Effectiveness of carbaryl applications for the control of Ixodes dammini (Acari: Ixodidae) nymphs in an endemic residential area.
Ground applications of carbaryl in early June 1989 reduced populations of nymphal Ixodes dammini Spielman, Clifford, Piesman & Corwin by 100% in five 0.4-ha residential sites 72 h after application. High levels of control (greater than 90%) persisted for almost 2 mo. Five nymphs were recovered at the periphery of the sprayed plots at two sites 2 wk after spraying and nine nymphs were collected at the periphery of the sprayed plots at three of the sites 4-5 wk after application. At 8 wk after application, I. dammini nymphs were recovered within three of the sprayed plots. Chemical control of nymphal I. dammini may be a viable management practice for homeowners living in endemic areas to reduce the chances of acquiring Lyme disease.
