Abstract

Pod sucking bugs are the important pest that can causing yield loss soybean on quality and quantity. The objectives of the research were to determine effectiveness botanical insecticides and using varieties to pod sucking bugs along with presentation yield soybean. Species pod sucking bugs that identify to soybean plants at location research it is Riptortus linearis and Nezara viridula. There are three kinds of N. viridula that identify that is N. viridula var. torguata, N. viridula var. aurantiaca, and N. viridula var. smaragdula. The botanical insecticide that used in research be possessed of ability have variation in controlling pod sucking soybean. Extract leaf Tephrosia vogelii and Azadirachta indica causing intensity damage that lower more as well as increase component yield than with extract leaf and flower Lantana camara. The are difference resistance varieties Kipas Merah and Anjasmoro to damage pod sucking bugs that showed by difference intensity damage, number of trichomes, and yield. Level damage pod effect injury sucking to varieties Kipas Merah and Anjasmoro diverse follow characteristics morphological at pods varieties soybean as number of trichomes, wide surface pod, and number pod per nodes. Number of trichomes at varieties Kipas Merah that is 41.6 trichomes/4 mm2 many more than with varieties Anjasmoro that is 29.1 trichomes/4 mm2 .
