Abstract

The research is aimed to confirm the potency of several botanical pesticides to be used as natural biological control and to know the most infective stadium of T. kanzawai was done at Pest and Disease Laboratory of Indonesian Tropical Fruits Research Institute from May to August 2009.  A factorial completely randomized design was used in this research.  Two factors were observed; first, four kinds of botanical pesticides consist of four treatment levels i.e. extracts of neem, soursop, Siam weed leaves and sterilized water as control.The second was the stadia of T. kanzawai that consist of three levels i.e. larva, nymph and adult.  The result showed that Siam weed and soursop leaves extracts caused anti-feedent behavior and decreased mobility at five days after treatment.  In addition, exoskeleton of treated T. kanzawai darkened from white, yellowish and bright brown.  Extracts of Sourshop and Siam weed leaves caused very high mortality (96.67%) of T. kanzawae compared to neem (79.17%).  However, there was no significant difference in mortality rates among the four active stadia of T. kanzawai with average mortality range from 65.63% to 79.38%. Keywords: botanical pesticide, T. kanzawai, control

Abstract

Factors involved in the mechanism of resistance of soybean to pod sucking bug R. linearis  were identified using resistant soybean genotypes, IAC-100, and IAC-80-596-2 and the susceptible variety, Wilis as a check. The role of trichomes in resistance was assayed removing trihomes from the pod shell, and seed coat  and  the resistance was determined based on the number of stylet punctures made by the bug. Seed of IAC-100 and IAC-596-2 that had longer, denser trichomes, higher crude fiber content and  suffered fewer stylet punctures than  Wilis. This suggested that denser and longer trichomes interfered with stylet piercing of the pod shell. When the trichomes of IAC-100 and IAC-596-2 were removed these genotypes were more susceptible to insect feeding. In further studies, replacement of IAC-100 and IAC-596-2 seed with seed of Wilis in the pods of resistant genotypes resulted less stylet punctures on the Wilis seed. It was concluded that denser and longer trichomes on pods along with harder pod shells acts as a physical barrier in antixenosis resistance of soybean to the pod sucking bug. Therefore, IAC-100, and IAC-596-2 genotypes have good potential for used as resistant parents in a soybean breeding program.     Keywords: resistance, pod characters, tri-chomes, antixenosis, pod stink bug

Abstract

Rock phosphate is a slow release phosphate source which can be directly used on acid soils. There are some rock phospahate deposits in Indonesia. Total phosphate and calcium content in rock phosphate vary between 8.79 – 31.88% P2O5, and  0.60 – 57.50% Ca. The objective of these research is to study the Indonesian rock phosphate effectivity for maize on Ultisol soil. The research wasconducted at green house using randomized complete block design, 8 treatments and 5 replications. The treatments consist of 5 kinds of different Indonesian rock phosphate, control, supherphos fertilizer and Tunisia Rock Phosphate as a standard comparison of P fertilizer.Relative Agronomic Effectivenes Analyses was used to see the effectivity of each  rock phosphate. The result of these study shows that the effectiveness of Rock Phosphate from Jampang Tengah Sukabumi (DE-1), Brati Kayen Pati (DE-9), Padaherang Ciamis (DE-3), and Karang Mulya Ciamis (DE-5) were aqually the same as Superphos. Indonesian Rock Phosphate’s effectivenesswas almost the same as Tunisian Rock Phosphate. Phosphate fertilizing using rock phosphate obviously increased the soil content of phosphorus, both the available P and the reserved ones, and Superphos did better than the rock phosphate. Rock phosphate effectivity on Typic Plintudults was lower than thaton Typickanhapludults.   Keywords:   rock phosphate, effectivity, typicplin-thudults, typickanhapludults, maize

Abstract

Human activities in seeking agricultural lands, has change the traditional agricultural system into intensive cultivation system. One effort to minimize intensive agriculture system is the use of natural enemies to control pests. Habitat management should be implemented by creating habitat favored by natural enemies. This research aims to determine the spatial and temporal distribution of natural enemies of wild plants: Mimosa pudica, Vernonia cinera, Marsilea crenata, and Pistia startiotes on agricultural land. This research was conducted in March-April 2010 in Malang Sawojajar farmland. Plants placed in the corner field (refugia areas), visiting insects was observed starting from refugia areas and two meters away from the refugia area. Observations of insect use the "visual control" metode. The results showed that natural enemies visiting to the refugia areas were 6 orders (15 families): Coleoptera, Odonata, Aaraneae, Hymenoptera, Diptera, and Orthoptera. Not all natural enemies have spatial and temporal distribution, only 9 families who indicate a pattern spatial or and temporal distribution. Overall, natural enemies do not show any significant spatial pattern (F> 0.05), but indicate a temporal pattern (F

