Shellac flea Laccifer lacca Kerr is a phytophagous insect, which lives on kesambi tree (Schleichera oleosa Merr). During its life cycle, shellac flea secretes liquid known as LAK and has many uses, such as varnish/polish, food cover, drug capsule, cassette ribbon, etc. In 2005, Perum Perhutani produced 60,547 kg LAK pellets, but has not fulfilled market demand. Cultivation technique is still conducted in a very simple way. Investment in developing shellac flea is also profitable, and promising. There are two choices of management schemes in it cultivate, the first is by infecting shellac flea to the host tree when the tree is 15 years old and the second is by infecting shellac flea when the tree is 4 years old. Financially, the latter approach is more beneficial than the former one. The value of NPV + 22 321 052 395, IRR 16.9%, BCR 1.55 and Net B/C 3.71 with discounted payback period for 10 year 8 months. SWOT analyzing was used in the design strategy as a management approach.

Endophytic fungi is an endosymbiont that lives within host plant tissues and does not necessary cause any harm to plants. This type of fungus are important as mediators in plant-herbivore interactions. One of the endophytic fungi in rice is Nigrospora sp. The effects of Nigrospora sp. on the biology and demographic statistic of Nilaparvata lugens Stál (Hemiptera: Delphacidae) were studied in the laboratory. We used Nigrospora sp. culture powder was used to inoculate the fungi to rice seeds by mixing 10 g of flour endophytic per 1 kg rice seeds. The mixture was then stored in damp and dark storage. Results showed that the rice seeds treated with endophytic fungi showed some resistance to N. lugens. Eggs and early stages of nymph mortality was increased, higher than the control. Endophytic fungi also affect the nymphs growth rates by slowing it down, prolonging N. lugens life cycle, preoviposition period as well as delayed the age at first reproduction. N. lugens population growth is effected by Nigrospora sp. in laboratory scale. Thus, it has the potential as an alternative way to control N. lugens population. In addition, inoculation of endophytic fungi could be a useful method for protecting rice plants from N. lugens.

Berry sucker insect pest, Dasynus piperis china (coreidae; Hemiptera) is one of the major insect pest on pepper. D. piperis to attack fruit of pepper with suck of fruit liquid and the final effect is empty to fruit and damaged. To find out of the level of damage and destruction caused by D. piperis have been done at 6 districts of Bangka Island namely Mendo Barat, Sungai Selan, Sungai Liat, Belinyu, Koba and Toboali since January to December 2002. For each district were observed 5 farmers field of estate crops. Every farmer field were observed tens plant of pepper in connection with fluctuation population and level of fruit damage. The observation have been done on the flower season of pepper, after flower season and after harvest. The result showed that fluctuation population and infested level of D. piperis at each observation almost the same, while among district were variated. The highest infestation was found in Sungai Selan, followed by Belinyu, and Mendo Barat namely 36.82;32.03 and 29.48 % respectively. The infestation level on Sungai Liat, Toboali and Koba were low namely 14;79.58 and 20.98 % respectively. The level of damage in Mendo Barat was highest than an other location namely 8.66; 8.07; 6.67; 5.71;4.89 and 3.09 % in Mendo Barat, Sungai Selan, Belinyu, Koba, Toboali and Sungai Liat respectively.

Abundance and diversity of herbivorous insects are not only determined by the trophic level above, but also can be affected by the trophic level below it. This research aims to study the community of herbivorous insects and parasitoids on pods of different types of legume crops in Padang. The method used in this study was a survey method. This method was done by collecting pods of legume plants in various habitats. Insects contained in pods were maintained until adulthood. Individual insects that did not emerge from the pods were removed by dissecting pods. This method was also used to estimate the number of seeds, good seeds were damaged or not damaged in each pod. The results of this study indicated that the composition of herbivorous insects on legumes, especially legume Crotalaria striata was dominated by Eucorynus crassicornis, while the parasitoid composition was dominated by Braconidae. E. crassicornis has a wider range of expansion compared to other herbivorous insects. The insects were found on three types of legum C. striata, Crotalaria sp., and Leucaena leucocephala, whereas other types of herbivores attack only two types of legumes. The highest percentage of damage was obtained in Crotalaria striata i.e 74.53%.

Fungicide is one of the common pesticide applies in agriculture. Even though fungicide is specifically designed to prevent growth of fungi, some studies reported neurotoxic effects of fungicide to some tested animals. Therefore there are concerns about the possible determintal effects of fungicide to beneficial non target organisms, like pollinating insects. This study was conducted to determine the toxicity of commercial fungicide to pollinator, Trigona (Tetrgonula) laeviceps Smith, by determining the LD50 and hazard quotient (HQ). The fungicides tested were triazole (tridimefon and difenoconazole), propamorcab (propamocarb HCl), and dithiocarbamate (mancozeb and propineb). Forager bees were collected and anasthesized by exposing the bees to low temperature (-10 oC) for 1 min. About 1 µl of tiadimefon (6,25; 12,5; 25; 37,25; 50 µg/bee), difenoconazole (1,25; 2,5; 5; 6,25; 12,5; 25 µg/bee), propamocarb HCl (72.,25; 144,5; 216,6; 361,25; 433,5 µg/bee), mancozeb (1,6; 3,2; 4,8; 6,4; 8 µg/bee), and propineb (0.9; 1.8; 2.7; 6; 8.4; 16.8; 25.2 µg/bee) were applied using topical application on dorsal area of bees. Ten bees were used for each concentration and replicated 3 times. Mortality of bees was recorded for 48 hours. Results showed that LD50 and HQ for each tested fungicide were as follow: triadimefon LD50 13.43 ±1.78 µg/bee, HQ = 18.62; difenoconazole LD50 9.25 ± 1.21 µg/bee, HQ = 27.03; propamocarb HCl LD50 270.45 ± 19.48 µg/bee, HQ = 14.34; mancozeb LD50 3.75±0.47 µg/bee, HQ = 512; and propineb LD50 9.71 ±2.20 µg/bee, HQ = 144.18. Among all 5 tested fungicide, two fungicide, mancozeb and propineb, has intermediate level of toxicity to foragers of T. laeviceps and could produce determintal effect to colony.

