regnellii saplings.
