Kozlov, Elena L. Zvereva, Andrey V. Selikhovkin] We separated direct and indirect effects of sulphur dioxide on performance of the leaf beetle Melasoma lapponica L. Ramets of naturally growing bushes of Salix borealis (Fries) Nasar., enclosed in plastic chambers, were infested by 1st instars and fumigated with either ambient air or 1 of 4 SO2 concentrations (100, 200, 500, and 1,000 μg/m3) for 15 d. Simultaneously, larvae that were fed leaves from these chambers were reared outside chambers. Survival of insects grown outside chambers increased or stayed the same with an increase of SO2 concentration applied to their host individuals, indicating that action of SO2 from food was neutral or beneficial for insects. Therefore the decrease in survival of insects grown in chambers with an increase of SO2 concentration was attributed to the direct toxicity of sulphur dioxide. Changes in beetle weight were not significant in both experiments. © 1996 Entomological Society of America Physiological and Chemical Ecology nationallicence Melasoma lapponica nationallicence performance nationallicence sulphur dioxide nationallicence Kozlov Mikhail V.
