ISOLATION AND IDENTIFICATION OF ENTOMOPATHOGENIC ON CROSIDOLOMIA BINOTALIS [ZELLER] (LEPIDOPTERA : PHYRALIDAE) USING 16S rRNA GENE: ISOLATION AND IDENTIFICATION OF ENTOMOPATHOGENIC ON CROSIDOLOMIA BINOTALIS [ZELLER] (LEPIDOPTERA : PHYRALIDAE) USING 16S rRNA GENE Carolin Manuahe

Abstract

The aims of this reserach were to isolating and to identifying bacteria entomopathogenic on caterpillar pests in cabbage. The study was conducted in three phases. The first stage isolation of bacteria from cabbage caterpillar pests, the second stage of microscopic characterization of bacterial isolates and the third phase molecular identification of bacteria isolates using 16S RNA gene. The results were obtained five bacterial isolates of caterpillar pests in cabbage which 4 isolates shaped cocus, three isolates of gram positive and gram negative two isolates. All of isolates were able to degrade D-glucose. Isolates were translucent white color, white yellowish and brownish white. Generally isolates are not motile dan growth in the media to the surface. Results of DNA extraction and amplification of 16S RNA gene, showing the purity and concentration of DNA is good, confirmed by electrophoresis, amplicons formed band at 1500 bp according to the characteristics of the 16 S RNA gene

Abstract

Aedes mosquitoes have the behavior of sucking blood repeatedly (multiple bites) in one gonotrophic cycle, these mosquitoes are also very effective at transmitting the virus to humans (WHO 2004). Kawada et al. (2007) reported that the foraging activity of A. albopictus was less than 0.1 times compared to A. aegypti under laboratory conditions, this result is consistent with the tendency to bite both species in nature. The target-attack frequency (foraging activity) in A. aegypti female mosquitoes in unfed conditions is 30 times greater than that of A. albopictus mosquitoes in several laboratory treatments (Kawada, et al. 2007). Aedes sp is a deadly infectious vector between another dengue hemorrhagic fever (DHF) and chikungunya. Pineleng is a marginal/suburban area of Station 1. Recent studies have reported changes in habitat patterns of Aedes sp, especially Aedes albopictus and Aedes aegypti . The aim of this study is to characterize the population density of the Aagoan sp. Imago based on the time distribution and altitude of the sea surface. The population density characteristics of the Aedes spagoed imago captured inside and outside the room based on the time distribution in North Sulawesi. The stages of the study consisted of larvae surveying, larval extraction and analysis, and imago extraction and analysis. The results showed that the high population of Ae aegypti was at 8:00 a.m. to 10:00 p.m. in the morning and 14:00 to 16:00 p.m. in the afternoon before the afternoon. in the morning before noon and at 14:00 to 18:00 in the afternoon before evening.
