Budidaya tanaman buah naga mulai berkembang di Indonesia sejak tahun 2003. Hingga saat ini, penyerbukan di kebanyakan perkebunan masih dilakukan secara buatan. Perbedaan perilaku serangga menjadi hal penting yang dapat menentukan kesuksesan penyerbukan alami. Keberadaan serangga lokal diduga dapat menjadi agen polinator yang dapat mengurangi aktivitas penyerbukan buatan pada bunga buah naga. Penelitian ini dilakukan untuk mengetahui karakteristik perilaku serangga yang berpotensi menjadi agen penyerbuk alami buah naga. Kata kunci: perilaku, serangga, Hylocereus undatus

Pada tahun 1998, kecamatan Cineam di kabupaten Tasikmalaya, Jawa Barat, mengalami Kejadian Luar Biasa (KLB) malaria dengan jumlah kasus mencapai 800 kasus sehingga Pusat Kesehatan Masyarakat (PUSKESMAS) kecamatan Cineam berada pada stratifikasi High Case Incidence (HCI). Kondisi berbeda terjadi pada tahun 2009 dan 2010 dimana jumlah kasus yang terjadi adalah 15 dan 6 kasus, secara berurutan. Penelitian ini bertujuan untuk melakukan analisis terhadap faktor-faktor yang menyebabkan KLB malaria tahun 1998. Metoda pengambilan data dengan (1) pencuplikan nyamuk Anopheles menggunakan CO2 Trap di 5 dari 10 desa pada kecamatan Cineam untuk mengetahui populasi nisbi dari nyamuk vektor malaria dan (2) wawancara dengan petugas pemberantasan penyakit menular (P2M) yang bertugas pada PUSKESMAS kecamatan Cineam saat KLB pada tahun 1998. Hasil yang diperoleh pada penelitian ini, dari 320 individu nyamuk Anopheles yang ditangkap, terdapat empat jenis nyamuk Anopheles dengan tingkat dominansi, Anopheles vagus (33,13%), Anopheles aconitus (28,75%), Anopheles barbirostris (23,75%), dan Anopheles kochi (14,38%) dimana hanya An. aconitus dan An. barbirostris yang merupakan vektor malaria. Keberadaan nyamuk Anopheles ini didukung oleh faktor klimat serta keadaan lingkungan setempat yang menyediakan feeding place, resting place, dan breeding site bagi nyamuk Anopheles. Walaupun demikian, keberadaan populasi nyamuk Anopheles bukan merupakan faktor utama penyebab KLB malaria, melainkan rendahnya pemahaman masyarakat pada penyakit ini. Hal ini ditunjukkan oleh rendahnya tingkat prevalensi malaria yang sangat rendah (Low Case Incidence) yaitu pada tahun 2009 dan 2010 (sebesar 0,44‰ dan 0,18‰ secara berurutan) setelah dilakukan penanggulangan penyebaran malaria dalam bentuk penyuluhan pada warga sejak KLB pada tahun 1998.

Black soldier fly (Hermetia illucens) is one of the biological agents for organic waste decomposition. This process produced insect biomass with significant economic value. To maintain the population of this insect, an artificial rearing had to be done to produce a continuous supply of eggs. One of the important components of egg production is substrate to attract female to lay egg on the ovitraps. Ovitrap is a structure applied to accumulate the egg for easier handling. In this study, the preference of female on the several types of attractants was tested. The subtrates were rotten cabbage, rotten papaya, tofu dreg, and commercial fish feed. The preference was based on the amounts of eggs laid on the ovitrap (in weight). The result showed that fish mill is the most preference substrate (amount of eggs: 2.17 gram) while tofu dreg was the least preferred substrate (amount of eggs: 0.06 gram).

Publisher : Universitas Gadjah Mada

Research on the effect of B. thuringiensis sublethal infection to the chance of H. armigera to resurgence has been conducted. Third instar insects were used and the concentration applied were 0 ppm, 150 ppm, 300 ppm, 450 ppm and 600 ppm. The result showed that along with the increase of B. thuringiensis infection, the number and the viability of the eggs production declined. In addition, the weight difference between the 3rd and the 4th instar became higher however between the 4th and the 5th became lower, moreover, the weight of female imago decreased, the life longevity of male and female imago were shorter and longer, respectively, along with the increase of B. thuringiensis infection. The possibility for resurgence will be discussed.

