Abstract

Feeding rate, aestivation and mobility of golden snails (Pomacea canaliculata) at different depths of water. The research was studied in Malaka District, East Nusa Tenggara Province, during the dry and the rainy season (October 2014 - March 2015). Studies on capacity of damage to the Ciherang rice seedlings were carried out for three weeks. The size of snails used in this experiment was 11-20; 21-30; and 31-40 mm. The numbers of seedlings that were planted were 3, 6, 9, 12, 15, 18 and 21 seeds. The treatments were repeated 5 times. The numbers of seeds which are damaged by the snails then were tabulated and analyzed. Snails with the size of 11-20 mm damaged the seeds in 31.67%, followed by snails with the size of 21-30 mm and 31- 40 mm with potency of damaging were 64.76% and 97.38%, respectively. The size of snails affects the level of damage to rice seedlings when transplanting. Study about aestivation was conducted in five villages, namely Kamanasa, Wehali, Umakatahan, Harekakae and Kletek when the rice fields were fallow. The observation point was observed at the corner of the dike and along the dike, evaluated every 10 meters away. The results showed snails aestivate when the fields were dry. Studies on snail’s mobility conducted on the experiment arena on the mud in buckets, which planted with 20 paddy seedlings. The treatment depth of puddles in the experiment were without puddles, half, the same height and twice the height of snails shell. The treatments were repeated 10 times. Measurement of snail’s mobility was performed routinely every 2 hours, observed from the beginning when the snails were placed for 24 hours in advance. The results showed that the depth of the water significantly affected the mobility of snails. Without puddles, the mobility of snails was severely hampered in the mud. The mobility of the juvenile was significantly higher than the imago. The implication of this study was benefit to that the regulating the level of water in the paddy field which is known as an appropriate effective technology and for controlling the attack of the golden snails.

Abstract

The fruit fly Bactrocera dorsalis complex is important pest on citrus plantation at highland Karo district North Sumatera Province. The studies with the aim to find out its daily activity pattern and population dynamic on citrus plantation have been done. Fruit flies were collected by water bottle trap with methyl eugenol attractant. Sampling for daily activity pattern was done per two hours for two months (April to May 2011) from 06.00 a.m until 18.00 p.m. Meanwhile, population dynamic study was conducted on two citrus plantations per four days for nine months (March to November 2011) in the first and third week of each month. The research result showed that B.dorsalis complex was more active during morning at 10.00 to 12.00 a.m. The peak abundance of fruit fly occurred at the end of June until beginning of July. The peak population coincided with the ripening period of fruits, low number of rainy (d) and rainfall (mm) in June and July periods. There was a significant correlation between number of rainy day and rainfall with fruit flies caught per month (R = 0.79; Y = 289.34+14.23X1-15.93X2; R2 = 0.62; P < 0.05). The pattern of fruit fly fluctuation in two citrus plantations was similar (rs = 0.47; P < 0.05).

Abstract

Screening Method for Chilli Veinal Mottle Virus (Chi VMV) and Cucumber Mosaic Virus (CMV) Resistance in Chillipepper. ChiVMV and CMV have been reported as the causal agents of main diseases in chillipepper in Indonesia and other Asian countries. Mix infection of this two viruses was commonly occurred in the field, causing severe disease . The use of resistance varieties has been proposed for dealing with the yield losses causing by the viruses. Breeding program is undergoing for development of chillipepper varieties resistant to ChiVMV and CMV. Methodology for routine screening activity of chillipepper for resistance to both ChiVMV and CMV needs to be established. This research was conducted in Cikabayan Glass House and Plant Virology Laboratory, Plant Protection Department, Bogor Agricultural University from May 2006 to June 2007. Aim of the research was to develop screening method for simultaneous infection by the two viruses, ChiVMV and CMV. Inoculation of ChiVMV and CMV was done by single inoculation or repetitive inoculation methods. In both methods, ChiVMV and CMV were inoculated in different sequences, either ChiVMV or CMV first. The result showed that incubation period was shorter when CMV was inoculated in advance both in single and repetitive inoculation method. Mosaic, mottle and malformation type symptom was observed in infected plants. Based on disease incidence, infection of ChiVMV was higher compared to CMV in repetitive inoculation as well as in single inoculation. Repetitive inoculation methods with virus sequence ChiVMV-CMV-ChiVMV-CMV was selected for resistance evaluation of chillipepper genotypes.

Abstract

Molecular identification of bean common mosaic virus associated with yellow mosaic disease on yard long bean. Bean common mosaic virus (BCMV) has been reported as one of the causal agents of yellow mosaic disease on yard long bean in West Java and Central Java. Infected plants showed mosaic, yellowing, and mixture of yellow mosaic. The research was conducted to identify the diversity of BCMV associated with yellow mosaic disease based on coat protein (CP) gene sequences. Symptomatic leaf samples were collected from yard long bean growing areas in several districts in West Java (Bogor, Cirebon, Subang, and Indramayu), and several districts in Central Java (Tegal, Klaten, Solo, Yogjakarta, Sleman, and Magelang). Molecular detection using RT-PCR method was carried out by using specific primer to BCMV which will amplify the CP gene. DNA fragment, + 860 bp in size, was successfully amplified from 8 out of 13 leaf samples, i.e samples from three villages in Bogor District (Cangkurawok, Bubulak, Bojong), and five samples from District of Cirebon, Subang, Solo, Sleman, and Tegal. Sequence analysis of those DNA fragment showed that 4 isolates (Bogor-Cangkurawok, Subang, Solo and Sleman) had the highest homology to BCMV-BlC from Taiwan, whereas 2 isolates (Cirebon and Tegal) had the highest homology to BCMVNL1 from England. Further, phyllogenetic analysis revealed that those of 4 isolates were closely related to BCMV-BlC from Taiwan based on nucleotide as well as amino acid sequences; while those other 2 isolates were closely related to BCMV-NL1 from England based on nucleotide sequences but closely related to BCMV-BlC Y from China based on amino acid sequences. Phyllogenetic analysis showed that those of 6 BCMV isolates separated in two different clusters; 4 isolates (Bogor- Cangkurawok, Subang, Solo, and Sleman) in cluster 1 together with BCMV-BlC from Taiwan, while other 2 isolates (Cirebon and Tegal) in cluster 2 together with BCMV-NL1.

