ABSTRACTAlva Garry Rorong 080318010. Type and Insect Populations in Plant seeds Jabon Red Anthocephalus macrophyllus. Under the guidance of PINARIA, BAN, as chairman, DEEN, MF and Chain, CS as a member.The experiment was conducted at the Forestry Greenhouse Science Program, Faculty of Agriculture, University of Sam Ratulangi, then continued in the laboratory of Entomology and Plant Pests UNSRAT Faculty of Agriculture. This study was carried out for 4 months ie June to September 2012 This study aims to determine the type and insect populations found in plant seeds Jabon red.Total seed used for this study were 80 seedlings. Planting in polybags done manually which makes the planting hole as deep as 7-10 cm by hand, and then the seeds are planted in the hole until the roots are embedded. This study uses a red seed Jabon 3 months old in the nursery area of the Faculty of Agriculture, University of Sam Ratulangi. One month after the first was in the nursery area, remove the seeds and place it in an open area. Seeds are4placed one by one on a regular basis with a distance of 20 x 30 cm. Insects were collected in a bottle found 70% alcohol for identification. Sampling was conducted in the morning (06:00 to 08:00 hours) and afternoon (Jam 4:00 p.m. to 6:00 p.m.) using insect nets mainly on the type of insect that is active and catching fly directly use an aspirator to the non-flying insects. Insects were collected in bottles containing 70% alcohol to be identified in the laboratory. Observations were made on all samples of plants and sampling was performed five times with intervals of once a week.Insects were found to be separated according to its kind, and then identified. Samples of insects were identified to family level using a library Anonymous, 2011b; Myers., Et al, 2014; Lovett G, 2014.The results showed that insects found in red Jabon plant nursery consists of 4 orders, namely: (1) the Order Hymenoptera (Family Cynipidae, Sphecidae, Formicidae); (2) Order Coleptera (Family Scarabaidae); (3) Order Odonata (Libellulidae Family), and (4) Order Homoptera (Family Aphididae) and Family Pseudococcidae. Average of the highest insect population in a row of 173 Family Aphididae tail, Family Pseudococcidae 88.8 tail, tail 43 Family Formicidae, Family Scarabaeidae 4.4 tails, Family Sphecidae 1 tail, tail 0.6 Family Cynipidae and Family Libellulidae 0, 4 tails.

Abstract

ABSTRACKCabbage (Brassica oleracea var. Capitata L. f. alba DC) is a vegetable that contains vitamins, minerals, proteins, carbohydrates and grese for the formation of human body and increase energy for the activity of human muscles. North Sulawesi is a region that has a large planting vegetables in the east of Indonesia. Cabbage crop harvested area of approximately 1,614 ha, with an average production of 17.25 tonnes per ha. The low production of cabbage in North Sulawesi caused by farming system which is still conventional and the presence of pests especially Plutella xylostella and Crocidolomia binotalis. The study aims to determine the percentage of the population and parasitization of the parasitoid Diadegma semiclausum in District Modoinding. The experiment was conducted in the South Minahasa Modoinding. Implementation of the study lasted for six months, start from July to December 2013, the research using survey method conducted on cabbage and other Brassicaceae plant at Modoinding District of South Minahasa Regency. Criteria for the location of the sample is the presence or type of cabbage and other Brassicaceae. Materials and tools used in this research are larvae and pupae of Plutella xylostella, Brassicaceae plants, sample bottles, bottle collection of 70% alcohol, tweezers, scissors, cutter, aqua glass, asahi cloth, rubber bands, "hand counter" and "loupe" , as well a stationery. The observation of parasitoid parasitization highest percentage found in the village of Lineleyan which reached 25.23%, then the Kakenturan Village respectively 17.40%, 1.83% Pelelon, Sinisir 1.05%, 0.93% and Mokobang Wulurmaatus 0.59%. Results sweeping using insect nets on cabbage and other Brasicaceae found that the highest population in the village of D. semiclausum Lineleyan (25, 42 individuals), and then successively Kakenturan Village (19.08 individuals), Palelon village (4.75 individuals), Sinisir village (4.50 individuals), Wulurmaatus village (4.08 individuals), and the Mokobang village (2.66 individuals).Keywords: Plant cabbage,Plutella xylostella and Diadegma semiclausum

ABSTRACTThe study aims to determine the type and predators of insect populations in lowlandrice ecosystems in the district Tombatu Southeast Minahasa regency. The experimentwas conducted on the rice in the village Tombatu, District Tombatu, SoutheastMinahasa Regency. The research carried out by the survey on rice crops in the districtTombatu Southeast Minahasa District, the Village Tombatu One, Tombatu Two, andThree Tombatu. Sampling was carried out with a diagonal slice method thatestablishes five sub-plot that is on the corner and the middle of the sampling sites.Sampling was performed using insect nets swung over rice plant as much as ten timesthe double swing. Insects are netted immediately put into "killing bottle" thencollected in 70% alcohol to be identified. Identify the type of insect predatorsconducted using the facilities of Entomology and Pest Plant Laboratory, Faculty ofAgriculture UNSRAT. The research found seven insect predators with an averagepopulation Menochilus sp. (5.18 tail) Paederus sp., (3.34 tail), Agriocnemis spp. (2,24tail), Conocepalus sp. (1.10 tail), Ophionea sp. (0.68 tail), Sphecidae (0.52 tails), andLibelulla sp. 0.27 tails). On average the highest predator insect populations found inthe village Tombatu Two (4.55 tail), then the Village Tombatu One (1.07 tail) and thevillage of Three 0.91 Tombatu tail). The higher the age of the plant the morepredatory insect populations.

Abstract

ABSTRACT  Cabbage moth (diamondback moth), Plutella xylostella (Lepidoptera: Plutellidae) is a major pest that is very damaging on plant family Brassicaceae, especially cabbage plants. The study aims to determine parasitation P. xylostella in cabbage planting and Brassiscae area in Tomohon. This study uses survey at four locations in Tomohon, namely Rurukan village, Kumelembuay village, Wailan village and Kakaskasen Two village. Results of the study was only found one type of parasitoids that attack Plutella xylostella in the Tomohon city. Identification results showed that parasitoids that attack the larvae / pupae of P. xylostella is Diadegma semiclausum. The average percentage of parazitation D. semiclausum against P. xylostella in Tomohon highest found in location of Rurukan village (82.01%), Kumelembuay village (76.58%), Wailan village (73.37%) and the lowest in the Kakaskasen Two village (71.94%).  Key word : Cabbage, Plutella xylostella, Diadegma semiclausum

Abstract

Spodoptera frugiperda is a new pest that entered Indonesia around 2018 and acts as the main pest that causes young corn plants to be damaged and experience growth problems. It is known that there is a natural enemy, namely the parasitoid Trichogramma sp. which can attack S. frugiperda eggs. The research method can be carried out by experimenting with the development and multiplication of the parasitoid Trichogramma sp. in the laboratory using a previously cultured population of C. cephalonica eggs as a host. The results showed that the multiplication of the egg parasitoid Trichogramma sp. with alternative host C. cephalonica can be done in the laboratory. Biological development in the form of the life cycle of the parasitoid Trichogramma sp. can be known based on observations, namely the egg stage is around 14-15 hours, the first instar larva stage is 22 hours, the second instar is 24 hours, the third instar is 25 hours, the fourth instar is 26 hours, the pupa stage is 28 hours, the lifespan of adult female insects is 10-12 days while the male 10-11 days. Percentage of parasitization of Parasitoid Trichogramma sp. the population of the S. frugiperda pest egg group in the field was quite high, ranging from 68.5 – 87.3 percent with an average of 76.5 percent.