This study aimed to determine the efficiency of the use of propolis as a biocoating for post-harvest bananas in order to extend shelf life. This study used local banana that typical in Indonesia, Moss banana (Musa acuminata) and the propolis bee Trigona laeviceps, which is also produced by local agriculture, with a concentration of application 5%, 10%, 15%, coating using 70% ethanol as a positive control, and bananas without coating as a negative control. Observation parameters that measured are weight loss, pulp to peel ratio, size, color, fruit temperature, cell death, fruit firmness, total soluble solid (TSS), sucrose content, vitamin C, and potassium content on days 0, 3, 6, 9, 12, 15, 18 and 21 after coating. The results showed that coating using 5% propolis significantly extend the shelf life compared to the control by slowing the increase in fruit maturity index (color), weight loss, size loss, pulp to peel ratio, fruit temperature, pulp softening, and increased levels of vitamin C. Treatment process itself does not have a significant effect on changes in the value of TSS and sucrose during the storage period.Keywords: propolis, moss banana, post-harvest protection.

Studies showed that cross-pollination also affect fruits and green bean coffee quantity and quality yet study on this subject in Indonesia rarely found. This study focused on assessing the pollination effect of fruit quality and beans in terms of size, weight, physical defect, and content of caffeine and fatty acid. During this study, Tetragonula laeviceps, indigenous stingless bees, were applied as a pollination agent to be compared to open pollination. The result showed that open pollination produced bigger beans (16.73abÂ±1.57 X 14.66aÂ±1.48 mm) with higher caffeine (18.22%) and lower fatty acid (41,86%), while application of T. laeviceps produced slightly heavier beans (0.22 gram). Besides producing higher caffeine and lower fatty acid, cross-pollination services mainly required wild pollinators, although T. laeviceps could act as a potential replacement or for the inundation of this service.

Hyperglycemia has been proven to increase oxidative stress due to the production of reactive oxygen species (ROS) that exceed the capabilities of the natural antioxidant defenses, causing a deficiency in insulin receptors and insulin resistance. In this study, the effect of propolis on ROS was observed. Fifty five (55) male mice (Mus musculus SW.) were divided into 5 groups, i.e. KN (normal control), KDM (diabetes control), and P1, P2, P3. Propolis solution 50, 100 and 175 mg/kg bw was given to groups P1, P2 and P3 respectively, while distilled water was given to groups KN and KDM by oral gavage for 21 days. Density of ROS was measured every 7 days, while measurement of plasma insulin was carried out every 3 days. The results show that the density of ROS in the groups treated with propolis was lower than in the KDM group. However, the plasma insulin levels in the propolis groups were higher than in the KDM group. It was concluded that propolis can decrease ROS density and causes an increase in plasma insulin levels.

Pertumbuhan dan perkembangan larva Musca domestica Linnaeus (Diptera: Muscidae) dalam beberapa jenis kotoran ternak Ramadhani Eka Putra; Abdul Rosyad; Ida Kinasih

House fly (Musca domestica) is an important urban insect that can transmit various infectious diseases. This insect usually utilized organic wastes as nutrition source for their larvae. One of the main sources of organic wastes is livestock manure produced by animal farming located near human dwelling area. Thus, appropriate house fly population control program at animal farm is needed,based on information on the house fly’s life history. The research is focused on the development of house fly larvae reared with different livestock manures, such as cow, chicken, and horse. As comparison, rice bran were used as control. Results showed that larvae reared with horse manure has the shortest development time (5 days), with lowest larval survival rate (30%), pupal weight (6.8 ± 0.141 g), and weight of female imago (4.9 ± 0.14 g). This finding indicates the lowest nutrition value of horse manure for house flies larvae. Further research is needed to find the effect of manure to variables that directly influence population growth, such as fecundity of female flies and egg survivorship. These additional information on life history will help the design of appropriate house fly population management program for animal farm.

In this study, termite bait comprising pinewood of sawdust and a slow action insecticide, fipronil, was made and applied to control subterranean termite Macrotermes gilvus (Hagen) (Isoptera: Termitidae) in Bandung. Colony size was measured using capture-mark-release-recapture prior to the bait application, along with the measurement of wood consumption at each station. Colony foraging populations at all stations were estimated to be 77,951 termites, with mean wood consumption rates ranging from 0.02 to 6.16 g/station/day. Observation at 18 stations installed with bait consisted of 40 ppm fipronil mixed with pinewood sawdust showed that number of foraging activity termites was effectively reduced in 40 days. It is concluded that fipronil-treated pinewood sawdust bait is effective in controlling the population of foraging M. gilvus workers in 40 days.
