Мета. Встановити видовий склад шкідливої ентомофауни буряка столового в зоні Полісся України в залежності від сортових особливостей культури та виділити серед них домінуючі види. Методи. Польові, лабораторні, математично-статистичні, розрахункові. Результати. На основі багаторічного моніторингу в зоні Полісся України вперше встановлено видовий склад шкідливої ентомофауни буряка столового в залежності від стиглості сорту культури, виділено 9 домінуючих видів та визначена їх чисельність. Досліджено, що в посівах буряка столового найсприятливіші умови були для розвитку таких фітофагів, як бурякова листкова попелиця, частка якої у видовому складі становила 18,2 %, звичайна бурякова блішка – 7,8 %, бурякова мінуюча муха – 3,4 %, совки (озима – 5,8 %, люцернова – 10,8 %), ковалики (темний – 4,6 %, смугастий – 4,3 %), західний травневий хрущ – 4,6 %, мертвоїд темний – 0,3 % та ківсяки – 22,5 %. Висновки. Визначено, що в Поліссі України у таксономічній структурі шкідливого ентомокомплексу домінували фітофаги із рядів Coleoptera (ковалик темний – Agriotes obscurus L., ковалик смугастий – Agriotes lineatus L., західний травневий хрущ – Melolontha melolontha L., звичайна бурякова блішка – Chaetocnema concinna March) – 34,3 %, Homoptera (бурякова листкова попелиця – Aphis fabae Scop.) – 17,1 %, Lepidoptera (совка озима – Scotia segetum Schiff, совка люцернова – Heliothis viriplaca Hfn.) – 16,3 % та Diptera (бурякова мінуюча муха – Pegomyіa betae Curt.) – 6,3 %. Серед них є як багатоїдні, так і спеціалізовані види. Із класу Diplopoda значної шкоди завдавали ківсяки (ряд Julida – 22,5 %). Досліджено, що ранньостиглі сорти буряка столового більшою мірою заселяли ґрунтові шкідники (личинки коваликів за чисельності 4 екз./м2, західного травневого хруща – 1,9 екз./м2 , совки озимої – 2,4 екз./м2); пізнього терміну дозрівання – шкідники надземних органів (звичайна бурякова блішка – 3,3 екз./м2, бурякова мінуюча муха – 1,3 екз./рослину,гусениці совки люцернової – 3,7 екз./м2, бурякова листкова попелиця –20,5 %).

The results of the study of fauna of click beetles in the Republicof Mordovia are presented. By now, 58 species of click beetles have been recorded here. Adrastus pallens is a new record for therepublic. As per the literature information, 6 species of click beetles (Agriotes pilosellus, Melanotus crassicollis, Melanotus fusciceps,Liotrichus affinis, Pseudanostirus globicollis, Stenagostus rufus) are known and these indications require confirmation. Two species(Agriotes acuminatus, Limoniscus suturalis) are excluded from the fauna. Taking into account the literary information in the fauna ofMordovia, 64 species of Elateridae are known. Agrypnus murinus, Agriotes lineatus, Agriotes obscurus, Agriotes sputator, Dalopiusmarginatus, Ampedus balteatus, Ampedus pomorum, Hemicrepidius niger, Athous subfuscus, Prosternon tessellatum, Selatosomusaeneus are among the mass species. A list of the species is presented, which with a high degree of probability can still be found in therepublic

The research has been carried out in 2013–2014 in an organic farm located in Medsėdžiai village, Klaipėda district, and intensive farm located in Laiviai village, Kretinga district. Four agrocenoses have been investigated: wheat, triticale, oat, and multiannual grassland. Five pitfall traps were set out in each of agrocenosis and the traps were active from the last decade of April until the last decade of August. Ground beetle adults that were detected during the study belonged to 27 species and 15 genera. The most abundant ground beetle species were Poecilus cupreus L., Pterostichus melаnаrius Ill, Аmаrа аeneа Deg, Cаrаbus cаncellаtus Ill., Hаrpаlus rufipes Deg., Аnchomenus dorsаlis Pontop. and Bembidion properаns Steph., representatives of which were detected in large numbers in all without an exception investigated agrocenoses and in both types of farming. Two seasonal activity peaks of P. cupreus L. abundance were distinguished in the organic farm: first in the beginning of June and the second in the mid-July. Meanwhile, in the intensive farm it was observed in late May. Click beetle adults, identified in the study, were prescribed to 6 species and 4 genera. The most abundant click beetle species were Agriotes obscurus L., Agriotes lineatus L. and Agriotes sputator L. which occurred without an exception in all the agrocenoses and both types of farms. It was determined that the highest click beetle adults’ activity in the intensive farm was observed in the end of July while the maximum of click beetle adults’ activity in the organic farm was defined in June.

Abstract Several Agriotes click beetle species are important pests of vegetables and field crops. Monitoring for beetles is generally done with pheromone-baited traps maintained in permanent locations. Since dispersal is mostly by walking, such traps may deplete populations around them, leading to underestimations of populations relative to nontrapped areas, and of concomitant risk of wireworm damage to nearby crops. We placed sets of five pitfall traps in field headland areas in 2015–2017, of which two were baited with Agriotes obscurus (L) or Agriotes lineatus (L) (Coleoptera: Elateridae) pheromone. Of these, one was maintained in a permanent location, while the other moved among the remaining positions. Traps were checked weekly over the emergence period. For A. obscurus, fixed and moving traps initially collected similar numbers, but the latter collected significantly more later in the season, indicating depletion around fixed traps. Depletion was most pronounced after a period of cold weather, and around the peak swarming period. Depletion observed for A. lineatus was not statistically significant. This indicates pheromone-baited traps used for walking insects can underestimate populations, but depletion rates vary with species and temperature and should be accounted for when traps are used to develop action thresholds or time control strategies.
