Abstract

Toxicity n-hexane leaf extract Lantana camara and its active fractions were evaluated for their insecticidal activit  ies against Plutella xylostella larvae. The method included sample extraction, fractionation, and toxicity examination of leaf extract L. camara and its active fractions against P. xylostella larvae.  The extracts were applied by residue method.  Fractionation of active compounds from extract n-hexane was conducted by a vacuum liquid chromatography by using a stationary phase of silicate gel GF254­ and mobile phase of n-hexane, etil acetate, and methanol which produced five  fractions, that is fractions A, B, C, D, and E.  Leaf extract of  L. camara and its fractions possessed an insecticidal activity  causing mortality to P. xylostella larvae. The results showed that LC50 of crude extract at 3 and 4 day after applications was 0,936 and 0,651%, while LC50 of fractions A = 0,386 and 0,178%; fractions C = 0,327 and 0,132; fractions D = 0,617 and 0,318%; fractions E = 0,622 and 0,244%.

Abstract

The research of predatory arthropod species diversity in agro-ecosystem is very important because it affects the function of natural enemies in suppressing pest population. Management of paddy through cultivation method can be part of the conservation of predatory arthropods. This study was conducted to analyze and compare the diversity of predatory arthropod with method cultivation conventional and integrated crop management (ICM) and diversity predatory arthropod based on phase growth paddy from cultivation conventional and ICM. The experiment was conducted in lowland rice agro-ecosystem at two plots with conventional cultivation method and ICM. Sampling of predatory Arthropods was done on the phase growth vegetative and generative paddy using net trap, yellow pan trap, and direct observation in the plants. The results showed that the predatory arthropods found were from Insecta and Arachnida class. The species diversity of predatory arthropod at phase growth of generative was higher than vegetative phase both at the conventional and ICM cultivation. Diversity predatory arthropod on the ICM method was higher compared to conventional. Paddy cultivation method with ICM through the rational use of insecticides can be part of conservation for predatory arthropod species.

Abstract

Research on antifeedant activity of n-hexane leaf extract Lantana camara and its active fractions were evaluated for their insecticidal activity against Plutella xylostella larvae. The method included extraction, fractionation, and examination antifeedant leaf extract L. camara and fractions active against P. xylostella larvae.  Extract application was conducted using a residue feeding method. Fractionation of active compounds from extract n-hexane was conducted by liquid vacuum chromatography, using phase silent silicate gel GF254­ and phase mobility n-hexane, ethyl acetate, and methanol (elusion gradient), which produce fractions A, B, C, D, and E.  Extract leaf L. camara and fractions possessed antifeedant activity against P. xylostella larvae. Extract leaf L. camara at concentration of 1% caused larva antifeedant activity up to 78.47%.  Fraction E caused a higher larva antifeedant activity (85,52%) than extract and other fractions did.

Abstract

ABSTRACT A research on behavior of pest S. litura on two varieties of soybean has been done in Blang Manyak Village, Sawang Sub district, North Aceh District from January–May 2013. The research was arranged in a field experiment with two treatments of soybean varieties, that is Kipas Merah and Anjasmoro.  Each treatment was repeated 20 times to obtain 40 units of the experiment. Variables measured included damage intensity of S. litura, trichome density of leaves, yield components, and resistance evaluation. The relationships between yield components and damage intensity of S. litura were analyzed with regression and correlation. The results showed that damage intensity of S. litura on Kipas Merah was lower than that on Anjasmoro. Loss of soybean yield components on both varieties was influenced by the damage intensity of S. litura. There was a negative correlation between damage intensity of S. litura and soybean yield components on both varieties.  Kipas Merah was moderately resistant and Anjasmoro was susceptible against S. litura.  Resistance differences of both varieties were influenced by trichomes density of the leaves.

Abstract

The research was aimed at studying effects of potassium on the development of Aphis glycines populations and soybean yield. The experiment was conducted in Village Rayeuk Naleung, Sub district Tanah Luas, District North Aceh from July to September 2013. The experiment was arranged in a randomized complete block design (RCBD) with 3 replicates. The treatment was without fertilizer, potassium fertilizer at a dose of 25 kg/ha K2O, 50 kg K2O/ha and 75 kg K2O/ha. The variables observed were populations of A. glycines and components of yield soybean. The results showed that potassium at doses of 75 kg K2O/ha can reduce populations of A. glycines and soybean yield increase as compared to potassium fertilization at a dose of 25 kg/ha K2O  and 50 kg K2O/ha.

Abstract

The research was aimed at determining a critical period of soybean in competition with weeds. The experiment was conducted in Seunebok Baro Village, Sub-District Cot Girek, District Aceh Utara, from January to May 2013. The experiment was arranged in a randomized complete block design.  Factor evaluated was a period weed competition with 14 levels and three replications.  Variables observed were growth plant component, yield component, and weed compositions.   The results showed that period weed competition affected growth plant component and yield component.   Critical period of soybean variety Kipas Merah in competition with weeds occurred at 2 - 6 weeks after planting.  Dominant weed species were Dichrocephala integrifolia, Mimosa pudica, Ipomoea triloba, Ageratum conyzoides, Cleome rutidosperma, and Axsonopus compressus.  Minimum scale of weed control for soybean variety Kipas Merah can be carried out from 2 until 6 weeks after planting for preventing yield loss.
