    Termites (Coptotermes curvignathus L.) is one of the important pests which attack crops, especially in oil palm plantations the newly opened planted on peat. Termites can cause physical damage directly up to 10.8%. During these to control this pest undertaken by farmers is the use of chemical pesticides that can cause damage to the environment and injuries the health of other living organism.Therefore need another tecknologi to control Captotermes curvignathus is the use of Jatropha curcas L which save for environment. This research used Completely Randomized Design (CRD) with 4 treatments and five replications. The treatments are without starch of Jatropha curcas on 50 gram of saw dust, 5 gram of starch of Jatropha curcas/50 gram of saw dust, 10 gram of starch of Jatropha curcas/50 gram of saw dust, 15 gram of starch of Jatropha curcas/50 gram of saw dust, 20 gram of starch of Jatropha curcas/50 gram of saw dust. Previous research has gained that Jatropha capable to control the Termites pest, so it needs to be done research to make concentration Effective and efficient in termite control. The results of research showed in concentration 5g/50g sawdust more effective in termite pest control , because concentration 5g/50g sawdust can causing value of mortality by 85%.

One of them is botanical insecticide with sweet flag rhizomes. This study aimed to obtain the right concentration of sweet flag rhizome extract (Acorus calamus L.) to control the pests of peach aphids M. persicae Sulzer in pepper plant. This research was conducted at the Laboratory of Plant Pest and Technical Implementation Unit (UPT) Experimental Farm Faculty of Agriculture, University of Riau for 3 months, from February to April 2012. This study has been conducted using a completely randomized design consisted of 6 treatments (some concentration of sweet flag rhizome extract) and 4 replications in order to obtain 24 experimental units. Each trial consisted of 30 individuals M. persicae Sulzer. Data obtained from the observations were statistically analyzed using analysis of variance, followed by Duncan's New Multiple Range Test (DNMRT). The results of some concentrations of sweet flag rhizome extracts (Acorus calamus L.) test towards the aphids M. persicae Sulzer showed that concentrations 50 g/l water of sweet flag rhizome extract (5%) is an appropriate concentration which is in the range of lethal concentration (LC) 95 that is 4,84-20,72% with total mortality 90,83%.

    Red pepper (Capsicum annum L.) constitute one of the important vegetable commercially to cultivated in the tropics and have high economic value. Cultivation of chilli in riau have continued increases very fast, but in production of chilli very decrease. One of causes production of chilli decrease is incursion from peach aphids (Myzus persicae) pest. which damage the plant by sucking the liquid in the plant tissue. Effort control this pest still to use synthetic chemical insecticides, but synthetic insecticides can cause negative effects such as pest resistance and pest resurgence. To remember impacts negative of use synthetic insecticides, so I have sought other method solution to control peach aphids pest with safe and effective. With application vegetable insecticides using the fruit betel forest (Piper aduncum L.). The fruit betel forest can to control peach aphids (Myzus persicae) on the chili of plant. This research was conducted at the Pest of Plant Laboratory Faculty Agriculture Riau University Campus Bina Widya in Pekanbaru that lasted for 3 month (February to may). The research was conducted using design random of completely (RAL) method with 5 handling and 5 repetition there SRH0 (without extract flour the fruit betel forest) SRH1 (with extract flour the fruit betel forest 25g/L of water) SRH2 (with extract flour the fruit betel forest 50g/L of water) SRH3 (extract flour the fruit betel forest 75g/L of water) SRH4 (with extract flour the fruit betel forest 100g/L of water). Concentration extract flour the fruit betel forest 75g/L of water is an appropriate concentration in controlling the aphid Myzus persicae pest with the percentage of total mortality by 90% and value LC95 amounted to 7.15%.
