ABSTRACT: Biological
parameters of insect pests is very important in testing the resistance of rice
plants against brown plant hopper. This research aims to study the amount and
duration of stage egg, nymph, imago, and the life cycle of brown plant hopper
on four varieties of rice. The methods used in research was Complete Random
Design with four treatments (variety of
IR 64, Batang Piaman, Cisokan, and IR 42) and eight replications. Research data
were analyzed using variance analysis and continued with List Significant
Different (LSD) at 5% level. The results of research showed that the number and
duration of stage egg, nymph, imago, and cycle time of brown plant hopper in
four rice varieties were different. Number of egg, nymph, and imago were lowest
in 64 IR varieties, while the highest was IR 42 variety. Stage of eggs and
nymphs were the shortest in IR 42 varieties, while the longest were IR variety
64. Imago stage was the shortest in IR 64 variety, while longest was the
variety IR 42. The life cycle of brown plant hopper were shortest in IR 42
varieties, while longest was the variety IR 64. The results of this study can
be concluded that the IR 64 varieties more resistant than the varieties IR 42,
Cisokan, and Batang Piaman based on stage of egg, nymph, and imago.
