Fumigant toxicity of essential oil from Tanacetum balsamita L. (Compositae) against adults and eggs of Callosobruchus maculatus F. (Coleoptera: Bruchidae)
Archives of Phytopathology and Plant Protection 46 (17), 2080-2086
Abstract: The essential oil of Tanacetum balsamita L. was tested against Callosobruchus maculatus F. at the rates of 5.12, 7.23, 10.19, 14.36 and 20.24 μl/l air for adults and 5.3, 8.5, 10.8, 13.7 and 17.4 μl/l air for eggs. All experiments were conducted at 27 ± 1 °C and 65 ± 5% relative humidity. Mortality was counted after 24, 48 and 72 h of exposure and all adults (dead and alive) were taken out of the vials and the vials were left at the same conditions for further 35 days to assess progeny production. For mortality of eggs, unhatched eggs were counted after 7 days. The adults treated with oil were more susceptible than eggs. At highest dose (20.24 μl/l air) mortality of adults after 72 h, received 75.2%, but this amount for egg at 17.4 μl/l air after 72 h was 49.06%. The lowest LC₅₀ value on 72 h was observed in adults (1.96 μl/l air). Also, the lowest LC₉₅ value on 72 h was observed in adults (42.86 μl/l air). The percentage of reduced progeny on 72 h was 50.92% at 20.24 μl/l air. Our results suggest that T. balsamita can be used as an alternative to synthetic insecticides but higher dose may be needed.
