  • Honey Bees Tune Colony and Individual Foraging to Multi-Predator Presence and Food Quality
    Fearful Foragers: Honey Bees Tune Colony and Individual Foraging to Multi-Predator Presence and Food Quality Ken Tan1,2*, Zongwen Hu2, Weiwen Chen2, Zhengwei Wang2, Yuchong Wang2, James C. Nieh3 1 Key Laboratory of Tropical Forest Ecology, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Science, Kunming, China, 2 Eastern Bee Research Institute, Yunnan Agricultural University, Kunming, China, 3 Division of Biological Sciences, Section of Ecology, Behavior, and Evolution, University of California San Diego, La Jolla, California, United States of America Abstract Fear can have strong ecosystem effects by giving predators a role disproportionate to their actual kill rates. In bees, fear is shown through foragers avoiding dangerous food sites, thereby reducing the fitness of pollinated plants. However, it remains unclear how fear affects pollinators in a complex natural scenario involving multiple predator species and different patch qualities. We studied hornets, Vespa velutina (smaller) and V. tropica (bigger) preying upon the Asian honey bee, Apis cerana in China. Hornets hunted bees on flowers and were attacked by bee colonies. Bees treated the bigger hornet species (which is 4 fold more massive) as more dangerous. It received 4.5 fold more attackers than the smaller hornet species. We tested bee responses to a three-feeder array with different hornet species and varying resource qualities. When all feeders offered 30% sucrose solution (w/w), colony foraging allocation, individual visits, and individual patch residence times were reduced according to the degree of danger. Predator presence reduced foraging visits by 55–79% and residence times by 17–33%. When feeders offered different reward levels (15%, 30%, or 45% sucrose), colony and individual foraging favored higher sugar concentrations.

  • Apis Mellifera)
    Experimental and Applied Acarology https://doi.org/10.1007/s10493-020-00525-y Electrotarsogram responses to synthetic odorants by Varroa destructor, a primary parasite of western honey bees (Apis mellifera) Michael Light1 · Dave Shutler1 · G. Christopher Cutler2 · N. Kirk Hillier1 Received: 21 September 2019 / Accepted: 8 July 2020 © Springer Nature Switzerland AG 2020 Abstract Olfaction is a key sensory modality for many arthropods and could be used as a tool in pest management through manipulation of pest behavior. Management of Varroa destructor, important parasitic mites of honey bees, could be improved through better understanding of the chemical ecology of this host-parasite relationship. We refned techniques of mount- ing mites to obtain electrophysiological recordings (electrotarsograms) of their responses to synthetic odor stimuli. Results of 271 electrotarsogram recordings from V. destructor revealed responses to 10 odorants relative to solvent controls. Electrotarsogram responses to methyl palmitate, ethyl palmitate, and 2-heptanol were highest at the lowest stimulus loading (10 ng) we tested, suggesting that V. destructor may have acute sensitivity to low concentrations of some odors. Results suggest that odorant origin (e.g., methyl oleate from honey bee larvae, geraniol from adult honey bee alarm pheromone, and α-terpineol, a plant secondary metabolite) can infuence the degree of electrophysiological response. Varroa destructor tended to be more responsive to known attractants and repellents relative to previously unexplored odorants and some repellent terpenes. Electrotarsograms ofer the potential for screening odors to determine their importance in V. destructor host detection.

