Development of resistant rice varieties to brown planthopper (BPH, Nilaparvata lugens Stål) must be countinuously conducted to overcome the spatial and temporal genetic change in BPH into more virulent ones which can adapt to resistance rice. The availability of linked molecular markers with BPH resistant trait can speed up selection of hybridization progenies. Close-linked markers with trait of interest can be identified using association studies between markers and phenotypic data of unrelated individuals without the need to generate hybridization progenies as an alternative method to linkage studies which use mapping population. The objective of this study was to analyze the association of rice simple sequence repeat (SSR) markers with resistance to BPH. Forty-four rice varieties and promising lines with known resistance degree to BPH biotype 3 were assessed using 30 rice microsatellite markers previously mapped in the rice chromosomal regions with effects on resistance to BPH. Association test between SSR markers and BPH resistance scores revealed eight markers (RM17, RM38, RM125, RM144, RM250, RM287, RM328, dan RM536) which were significantly associated with BPH resistance (R2=0,18 to 0,89; P<0,05). Twenty-one varieties and 11 promising lines were detected to contain SSR alleles that were associated with BPH resistance. Marker RM17 was detected in 15 varieties and 11 promising lines which were scored as resistant and moderately resistant to BPH and therefore it is potentially the most useful as early diagnostic marker to detect BPH resistance alleles. Nevertheless, to obtain SSRs that can be used as reliable selection markers for BPH resistance, marker analysis in segregating populations for the eight markers is still needed as well as association test of more SSR markers widely distributed in rice chromosomes.

Chrysanthemum (Chrysanthemum indicum) as one of horticultural commodities has a good prospect to be developed as source of country revenue. The export of cut flowers of chrysanthemum from Indonesia tends to increase year by year. However, Thrips parvispinus Karny (Thysanoptera: Thripidae) which is major insect pest of chrysanthemum often attacks this flower in the field until postharvest causing the decrease of quality of flowers. The poor quality of cut flowers of chrysanthemum including the presence of T. parvispinus will be rejected by foreign businesses. Therefore, control measures of this insect pest by quarantine officers are important. Treatment can be done using liquified formulation phosphine fumigant. The objectives of this study were to determine the concentration of liquified formulation phosphine and exposure time which will were effectively kill T. parvispinus and to evaluate the quality of cut flowers of chrysanthemums treated with phosphine fumigant. T. parvispinus was exposed to liquied formulation phosphine at 9 concentrations (0, 25, 50, 75, 100, 125, 150, 175 and 200 ppm) with 3 exposure times (1, 3, and 6 hours). Moreover, validation test of concentration nd exposure time of liquified formulation phosphine on cut flowers of chrysanthemum was conducted to evaluate the quality of chrysanthemum cut flowers of treated with phosphine fumigant. Results showed that liquified formulation of phosphine at concentration of 200 ppm and on 1 hour of exposure time completely killed T. parvispinus by 100% mortality. At 200 ppm and exposure time until 6 hours did not affect the quality of cut flowers of chrysanthemum.

The objective of this research was to study the functional response of M. sexmaculatus. The hypothesis of this study was that age of predator and the numbers of prey will effect predation rate. To test this hypothesis, a set of prey (first and fourth instar and adult R. maidis) was separately placed together with first and fourth instar larval and adult female of M. sexmaculatus at different densities. The length of the exposure of the hosts were respectively 13, 14 and 2 hours for 1st instar larval predator, 4th instar larval predator and adult predators. In addition a combination of 1st and 4th instar nymph of R. maidis were exposed to adult M. sexmaculatus for 24 hours. The result of this study showed that the ability to predation of young and adult M. exmaculatus was type II, indicating that M. sexmaculatus can be categorized as effective biological control agent. Adults of M. sexmaculatus are better predators than the larval stages. Based on non linear regression analysis, the maximum numbers of preys consumed by adult females of M. sexmaculatus was 300 individuals of various stages of R. maidis per 24 hours.

Elaeidobius kamerunicus Faust is an oil palm pollinator insect that lives on the male inflorescence and visits female inflorescence to pollinate due to attracted by its volatile compound. The number of fruit sets of oil palm relates to the population of E. kamerunicus on a plantation. The objective of this study was to investigate the effect of age of oil palm on the population of E. kamerunicus. Field research was conducted in oil palm plantations that located in Pangkalan Lada, Kotawaringin Barat District, in Central Kalimantan. The research method was by measurement of E. camerunicus population on male inflorescences and set up the sticky trap on female inflorescences. Plot with size 7000 m2 (100 trees) was selected on several ages of oil palm i.e. 6, 10 and 16 years. Each plot, the number of male and female inflorescences was counted and some inflorescences were chosen for measurement of E. camerunicus population that was conducted monthly for three months of observation. The results showed that the age of the oil palm affected the population of E. kamerunicus in male inflorescences but not in female inflorescences. The older age of oil palm, the population of E. kamerunicus in male flowers was increasing. The sex ratio of E. kamerunicus found in male and female inflorescences of oil palms tend to female bias. Based on the comparison of E. kamerunicus population between male and female inflorescences on each plot, it was found that visitation value of E. kamerunicus was highest in the young oil palm. In conclusion, increasing age of oil palm trees affected on increasing of E. kamerunicus population in male inflorescences, but visitation value on female inflorescences prone to decline.

