Abstract
Topical application of crude ethanol extracts (CEs) of the leaves of 43 of 51 Jamaican plants produced varying degrees of multiple acaricidal effects on engorged Boophilus microplus Canst., including mortality (M) inhibition of oviposition (IO) and inhibition of embryogenesis (IE). Acaricidal indices (AI) ranged from 50 to 100 for the CEs of 29 plants, 38 to 47 for 9 plants and from 0 to<25 for 13 plants. The most active CEs (AI values in parentheses) were those of: Simarouba glauca (100) > Symphytum officinale (99) > Nicotiana tabacum (95) > Hibiscus rosa-sinensis (93) > Ervatamia divaricata= Ricinus communis (82) > Salvia serotina (80) > Stachytarpheta jamaicensis (79) > Blighia sapida= Ocimum micranthum (76) > Spigelia anthelmia (75) > Cycloptis semicordata (74) > Mormodica charantia (71) > Bontia daphnoides (69) > Azadirachta indica (68) > Capsicum annum= Cayhranthus roseus = Petiveria alliacea (66) > Gliricida sepium (64) > Lippia alba (62) > Cuscuta americana = Erythrina corallodendrum (61) > Piper amalago (60) > Cannabis sativa= Cecropia peltata (58) > Dioscorea polygonoides (56) > Artocarpus altilis (53) > Crotalaria retusa (51) > Citrus aurantium (50).....