  • The Effects of Native and Non-Native Grasses on Spiders, Their Prey, and Their Interactions
    Spiders in California’s grassland mosaic: The effects of native and non-native grasses on spiders, their prey, and their interactions by Kirsten Elise Hill A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, and Management in the GRADUATE DIVISION of the University of California, Berkeley Committee in charge: Professor Joe R. McBride, Chair Professor Rosemary G. Gillespie Professor Mary E. Power Spring 2014 © 2014 Abstract Spiders in California’s grassland mosaic: The effects of native and non-native grasses on spiders, their prey, and their interactions by Kirsten Elise Hill Doctor of Philosophy in Environmental Science and Policy Management University of California, Berkeley Professor Joe R. McBride, Chair Found in nearly all terrestrial ecosystems, small in size and able to occupy a variety of hunting niches, spiders’ consumptive effects on other arthropods can have important impacts for ecosystems. This dissertation describes research into spider populations and their interactions with potential arthropod prey in California’s native and non-native grasslands. In meadows found in northern California, native and non-native grassland patches support different functional groups of arthropod predators, sap-feeders, pollinators, and scavengers and arthropod diversity is linked to native plant diversity. Wandering spiders’ ability to forage within the meadow’s interior is linked to the distance from the shaded woodland boundary. Native grasses offer a cooler conduit into the meadow interior than non-native annual grasses during midsummer heat. Juvenile spiders in particular, are more abundant in the more structurally complex native dominated areas of the grassland.

A. V. College, J. P. University, Chhapra, India 2School of Environmental Studies, Jawaharlal Nehru University, New Delhi, India (Accepted November 21, 2015) ABSTRACT Present study was conducted to reveals the community structure and diversity of spider species in different habitat types (gardens, crop fields and houses) of Saran; a part of Indo – Gangetic Plain, India. This area has very rich diversity of flora and fauna due to its climatic conditions, high soil fer- tility and plenty of water availability. The spiders were sampled using two semi-quantitative methods and pitfall traps. A total of 1400 individual adult spiders belonging to 50 species, 29 genera and 15 families were recorded during 1st December 2013 to 28th February 2014. Spider species of houses were distinctive from other habitats it showed low spider species richness. The dominant spider fami- lies were also differs with habitat types. Araneidae, Pholcidae and Salticidae were the dominant spi- der families in gardens, houses and crop fields respectively. Comparison of beta diversity showed higher dissimilarity in spider communities of gardens and houses and higher similarity between spi- der communities of crop fields and gardens. We find that spiders are likely to be more abundant and species rich in gardens than in other habitat types. Habitat structural component had great impact on spider species richness and abundance in studied habitats.

  • Apheloria Polychroma, a New Species of Millipede from the Cumberland Mountains (Polydesmida: Xystodesmidae) PAUL E. MAREK1*
    Apheloria polychroma, a new species of millipede from the Cumberland Mountains (Polydesmida: Xystodesmidae) PAUL E. MAREK1*, JACKSON C. MEANS1, DEREK A. HENNEN1 1Virginia Polytechnic Institute and State University, Department of Entomology, Blacksburg, Virginia 24061, U.S.A. *Corresponding author, email: [email protected] Abstract Millipedes of the genus Apheloria occur in temperate broadleaf forests throughout eastern North America and west of the Mississippi River in the Ozark and Ouachita Mountains. Chemically defended with toxins made up of cyanide and benzaldehyde, the genus is part of a community of xystodesmid millipedes that compose several Müllerian mimicry rings in the Appalachian Mountains. We describe a model species of these mimicry rings, Apheloria polychroma n. sp., one of the most variable in coloration of all species of Diplopoda with more than six color morphs, each associated with a separate mimicry ring. Keywords: aposematic, Appalachian, Myriapoda, taxonomy, systematics Introduction Millipedes in the family Xystodesmidae are most diverse in the Appalachian Mountains where about half of the family’s species occur. In the New World, the family is distributed throughout eastern and western North America and south to El Salvador (Marek et al. 2014, Marek et al. 2017). Xystodesmidae occur in the Old World in the Mediterranean, the Russian Far East, Japan, western and eastern China, Taiwan and Vietnam. Taxa include species that are bioluminescent (genus Motyxia) and highly gregarious (genera Parafontaria and Pleuroloma); some form Müllerian mimicry rings. Despite their fascinating biology and critical ecological function as native decomposers in broadleaf deciduous forests in the U.S., their alpha-taxonomy is antiquated, and scores of new species remain undescribed.

Th is study compares diversity patterns of deadwood habitat structure and saproxylic beetle species in spruce forests with natural disturbance histories (wind and fi re) and human disturbance histories (clearcutting and clearcutting with thinning).
