Abstract

Guava (Psidium guajava L.) is a tropical plant that comes from southern Mexico and Central America. The rising demand of guava in Indonesia encourages the cultivation of guava which systematically with considerable high economic value. Decreasing productivity of guava currently caused by the attack of fruit flies. Therefore, it is necessary to conduct a research on trapping at several heights. This study uses a randomized block design (RAK) with a height of 0.5 m, 1.5 m and 2.5 m. The results have shown that the effective control of the pest trap fruit flies in the area of guava plant height of 1.5 m is the number of fruit flies were trapped as much as 59.25 flies, the number of male fruit flies were trapped 22.50 flies, female flies were trapped 36, 75 flies and the sex ratio comparison is 1: 1,7. Keywords: Fruit flies, Trap height level, Guava plants.

Abstract

Green stink bugNezara viridula L. (Hemiptera: Pentatomidae) is one of the important pest on long beans plant.One alternative that can be used to minimize the application of chemical pesticides is an extract powder from the babadotan leaf (Ageratum conyzoides L.). This research is purpose  to get the better concentration of a babadotan’s leaf powder extract (Ageratum conyzoides L.) for controllinggreen stink bug Nezara viridula L. at long beans plant. This research was conducted at the Center for Agricultural Development and Plant Pests Laboratory Faculty of Agriculture, University of Riau from April to June 2015. This research was carried out experimentally by using completely randomized design (CRD) with 5 treatments and 4 replications.Treatment consists of several concentrations of  babadotan’s leaf powder extract 75 g/l of water, the concentration of 85 g/l of water, the concentration of 90 g/l of water, the concentration of 95 g/l of water, the concentration of 100 g/l of water. The parameters observed were the initial time of death (hours), lethal time 50 (hours), daily mortality (%),total mortality (%), lethal concentration 50 and 95 (LC50 and LC95) (%), temperature and humidity as supporting observations. The results showed that the concentration of  100 g/l of water caused total mortality 72,50%, this has not yet reached a good concentration in the control of green stink bug because not being able to control the green stink bug over 80%, while the value of LC95 obtained is greater than 10%, it is16,8% or equivalent to 168 g/l of water.   Keyword:Long bean (Vigna sinensis L.), Babadotan (Ageratum conyzoides L.), Green stink bug(Nezara viridula L.).

Abstract

The purpose of this study was to determine the dose of flour forest fruit betel (Piper aduncum L) that best powder beetle kills pests (Sitophilus zeamais M) on corn in storage. This research was conducted at the Laboratory of Plant Pests, Faculty of Agriculture, University of Riau, Pekanbaru. The study was conducted from April to June 2016. The research method implemented experimentally. This research was conducted in two series, the first carried out for 72 hours to observe the initial time of death, the daily mortality, Lethal time50, and total mortality, and the second after 5 weeks of infestation, which is observed is S. zeamais beetle population growth and shrinkage weight of corn by pests S. zeamais, using a completely randomized design (CRD), which consists of six treatments, with four replications thus obtained 24 experimental units. Each experimental unit infested as many as 10 animals         S. zeamais. The results showed that the dosage of flour betel vine forest at a dose of 8 g / 100 g of corn is the best dose to control S. zeamais with total mortality of 97.50%, the initial time of 5.50 hours of death, lethal time50 (LT50) during 21:00 hours. Keywords: S. zeamais M, betel fruit woods, corn

Abstract

The use of synthetic pesticide give many negative impacts, therefore need to do the right control with microorganism utilize. That potentially microorganism such as entomopathogenic nematode. The research aims to isolate and obtain the entomopathogenic nematode isolat from the annual crops field at Agriculture Experimen Station in Faculty of Agriculture Riau University by using bait larvae of Tenebrio molitor. The research was carried out with survey methode. The sample were isolated from mustard greens field, papaya field and corn field at Agriculture Experimen Station. Data obtained were descriptive statistically analyzed and displayed in the form of picture. The results showed that isolation by using larvae of T. molitor had entomopathogenic nematode with the characteristics larvae of T. molitor which infected by entomopathogenic nematode were discharge of movement activity, motionless and finally the larvae was die with the change of skin colour from light brown to caramel. Another symptom was seen is larvae body became flabby, although that body shape still whole. The larvae colour change from light brown to caramel showed that larvae was infected by Steinernematidae family of entomopathogenic nematode. Steinernematidae family of entomopathogenic nematode had general and particural morphological characteristic. They had smooth head and not realated, pointed short tail, the vulva are jutting out and is located in the middle, nerves ring in anterior. The particular characteristic of Steinernematidae was they had no bursa at tail part. Keywords : isolation, identification, entomopathogenic nematode, Tenebrio molitor
