A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Biological Sciences University of Alaska Fairbanks August 2017 APPROVED: Pat Doak, Committee Chair Greg Breed, Committee Member Colleen Handel, Committee Member Christa Mulder, Committee Member Kris Hundertmark, Chair Department o f Biology and Wildlife Paul Layer, Dean College o f Natural Science and Mathematics Michael Castellini, Dean of the Graduate School ABSTRACT Across the Arctic, taller woody shrubs, particularly willow (Salix spp.), birch (Betula spp.), and alder (Alnus spp.), have been expanding rapidly onto tundra. Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity.

Their potential was tested against the three economic insect pests, the great spruce bark beetle, Dendroctonus micans Kugelann (Coleoptera: Curculionidae); the pine processionary, Thaumetopoea pityocampa (Lepidoptera: Thaumetopoeidae); and the gypsy moth, Lymantria dispar (Linn.) (Lepidoptera: Erebidae), to find an effective biological control agent. All isolated bacteria were cultured and identified using VITEK bacterial identification systems and 16S rRNA gene sequence analysis. ThebacteriawereidentifiedasEnterobacter cloacae complex (isolate 1M), Serratia marcescens (isolate 3M), Pseudomonas aeruginosa (isolate 4M), Kocuria kristinae (isolate 5M), and Serratia liquefaciens (isolate 8M). Laboratory experiments, carried out to evaluate the virulence of these isolates, showed that all isolated bacteria had a pathogenic effect on the tested pests. E. cloacae had 35, 56.7, and 84%; S. marcescens 50, 60.9, and 47.8%; P. aeruginosa 55, 69.6, and 48%; K. kristinae 40, 43.5, and 16%; and S. liquefaciens 45, 65.2, and 36% mortality rates on the larvae of D. micans, T. pityocampa,andL. dispar, respectively. The isolated bacteria can be considered in integrated pest control programs.

  • Management of Sweet Potato Weevil, Cylas Formicarius: a World Review
    ® Fruit, Vegetable and Cereal Science and Biotechnology ©2012 Global Science Books Management of Sweet Potato Weevil, Cylas formicarius: A World Review Rajasekhara Rao Korada1* • Samir Kanti Naskar2 • Archana Mukherjee1 • Cheruvandasseri Arumughan Jayaprakas2 1 Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar - 751 019, India 2 Central Tuber Crops Research Institute, Sreekariyam, Thiruvananthapuram - 695 017, India Corresponding author : * [email protected] ABSTRACT Sweet potato is infested by many insect pests. Sweet potato weevil (SPW) Cylas formicarius (Fab.) is the important insect pest throughout the world, wherever it is grown. The weevil is managed by a package of practices together called integrated pest management (IPM). In India, a few genotypes of sweet potato have shown durable resistance throughout 2006 to 2011. A new screening method of germplasm, volatile-assisted selection (VAS), was developed to identify resistance/susceptibility in sweet potato genotypes based on the volatile chemicals that are released. Transgenic sweet potato was not successful at the field level. Farmers in Asia practice intercropping of sweet potato with ginger, bhendi, taro and yams to reduce the incidence of pests as well as to conserve soil moisture. Entomopathogenic fungi and nematodes are used successfully to control C. formicarius in the West and Latin America. Female sex pheromone (Z)-3-dodecen-1-ol (E)-2-butenoate has changed the pest dynamics in the field and has become an important tool in C. formicarius IPM. It was used to monitor and trap male weevils, thus reducing the reproductive success of female weevils. A number of botanical pesticides are available and their use is limited in developed countries.

The actual arthropod taxa comprising the chick diet are however rarely known, complicating assessments of ecological interactions. In this study, I identified the nestling diet of Svalbard snow bunting (Plectrophenax nivalis) for the first time. Faecal samples of snow bunting chicks were collected in Adventdalen, Svalbard in the breeding season 2018 and analysed via DNA metabarcoding. Simultaneously, the availability of prey arthropods was measured via pitfall trapping. The occurrence of 32 identified prey taxa in the nestling diet changed according to varying abundances and emergence patterns within the tun- dra arthropod community: Snow buntings provisioned their offspring mainly with the most abundant prey items which were in the early season different Chironomidae (Diptera) taxa and Scathophaga furcata (Diptera: Scathophagidae), followed by Spilogona dorsata (Diptera: Mus- cidae).

  • Mating Cluster Behaviour in the Solitary Bee Colletes Succinctus
    To confirm species identification a small sample was Mating cluster behaviour in the collected in 2006 when the population reappeared. The identity was established from a male specimen whose solitary bee Colletes succinctus morphological characters, including features in the (Linn.), Hymenoptera, Colletidae genitalia, match those of Colletes succinctus , the girdled Colletes (Saunders, 1896; Step, 1946).

These bees were occupying plots of soil in the garden of Bogendreip Farm (Fig 1). Only in the last few years had Mr. Watt Fig. 2.
