Diversity and Abundance of Nonculicid Biting Flies (Diptera) In A Zoo Environment.

The diversity of nonculicid biting flies was surveyed in Sunset Zoo, Manhattan, KS, by carbon dioxide-baited traps. A total of 8,399 nonculicid biting-fly females representing 32 species and 5 families were collected. Twenty-one biting midge (Ceratopogonidae: ) and 7 black fly (Simuliidae) species were collected, including new state records of 3 and 1 simuliid.

EHDV-2 Infection Prevalence Varies in after Feeding on Infected White-Tailed Deer over the Course of Viremia.

Epizootic hemorrhagic disease viruses (EHDVs) are arboviral pathogens of white-tailed deer and other wild and domestic ruminants in North America. Transmitted by various species of , EHDVs circulate wherever competent vectors and susceptible ruminant host populations co-exist. The impact of variation in the level and duration of EHDV viremia in white-tailed deer () on infection prevalence is not well characterized.

Crowdsourcing methodology: establishing the Cervid Disease Network and the North American Mosquito Project.

Crowdsourcing is obtaining needed services, ideas, or content by soliciting contributions from a large group of people. This new method of acquiring data works well for single reports, but fails when long-term data collection is needed, mainly due to reporting fatigue or failure of repeated sampling by individuals. To establish a crowdsourced collections network researchers must recruit, reward, and retain contributors to the project.

Susceptibility of a North American Culex quinquefasciatus to Japanese Encephalitis Virus.

Japanese encephalitis virus (JEV) is a flavivirus that is transmitted by Culex (Cx.) tritaeniorhynchus in tropical and subtropical regions of Asia. The endemic transmission cycle involves domestic pigs and avian species that serve as amplification hosts; humans are incidental hosts that cannot develop a high-titer viremia sufficient for mosquito infection.

Evaluation of mass trapping and mating disruption for managing Prionus californicus (Coleoptera: Cerambycidae) in hop production yards.

Larvae of Prionus californicus Motschulsky (Coleoptera: Cerambycidae) feed on the roots of many types of woody perennial crops and are serious pests of hop in the northwestern United States. The adult males are strongly attracted to a volatile sex pheromone, (3R,5S)-3,5-dimethyldodecanoic acid, that is produced by females. Here, we summarize the results of field experiments that evaluated the potential for using the synthetic pheromone (in a blend of all four possible stereoisomers) to manage infestations of P.

Synthesis and field tests of possible minor components of the sex pheromone of Prionus californicus.

Earlier work has shown that adult male Prionus californicus Motschulsky (Coleoptera: Cerambycidae) are attracted to the female-produced compound (3R,5S)-3,5-dimethyldodecanoic acid, and to a synthetic mixture of the four stereoisomers of 3,5-dimethyldodecanoic acid. Here, we report the results of field trials that tested whether or not three structurally related compounds (methyl 3,5-dimethyldodecanoate, 3,5-dimethyltridecanoic acid, and 3,5-dimethylpentadecanoic acid), present in extracts of virgin females, are attractive, and whether or not they influence attraction to 3,5-dimethyldodecanoic acid. In a trial with single components, only traps baited with the acid or its methyl ester captured more beetles than did control traps; catches to the acid were five times higher than to the methyl ester.
