Abstract

Termite is one of the major pest on oil palm plantations, especially in peat soil. Application of synthetic insecticides will cause resistant insect, enviromental pollution, and other problems. The entomopathogenic fungus Metarhizium anisopliae has been reported to infect many insects, including termite. This study was aimed to analyze the effectiveness of treatment of M. anisopliae Cps.T.B and M. anisopliae Cps.T.B with zeolit in controlling termite, C. curvignathus. This research used a completely randomized design with three treatments and eight replications. The result showed that spore density of M. anisopliae Cps.T.B with zeolite was 2,5 x108 spores/g and M. anisopliae Cps.T.B without zeolite was 3,2 x108 spores/gram respectively. Germination ability of M. anisopliae Cps.T.B with zeolite was 91.11% and M. anisopliae Cps.T.B without zeolite was 87.41% respectively. Mortality of C. curvignathus on eight days after treatment using M. anisopliae Cps.T.B was 100% and using M. anisopliae Cps.T.B with zeolite was 95,5% while the mortality of C. curvignathus a control was 15%.

Abstract

Baung fish is one of fishery resources, which has significant economic potential in RiauProvince. Study on gut content can provide basic information that can be done topreserve the population of baung fish. A study on gut content of baung fish in SiakRiver of Rumbai Pesisir District, Riau Province has been carried out from July toNovember 2012 and from March to August 2013. The objective of this study was toknow about the diet composition on gut contents of baung fish such as main, suplement,and additional food. The method used in this study was The Index of Preponderance byNatarjan dan Jingran cit. Effendie (2002). The results of this study revealed that baungfish is categorized as a carnivore. The main food of baung fish was Rasbora sp(IP 34,2%), and additional foods were shrimp (IP 2,1%), Scutigera sp (IP 1,8 %), andGrynidae sp (IP 0,1%).

Abstract

Rana erythraea (Schlegel 1837) is a semi-aquatic amphibian that can be used as enviromental indicator. The environmental change will result in the occurrence of changes in the health condition of frog. This research on blood profile of frog was conducted to find out about the health condition of the frog living in the area campus of Riau University. The study was conducted from August to October 2013. Twenty frogs were captured (8 males and 12 females) and frog blood was sampled from the heart using a syringe that has been moistened with EDTA. Hematological parameters calculated were the level of haematocryte, leucocryte, the number of erythrocyte and leucocyte were 10-27%, 1.00-4.16%, 170.000-670.000 cells/ml3 and 1.875-3.666 cells/ml3 respectively.

Abstract

Termites is one of the major pest of oil palm plantations on peatlands. Termite control is generally performed using chemical insectisides. Several chemical insecticides can inhibit termite attack effectively but not effeciently used because it has many negative effects. The negative effect of chemical insecticides can be reduced using biological agents such as entomopathogenic fungus. This research aimed to determine the effectivenes and the best formulation of local isolate of M. anisopliae Cps.T.A and with the addition of 10% zeolite in controling C. curvignathus. The reaserch used Complete Randomized Design (CRD) with three treatments and eight replications. The results showed that density of M. anisopliae Cps.T.A with addition of 10% zeolite was 2,25 x 108 spora/g and M. anisopliae Cps.T.A was 2,50 x 108 spora/g. Germination of M. anisopliae Cps.T.A with 10% zeolite was 91,2% and M. anisopliae Cps.T.A was 88,1%. The treatment of M. anisopliae Cps.T.A produced the highest mortality (100%) of M. anisopliae Cps.T.A with 51% zeolite, whereas the mortality of termite control was only 16%.