Study on the diversity of insect visitors on tomato flowers were conducted at Bina Sarana Bakti (BSB) organic farm, Cisarua, West Java. Diversity of insects were observed by observational method, an 10 m2 area of tomato plants in the morning, mid-day, and afternoon. Observations were conducted during 20 days. Diversity of visiting insects were analyzed by Shannon diversity and its evenness. Similarity of visiting insects between time of observations were analyzed by Jaccard similarity index. In organic farm, insect visitors of tomato plants consist of six orders belonging to eight species. Insect visitors of tomato flowers were dominated by Thrips sp. (Thysanoptera) and Hylaeus sp. (Hymenoptera). Hylaeus sp. was a main pollinator of tomato plants. Diversity of insect visitors in the morning and mid-day was higher than in the afternoon. Evenness of insect visitors of tomato flowers between observation times were relatively equal.

This study was carried out on three soybean farms located in the Liverpool Plains Shire in New South Wales, Australia. The soybean farms were different in terms of pesticide type used. One of the soy crops was sprayed with broad spectrum synthetic pesticides (synthetic pyrethroids), one site of soy crop was sprayed with natural pyrethrum - an organically certified pesticide, and one of the soy crops was not treated with any pesticides. Arthropod samples were collected on three occasions at every site except in the third site of soy crops which was not treated with any pesticides. Samplings were done using sweep nets and beat sheets. There were no significant differences of community structure change between farms treated with different pesticide regimes (F2,5= 4.2599, P(perm)= 0.188), and no significant differences in arthropod species richness. The abundance of arthropods was significantly different for site treated with biopesticide and site treated with synthetic pyrethroids (G6 = 284.36, P <0.0001), non-sprayed site and site treated with synthetic pyrethroids (G6 = 2110, P < 0.0001), and non-sprayed site to site treated with biopesticide (G6 = 2027, P < 0.0001). The use of synthetic pesticides in agriculture has been found to suppress pests and beneficial arthropods, while the use of biopesticides or without pesticide, to some extent, may let beneficials thrive in the system and also may suppress pest arthropods.

Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) is the only known vector of banana bunchy top virus (BBTV). The objective of this research was to study the preference and suitability of banana aphid P. nigronervosa to various banana genotypes. Survey conducted at Talang Betutu, South Sumatra indicates the existence of different preferences of the P. nigronervosa toward different varieties in the field. Host suitability test was conducted using 13 banana varieties that were invested with P. nigronervosa from taro plants. Preference test was conducted using a 200 cm x 200 cm x 150 cm mesh cage that were used to house 13 banana genotypes that were invested with P. nigronerosa. The numbers of aphids on different banana genotypes were observed. Result of the study showed that “kepok” genotype was more suitable for the growth of P. nigronervosa compared to other genotypes. The suitability was shown by higher population, faster population growth, lower mortality and the higher proportion of alate adults. Banana kepok infested with 20 aphids at the beginning of the test reached 324 individuals within 24 days with population growth rate of 8.27% per day, and produced 1.9% of alate imagoes appeared 6 days after infestation. Host preference test using the same genotypes suggested that the aphid prefer banana kepok more than to any other genotypes.

Thrips parvispinus Karny (Thysanoptera: Thripidae) is one of the major pests of chili pepper in Indonesia. The pest can be found on all parts of the plants, especially flowers and leaves. Information of the biology and demographic statistic of T. parvispinus are still limited. The objective of this research was to study the biology and demographic statistic of T. parvispinus in Bogor. Fifty individual of 1st instar nymphs were reared on caged chili pepper leaves (d = 4 cm and h = 8 cm). Chilli pepper leaves were replaced everyday and observed daily to determine the development and number of offspring eggs. The collected data were used to obtain information about the biology of the pest such as the stadia of each instar, preoviposition period, life cycle, adult longevity, and fecundity. The data were also used to construct life tables for demographic statistic analysis using of the Jackknife method. There were 5 phases of immature stages of T. parvispinus: eggs, two instars nymph, prepupa, and pupa with their stadia were 4,79, 1,36, 3,54, 1,08, and 1,96 days respectively. The preoviposition period of the insect was 1,11 days, life cycle was 13,68 days, female longevity was 8,55 days, male longevity was 6,00 days, and fecundity was 15,33 eggs per female. The population development of T. parvispinus followed type III of survivorship curve with intrinsic rate of increase was 0,15 individual per days female per days, net reproductive rate was 5,71 individual per female per generation, generation time was 11,49 days and doubling time was 4,57 days.

Aedes aegypti (Linnaeus) (Diptera: Culicidae) is the main vector of dengue fever. In Indonesia, insecticides, especially pyrethroids, such as permethrin, have been effectively used to control Ae. aegypti. Notwithstanding that permethrin has been used since 1980s, information regarding the status and development of resistance of Ae. aegypti to permethrin is still limited and need further update. This study was conducted using the WHO standard test method. The aims was to determine the resistance status, and changes in resistance level of four field strains (Palu, Makassar, Bandung, Bogor) and susceptible strain (VCRU) of Ae. aegypti after the selection with permethrin for five generations. The results showed that resistance status of all field strains to permethrin were considered as high. The value of RR50 ranged between 10.5 to 25.7 fold. Bandung strain had the highest value of RR50 (22.5 fold), while Makassar strain had the lowest value of RR50 (10.5 fold). The fifth generation (F5) of five selected Ae. aegypti strains had the level of resistance 5 to 18 times higher than their parental. Knowledge of resistance status in a given area accompanied with the understanding about the development of resistance can be used to design a better vector management.
