Abstract

ABSTRACT This study aims to obtain entomopatogenik bacteria (Bacillus cereus) as a potential biological control of pests Spodoptera litura and determine the morphological characteristics and the potential power to kill isolate B. cereus. Explored endogenous bacteria from 99 soil samples from Minahasa regency, South Minahasa and Tomohon. Bacteria were isolated by selectively using methods Ohba and Aizawa  identified by colony and cell morphology. The results showed that of the 99 soil samples obtained 141 isolates were identified as Bacillus cereus. Screening 141 isolates of the 80 isolates contained S.litura larvae that can cause deadly diseases and test larvae  >50% after 96 hours with a dose of inoculum  1.5 x 107 spores / ml. Isolates that could potentially then be selected based on the pathogenicity then be developed into a biopesticide for pest control S. litura on cauliflower and broccoli plants. Keywords: Entomoopatogenic bacteria, Spodoptera litura, cabbage plants

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.

ABSTRACT  Plants Gedi is one type of horticulture type of vegetable can also be used as medicinal plants (Papodi et al, 2013) and is the type of vegetables typical of North Sulawesi, because it is a vegetable that is commonly used by the people of North Sulawesi as an ingredient for typical food from this area that Manado porridge, the field survey results show that the existence of some types of insects that attack plants Gedi. This causes a decrease in the quantity and quality of crops Gedi. This study aims to menngetahui types of insects on plants Gedi in the Village and Village Kalasey.Penelitian Lolah was conducted in two villages, in the village Lolah and Kalasey for three months from November 2016 to January 2017. This study used purposive sampling method in plants gedi in both villages. Each village was taken 4 locations. Sampling was conducted using an insect net and using tanagn. There are 4 orders were found, namely: the Order Hemiptera comprising two families (Family Pentatomidae and Family Plataspididae), Order Coleoptera consist of 5 Family (Family Chrysomelidae, Family Coccinelidae, Family Curculionidae, Family Buprastidae and Family Carabidae), Order Orthoptera (Family Acrididae) Order Lepidoptera (Pyralidae).

ABSTRACTBanana (Musa paradisiaca L) is a commodity that is quite attractive to be developed andincreased its production, if it is viewed from the aspect of International trade. Indonesia is acountry is ranked sixth out of the to ten Banana producers in the world and accounts for around30% of domestic fruit production. Banana plants can grow well in low and high areas with analtitude of not more than 1600m above sea level. Many factors can inhibit plant growth,including disease attacks. Some Banana cuktivars that have been released are infected with theBunchy Top Virus. This study aims to determine the Incidence of Bunchy Top Virus attack onBanana plants in Bitung City, Aer Tembaga District, which is located in three villages, namely inKasawari Village, Makawidey Village, and Tandurusa Village. This research was carried out forthree from October to December 2018. This research was conducted by survey method or directobservation at the research location. The results of research on the Incidence of BananaBunchyTop Virus in Bitung city, Aer Tembaga sub-district in three villages. The highest averageIncidence of dwarf disease was in Makawidey villages 11,3%, followed by Tandurusa villages at10,6% then the ;owest Incidence occurred in Kasawari villages 3,45%.
