Abstract

This objective of the study is to identify the type of insect pestof 10 soybean varieties. The study used descriptive method with field observation technique, whichthen continued by deviation standard measurement. The data were analysed in tabulation, while the insects pest were identified by using insect manual book. The variable of observation were insect pest type, the forms of damaged, the weight of full and empty pod, the number of trunk, fresh weight, dry weight and plant height. The result shows that there are 8 types of main insect pest of soybean such as Ophiomya phaseoli, Lamprosema indicate, Chryzodeixis calcites, Phaedonia inclusa, Spodoptera litura, Nezara viridula, Riptortus linearis and Phiezodorus hybneri. Ophiomya phaseoli is the most insects found in the soybean plants for about 151, following by Riptortus linearis for about 52 and Phiezodorus hybneri for about 32. Among the 10 soybean varieties, Grobogan, Wilis and Kaba were found to be resistant to the pod borer insects pest while varieties resisted to the stem borerinsect pest were Grobodan, Prafi and Kaba. The highest productivity resulted from Cikuray and Anjasmoron which still attacked by the insects.

Abstract

The study aimed to identify the presence and the population of insect pest to the cultivation of highest productivity soybean. The study designed in randomized block design with the treatments are 6 varieties of soybean such as Anjasmoro (V1), Burangrang (V2), Grobogan (V3), Rajabasa (V4), Detam-1 (V5) and local variety (V6). The data were statistically analyzed and further tested by Duncan (DMRT). The result showed that Ophiomyia phaseoli, Lamprosema indicata, Nezara virudula, Riptortus lineavis, and Etiella zinckenella were the main insects pest found in the 6 varieties tested. Analysis of variance showed that the majority of pest insect populations did not differ between the varieties tested, except for observations at 4 and 5 weeks after planting. The population of beetles mostly found at 11 weeks after planting. The population of insect pest at Anjasmoro variety relatively low compared to other varieties. All tested varieties can be used to increase the productivity of soybean, especially Anjasmoro variety, but the presence of Lamprosema indicata need to be aware at 4 to 5 weeks after planting especially for Detam-1 and Rajabasa varieties.
