Adaptive Potential for the Invasion of Novel Host Plants in the Bean Weevil: Patterns of the Reproductive Behavior in Populations That Used Different Host Plants
The goal of this work was to examine interpopulation patterns in the reproductive behavior of populations of bean weevil (Acanthoscelides obtectus Say; Coleoptera: Bruchidae) that had different levels of specialization ... -
Determination of Copper-Based Fungicides by Flame Atomic Absorption Spectrometry Using Digestion Procedure with Sulfuric and Nitric Acid
Copper-based fungicides can be effectively digested by treatment with a mixture of concentrated sulfuric and nitric acid in exactly 15 minutes for the rapid determination via copper using flame atomic absorption spectrometry ... -
Methods of Imazethapyr Extraction from Soil and Cleaning up by Solid Phase Extraction
The aim of this work was to optimize the determination methods of imazethapyr residues in soil using HPLC with DAD and C 18 (Hypersil ODS, 5 ìm, 2.0 x 250 mm) columns and to find the most appropiate solvent for imazethapyr ... -
Effectiveness of Spirodiclofen in the Control of European Red Mite (Panonychus ulmi) on Apple and Pear Psylla (Cacopsylla pyri)
The effectiveness of spirodiclofen, an acaricide and insecticide with a novel mode of action, in protecting apple from the European red mite (Panonychus ulmi) and pear from pear psylla (Cacopsylla pyri) was tested in ... -
Determination of Resistance Levels of Myzus persicae (Sulzer) by Biochemical Methods
Peach/potato aphid Myzus persicae (Sulzer) has developed three mechanisms of resistance: overproduction of one or two closely related carboxylesterases (E4 and FE4), production of modified acetylcholinesterase (MACE and ... -
Uncinula necator (Schow) Burr., the Causal Agent of Grape Powdery Mildew: Role of Winter and Early Spring Treatments
Three preceding articles (Miladinoviæ et al., 2007a, 2007b, 2007c) covered the state-ofthe art on the pathogen and disease, the source of inoculum and pathogen infection potential, and the microclimatic conditions of ... -
Cacopsylla picta (costalis Flor, 1861) (Förster, 1848) (Homoptera, Psyllidae) a New Jumping Plant Louse Species on Apples in Serbia
Until recently only one jumping plant louse species Cacopsylla mali Schm. has been described on apples in domestic literature. Over the past few years investigations of Psylloidea on apples in Serbia have proved incidences ... -
Examination of Mutagenic Effects of GAL-57 Herbicide (Bentazone+Dicamba) Using Mouse Micronucleus Test
A micronucleus test was run to investigate mutagenic potential of the herbicide GAL-57, a formulated mixture of bentazone and dicamba. The test was applied to mice of both sexes (strain: CRL: NMRI BR) and the herbicide ... -
Biology and Harmfulness of Unaspis euonymi (Comstock) in the Area of Belgrade
Unaspis euonymi (Comstock) (Homoptera: Diaspididae) is a very dangerous pest of Euonymus spp. Numerous scale colonies and a high level of plant infestation provoke drying of leaves, branches and whole plants. As a result ... -
Efficacy of Rodent Control in Alfalfa and Wheat Crops Using Chemical and Natural Rodenticides
Biological efficacy of chemical and natural rodenticides in controlling rodents in alfalfa and wheat crops was investigated. The experiment was set up using a randomized block design with four replicates and 400 m2 plots ... -
Sensitivity of Cladobotryum spp., a Pathogen of the Button Mushroom (Agaricus bisporus), to Some Fungicides
Thirteen isolates of Cladobotryum spp., isolated from diseased fruiting bodies of Agaricus bisporus, sampled from mushroom farms in Serbia during 2003-2006, were studied. Sensitivity to several selected fungicides was ... -
Efficacy of Strobilurin-related and Multi-site Fungicide Mixtures Against Apple Scab
The efficacy of several fungicide mixtures in controlling Venturia inaequalis in apple was evaluated in field trials. The efficacies of Flint Plus (trifloxystrobin + captan) and Tercel (pyraclostrobin + dithianon) in ... -
Uncinula necator (Schow) Burr., the Causal Agent of Grape Powdery Mildew: Infection Potential and Microclimate
Microclimate in Podgorica vineyards and its effect on the formation, maturing and rupturing of cleistothecia, and disease outbreak, was studied. An analysis of collected data on minimum and maximum temperatures and ... -
Pesticides and Arthropods: Sublethal Effects and Demographic Toxicology
Insecticides and acaricides designed to control primary harmful insects and mites may also variously affect some other arthopods present in an (agro)ecosystem (e.g. secondary pests, predators, parasitoids, saprophytes, ... -
Headspace Solid Phase Microextraction in Pesticide Residues Analysis: 2. Apple Samples
Headspace solid phase microextraction method (HS/SPME), optimised previously for pesticide water solutions, was applied to trace residues of the pesticides chlorpyrifos, fenthion and bifenthrin in apple samples. One-hour ... -
Pome Fruit Viruses in Bosnia and Herzegovina
Field surveys and laboratory tests were carried out to assess the sanitary status of pome fruit trees in Bosnia and Herzegovina. Field surveys were carried out in 10 orchards, two nurseries and one varietal collectione ... -
Identification of Potato Virus Y Strains in Tobacco Crops
Five viruses: Potato Virus Y (PVY), Tomato Spotted Wilt Virus, Cucumber Mosaic Virus, Tobacco Mosaic Virus and Alfalfa Mosaic Virus, of which PVY was predominant, were detected by serological testing of tobacco samples ... -
Biological Traits of Botrytis cinerea Pers. Isolates Differently Sensitive to Dicarboximides
A study of biological characteristics of both field and laboratory isolates revealed that highly resistant isolates were morphologically different from their original wild types. The majority of them were less pathogenic ... -
