Comparison of the Number of Population and Attacks Intensity of the Pod Borer (Etiella zinckenella) on Some Varieties of Soybean Crown with Two Cultivation Techniques in Dry Land

Abstract

Dry land is land that is never flooded or inundated most of the time of the year. Soybeans tend to be planted after the rice harvest in the dry season (MK-I). Soybean planting can be done with two cultivation technologies. The need for soybeans continues to increase along with the increase in population. Efforts to increase soybean productivity have obstacles, one of which is pest attack. One of the most common pests that attack soybeans is the pod borer (Etiella zinckenella I); This research was conducted in Stanggor Village, West Praya District, Central Lombok Regency, from September to December 2020. The experiment used a split plot design with two factors and three replications. The research material was the seeds of five soybean varieties, namely Detap-1, Dega-1, Anjasmoro, Biosoy, and Dena-1 which were planted in 2 different lands, the first land was planted using recommended techniques, and the second was planted using traditional techniques; From these statements, it is known that the use of varieties has no effect on the population of pod borer larvae. The intensity of the pod borer attack is influenced by the environment related to the use of cultivation technology on the life of the pod borer pest, and the pod characteristics of each different soybean variety cause different attack preferences on plants. The population of pod borer larvae has a strong relationship with the intensity of the attack, this is presumably because the higher the pest population, the higher the need for food.
