Temperature Effects on Host-Seeking by Larval American Dog Ticks, Dermacentor variabilis (Say)

Author Institution: Associate Professor, Department of Entomology, The Ohio State UniversityHost-seeking activity of larval American dog ticks was measured by determining the proportion of unengorged larvae attached to white-footed mice, Peromyscus leucopus (Rafinesque), trapped overnight in Columbus, Ohio, in 1983. A positive linear correlation was found between larval host-seeking activity and evening ambient temperature. No similar correlation was found between this activity and insolation, relative humidity, average daily temperature, or ambient temperatures taken at other times of the day or night

Studies of the Mexican Deltocephalinae : New Species of Eutettix and Two Allied New Genera (Homoptera: Cicadellidae)

Author Institution: Department of Zoology, The Ohio State University, Columbus, Ohio 43210Two new genera, Alladanus and Cozadanus, and sixteen new species of Deltocephalinae (leafhoppers) are described from Mexico. Twelve species, all new, are described and placed in the genus Eutettix Van Duzee: E. contorqus, E. lanceolatus, E. dentatus, E. alvadus, E. chelatus, E. spinus, E. pedus, E. divergens, E. krameri, E. guevarai, E. transversus, and E. ortegai. Two new species, A, cephalatus and A. mexellus, are described and placed in the new genus Alladanus, of which A. cephalatus is the genotype. Two new species, C. globosus and C. serratus, are described and placed in the new genus Cozadanus, of which C. globosus is the genotype
