    YELLOWJACKETS OF NAPA COUNTY NAPA COUNTY MOSQUITO ABATEMENT DISTRICT P.O. Box 10053 American Canyon, CA 94503 Phone (707) 553-9610 Fax (707) 553-9611 Website: napamosquito.org GENERAL INFORMATION Yellowjackets, commonly referred to as meat bees, are social wasps that live in colonies. They are often confused with bees. They are a more aggressive threat than bees. They do not have barbs on their stingers so they can sting more than once. They can also bite. In Napa County there are three aggressive pest species of yellowjackets. They are the Common yellowjacket (Vespula vulgaris), Western yellowjacket (Vespula pensylvanica), and the German yellowjacket (Vespula germanica). These species build their nests in underground holes, attics, and walls of homes. They can also build nests in rodent burrows, tree cavities or ground holes. When a nest is disturbed yellowjackets can inflict multiple stings that are painful and may be life threatening to individuals hypersensitive to the venom. Unlike honeybees, yellowjackets do not leave a stinger imbedded in the sting site therefore they can sting numerous times. Stinging and injured yellowjackets release a chemical alarm pheromone that attracts other worker yellowjackets. This can cause additional yellowjackets to attack. In the late summer months when yellowjacket populations increase they can create a nuisance in parks by scavenging for food from picnic and barbeque areas. They can cause structural damage to a home when they construct nests in walls or attics. Adults of some species are beneficial to man because they prey on flies and other insects. Yellowjackets use vegetable fibers from trees and shrubs, chewed and mixed with saliva, to produce a paper-like material for nest construction.

    Scientific Notes 193 APPLICATION OF ALARM PHEROMONE TO TARGETS BY SOUTHERN YELLOWJACKETS (HYMENOPTERA: VESPIDAE) HAL C. REED1 AND PETER J. LANDOLT USDA, ARS, 5230 Konnowac Pass Rd., Wapato, WA 98951, USA 1Current address: Department of Biology, Oral Roberts University, Tulsa, OK 74171 Alarm pheromones have been demonstrated for a number of species of social Vesp- idae including several hornets and yellowjackets (Vespines) (Landolt et al. 1997). Maschwitz (1964a, b) first demonstrated alarm pheromone responses in the yellow- jackets Vespula vulgaris L. and V. germanica (Fab.) in response to crushed wasps and body parts. Pheromone-mediated alarm has since been observed in other vespines: Dolichovespula saxonica (Fab.) (Maschwitz 1984), the southern yellowjacket V. squa- mosa (Drury) (Landolt & Heath 1987, Landolt et al. 1999), the eastern yellowjacket V. maculifrons (Buysson) (Landolt et al. 1995), Provespa anomala Saussure (Maschwitz & Hanel 1988), and Vespa crabro L. (Veith et al. 1984). 2-Methyl-3- butene-2-ol was identified as a component of the alarm pheromone of V. crabro (Veith et al. 1984), and N-3- methylbutylacetamide was isolated and identified as an alarm pheromone of the southern and eastern yellowjackets (Heath & Landolt 1988, Landolt et al. 1995). The source of alarm pheromones in social wasps generally is the venom, although the head is implicated as an additional source of alarm pheromone for V. vulgaris (Al- diss 1983) and V. squamosa (Landolt et al. 1999). Alarm behavior in V. germanica and V. vulgaris occurred in response to the squashed sting apparatus, sting sac, and sol- vent extract of the sting sac (Maschwitz 1964b) and in D.

Hunting and trapping seasons have been closed for many years and deer and furbearer populations were of primary concern. Our studies indicate that the deer population is high and opening the season is recommended. There appeared to be numerous mink and river otters, and again, opening the season is advised. Forty-eight species of birds were identified during the study. Fourteen species were identified as known or probable nesters. No evidence of wolves was found on the island, although there was a transplant in the 1960's. Terrestrial mammals observed included Sitka black-tailed deer, mink, river otter, Sitka deer mouse, Coronation Island vole, and vagrant shrew. Sea otters were commonly observed and harbor seals and Steller sea lions were numerous. Humpback whales were seen in Aats Bay and Egg Harbor as well as offshore.

