Abstract

ABSTRACTThe experiment was conducted using a survey method at 4 locations/district in the Southeast Minahasa Regency is Belang,Tombatu, North Tombatu, and East Tombatu. Each location/districts determined three paddy fields (repeats) as a place of observation and sampling. The study lasted for 10 months ie from January to October 2015. Sampling is done diagonally to the respective fields. So one rice field consists of 5 sub-plot as a point of sampling Samples are larvae present in the leaf roll. Implementation of the sampling carried out on rice plants vegetative phase once a week for 6 weeks. The results showed that the average population of C. medinalis (per-10 clumps) on paddy rice cultivation in Southeast Minahasa Regency highest found in the location of the North Tombatu 10.99, then Eastern Tombatu 10.44, Belang 10.43 and lows in the Tombatu 0.94. Observations of percentage of pests C. medinalis highest in Southeast Minahasa Regency found in the sample locations in the North Tombatu which reached 33.95%, Belang 32.51%, Eastern Tombatu 31.86%, and the lowest in the Tombatu 4.08%.

Results showed that the papaya mealy bug,Paracoccus marginatus (Hemiptera: Pseudococcidae) has spread and establised in North Sulawesi butits level of infestation has been from low to medium depending on the location. The main naturalenemies found on the papaya mealy bug were Coccinelidae (Coleoptera), Hermetia illucens (Diptera:Stratiomyidae) and Acerophagus papaya (Hymenoptera: Encyrtidae). The Cycad scale, Aulacaspisyasumatsui Takagi (Hemiptera: Diaspididae) and yellow beetle, Lilioceris sp. (Coleoptera:Chrysomelidae) were first recorded on pakis haji in North Sulawesi and causing damage to pakis haji inthis region. The predator found on cycad scale was a beetle, of the famili Cybocephalidae genusCybocephalus.Keywords: Paracoccus marginatus, Aulacaspis yasumatsui, Lilioceris sp, papaya and pakis haji

Abstract

ABSTRACT Study aims (a) to determine the effectiveness of Trichoderma sp., combination PGPR and Trichoderma sp., and PGPR to the development of diseases that attack strawberry plants, (b) to study the effect of application of Trichoderma sp., combination PGPR and Trichoderma sp. and PGPR for strawberry production.  The experiment was conducted in the village Rurukan (Mahawu), subdistrict Tomohon Timur.  Study lasted from March to August 2013.  Experiments using a randomized block design with 4 treatments, as follows: Treatment A = Trichoderma sp., Treatment B = PGPR, Treatment C = combination of Trichoderma sp. and PGPR, and Treatment D = Control.  The experiment was repeated 4 times.  Data were analyzed using Minitab software ver. 14.  Things that observed the symptoms of disease, number of shoots, roots and heavy weight of strawberries.  The results showed that strawberry plants are not attacked by various diseases. Fungus Verticillium sp. encountered attack strawberry plants with very low intensity.  The average number of shoots ever encountered on the 6.25 shoots PGPR treatment and lowest in the control treatment, ie 2.20 shoots .  The average weight of the heaviest roots found in the PGPR treatment and 68.75 grams of the lowest in the control treatment, which is 13.50 grams.  The average weight of the fruit of the highest found in the 731.25 grams of PGPR treatment and lowest in the control treatment fruit weighing 417.50 grams.

ABSTRACTThe research aims to find out about the type of insect pests population in potato plants Solamun tuberosum L. in Modoinding, South Minahasa. The research was conducted on the potato plants in Modoinding, South Minahasa. The research was carried out by using the survey method on potato in Modoinding's villages, South Minahasa, such as Palelon Village, Makaaroyen Village, and Lineleyan Village. The sampling was carried out with a diagonal incision method that established of five sub-plot that is on the corner and the middle of the sampling sites. The sampling was done by using insect nets that swung above the potato crop for ten times the double swing. The netted insects are immediately put into the "killing bottle" then collected in 70% alcohol to be identified. Identifying the type of insect pests is done by using the facilities of the Entomology and Pest Plant Laboratory, Faculty of Agriculture, UNSRAT. The results of the research of the associated pests on potato was found about eight kinds of insect pests, such as Empoasca sp. 109.03, Drosophila sp. 37.03, Nesidiocoris sp. 34.11, Lirionyza sp. 10.72, Lygus sp. 4.47, Phthorimaea sp. 2.97, Antractomorpha sp. 1.61, and Epilachna sp. 0.69.
