Abstract

ABSTRACT   The purpose of research is to know the preferences of Sitophilus oryzae in rice, corn, peanut, soybeans, and copra. Experiments using observational and substitutional methods with research objeck is the interest of S. oryzae in some kind of postharvest material. Parameters measured were population density of pests, feeding damage caused by pests, and the relationship between population densty of pests and postharvest material damage caused by pests feed of S. oryzae. The results showed that S. oryzae choose food according to its main host. Population density are highest at 20.8 tail in rice, corn followed by14.0 tail, 8.2 tail in peanuts, 7,0 tail in soybeans and the lowest in copra is 4.0 tail. The results of feeding test showed that S. oryzae can not live in peanut, soybeans, and copra. Damage to feed straight to the population density S.oryzae. The amount of damage depends on the amount of feed that is higher pest populations, the greater damage in flicted on feed. Key words: preferences, Sitophylusoryzae, rice, corn, peanut, peanut soya, copra

Abstract

ABSTRACT The aim of this research is to know the attack and damage of clove stem borer Hexamitodera semivelutina at some elevation in Rerer village of Kombi sub-district of Minahasa Regencyfor 2 months (February - April 2017). The research was conducted by survey  on farmers’ clove plantation area. The research was using a stratified random sampling method with observing the incidence and severity of H. semivelutina pest of clove plant. Treadment using 3 stratum height of place from sea level  that is 0 - <300 meters from sea level (mfsl), 300 - <600 (mfsl), and >600 (mfsl). The result of this research are the symptom of attack and damage of clove plant caused by H. Semivelutina pest as follows : incidence rate and severity according to altitude of place 0 - <300 mfsl are 24.67% and 12.55%, while at height 300 - <600 mfsl are 42.34% and 22.88 %, and at altitude> 600 mfsl are 61.67% and 33.66%.Keywords : incidence of pest, severity of pest, Hexamitodera semivelutina

ABSTRACT Rice Black Bug (Scotinophara coartata F) is one of the most important pests that attack rice crops and has caused major losses. The purpose of this study is to determine the Rice Black Bug preferences in some varieties of rice crops. This research was conducted in Modomang Village, East Dumoga Subdistrict of Bolaang Mongondow Regency from November 2016 - February 2017. This research used Completely Randomized Design (CRD) with 5 treatments, namely several varieties of rice field cultivation (Ciherang, Cigeulis, Membramo, Pertiwi and Serayu).Based on the results of this study showed that the population of S. coartata pest with the largest average in Serayu varieties of 6 tails, followed by Membramo 3.75 tail, 3.5 Pertiwi, 3.5 Cigeulis and the lowest Ciherang with an average of 3.25 tailKeywords: preferences, rice black bug pest, varieties plants rice

Abstract

ABSTRACT   The research was conducted in the village of Mapanget, Mapanget West District of Manado City for five months from February to June 2015. This study used a factorial design in a completely randomized design (CRD) with two factors was garlic ekstrak and tobacco and repeated for three times. The result showed that each kind of  extracts garlic, tobacco and the combination of the two (synergistic) have the potential as the bioinsecticides against leaf aphids (Myzus persicae Sulz.). For a single factor, the average percentage of the highest mortality of each extracts was garlic extract on concentration?s treatment 60% with 72,33% of death rate, tobacco extract on concentration?s treatment 60% with 76,33% of death rate of leaf aphids. As for the combination between garlic extract and tobacco extract, from 25 combinations that have been applied, there are 13 concentrations which effective to known as a bioinsecticide that have capability to caused mortality above 50% with the highest mortality percentage on 60%:60%  treatment which had 91,7% average of death rate. Keywords : effectiveness, bioinsecticides, Myzus persicae
