Abstract

An important pest that attacks long bean plants is the green ladybug (Nezara viridula L.). Green ladybug attacks cause the young pods to become empty and deflated, because the seeds do not form and the pods fall. Several field tests showed that yield loss by one adult N. Viridula per two plants caused pod damage by 49%. The aim of the study was to determine the color and height of the traps that were effective in trapping the green ladybug (Nezara viridula L.). The study was conducted in Taeno hamlet, Rumah Tiga Village, Teluk Ambon District from April to June 2022. The study used a Randomized Block Design (RAK) with 2 treatments. The first treatment was a trap color consisting of 3 levels, namely red, yellow and green. The second treatment was the height of the trap which consisted of 3 levels, namely the height of the trap 1 m, 1.5 m, and 2 m above ground level. The results obtained information that the interaction between the red trap color and the 1.5 m trap height had a significant effect on the number of green ladybug populations trapped in the 1st to 4th observations. -3 is found in the use of yellow traps, while in the 4th observation the interaction between green traps with a trap height of 1.5 m.

Abstract

Spodoptera exigua Hubner is one of the major pests of shallot plants causing significant yield losses. This study aimed to evaluate the effectiveness of Exi pheromone traps against S. exigua populations and damage intensity on shallot (Allium cepa var. ascalonicum L.) in Taeno Atas Hamlet, Teluk Ambon District, Central Maluku. The study employed a Completely Randomized Design consisting of two treatments, namely pheromone traps (PF) and yellow traps + pheromone (PKF), with four replications each. Observations were conducted for eight weeks on the number of trapped imagoes and plant damage intensity. Data were analyzed using analysis of variance followed by the Honestly Significant Difference (HSD) test at a 5% significance level. The results showed that pheromone traps were significantly more effective in capturing S. exigua imagoes than yellow traps + pheromone. The highest average imago catch was recorded in PF treatment with 15.7 individuals, while PKF captured 9 individuals. The lowest damage intensity was observed in PF treatment (11.31%), whereas the highest occurred in the control treatment (15.62%). Trap effectiveness was influenced by pheromone volatility, which attracted male imagoes through chemical communication during mating behavior. The use of Exi pheromone has the potential to become an environmentally friendly technology in Integrated Pest Management (IPM) systems to suppress S. exigua populations on shallot crops.