Abstract

Association of mealybug, Dysmicoccus brevipes (Ckll.) (Homoptera: Pseudococcidae) and fire ant, Solenopsis sp. (Hymenoptera: Formicidae) on two pineapple&ndash;planting patterns. A pineapple mealybug, Dysmicoccus brevipes (Ckll.) (Homoptera: Pseudococcidae) is an important insect pest in major pineapple growing areas. Its feeding activity causes damage on the pineapple plants and it can also transmit pineapple wilt virus. The mealybugs are often found in association with fire ants, Solenopsis sp. (Hymenoptera: Formicidae) that provide protection in exchange for the sweet honeydew liquid. The field study was conducted to determine the close association between mealybugs and fire ants on two plant row spacing (single and double row spacing) four different plant stages (3, 7, 11, and 17 months after planting). The results indicated that there was a significant correlation between the mealybugs and the fire ant on two pineapple-planting patterns, particularly on late growth periods (11, and 17 months after planting). In this field study, population of mealybugs on double row spacing were more abundant (ranging from 0 to 25.67 bugs/plant) compared with that on single row spacing which ranged 0 to 3.67 bugs/plant. Moreover, general mean of population density of mealybugs (14.53 bugs/plant) on double row was significantly higher than that on single row spacing (1.83 bugs/plant). In line with this mealybug-population development, mean numbers of fire ants caught on baited-sticky traps were ranged from 0 to 8.53 ants/trap on single row versus 0 to 23.57 ants/trap on double row spacing pattern. The general mean number of captured ants (12.73 ants/trap) on double row was significantly higher compared with that on single row spacing (5.55 ants/trap). It appears that the patterns of population densities of mealybugs are closely related to that of fire ants that act as attendant species on two pineapple row spacing.

Abstract

The adzuki bean weevil Callosobruchus chinensis is the main pest of mungbean especially during seed storage. Mungbean generally has low yield and is susceptible to main pests. Ricebean (Vigna umbellata (Thunb.) Ohwi & Ohashi) has superior characters such as the high pod number per plant and resistance to many pests. The interspecific hybridization was conducted to combine the superior characters of mungbean and ricebean. The objectives of this research were to evaluate resistance of hybrids of interspecific hybridization between mungbean and ricebean to C. chinensis and to determine pattern of resistant inheritance. Evaluation of resistance to this pest was conducted in bottles by placing 200 hybrid seeds and then 20 C. chinensis adults were introduced into the bottle covered by dense cheese cloth. The bottles were arranged in a completely ramdomized design with three replications. The treatment consisted of eight hybrids and six parents. The results showed that the resistance of the test hybrids to C. chinensis was different among cross combinations. Hybrids of crossing between mungbean Merak variety and yellow ricebean as well as Vima variety and red ricebean were moderately resistant, while the others were resistant. There was resistance improvement of hybrids to C. chinensis. The resistance of the hybrids to C. chinensis was controlled by single gene with partially dominance gene action.

Abstract

Soybean lines selection of F4 population resistant to soybean mosaic disease (Soybean mosaic virus) with high yield. The soybean breeding program is usually not purposedly done for resistance to Soybean mosaic virus (SMV) but rather for crop yields. The experiment was aimed to obtain soybean lines of F4 population resistant to soybean mosaic disease with high yield. F2-F4 plants that have been inoculated with the T isolate of SMV one week after planting were selected by the pedigree in the screen house. The result indicated eight F4 populations (Wilis x L. Temanggung; Wilis x L. Jombang; Wilis x Pangrango; Wilis x PI 200485; Gepak Kuning x L. Jombang; Gepak Kuning x L. Temanggung; Gepak Kuning x Malabar; Gepak Kuning x PI 200485) produced medium seed size (from 9.84-10.26 g 100/seeds). Gepak Kuning x Mlg 3288 showed more resistant than Gepak Kuning x PI 200485. The seed produced by Gepak Kuning x PI 200485 was 1.97 ton/ha. There were no F4 populations that had higher yield and bigger seed size than Gepak Kuning x PI 200485 even though they were moderately resistant to SMV. Therefore, these lines of Gepak Kuning x Mlg 3288 and Gepak Kuning x PI 200485 might provide exellent sources to develop a new variety that resistant to SMV and of high yield.

Abstract

Parasitism of Hemiptarsenus varicornis (Girault) (Hymenoptera: Eulophidae) on leafminer fly Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) on kacang endul (Phaseolus vulgaris L.) in Ciloto, West Java. The objective of this research was to elucidate the relationship between leafminer and its parasitoid abundants. The research was conducted in Ciloto (Cianjur), West Java in 1999. The miner infested leaves of kacang endul were collected and placed in plastic bowls. The emerged parasitoids from those leaves were counted. The result indicated that the level of parasitism of H. varicornis during the plant growth stage ranged from 39 to 50%. The perfect density dependent between percentage parasitism and the leafminer abundance was experimentally proved.