When you book a hunt with us you will get an experienced, professional hunting guide not a "warm body with a guide's license". We help you prepare for your hunt before you arrive by helping get your gear organized, logistics arranged, and plans ironed out. All of this allows for better service and better success, as our past hunters will attest to. Don't hesitate to ask for our list of references. We are dedicated to making your adventure hunt as successful as possible. We operate in many different remote and scenic parts of Alaska allowing us to choose the area’s best suited to you and the game you wish to pursue. Whether it is brown or grizzly bear, Dall sheep, mountain goat, moose, caribou, Sitka deer, black bear, wolf or wolverine we can make it happen. We hold a sole use guide concession in the Denali Preserve adjacent to Denali Park. Being the only outfitter in this area gives us the opportunity to hunt hundreds of square miles without added pressure from other guides. We hunt Kodiak Island, the Alaska Range, and from our full service hunting/fishing lodge in the Lake Iliamna area. Before we get deep into the hunting I want to fill you in on the processes of getting a license for the big bears.

Stein and Dana L. Wrensch' ABSTRACT Since 1975 in Ohio, there has been an escalation in the number of complaints and inquiries regarding yellowjackets (Vespula and Dolichovespula spp.) to the Ohio pest control operators, the Ohio Cooperative Extension Service (OCES) County Agents and the OCES Entomologists at the Ohio State University. A survey was distributed in May 1985 to both groups in order to determine the pest status of yellowjackets in Ohio. The results of this survey strongly suggest that yelIowjackets in Ohio are largely an "economic pest", with most economic disturbances associated with homeowners, outdoor businesses, and outdoor recreational facilities.

  • Siberian Goats and North American Deer: a Contextual Approach to the Translation of Russian Common Names for Alaskan Mammals CATHERINE HOLDER BLEE’
    ARCTIC VOL. 42, NO. 3 (SEPTEMBER 1989) F! 227-231 Siberian Goats and North American Deer: A Contextual Approach to the Translation of Russian Common Names for Alaskan Mammals CATHERINE HOLDER BLEE’ (Received 1 September 1988; accepted in revised form 19 January 1989) ABSTRACT. The word iaman was used by 19th-century Russian speakers in Sitka, Alaska, to refer to locally procured artiodactyls. The term originally meant “domesticated goat” in eastern Siberia and has usually been translated as“wild sheep” or “wild goat” in the American context. Physical evidence in the formof deer bones recovered during archeological excavations dating to the Russian period in Sitka suggested a reexamination of the context in which the word iaman was used bythe Russians. Russian, English, Latin and German historical and scientific literature describing the animalwere examined for the context in which the word was used. These contexts and 19th-century Russian dictionary definitions equating wild goats with small deer substantiate the hypothesis that the word iuman referred to the Sitka black-tailed deer by Russian speakers living in Sitka. Key words: Alaskan mammals, Alaskan archeology, historical archeology, ethnohistory, Russian translation, southeast Alaska, faunal analysis, Russian America RI~SUMÉ.Le mot iaman était utilisé au XIXe siècle, par les locuteurs russes de Sitka en Alaska, pour se référer aux artiodactyles qui cons- tituaient une source d’approvisionnement locale. Ce terme signifiait à l’origine (( chèvre domestique )> dans la Sibérie de l’est et a généralement été traduit comme (( mouton sauvage >) ou (( chèvre sauvage )) dans le contexte américain. Des preuves physiques sous la forme d’os de cerfs trouvés au cours de fouilles archéologiques datant de la période russe à Sitka, indiquaient que le contexte dans lequel le mot iaman était utilisé par les Russes devaitêtre réexaminé.
