Termites are the major agent in wood biodeterioration, particularly in building materials, thus its existence in wood become trouble. Chemical insecticides are widely used to prevent the lost from termites attack. The use of chemical insecticides, however, do not recomended as it may cause risk to human health, environment, and may also harm to the non-target organisms and lead to the development of pest resistance. For that reason, these situations encourage many scientists to develop and evaluate various prospective biological control of termites. One of them is utilization of entomopathogenic fungi to suppress termite population.The object of this research is learning pathogenic ability of Cunninghamella sp. (habitually found around termites nests) in termite’s mortality. The methods of this research are fungal isolation and then pathogenic test to termites (termite’s infection). The ways of termite infection are contact and digestion. The best method is based on termite’s mortality rate after infection.The results show that Cunninghamella sp. causes termites mortality significantly than control. The higher mortality rate of termites is shown by contact infection method than digestion infection method. It might indicate that contact infection method more effective to suppress termite’s population

Fungal spore can be used for biotermiticide, since it has high pathogen properties and environmentally safe. However, the utilization of enzyme extract of fungi can be developed as an alternative way to minimize the impact caused by the spore when they are used as biotermiticide. This research was done to observe the ability of enzyme extract from Humicola sp. The fungus was inoculated in sorghum substrate and grown in it by adding either colloidal chitin or without colloidal chitin to the media as variation of the medium composition. Extraction was done after 3, 5, and 7 days of incubation time. Extract was done by using cold sterilized water (40C). Then the extract kept it at low temperature (40C). Bioassay of extract enzyme was done by spraying and baiting method. Result of the bioassay showed, Humicola sp enzyme extract was grown from medium adding with colloidal chitin and incubation for 7 days give highest mortality of termite increase to 100% after 14th day observation.

Subterranean termite especially Coptotermes sp has been spread widely and has caused a tremendous economical loss. Various chemical compounds have been used to overcome termite attack. However, utilization of chemical could endanger the environment, thus it is important to find another compound which can be used as an environmental friendly wood preservatives. One of the alternatives is to extract natural compound which has an anti-insect peculiarity. Fruits, leaves and barks of Bintaro and Kecubung, especially their leaves and flowers have been widely known as traditional medicine. This paper explains the effects of the extracts of Bintaro (leaves and bark) and Kecubung (leaves) on subterranean termite of Coptotermes sp.Leaves and bark powder of Bintaro and leaves powder of Kecubung were extracted with n-hexane, ethyl acetate, acetone, and methanol. Paper disc which has been dropped by the extract solution was used as bait to subterranean termite of Coptotermes sp. The observation of termite mortality was calculated for every two days during 10 days of observation. The result shows that Bintaro leaves extracted with methanol caused 100% termite mortality on last observation. Whereas on Bintaro bark extracted with n-hexane and acetone caused 100% termite mortality on eighth day of the treatment. Kecubung leaves extracted with n-hexane and ethyl acetate caused 100% termite mortality on last observation

Utilization of fungal entomopathogen as biological control agent has been developed in several country, but not in Indonesia. Therefore, the use of biological control agent to control termite need to be done in order that diminish chemical insecticide hazard. In this research, the ability of fungal entomopathogen (Hyphomycetes) identified as Metarhizium anisopliae, Beauveria sp. and Humicola sp. to infect Subterranean termite will be evaluated. The fungi were isolated from Indonesia. The research methods are (i) to sporulate fungi in rice culture media; (ii) to formulate fungal entomopathogen being infection materials; (iii) bioassay of fungal entomopathogen against Subterranean termite by contact method. The result of bioassay show that the three fungi (Humicola, M. anisopliae and Beauveria) are able to kill termite in 14 days of observation day. Primarily, M. anisopliae has generate termite’s mortality almost similar to Humicola sp. i.e higher than 60 %, in other side Beauveria just affect termite’s mortality lower than 60 %.