Spiders are the main predators in paddy ecosystem. Application of entomopathogenic fungus, such as Beauveria bassiana (Balsamo) is not expected to have any negative effect on spiders in the paddy field. This research was aimed to compare species composition, abundance, and species richness of spiders in ratoon paddy. The research was done on three hectares of rice fields that were treated with the following treatment, (i) 2 L/ha/application of liquid B. bassiana, (ii) 2 L/ha/application compost extract (without liquid B. bassiana), and (iii) a combination of liquid B. bassiana and compost extract with each using the same 2L/ha/application dose. The result of this research showed that B. bassiana bioinsecticide application did not affect the abundance and species richness of spiders in ratoon paddy. The treatments did not significantly affect species richness and abundance of the canopy-inhabiting spiders. The species richness and abundance of the soil-dwelling spiders on the paddy field applied by the bioinsecticide was not different from those without the bioinsecticide. The treatments did not effect species composition of the canopy-inhabiting and the soil-dwelling spiders. Application of B. bassiana bioinsecticide was not harmful for the spiders in the rice field.

Feeding supplementary food containing nony fruit juice was tested on honeybee colonies in honey producing . The aims of this research were (1) to determine the preference level of honeybees to the supplementary food containing honey and nony mixture, (2) to identify the organoleptic properties of the produced honeyessence of nony, (3) to determine fiber content of produced honey-essence of nony, and (4) to identify the colours of honey produced. The design used in the experiment was Latin Square Design. There were four treatments namely each concentration : A (0%) as control, B (12,5%), C (25%) dan D (37,5%) in dilution of supplementary food an amount of 600 grams wich consist of nony fruit juice and water. Each composition of dilution were A (300, 0, 300), B (225, 75, 300), C (150, 150, 300) dan D (75, 225, 300) . Every one replication was done for six days with six day interval. The result were as follows: The higher concentration of nony juice in the food suplement the smaller food were taken. The differences in the olour, the flavour and the taste of the artificial honey didn’ depend on the amount of the food suplement taken honey bees, but depend on nony fruits juice concentration in the honey produced. The higher concentration of nony fruit juice in the artificial honey produced the darken in colour, sour in taste and the weaken in flavour. Feeding with food suplement containing nony juice increases the fiber content in the honey.

The aim of this research is to evaluate the change of Aedes aegypti L. and Culex spp. larvae morphology effected by chitinolitic bacteria as larvacide. This research was conducted in Microbiology Laboratory, Faculty of Math and Natural Science, University of Syiah Kuala. The sample was taken from several areas in Banda Aceh and Aceh Besar. The isolation was accomplished by plating 1 ml of sample water on chitin agar medium and incubating for 48–72 hours in 30 °C temperature. In the experimental method, three concentrations of chitinolitic bacteria (0.5, 1.0, and 1.5 ml) in 7 days observation were used as a treatment. The research resulted in 6 isolates having the potential to be developed firther as chitinolitic bacteria. The result shows that chitinolitic bacteria degrades exosceleton of second instar larvae of Aedes aegypti and Culex spp. Degradation of exoskeleton started on the 4th days and occurred at the thorax region. All exoskeleton from both species are completely broken on day six.

Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) is one of the most important pests on cotton. Yield losses due to this pest can reach up to 70%. Pest control using the NPV has been proven to be effective in the field. However NPV isolates from different geographical locations could be showed variation in genetic and their biology. The purpose of this study was to compare morphology, biology, and molecular characteristics between three HearNPV isolates from cotton field in South Sulawesi, Central Java, and East Java. Scanning electron microscope (SEM) was used to look at morphological characters, whereas biological characters were observed by dipping shelled of young corn cob on each isolate suspension with a density of 2.5 x 103, 2.5 x 104, 2.5 x 105, 2.5 x 106, 2.5 x 107 POBs /ml and control then fed to the first instar larvae of H. armigera. Probit analysis was used to determine LC and LT. The molecular assay used polymerase chain reaction (PCR) with lef-8 gene. The results showed that the three isolates had the shape and size of polyhedra which was not significantly different with the mean diameter were 0.86 μm. The result showed that in 7 days post infection, HearNPV isolate from East Java was the most virulent isolates with the lowest LC50, which is 6.38 POBs/ml, but lowest LT50 value in 2.5 x 107 POBs/ml were showed both from East Java and South Sulawesi, which are 2.7 days post infection. Meanwhile, the DNA sequencing of the three isolates showed a high similarity (100% homology).
