Abstract

The objectives of this study were to determine the population density of A .craccivora and its dispersion on groundnut plant under different soil water availabitiles. the study was conducted in a greenhouse of Crop and Horticultural Plant Protection Institute Region III, Palembang since August to November 2001 using corrpletely randomized design with four levels of soil water availabilities and four replications. Each replication consisted of two plants, which were planted on different black, polyvinyl bag. The treatments were 40, 60, 80, and 100% soil water availabitiles The results showed that types of dispersion of A. craccivora on the whole part of groundnut planted on all soil water availabilities tested were similat n, each other. The population was found higher on young leave and bud leave, then followed on leaf stalk, f lower/gynophore, and stem respectively. The differences in the length of leaft trachoma , number of stem trichoma, and water content of leave and stem were the determinant factors, which influenced the population of A. craccivora on leave and stem in the maximum of population density.

Abstract

Fruit flies are major plant pest in guava. Research aimed at knowing theeffectiveness some trap types forward fruit flies pest at guava plant (Psidiumguajava L). Research is implemented by using a randomized block design (RBD)with 4 treatments and 16 groups, in order to obtain 64 units of the experiment. Thetreatment is on trial is this: a ball, a cube, a card, a cylinderl. The data analysisstatistically to a diverse and tested the real difference to the smallest (bnt).Parameter observed is, identification of the fruit flies trapped, the fruit fliestrapped, sum of fruit flies male, sum of fruit flies female and sex ratio fruit flies.The results show the fruit flies trapped in a furious ball 79,25 flies, which isobtained fruit flies trapped by using a cylinder that 78,25 flies.Keywords: Fruit flies, trap types, ball, cube, cards, a cylinder, Psidiumguajava L.

Abstract

Aphis craccivora Koch is a major pest in long beans. One of the alternative control can beused to minimize the application of chemical pesticides. One of to control pest of cropcan use tobacco extract. The research was conducted at the Plant Pests Laboratory,Faculty of Agriculture, University of Riau from March 2013 until May 2013. Theexperiment consist of two factors with three treatment and four replicated. The first factoris cigarette butts with a sticker: L1 = Rolled 1g/l of water, L2 = Rolled 1g/l of water andlerak, L3 = Rolled 1g/l of water and cream soap. The second factor is infestation days: H1= First day, H2 = Second day, H3 = Third day. The data is analyzed by using the Analysisof Variance (ANOVA) and Duncan’s New Multiple Range Test (DNMRT) at level 5%.The results showed that the better treatment is extract of tobacco cigarette roll butts 1 g/lof water and cream soap with the first day of the application because capable causingtotal mortality of 85%.Keywords: Aphis craccivora Koch, Long Beans (Vigna sinensis L), TobaccoExtract.

Abstract

Fruit fly (Diptera : Tephritidae) are a major pest of guava plants which cansiderably lowers the production of fruits, both in guantity and guality. This studyaims to determine the durability of some packaging materials that are used tocontrol fruit flies in guava plants. This research was conducted at the Center forAgricultural Development and the University of Riau and Laboratory Plant PestFaculty Agricultural, from April to June 2013. This research was carried out byusing a randomized block design (RBD) with 5 treatments and 4 replication thenewsprint, black carbon paper, black plastic bags, cement paper, transparentplastic. The results of the study showed that the use of packaging materials thathold and effectively protect the guava fruit from treated paper material is cementweighing 151.450 g fruit, and fruit morphology yellowish green color, soft textureshape of a round and 51 days durability.Keyword: Guava (Psidium guajava L.), fruit fly (Bactrocera spp.), andpacking material

Abstract

Aphis gossypii (Homoptera: Aphididae) is major pest in red pepper plant who may createdamage. This study aims to test amount row trap plant in order to control attack leaf bug Aphisgossypii Glover (Homoptera: Aphididae) at red pepper plants (Capsicum annum L.). Thisresearch was conducted at the Technical Organizer Unit Trial Garden and Laboratory Plant PestFaculty Agricultural University of Riau, from June to August 2013. This research was carriedout by using a randomized block design (RBD) with 5 treatments and 4 replication withoutplanting trap plant, 2 rows red pepper 1 row mustard, 1 row red pepper 2 rows mustard, 1 rowred pepper 3 rows mustard, 2 rows red pepper 2 rows mustard. The results of the study showedthat planting 2 rows red pepper 2 rows mustard is better because leaf bug trapped too much fromtreatment else with average 22,87 tails in red pepper and 23,06 tails in mustard. Every reductionof populations one tail leaf bug in red pepper, then populations of leaf bug in mustard to go up0,763 %.Keyword: Red pepper (Capsicum annum L.), Aphis gossypii Glover, and mustard (Brassicajuncea L.)
