Effects of insecticidal sprays on poppy root weevils (Stenocarus ruficornis, Stephens 1831) were assessed in small plot trials at three localities in the Czech Republic during two years (2011&ndash;2012). In addition, the effects of seed dressing were included into the assessment in one of the localities (Červen&yacute; &Uacute;jezd). The levels of root damage caused by the insect pest larvae (expressed as number of bore holes per root) and yield got from individual treatments were compared. Sprays applied for 18 days after the first record of poppy root weevils in trials showed the highest effects on a decrease of the levels of root damage (40% of untreated control). In general, sprays applied at the date when SATF<sub>14</sub> value exceeded 20&deg;C showed significant effects on decreasing the levels of root damage. The highest effects were usually recorded in sprays which were applied when SATF<sub>14</sub> value exceeded 100&deg;C.

The first record of the seymouriamorph stem amniote Discosauriscus from the Krkonoše Piedmont Basin (the Czech Republic) is described. The specimen is identified as D. pulcherrimus on the basis of the following features which are absent in D. austriacus: 1) the pointed tip of the ventrolateral process of the postorbital lies anteriorly to the tip of the wedge-shaped dorsomedial process of the jugal; and 2) the rows of small denticles diverge anteromedially and anterolaterally from the midwidth of the ventral surface of the palatal ramus of the pterygoid. This new record increases our knowledge of the occurrence of this seymouriamorph in the Permo-Carboniferous basins of Europe.

Spray Treatment

In 2008 and 2009 the effects of quassin and neoquassin (oxygenated triterpenes) on apple sawfly (Hoplocampa testudinea Klug, 1814) were studied. In the Czech Republic, monitoring was carried out in small-plot trials and in one laboratory experiment. The extract containing quassin and neoquassin was made by boiling wood chips of a tropical shrub Quassia amara L. (Sapindales: Simaroubaceae). The experimental dosages were 3, 4.5, 6, and 9.25 kg of wood chips/ha. Spray treatment with the quassia extract was carried out just before most larvae hatched out. It was statistically proven that the extract from the wood of Q. amara reduced the apple sawfly infestation of fruitlets. Extract in the dosage corresponding to 3&ndash;4.5 kg of quassia wood chips for 1/ha appeared as optimal. The efficacy of these dosages was approximately 40&ndash;50%, and the efficacy above 80% was record.

The causal agent of the chestnut blight, the fungus Cryphonectria parasitica (Murrill) M. E. Barr (syn. Endothia parasitica (Murrill) P. J. Anderson et H. W. Anderson), was found out at new localities in the Czech Republic. The chestnut blight was observed for the first time in the Czech Republic in 2002. Two new localities were discovered in southern Moravia in May and June 2004. The disease was identified both on the sweet chestnut (Castanea sativa Mill.) and on the red oak (Quercus rubraL.). Infected trees were treated according to the order of the State Phytosanitary Administration of the Czech Republic.&nbsp;

A New Species

A new species of Mycetophilidae (Diptera), Acomopterella martinovskyi sp. n., is described from the Czech Republic and Austria. This is the first record of the genus from the Palaearctic region. Its relationships with other genera and variation in wing characters are briefly discussed. A new combination and synonymy is proposed: Acomopterella fallax (Sherman, 1921) comb.n. = Acomopterella arnaudi Zaitzev, 1989 syn.n.

Poppy (Papaver somniferum) is the traditional crop in the Czech Republic. The surveys of the appearance of some agents harmful to plants within the territory of the Czechoslovakia (Czech Republic) in 1961 – 2000 were used for elaboration of the set as given above. The particular agents are divided into four groups 1. The influence of drought (precipitation insufficiency, drought and influence of high temperature are involved in this group). 2. The influence of extraordinary heavy precipitation (there is hailstrom and other damage). 3. Damage caused by low temperature and frost 4.The influence of the harmful impact of wind weather (there are wind, erosion caused by wind and wind storm). The data, as above, testify the high sensitivity of the poppy to the course of climatic conditions. It has been confirmed that poppy is problematic crop.
