Alate ants captured in a Johnson-Taylor suction trap at two locations in South-Central Texas from March 1979 to August 1980 were preserved, counted, and identified to species and sex. At the College Station site, 24 species/morphospecies were identif

The ratio of females to males in pseudergates, soldiers, nymphs, and alates of Reticulitermes flavipes (Kollar) was 1.03:1, 1.27:1, 1.14:1, and 1.12:1, respectively. Only in soldiers was the percentage of females significantly greater than that of ma

Sperm transfer through the epididymis, a prerequisite for insemination of cat fleas, Ctenocephalides felis (Bouché) was stimulated by exposure of unfed male fleas to juvenile hormone III residues for 3 d at 25 degrees C or exposure of unfed fleas to

Weight gain by adult cat fleas, Ctenocephalidesfelis (Bouché), was influenced primarily by the concentrations of protein and sodium chloride in the feeding solution. After 48 h of feeding, fleas fed whole blood weighed almost twice as much as fleas

Juvenile hormone III plays a major role in regulating feeding and reproduction in the adult cat flea, Ctenocephalides felis (Bouché). Both blood consumption and egg production increased in a dose-dependent manner up to a maximum at 1,250 ppm when fl

The activity of pyriproxyfen in the blood diet was investigated for its efficacy against adult, egg, and larval stages of the cat flea, Ctenocephalides felis (Bouché). Adult fleas were housed in plastic cages and fed treated bovine blood using an ar

When adult cat fleas, Ctenocephalides felis (Bouche), were fed concentrations of < or = 0.08 ppm lufenuron in cattle blood, egg hatch did not differ significantly from the controls. However, as the concentration of lufenuron in blood increased from 0

When cat fleas, Ctenocephalides felis (Bouche), were fed concentrations of lufenuron in cattle blood ranging from 0.5 to 4 ppm, adult mortality increased in a dose-dependent manner to a maximum of approximately 24% over a period of 10 d. Fleas treate

Adult cat fleas, Ctenocephalides felis (Bouché), were fed suboptimal in vitro concentrations of lufenuron in blood to allow hatching of flea larvae for cytological study. At concentrations of 0.125, 0.25, and 0.5 ppm, larval hatch was 64, 15, and 4%
