Abstract

ABSTRACT   The research was conducted in the centre production area of rice plants which on North Minahasa District and laboratory tests conducted in Entomology and Plant Pests Laboratory on Pest and Disease Plant course of Sam Ratulangi University, Manado. This research took one year of research period. The results of testing the power to kill isolates of entomopathogenic fungal isolates obtained the highest is MMTTO which had ability to kill nymphs of Leptocorisa acuta (93.3%). Followed by MMITO isolates (86.7%) and MMSAM (80.0%). The isolates are isolates of the fungus Metarhizium anisopliae. Selection results isolates of B. bassiana in nymphs L. acuta which best is BEMSAM isolates (86.7%) followed BEMTTO isolates (83.3%). Then those isolates will be used for the manufacture of biopesticide. Pathogenicity test results showed that each of entomopathogenic fungi to insects L. acuta after 7 days of infection, average mortality ranged from 83.3 to 93.3% and was significantly different from controls. Isolates Metarhizium sp and Beauveria sp each takes a minimum of 22.4 hours and 29.5 hours to kill 50% of test insects. Keywords : biopesticide, important pests, rice plant

Abstract

ABSTRACT   The study aimed to: (1) know the type of pests and predator that lived during the growth and production of strawberry plants, (2) know the populations of pests associated to the strawberry plants during vegetative and generative development stages until harvest time. The methodology used was Descriptive Method. Sampling the pests associated to strawberry plants was taken by the Method of Deliberate (Purposive Sampling Method). In the vegetative stage, the plants were in 2-10 weeks after planting, and the generative stage of flowering plants until harvest time, or age 11-20 weeks after planting. The results showed that, the pests on strawberry plants growth and development in both vegetative and generative stages, i.e.: seven order were included in nine families, those were: order Orthoptera with Acrididae and Grylotalpidae families; order Coleoptera with Curculionidae and Chrysomelidae families; order Lepidoptera with Pyralidae families; order Diptera with Drosophilidae families; order Homoptera with Aphididea families; order Acari with Tetranychidae families, and order Mollusca. There were six types of pests which destroyed the leaves on  the vegetative phase, i.e.: Acida turita, Locusta sp., Valanga nigricornis, Chrysocus auratus, Tetranychus sp. and Aphis sp., and a kind of destructive root, that was Gryllotalpha sp. There were 11 types of pests in the generative phase, consisted of: a) six pest species destroyed the leaf, i.e.: Acida turita, Locusta sp., Valanga nigricornis, Chrysocus auratus, Tetranychus sp., and Aphis sp.; b) two kinds of fruit pests, those were : Drosphila sp. and Filicaulis bleekeri, c) as well as a type of root pest was Gryllotalpha sp. Keywords : population type and plant pests and predators; strawberry plants

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

ABSTRACT The study aims to determine the effect of the combination of feeding and spawning media against S. nubila egg productivity has been carried out in the Laboratory of Biological Plantation Office, Village Lobbo, North Beo District of Talaud Islands. held for 4 months ie from January to April 2015. Research using completely randomized design (CRD) with treatments that (A) Media dry sand, (B) Media moist sand (C) Media dry soil, (D) Media soil moist, (E) Media mix of soil and sand to dry, (F) Media mixture of soil and sand moist. (G) Each treatment was repeated 4 times. Testing feeding consists of treatment (A) Coconut leaves, (B) Banana leaves, (C) Combination of palm leaves + banana leaves, (D) Reed.  The results showed that the highest egg production was found in Coconut leaves + combination treatment of Banana leaves which reached an average of 50.13 grains followed by treatment Coconut leaves of the grain 36.25, banana leaves 27.11 grain treatment, and treatment reeds 0, 06 grains.

Abstract

ABSTRACT The utilization efforts of entomopathogenic bacteria as an insecticide is still being developed. One of the potential pathogen, which is developed as a source of insecticide is Bacillus spp. The study aims to determine the level of pathogenicity, and get the pathogenity spectrum isolates in the high virulences against the pests of vegetable crops to be used as a biopesticide candidates. Testing the power to kill larvae isolates of Bacillus thuringiensis against Crocidolomia binotalis, Plutella xylostella and Spodoptera litura was performed by the Method of Ohba and Aizawa. The results showed that, of 21 local isolates B. thuringiensis, there were 15 isolates could cause the mortality of > 50% of the larvae of C. binotalis, 20 isolates toward larvae of P. xylostella and 12 isolates toward larvae of S. litura. The isolates, which could potentially be selected based on the pathogenicity, the candidates will then be developed into a biopesticide for pests control of Crocidolomia binotalis, Plutella xylostella and Spodoptera litura on vegetable crops. Keywords: biopesticide, entomopathogenic bacteria, vegetable plants     ABSTRAK Upaya pemanfaatan bakteri entomopatogenik sebagai insektisida masih terus dikembangkan. Salah satu patogen yang berpotensi untuk dikembangkan sebagai sumber insektisida adalah bakteri Bacillus spp. Penelitian bertujuan untuk mengetahui tingkat patogenisitas, spektrum patogensisitas dan mendapatkan isolat yang memiliki virulensi yang tinggi terhadap hama tanaman sayuran untuk dijadikan sebagai kandidat biopestisida. Pengujian daya bunuh isolat Bacillus thuringiensis terhadap larva uji Crocidolomia binotalis, Plutella xylostella dan Spodoptera litura dilakukan dengan Metode Ohba dan Aizawa. Hasil penelitian menunjukkan bahwa dari 21 isolat B. thuringiensis lokal terdapat 15 isolat yang dapat menyebabkan mortalitas > 50 % terhadap larva C. binotalis, 20 isolat terhadap larva P. xylostella dan 12 isolat terhadap larva S. litura. Isolat yang berpotensi selanjutnya akan diseleksi berdasarkan patogenisitasnya kemudian akan dikembangkan menjadi kandidat biopestisida untuk mengendalikan hama Crocidolomia binotalis, Plutella xylostella dan Spodoptera litura pada tanaman sayuran.

Abstract

ABSTRACT The research aimed to find out the attacks and pest populations Scotinophara sp. in rice crops have been carried out in EastBolaang Mongondow from July to October 2014. The study used survey methods at several centers of rice cultivation in East Bolaang Mongondow, then set three districts as a test site where sampling. Sampling using Method Diagonal slices then select ten clump of rice plants in each sub-sample plots. Samples were taken at vegetative stage and generative phase. Things were observed in this study is the percentage of infected plants and pest populations. The results showed that the highest percentage of infected rice plants in the age of the plants 8 weeks after plants are found in Sub Tutuyan amounted to 66.66 percent and the lowest sequentially the District Nuangan and the District Kotabunan namely 39.33 percent and 11.13 percent.The highest Scotinophara sp. population density was found based on the location is district Tutuyan 10,11 tail and the lowest sequentially District Nuangan and the District Kotabunan is 1.82 and 0.96 tail. The density of the population by age of the plant, the highest in the plant age 8 mst 12.75 and the lowest sequentially 6, 4 and 2 mst is4.38, 0.06 and 0 tail.Keywords : attack, population, Scotinophara sp., rice plant
