Abstract

Maize (Zea mays L.) is the main food crop in Indonesia after rice, but is vulnerable to attack by plant pests (OPT), including Spodoptera frugiperda, an invasive insect that attacks corn plants. This research aims to observe the population, level of attack and characteristics of the pest of S. frugiperda in West Lombok Regency. Based on observations, the eggs of this pest are brownish white, round in shape, and have an average size of 0.33 mm × 0.47 mm. The male pupa is reddish brown with dimensions of 14.25 mm × 4.32 mm, while the female pupa is larger, namely 17.53 mm × 5.13 mm. Larvae are found in various instars (2-6) with sizes from 1.53 mm to 35.16 mm, and colors varying from light green to dark brown. Male imagos are smaller than females, with a length of 12.45 mm and a wingspan of 27.73 mm, while female imagos have a size of 14.38 mm and a wingspan of 31.47 mm. The highest population was found at location 3 with 123 larvae, while the lowest population was at location 13 with 1 larva. The highest attack rate occurred at location 7 (50%) and the lowest at location 11 (5%). The observation method includes assessing the level of damage based on the attack intensity score (0–4). This research proposes further studies to understand the distribution and control mechanisms of S. frugiperda in order to minimize its impact on corn cultivation, especially in Nusa Tenggara Barat, Indonesia.

Abstract

This study aims to determine the effect of applying various concentrations of botanical pesticides derived from Virginia tobacco stem waste on the diversity of spiders in potato plants. The research was conducted in Sembalun Bumbung Village, Sembalun District, East Lombok Regency, West Nusa Tenggara Province. The method employed was an experimental method with field trials, using a Randomized Block Design (RBD) with six treatments: P0 (control), P1 (abamectin), P2 (Virginia tobacco stem extract 2 ml/L), P3 (Virginia tobacco stem extract 4 ml/L), P4 (Virginia tobacco stem extract 6 ml/L), and P5 (Virginia tobacco stem extract 8 ml/L). The experiment was conducted in three blocks, resulting in 18 experimental units. The results showed that the application of various concentrations of botanical pesticides from Virginia tobacco stem waste did not significantly affect spider diversity in potato plants. However, the P3 treatment (Virginia tobacco stem extract 4 ml/L) exhibited a higher tendency in population, diversity index, abundance index, and dominance index compared to other treatments.
