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. Keywords: Diversity, natural enemies, insect pest

Abstract

ABSTRACKRice is an annual plant, belonging to the grasses of the Oryza genus, family of Graminae (Poaceae), with Oryza sativa L. being one of the species. Rice is the main commodity for the Indonesian people. In Indonesia, rice is an important food crop because more than half the population are dependent on rice produced by rice plants. This study aims to determine the potential of some types of plants that serve as attractants for the channeled applesnail. This research was conducted in farmers' fields in the village of Tonsewer from March to October 2013. This study uses a completely randomized design with four treatments and three replications in the research sites. Materials and tools used in this study are the leaves of banana plants, papaya, taro, and tagalolo, buckets, rough scales, plastic rope, knife, tape measure, camera and stationery. The results showed the highest population on taro leaves (106.73 individuals), followed by papaya leaves (59.53 individuals), tagalolo leaves (41.47 individuals), and the lowest population in banana leaves (38.73 individuals).Keywords: Rice, Channeled Applesnail (Pomacea canaliculata), Attractant plants

ABSTRACTMargareta M. Kawulusan. Population Lamprosema indicata (Lepidoptera: Pyralidae) to Plant in Red Beans at District Tompaso and Kawangkoan Regency Minahasa. Guidence Prof. Dr. Ir. Odi R. Pinontoan, MS as chairman, Dr. Ir. Mareyke Moningka, MS and Dr. Ir. Dantje Tarore, MS as member.This study aims to determine the symptoms and attacks on the population of L. indicata red beans crops in the district Tompaso and Kawangkoan, Minahasa regency. The study uses survey and sampling methods are purposive sampling at a predetermined location. Area is used as an observation area set at 300 m2 which is divided into five sub-plot of the observations in the form of diagonal slices. Observations on the larval population sub-plot planting beans defined five beds and beds of each plant sample was observed ten systematically determined. Observations were carried out five times at intervals of seven days in the time period of 2-3 weeks old plants. Things were observed in this study is a symptom of pest attack L. indicata larvae collected and the number of observation each time.Pests attack L. indicata encountered red bean crop farmers in the district Tompaso and Kawangkoan. Population larvae L. indicata in District Kawangkoan peak in the third observation that 6,60 in the village were in the village Kanonang Tondegesan, observation of a peak in the fourth with an average population of the same, namely 6.60. While in the District Tompaso, peak larval populations of L. indicata third at 7.00 on observations of individuals in the village Tonsewer I, a peak in the second observation with the population average of 6,80.Key words : Lamprosema indicatai, Kacang Merah, Minahasa

Abstract

ABSTRACKRice is the main commodity for the Indonesian people, because rice is an important food crop in which half of Indonesia's population depend on rice, even half of the world's population makes rice as the staple food. This study aims to determine the population of S. exempta pests in rice paddy fields in the village of Two Molompar Northern District of East Tombatu Southeast Minahasa regency. The research was conducted at the location of paddy rice cultivation In October-December 2013 This study used a survey method with sampling deliberately by choosing plant pests. Materials and tools used in this research is cropping Rice, meter, Aqua Glass, Peg, paper labels, plastic rope, Scissors, Box collection, Microscope, Petridis, Calculators, digital camera for documentation and stationery. The observation of the larval population of S. exempta in rice paddy fields in the village molompar two north, found that populations of this pest on plant age 60 HST is 3.3 tails. Then the next observation at the age of 67 plants as much as 2.1 HST observations of the tails and the third at the age of 75 plants of S. exempta HST population is 2 larvae.
