Abstract

ABSTRACT The objective of this research was to know the diversity of natural enemies (parasitoid and predator) on wet rice-field, so that could be bread to control pest insects with a tactic that is easy, cheap, efficiently and environment safe. Catching a natural enemies species was conducted in district of Tumpaan and Tenga (which was the centre of rice production in South Minahasa Regency) by sweeping (using insects trap) and direct observation in the field. The specimen insect was brought to the laboratory for identified. Diversity was measured using Shannon-wavers, and then continued to decide the species abundance average level. The natural enemies species which were found consist of five ordos of predator (Araneida, Hemiptera, Odonata, Coleoptera, and Orthoptera); 10 families; and 16 species; two ordos, 10 families and 13 species of parasitoid. The result of variance analysis showed that the abundance average level (J) of 29 species (predators and parasitoid) which were found almost the same and this value refer to value that almost the same on the diversity in species group (H) during observation either the old crop stadia or the location of rice plant.

Abstract

Eco-enzyme (EE) liquids produced by fermenting fruit waste may provide low-cost, locally available odor sources for fruit-fly monitoring. This study evaluated the effectiveness of EE baits prepared from nutmeg, banana, and pineapple wastes, as well as a mixed formulation, for trapping Bactrocera spp. in chili (Capsicum frutescens L.) fields in Kakaskasen I Village, Tomohon City, Indonesia. The experiment used a randomized complete block design with four EE treatments and five replicates. Traps were installed in fruiting-stage chili plots at approximately 1.5 m above ground level with ~5 m spacing and were observed over four sampling rounds at 6-day intervals. Captured adult fruit flies were counted and identified morphologically, and treatment effects were analyzed using analysis of variance followed by an LSD (BNT) test at the 5% significance level. Two species were recorded, Bactrocera dorsalis and B. cucurbitae. Mean trap catches (adults per trap) were highest for pineapple EE (6.3), followed by mixed EE (3.1), nutmeg EE (1.7), and banana EE (1.3). Pineapple EE differed significantly from the other treatments (LSD5% = 3.7), whereas the remaining treatments did not differ significantly. Captures were reported to be predominantly female, and non-target insects were also collected, indicating limited selectivity. Overall, pineapple fruit-waste EE showed the strongest field performance and warrants further development as a practical bait for Bactrocera spp. monitoring in chili agroecosystems.
