Technical Bulletin For: Information Technology Solutions Red Clover Casebearer Coleophora Deauratella (Stoll) • Lepidoptera, Coleophoridae • COLDEA Technical Bulletin for: Information Technology Solutions Red Clover Casebearer Coleophora deauratella (Stoll) • Lepidoptera, Coleophoridae • COLDEA DISTRIBUTION Europe, Asia Minor, Tasmania, Lebanon and North America HOSTS Red Clover (Trifolium pratense) DESCRIPTION Wingspan: 9-13mm, body length 8mm. Head metallic bronze. Antennae dark grey, apex white, towards base thickened with dense dark coppery-bronzy scales [Antenna thickened with Adult Moth projecting scales at base to beyond the first three segments]. Forewings shining brassy bronze, towards apex coppery-tinged. Hindwings dark grey. Hatched larvae enter florets to feed, then move between florets by chewing holes through corolla, Larvae eventually causing feeding damage to pods and developing seeds Eggs White eggs are laid on the calyx of florets Adults take wing during June and July, attracted to the light. Larvae feed on developing seeds in LIFE HISTORY the fall, building themselves a case closely resembling the plant’s floret. They overwinter inside case amongst leaf litter, pupating in May. MONITORING INFORMATION LURE ACTIVE INGREDIENTS, SUBSTRATE & FIELD LIFE Z-7-12Ac and Z-5-12Ac in a Red Rubber Septum. Lure longevity: Thirty (30) days. TRAP TO USE Paper/Plastic Delta Trap or Uni Trap Hang traps near affected crops. Check with Cooperative Extension or Master Gardener for local MONITORING STRATEGY information and recommendations. CULTURAL & PHYSICAL Cutting/removing red clover silage in late May/early July appears to disrupt lifecycle and helps CONTROL prevent damage to seeds during bloom and seed fill period. .

Gillette Museum of Arthropod Diversity, Department of Bioagricultural Sciences and Pest Management Colorado State University, Fort Collins, CO 80523 Abstract A list of 1531 species ofLepidoptera is presented, collected over 15 years (1988 to 2002), in eleven southern West Virginia counties. A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains,

Abstract Additions, deletions and corrections are made to the Irish checklist of butterflies and moths (Lepidoptera). Elachista biatomella (Stainton, 1848) is added to the Irish list. The total number of confirmed Irish species of Lepidoptera now stands at 1480. Key words: Lepidoptera, additions, deletions, corrections, Irish list, Elachista biatomella Introduction Bond, Nash and O’Connor (2006) provided a checklist of the Irish Lepidoptera. Since its publication, many new discoveries have been made and are reported here. In addition, several deletions have been made. A concise and updated checklist is provided. The following abbreviations are used in the text: BM(NH) – The Natural History Museum, London; NMINH – National Museum of Ireland, Natural History, Dublin. The total number of confirmed Irish species now stands at 1480, an addition of 68 since Bond et al. (2006). Taxonomic arrangement As a result of recent systematic research, it has been necessary to replace the arrangement familiar to British and Irish Lepidopterists by the Fauna Europaea [FE] system used by Karsholt 60 Bulletin of the Irish Biogeographical Society No. 36 (2012) and Razowski, which is widely used in continental Europe.

Simple Summary: Insect pheromones are specific natural compounds that meet modern pest control requirements, i.e., species-specificity, lack of toxicity to mammals, environmentally benign, and a component for the Integrated Pest Management of agricultural pests. Therefore, the practical application of insect pheromones, particularly sex pheromones, have had a tremendous success in controlling low density pest populations, and long-term reduction in pest populations with minimal impact on their natural enemies. Mass trapping and mating disruption strategies using sex pheromones have significantly reduced the use of conventional insecticides, thereby providing sustainable and ecofriendly pest management in agricultural crops. In this review, we summarize the latest developments in sex pheromone research, mechanisms of sex pheromone perception, and Citation: Rizvi, S.A.H.; George, J.; its practical application in agricultural pest management. Reddy, G.V.P.; Zeng, X.; Guerrero, A. Latest Developments in Insect Sex Abstract: Since the first identification of the silkworm moth sex pheromone in 1959, significant Pheromone Research and Its Application in Agricultural Pest research has been reported on identifying and unravelling the sex pheromone mechanisms of Management.

C. deauratella (CBM) quantification, and (2) evaluating red clover heads for later spread to red clover seed production in the Peace larvae presence and/or damage. Moths were collected River region of Alberta in western Canada and since from each trap, identified, and counted.

CBM adults lay eggs on newly set red clover heads, Beginning in late June, destructive head samples were and developing larvae feed on developing seed within collected along a curved arc through the middle section individual florets.
