    Box tree moth shows (Cydalima perspectalis) rapid spread in Europe. In Hungary it appeared first near to the western border of the country in 2011. In the eastern part of Hungary the first specimen was caught in 2015 with blacklight trap. Here we summarize its distribution in northern part of the Alföld (Great Hungarian Plain) on the basis of blacklight, pheromone and feeding attractant traps. We publish five new distribution data from northern part (4 from Hungary, 1 from Transcarpathia) and two from southern part of the Alföld. Beyond that the flight of three generations was observed both in the year 2015 and 2016.

  • Monitoring raspberry cane midge (Resseliella theobaldi) on the basis of temperature data

    The ’midge blight’, in which the raspberry cane midge (Resseliella theobaldi) has an important role, is the greatest problem in the raspberry protection. The basis of the chemical protection against raspberry cane midge is the prediction of adult midge emergence. Before the application of sex pheromone traps developed for the investigation of flight pattern, the usage of the accumulated temperature was attempted for the prediction of egg laying, but these temperatures are different in each country. The aim of this paper is to give information on the time of raspberry cane midge emergence and flight pattern by using sex pheromone traps and accumulated temperature calculation.

  • The occurrence and phenology of moth pests in different granary of Borsod-Abaúj-Zemplén County

    The aims of my studies were the followings: primarily to find correlation between the conditions of granary and the occurrence of moth pests. Secondly I studied the effect of disinfection on individual numbers in the population of moths. My studies were started in May 2009 in six different places of Borsod-Abaúj-Zemplén County. Indianmeal moth (Plodia interpunctella) and Mediterranean Flour Moth (Ephestia kuehniella) traps with pheromone were installed in four repetitions as well as Angoumois Grain Moth (Sitotroga cerealella) traps in also four repetitions. Control traps without attractant were also placed at every place.
    From my researches, it became clear that the disinfection alone is not enough to protect cereals from moths. As in the case of crop protection, we need to apply integrated pest management.
    We have to make differences between preventive protections from moth pests and the elimination of them by chemicals.
    Up to my opinion, the regular checking and cleaning of the granary are important as well as the prognosis of the possible occurrence of moths. The prognosis is considered important because the studied moths do not feed at the adult stage or only at a low level. However, the caterpillars coming from the eggs placed by females can cause a significant damage in the stored cereals.
    The studied sex pheromone traps are proved to be useful for the reduction of number of moths since the traps caught lots of them. These traps are relatively cheap because only the temporarily changes of pheromones increase the cost.

  • Study on distribution and relative abundance of click beetle pests (Elateridae: Agriotes sp.) in Hungarian maize fields

    Click beetle pests (Elateridae: Agriotes sp.) of 24 sites in different regions of Hungary were studied in 2011. A. brevis, A. sputator, A.
    obscurus, A. lineatus, A. rufipalpis and A. ustulatus were sampled by pheromone traps in maize fields. During the study 65895 beetles were
    caught. A. ustulatus and A. sputator were the most abundant species. Beyond that 23 additional species were trapped so the total number of sampled species was 29. The distribution of the six studied species was uneven. In east Hungary A. ustulatus were the most abundant, while
    in the Transdanubia A. sputator was dominant in the most studied sites. A. obscurus occurred mostly in Transdanubia (western Hungary), and it occurred only in one site of eastern Hungary. 
    The abundance of one or simultaneously two species reached the threshold of significant damage in 14 sites. Additionally there were three sites where the total abundance of the two most dominant species reached the threshold. There were only six sites where we should not expect significant damage. In this reason we have to monitor the populations of these pests and if it is necessary we have to take actions against them.

  • Distribution and relative abundance of the economically important click beetles (Elateridae: Agriotes sp.) in Hungary

    Click beetle (Elateridae: Agriotes sp.) species of 24 sites in different regions of Hungary were studied in 2010. A. brevis, A. sputator, A. obscurus, A. lineatus, A. rufipalpis and A. ustulatus were sampled by pheromone traps in maize fields. During the study more than 80000 beetles were caught. The three most common species were A. ustulatus, A. sputator and A. rufipalpis. The distribution of the studied species was uneven. In south Hungary A. ustulatus, A, rufipalpis and A. sputator were the three most abundant species. In the Transdanubia A. sputator was the most abundant. A. ustulatus reached higher abundance in only three sites (3/12). A. obscurus occurred only in west Hungary (Transdanubia). In eastern Hungary the abundance of studied species was higher. In this reason we have to monitor the populations of these pests and if it is necessary we have to take actions against them. In Transdanubia the abundance were generally lower but in many cases reached the threshold of significant damage. Beyond that 13 additional species were sampled so the total number of sampled species was 19.

  • Comparison of different pheromone traps for monitoring of click beetle Agriotes ustulatus (Coleoptera Elateridae)

    The effectiveness of two trap types (YATLORf and VARb3 with CSALOMON® sex pheromone bait) for monitoring click beetle Agriotes ustu latus was compared near Karcag (East Hungary) in 2016. Additionally effectiveness of YATLORf traps placed on ground and placed on a 25 cm high mound was also compared. Contrary to our expectations traps caught very few individuals thus our study could provide only preliminary results. Between traps and methods there were not significant differences but YATLORf traps placed on mounds caught more individuals than others. The swarming imagos of A. ustulatus were also detected two weeks earlier in 2016 than as usual. To prove the effect of the way of usage on the effectiveness of YATLORf traps new studies should be made.