Abstract

Vetiver oil (Vetiveria zizanoides) is one of Indonesia main export commodities. Vetiver root is perennial plant and generally planted with vegetables as intercropping plant. Increasing the selling price of vetiver oil can be done by transferring the production of conventional vetiver oil (non-organic) to organic vetiver oil. Demonstration of land used was one hectare, which 2,000 m2 for planting vetiver root with potato (Solanum tuberosum) as inter-cropping plant and 8,000 m2 for vetiver root without intercropping, in Sukakarya-Samarang, Garut. The planting used goat and cow dung as manure, distillate water of vetiver oil and liquid bio-pesticide as pesticide. Variables studied included plant height, number of leaf and crotch. In the first quarter of the years, the number of leaf and crotch of vetiver root with intercropping was better than vetiver root without inter-cropping. However, there was not significant difference for plant height of vetiver root, both with and without intercropping. Products of organic potato as intercropping plant of vetiver root were less than those of non-organic potato, but the latter had a better texture and durability.   Keywords: Vetiveria zizanoides, Solanum tube-rosum, intercropping, organic farming

Abstract

The research aims to know the life cycle, feeding and mating behavior of predatory beetle S.  gilvifrons, and was conducted at entomology laboratory of Assessment Institute for agri-cultural technology Malang - East Java. The treatments involved feeding behavior and capacity of the various instars and imago of S. gilvifrons. The number of mites consumed within 24 hours by each stage of beetle was also recorded. The average voracity of five individual predators for each instar was determined.  The result showed that average life cycle of S.  gilvifrons feed on E. orientalis was 4.11 + 0.78; 8 + 1.10; 3.83 + 0.41, respectively for egg, larva and pupa.  The predator caught the preys from the front side, then chewed and sucked the body contents of adult preys or consumed the whole egg.  The feeding capacity was greater in egg-laying than that in non egg-laying females and males.  The smallest size of the cage (1.5 cm diameter x 5 cm long) and clear weather were the most preferred situation for S.  gilvifrons mating, which  usually occurs on the upper leaf surface.  The male positioned itself over the female body and extended its aedeagus to reach the female.    Keywords: Life-history, Stethorus gilvifrons, phytophagous mites

Abstract

Priming is a process that controls the process of hydration of seeds for the ongoing metabolic processes before germination.  Research on   priming   was conducted  at  ICERI seed laboratory  from May to September 2009  to evaluate the  effect of different priming methods on  wheat seed vigor. Physical properties and chemical composition of seed were evaluated before seeds were treated. The priming treatment were conducted by soaking 250 g of seed in  500 mL of  solution for hydropriming and halopriming.  Two seed lots of Nias and Dewata variety were subjected to heated and unheated  distilled water for 12hours and subjected  to  KCl and CaCl2  at 10, 20, and 30 ppm and unprimed seed. The experiment were arranged in completely randomized design,  replicated thrice.  Vigor evaluation by observed  seed germination, simultaneity growth, germination rate, seedling dry weight, electric conductivity of seed  leakage and  length of primary root.   The results showed that highest  germination,  simultaneity growth, seedling dry weight, and length of primary root,  were priming treatment    with  KCl  30 ppm  and CaCl2  20 and 30 ppm.  Priming  with distilled  water for 12 hours gave  higher  germination percentage  and  simultaneity growth.   Keywords : priming, wheat, seed, vigor

Abstract

Riptortus linearis represents the most common pod sucking pest on soybean. Genetic studies on inheritance of resistance to the pest are needed. The study used B4400 and B3802 genotypes as resistant parents, Tambora as susceptible parent. Crosses were made to form F2 population of Tambora x B4400, and Tambora x B3802. A total of 10-20 seeds each of resistant and susceptible parents, 220 F2 seeds of Tambora x B4400 crosses, and 232 F2 seeds of Tambora x B3802 crosses were grown in pots, one plant/pot. The plants were infested with adult R. linearis (riptortus), at the R2 stage. The results showed that the population of riptortus in each of the F2 soybean population at 7 and 15 days after infestation were >2 insects/25 plants, which enables the study of genetic resistance to soybean pod sucker. Heritability values indicated that resistance to pod sucker was controlled by genetic factors. The resistance to riptortus in B4400 and B3802 genotypes was controlled by two recessive genes located at different loci, and interacted with each other with epistatic dominant reaction. With an assumption that B and C genes were dominant, hence the resistance genes found in both soybean genotypes were bbcc.   Keywords: genetic resistance, soybean pod sucker Riptortus linearis L.
