Abstract

Sugar cane (Saccharum officinarum Linn.) is a tropical plant that is very important because it can be used as one of the raw materials for making sugar. The development of sugar production in the last ten years has decreased by around 1.8% per year, this is due to several factors, one of which is due to the attack of sugarcane insect pests. Therefore, research was conducted to find out the diversity of important insect pests in sugarcane plants in the center of sugarcane development in the Dompu  District. This research was conducted at the Pekat Sub District of Dompu District, West Nusa Tenggara. The method used is a descriptive method with data collection techniques directly and indirectly in the field at a number of observation points. Based on the observations there were 5 species of insect pests in the research area such as Valanga nigricornis, Locusta migratoria, Ceratovacuna lanigera, Scirchopaga nivella F., and Lepidiota stigma. Insect pests with the highest population and dominance are Ceratovacuna lanigera with an average population of 70 insect/plant and a domination index is  0 .199808. Locusta migratoria has a level of damage with criteria for moderate attack intensity, it is found in sugarcane plants aged 3 months. The results of this study indicate that Scirchopaga nivella F. and Lepidiota stigma F. insect pests have the potential as important pest insects on sugarcane crops

Abstract

This study aims to determine the diversity, abundance, and dominance of predators in potato plants treated by synthetic non-chemical insecticides on the medium plain of Lombok Island. The research used Randomized Block Design with ten different synthetic non-chemical insecticide treatments such as Metarhizium anisopliae, Beauveria bassiana, and Bacillus thuringiensis, Neem extract, tobacco stem extract, soursop leaf extract, babandotan leaf extract, chemical insecticide treatment, and one treatment without insecticide as a control. The insecticide was applied after 37 days of planting eight times at 7-day intervals. The type and population of predators were observed five days after the treatments. The diversity index (H'), abundance (K), and dominance (D) of the predators are then identified and determined. Data were analyzed by using a Diversity analysis followed by a 5% beda nyata jujur (BNJ). The yield shows six predatory families: Formicidae, Coccinellidae, Mantidae, Lycosidae, Oxyopidae, and Aranedae. H' and K values are generally classified as the low category, and no species dominates in each treatment (D <0.5). The value of H' and K in B. thuringiensis treatment was higher than other treatments. The highest D value was obtained from chemical insecticide treatment. Formicidae is the family with the highest population compared to other families
