Ornamental plants play an increasingly important role in urban habitats in Turkey. Scale insects are a serious pest group that attack ornamental plants. In this study, a total of 67 species of Coccoidea belonging to 7 families, which are harmful to ornamental plants, are given in Tables 1, 2, and 3. These tables are based on the authors data and on bibliographic sources. The most numerous families are Diaspididae (31), Coccidae (23), Pseudococcidae (7), Eriococcidae (3), and the Margarodidae, Kermesidae and Astereolecaniidae (1). Twenty-one of these species are harmful to flowering fruit and deciduous trees, 5 species are harmful to conifers, while 15 species are important orchard pests. Their hosts and distributions are also taken into consideration. 相似文献

The demand for a comprehensive protection of beneficial arthropods (parasites and predators) against pesticides has economical and ethical reasons. It is established in the plant protection law. An initial toxicity test on glassplates for the evaluation of side-effects pesticides have on the juveniles of the spider speciesCoelotes terrestris, living frequently in forest ecosystems, is presented. The test results with 22 pesticides are compared with those of an initial toxicity test made with the females of the hymenopteran speciesCoccygomimus turionellae. ForCoelotes terrestris five of the 10 investigated insecticides/acaricides are harmless after a time of three days on the treated glassplates, 3 are slightly harmful, 1 is moderately harmful and the last one is harmful. After a time of 6 days in the test cages only 4 of the 10 pesticides show a harmless action, 2 are slightly harmful, 1 is moderately harmful and 3 are harmful. All of the 5 fungicides, the 4 herbicides and 2 of the 3 growth regulators showed none or only a weak action. Only Prosevor 85 has to be named moderately harmful or harmful, depending on the time the juvenile spiders stayed in the test cages. For a normal test procedure with this spider species a test period of 6 days followed by a time of feeding control of 9 days is suggested. Five of the 10 insecticides/acaricides are harmless forCoccygomimus turionellae and the other 5 are harmful. Of the 5 fungicides four showed to be harmless and 1 moderately harmful. Three of the 4 examined herbicides are harmless too, whereas 1 acted moderately harmful. Two of the 3 growth regulators showed to be harmless, whereas the third one was harmful. The weight and size of the 2 test species in the investigated stadiums is nearly the same, so after a time of 6 or 8 days on the treated glassplates they show nearly the same reaction to the pesticides. The results and the significance of the tests with beneficial arthropods for the conventional and integrated plant protection are discussed. 相似文献

本文以四川汉源县核桃为对象,开展核桃病虫害调查,获得以下主要结果:汉源县核桃有害生物共计30种,其中危害较为严重的虫害为云斑天牛、木橑尺蠖、黄刺蛾、桃蛀螟、核桃举肢蛾等,病害普遍发生的是核桃炭疽病、核桃黑斑病、核桃缩叶病,具有潜在危害性的较大的是核桃木腐病、核桃枝枯病、核桃溃疡病和星天牛、茶丽天牛等对核桃枝干危害的有害生物。调查发现核桃有害生物种类随着温度的变化呈现周期性变化。汉源县4月气温10~30°C时虫害开始危害植株,病害也开始侵染植株,并随温度升高,种类增多,危害加重。11月气温10~20°C时有害生物危害降低,开始越冬。核桃有害生物种类以及危害程度与其种植环境有关。四旁树核桃、核桃和玉米混合种植有害生物危害较核桃纯林严重,核桃柑橘混合种植时有害生物种类较核桃纯林种类多,这可能与混栽植物间有共同有害生物有关,有关机理将进一步研究。 相似文献
