Abstract

ABSTRACTThis study aims to determine the insect pest population C. formicarius at different altitude. The experiment was conducted in several sweet potato plants centers in the Sinisir Village District of Modoinding South Minahasa Regency, Woloan Village 1 District of Central Tomohon, City of Tomohon, and Sumarayar Village District of Langowan Minahasa regency. The study was conducted from June to December 2012.

The research was carried out during 3 (three) months i.e. started from August until November 2012, which is located in the Tomohon City and District of Modoinding. Working procedures of the study include: (1) a collection of the death P. xylostella larvae by taking samples along with cabbage leaves, (2) identification of fungi associated with dead P. larvae xylostella through macroscopic and microscopic observations and isolation on PDA + AB medium by direct plating and dilution. The results showed that there are five species of fungi of the death P. xylostella larvae, namely Hirsutella sp. , Metarhizium sp, Penicillium sp., Fusarium sp., and Aspergillus sp. The species of fungi Hirsutella sp. and Metarhizium sp. including entomopathogenic fungi, while Penicillium sp., Fusarium sp., and Aspergillus sp. may be opportunistic or saprophyte.Keyword: Dead P.xylostella larvae, entomopathogenic fungi, opportunistic fungi

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.
