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

ABSTRACT   Insect vectors disease is a major problem for chilli crop production in North Sulawesi. The effect is significant in decreasing crop production. The use of plant-derived insecticide is potential and environmentally friendly way in controlling the insect, as a form of integrated pest management. Seeds of Bitung (Barringtonia asiatica) and seeds of soursop (Annona muricata) plants can be used as an organic insectiside to control the several types of insect vectors  in pepper crop. The purpose of this study was to determine effects of the application of extracts of B. asiatica and A. muricata on the growth of insect vector (Aphis gossypii) in pepper and and determine the extracts’s lethal level.  This research was conducted in the Green House of Plant Pests and Diseases Department of the Faculty of Agriculture Unsrat Manado, for 6 months time. The research used a complete randomized design consisting of 6 treatments;  each treatment was consisted of three replications. The results showed that the percentage of dead insects assay (Aphis gossypii) increased as the concentration of the extract used increased. This study found that the concentration of soursop seed extract at 50 g / l and a concentration of 1.75% Bitung seed extract was the best to be used as a botanical insecticide in controlling the insect population vector (Aphis gossypii) in laboratory conditions. It has an effective lethal concentration for 93, 67% and 90.0% of all test insect population. Overall bioactivity increased the effectiveness of soursop Bitung seed extract as botanical insecticides.
