The wireworm Agriotes obscurus (L.) was con trolled at Lunenburg, Nova Scotia, with insecticides incorporated into the soil. Aldrin or heptachlor at 4 lb. per acre, and lindane at 1.25 lb., each significantly reduced the number of larvae per square foot and increased the yield of dry matter of forage for 3 years after application. A single application of aldrin or heptachlor at 3 lb. per acre resulted in increased yields of oats during the second season after application, and of leguminous forage plants during the third, but potatoes grown immediately after the application were not significantly less injured by wireworms than those grown on untreated check plots.

Elaterid female sex pheromone, while currently used for monitoring the adult life stage (click beetle), has only recently been explored as a potential management tool. Consequently, there is little understanding of how abiotic and biotic conditions influence the response of click beetles to the pheromone. We examined whether the response of male Agriotes obscurus L. (Coleoptera: Elateridae) beetles to a cellulose-based formulation of female sex pheromone (‘pheromone granules’) is influenced by air movement, presence of visible light, and month of beetle collection. In addition, we investigated the distance from which beetles were attracted to the pheromone granules. Click beetle response was determined by measuring movement parameters in free-walking arena experiments. The response to pheromone was not affected by the presence or absence of visible light. We found that beetles collected earlier in the season had increased activity and interaction with pheromone under moving air conditions, compared to beetles collected later. When controlling for storage time, we confirmed that individuals collected in May were less active than beetles collected in March and April. In the field, beetles were recaptured from up to 14 m away from a pheromone granule source, with over 50% being recovered within 4.4 h from a distance of 7 m or less. Understanding how abiotic and biotic factors affect pest response to pheromone can lead to more effective and novel uses of pheromone-based management strategies.

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 %).

Abstract Following the deregistration of lindane, several neonicotinoid insecticides have been registered as seed treatments for controlling wireworms in cereal crops. Unlike lindane, which did both, neonicotinoids provide crop protection but do not reduce wireworm populations. Hence populations of various economic species are growing in key wheat production areas of the United States and Canada, and there is a need for novel seed treatments that match the efficacy of lindane. Herein we evaluated broflanilide, a novel GABA-gated Cl- channel allosteric modulator that differs from the cyclodienes (e.g., lindane) in that it binds to a unique site in the GABA receptor. As such, broflanilide confers a new mode of insecticidal action (Group 30 MOA), and is the first meta-diamide insecticide developed. When evaluated in field trials over 7 yr at various rates, broflanilide at 5.0 g [AI]/100 kg wheat seed was as effective at protecting wheat stand from wireworm (Agriotes obscurus) injury as the current industry standard thiamethoxam at 20–30 g [AI]/100 kg seed. In addition, broflanilide at 5.0 g reduced neonate wireworms (produced from eggs laid in established wheat during the growing season) and resident wireworms (in the field at time of planting) by 73.1 and 81.1%, respectively, which is comparable to that reported for the previous industry standard lindane (75.3 and 57.6%, respectively). These studies show that broflanilide at 5.0 g [AI] will provide consistent wheat stand protection (equal to thiamethoxam at 20–30 g [AI]), and A. obscurus wireworm population reduction (equal to lindane at 59 g [AI]), and will do so at far lower dosages per hectare.
