Abstract

Until now, cavities (caries) is still a dental and oral health problem that requires the attention of health workers. In some countries, the prevalence of dental disease has been reported to have declined, but from Riskesdas data the prevalence in Indonesia is still quite high at 72.86%. The WHO Global Oral Health Program (GOHP) advises countries in the world to develop policies for the prevention of dental and oral diseases and the promotion of dental and oral health. especially for school children and teenagers. One form of effort undertaken is to carry out a Fluorine rinse program in the Taman Siswa village of the Embassy of Silau Village by empowering Posyandu cadres to become dental health cadres. It is expected that this program can increase public awareness, especially the school community, to maintain oral and dental health so that optimal oral and dental health can be achieved for school children.

Abstract

AbstractMorphological and Molecular of Identification Bactrocera sp. (Diptera: Tephritidae) in 5 Location of Red Guava Crops District Deli Serdang. Fruit flies are a concern in the world because they are an important pest in fruits. Seven species of fruit flies (Bactrocera carambolae, Bactrocera papayae, Bactrocera curcubitae, Bactrocera caudata, Bactrocera albistrigata, Bactrocera tau, Bactrocera umbrosa) have been identified from the morphological identification of fruit flies in LIPI. The fruit fly is obtained from trapping with methyl eugenol, cocoa waste processing, and a mixture of both. Found 2 species of parasitoid (Psytallia sp. near Walker; Psytallia sp. near Walkeri) from the rearing of fruit that was attacked at five locations of red guava plantation district Deli Serdang.Keywords : Bactrocera spp., morphology, atractant, parasitoid

Abstract

AbstractMetarhizium anisopliae is an important entomopathogenic fungus that mainly used for biological control. Isolates of M. anisopliae extracted from soil from 15 oil palm plantations located in several districts on the Province of North Sumatra, Indonesia have been investigated to identify their morphological diversity. The morphology of assessed fungi was constructed in the the form of conidia, conidia size, color and shape colony and growth diameter of the 15 isolates. All of conidia forms showed cylindrical shape and string together. The length/width (μm) ratio of conidia size was minimum 2,16 and maximum 3,54. The highest growth rate isolates were found in M3 (Bandar Selamat) and M12 (Mancang) treatment and the lowest rate was M11 (Teluk Parit Kaca) treatment. The color of colonies were varied among the isolates. They were greenish yellow, dark green, yellowish and showing zonation/no zonation.Keywords : Metarhizium anisopliae, biological character, morphological diversity

Abstract

The Myopopone castanea Smith (Hymenoptera: Formicidae) is a predator of Oryctes rhinoceros Linn larvae, the main pest on oil palm plantations.  These predatory ants have potential as biological agents because they have similar niches to their prey. This research aimed to explore the presence and potential of M. castanea as bio-agents in oil palm plantations and obtain knowledge about the abiotic environment of Myopopone castanea ant nests. The research was conducted in oil palm plantations owned by PTPN 4 Adolina, PTPN 2 Pagar Merbau, and smallholder oil palm plantations in Binjai, North Sumatra Province.  Sampling was conducted using the purposive sampling method and as many as 10 sample points in each plantation. The results showed that the average temperature and humidity in the ant nests were 29.4 °C and 70.5%, respectively. The number of individual ants in a colony varied greatly in number and developmental stages. The predation potential of Myopopone castanea ants in the field reached 50.3% for five days of exposure in smallholder plantations and 46,9% in Adolina Plantation. This research could be the opportunity to use Myopopone castanea ants as a biological control for larvae Oryctes rhinoceros in oil palm plantations.