It was informed that the fruit extract of Cerbera manghas has antitermic and bio-larvicidal activities. The objective of this research is to study the effect of Cebera manghas fruit extracts on the mortality of Sitophilus oryzae (Coleoptera: Curculionidae). Dried sample of C. manghas fruit was milled and then extracted with maceration method using methanol. Crude extract was then dried and fractioned into 2 fractions i.e. n-Hexane and ethyl acetate. Three concentration of extracts (i.e. 3, 5, and 7.5%) were applied for bioassay test in the difference baited time (i.e. 30 min, 1 h, and 3 h). The results indicated that n-hexane fraction of C. manghas fruit extract was the most active fraction and it was indicated by the highest mortality of S. oryzae at all concentration. The longer the baited time resulted the higher the mortality of S. oryzae.Key words: bio-assay, Cerbera manghas, extractive, insecticide activity, Sitophilus oryzae

Selama dalam masa penyimpanan, komoditi hasil panen dapat mengalami kerusakan dan susut bobot (losses) yang disebabkan oleh serangan hama. Sitophilus oryzae adalah salah satu penyebab kerugian dan kerusakan terbesar karena memiliki kemampuan cepat berkembang biak akibat suplai makanan yang melimpah, mampu berpindah bersama-sama dengan komoditas hasil panen, serta mempunyai daya adaptasi pada kondisi kering. Pengendalian secara kimiawi tidak menjadi solusi, karena masih menggunakan bahan-bahan pestisida berbahaya seperti Carbamat, Piretroid, PH3 dan Metil Bromida,yang memiliki efek karsinogenik yang memicu kanker, akibat efek residual yang tertinggal dalam komoditas pangan. Berdasarkan hal tersebut, penelitian ini menawarkan teknologi pengendalian hama gudang penyimpanan hasil panen, menggunakan pestisida alami berbasis nimba, Azadirachta indica yang efektif, aman sekaligus ramah lingkungan. Hasil bioassay menunjukkan respon yang sangat baik, dimana mortalitas 100 persen S. orizae dicapai pada konsentrasi 10 ppm produk formulasi. Uji toksisitas akut oral dan dermal juga menunjukkan produk formulasi termasuk kategori bahan tidak berbahaya (WHO, 2003).During storage, stored product commodities could be damaged and lose weight caused by pest attack. Sitophilus oryzae is one of the most dangerous stored pests because of their fast reproductive abilities due to abundant supply of foods; their moving abilities with stored commodities; and their adaptability to extremely drying condition.Chemical treatments are not solving the problems because they still contain some toxical substances like carbamate, pyretroid, methyl boric, that would lead to residual contain remains on food commodity and possess carsinogenic effect Based on that background, this research proposes new stored product pest control technology using effective and environmentally friendly biopesticide based on neem (Azadirachta indica A. Juss). Bioassay results against S. oryzae show that 100 percent mortality is achieved at 10 ppm biopesticide formulation. Both acute oral and dermal toxicity tests also show that biopesticide formulation is classified as not harmful substances (WHO, 2003).

Currently, the availability of red meranti, kulim and mersawa wood is commonly used as raw material for “jalur” constructionin Kuansing Regency, Riau Province, are increasingly scarce, while the need is getting higher. Accordingly, it is necessary to choosealternative wood types that have similar strength and durable properties compatible with red meranti, kulim and mersawa wood tomeet specifications for the “jalur” construction. This paper studies the effectiveness of preservative treatment by infusion techniqueand bandage use against dry wood termite. Balam (Macaranga conifera Muell. Agr.) was chosen as alternative wood for makingthe path because currently this wood is abundant but not much used for making pathways. The results of field observations indicatedry-wood termites attacke the path stored on land, so it is necessary to preserve the path so that they are not attacked by wooddestroying organisms, particularly the dry-wood termites. Preservation treatments on standing trees using complex boron compoundsby infusion and bandage techniques were examined to increase the durability class of balam wood. Testing of dry-wood termiteattack was carried out according to the SNI 7207-2014 method. The data were processed using a completely randomized factorialdesign. The analysis results showed that the preservation by infusion and bandage techniques was significantly different in terms ofweight reduction and mortality of termites. Observation on the degree of attack visually on the control and infusion technique was40 (hold) lower than the bandage technique 70 (moderate). The highest mortality in infusion technique was 90.67% compared tocontrol 86.08%, and the bandage was 61.75%. Preservation using the infusion technique showed a higher boron content comparedwith the bandage technique.
