    Opis:
    Extensive studies have been carried out to identify plant phenolics with insecticidal properties towards insects. The subject of the study were comparison of control and infested by Acyrthosiphon pisum (Harris) vegetative parts of pea plants. In the pea plants six flavonol aglycones were identified: quercetin, kaempferol+RCO-, kaempferol, tricin, apigenin+RCO-, and apigenin. In infested plants relatively high concentration of total phenols, o-dihydroxyphenols and total flavonoids in comparison with control were observed. It suggests that phenolics have negative effect on insects and they are good for control of the insect pests.

    Opis:
    The paper presents some aspects of relations between modern plant protection of apple orchards and ecotoxicology. Based on significant similarity of the shape and size of apple and tomato fruits the relation between the doses of active ingredients of plant protection products and their residue levels immediately after treatment was derived for the apples and then quality indices and the risks for human health were estimated. It was found that many of the currently in force MRLs need to be revised and the exposure of consumer should not exceed the acceptable daily intakes (ADIs) and acute reference doses (ARfDs) for pesticide residues.

    Opis:
    The objectives of this work were to describe the residual behaviour of chlorpyrifos (insecticide) and chlorothalonil (fungicide), applied for the protection of carrot and parsley plantations. The field tests were carried out at farms located near Rzeszów (South-Eastern Poland) on processing carrot and parsley destined for baby food production. The results obtained indicated that disappearance rate of chlorothalonil on carrot leaves was significantly faster and its half-life time was about 7 times shorter than that of chlorpyrifos. In weather conditions of 2006, chlorpyrifos residues in rape carrot and parsley roots were reduced to levels lower than MRL and even the rigorous value of 0.01 mg/kg.

    Opis:
    Efforts have been made during the past three decades to develop insecticides with selective properties that act specifically on biochemical sites present in a particular insect group, but whose properties differ from those present in mammals. This approach has led to the discovery of compounds that affect the hormonal regulation of molting and developmental processes in insects such as ecdysone agonists, juvenile hormone (JH) mimics and chitin synthesis inhibitors. The search for potent acylureas has led to the development of novaluron (Rimon) developed by Makhteshim Chemical Works. The LC-50 value of novaluron on 3rd-instar Spodoptera littoralis fed on treated leaves is approximately 0.1 mg a.i./liter. This value resembles that of chlorfluazuron and is tenfold lower than that of teflubenzuron. Novaluron affects nymphs of Bemisia tabaci more than chlorfluazuron and teflubenzuron. Artificial rain, at a rate of 40 mm/h applied 5 and 24 h after treatment in a cotton field had no appreciable effect on the potency of novaluron on both S. littoralis larvae and B. tabaci nymphs. Hence, novaluron can be used in tropical areas and during rainy seasons. In general, benzoylphenyl ureas had no direct effect on parasitoids and phytoseiids and are considered mildly affect other natural enemies. Novaluron has no cross-resistance with conventional insecticides, the JH mimics pyriproxyfen and neonicotinoids. As such, it is considered an important compound in pest management programs.
