Blood diseases caused by Ralstonia solancearum Phylotype IV is a major cause of production loss of banana in Indonesia, particularly for areas in West Sumatera. Currently there is a lack of information on blood diseases. The objective of this study was to obtain data of insect diversity and its potential as a dissemination agent of R. solanacearum Phylotype IV in West Sumatera. This research was conducted with a purposive sampling method in the Tabek Panjang highlands, District of Baso, Agam Regency and Pasar Usang lowland, district of Batang Anai, Pariaman Regency, West Sumatera. The results showed that banana plants infected by R. solanacearum Phylotype IV have a high diversity of flower-visiting insects. The diversity of insects in the lowlands is higher than that in highland and mainly are dominated by Trigona spp. (Hymenoptera: Apidae), Drosophila sp. (Diptera: Drosophilidae). To test the potential of both insect as vector of the blood diseases, isolated and identification of the bacteria using triphenyl tetrazolium medium chlorid (TTC) was used. Result showed that bacteria isolated from both insect are R. solanacearum hence providing evidence of the insect as vector of the blood diseases. Both insects have the potential to be vector of R. solanacearum Phylotype IV in West Sumatera. The identification of the bacteria that causes the disease. The identification of bacteria that is spread by flower visitors insects are R.solanacearum Phylotipe IV.

Teknik perbanyakan massal parasitoid Anagrus nilaparvatae (Pang et Wang) (Hymenoptera: Mymaridae) dengan kotak plastik Araz Meilin; Y. Andi Trisyono; Edhi Martono; Damayanti Buchori

Anagrus nilaparvatae (Pang et Wang) is an egg-parasitoid of rice brown planthopper (Nilaparvata lugens Stål). The objective of this study was to develop a mass-rearing technique of A. nilaparvatae. Mass-rearing was done using a plastic box (14 cm × 18.5 cm × 18.5 cm, made of plastic-mica, the upper side equipped with a 10 cm test tube), placed on a tray with rice seedlings containing an estimated of 11,130 eggs of N. lugens. About 355 adult parasitoids were successfully released per box when each box was infested with 50 parasitoids. The number of parasitoids produced were reduced to 164 adults when the infestation was made at 100 parasitoids per box. The emergence of parasitoids started around 07:00 am until 04:00 pm with the highest rate (36.2%) occured at 10:00 am. One plastic box cost only Rp10.000,-; thus the estimate cost to produce one parasitoid using this tecnique was Rp60,- These findings suggest that the plastik box is a simple and inexpensive technique for mass-rearing of A. nilaparvatae.

The objective of this research was to study the influence of host deprivation on the oviposition and physiological condition of Snellenius manilae Ashmead. The research was conducted at Laboratory of Bioecology of Parasitoid and Predator, Department of Plant Protection, Faculty of Agriculture, IPB. Ten parasitoids of the same age and cohort were used in this experiment. Deprivation of hosts were done for 1, 2, 3, 4, 5, 6 and 7 days at the beginning and toward the end of their life. All hosts were replaced every 24 hours. Result indicated that host deprivation affects the reproductive capacity of Snellenius manilae. Even though parasitoids were able to lay eggs even when they were deprived of hosts for seven consecutive days, the overall results of host deprivation experiment showed that the length and timing of deprivation period can affect reproductive capacity. Deprivation of hosts tends to increase the parasitism rate and the numbers of eggs laid upon their first encounter of hosts after the treatment. The difference is more pronounced on treatements that allowed parasitism to occur before the deprivation treatment. However, the overall results suggests that deprivation overall decrease the reproductive capacity of the parasitoid. The longevity of deprived individuals was also lengthened. Parasitoids that were given host before deprivation treatments tend to produced more eggs than those were not. These results showed that deprivation of hosts in the field may affect the effectiveness of parasitoids and the success of biological control.

Tanggap fungsional Menochilus sexmaculatus Fabricius (Coleoptera: Coccinellidae) terhadap Aphis gossypii (Glover) (Homoptera: Aphididae) pada umur tanaman cabai berbeda Novri Nelly; Trizelia Trizelia; Qorry Syuhadah

The lady beetle, Menochilus sexmaculatus is one of the biological control agents that can be used to control aphids. Presently, there is a lack of information about the effectiveness of this beetle to control aphids. The objective of this research was to study the functional response of M. sexmaculatus on Aphis gossypii at different ages of plants. All preys were exposed to one M. sexmaculatus adult for an hour at five different densities of aphids (10, 20, 30, 40, and 50 individuals) is four different ages of chilli plants (2,4,6, and 8 weeks). Data were analyzed by ANOVA and logistic regression to determine the type of functional response. The results showed that the ability of M. sexmaculatus to prey was not significant at 2 to 4 and 6 to 8 weeks old chilli plants. At 2 week old chilli plants M. sexmaculatus showed type I of functional response, while at 4, 6 and 8 weeks the functional response were type III.

In 2010 the pilot project of PJR program (routine larvae monitoring) was firstly implemented in Pedurungan village. The program was expected to increase community practice in mosquito eradication program (PSN-plus). The study was aimed to describe the difference of PSN-plus practice in pilot- and nonpilot- PJR villages. This was a comparative survey with cross sectional design. The study subject was household in pilot- and nonpilot-PJR villages which, consisted of 90 respondents each. The selection of study subject used proportional random sampling technique. To measure the of PSN-plus practice, questionnaire and observation sheet were used. Statistical analysis was performed with Chi-Square test. The result showed that PSN-plus practice in pilot village was better than nonpilot one. The statistical test proved the difference of bathtub drain (p value=0.006), closed water containers (p value=0.002), demolished used stuffs (p value=0.001), and hanging clothes habit (p value=0.0001).

The continous presence of dengue virus infection presents a serious health problem in many tropical areas of the world because of the severe and often fatal disease in children. Dengue viruses are transmitted to human through the biting of infected mosquitoes, especially Aedes aegypti and Aedes albopictus. This paper reported the nocturnal of biting activity of Ae. aegypti and Ae. albopictus in several areas of Indonesia. Natural population of Aedes was collected by bare leg collection and resting collection from 18:00 to 06:00 out door and indoor. The biting activities of Ae. aegypti and Ae. albopictus occurred throughout the night from 18:00 to 05:50 out door and indoor in Cikarawang, Babakan, and Cibanteng Kabupaten Bogor (2004); Cangkurawuk Darmaga Bogor (2005, 2007); Pramuka island, Pari island, Kepulauan Seribu (2008); Gunung Bugis, Gunung Karang, Gunung Utara Balikpapan (2009); and Kayangan, Lombok Utara (2009). These results showed that the biting activities of Ae. aegypti dan Ae. albopictus did not only occur diurnally but also nocturnally.
