Aluminum (Al) is the most abundant metal in the Earth’s crust. It has a variety of applications in many
branches of industry, medicine, pharmacy and cosmetics. The mechanisms of toxicity of this metal
have not yet been elucidated. So far, the effects of pesticide containing Al have been investigated, while
the results describing the effect of different concentrations of this metal on phytophagous insects are
rare, especially in Serbia. In our experiment, larvae of gypsy moth (Lymantria dispar L., Erebidae) were
exposed to a chronic effect of dietary aluminum (treatment, T) (T1=50; T2 =250, T3=500 and T4=1000
microg/g of dry food), from hatching until the third day of the fifth larval stage (V3). Fitness traits
(relative growth rate – RGR, larval mass at V3, and development time – DT) were monitored, as the first
indicators of aluminum influence on growth and development.
Statistically significant differences were detected in all fitness traits between T2 and T4. In more detail,
differences were noticed between: Control – and treatments (T1 and T2) for larval mass and DT; Control
– and treatments (T3 and T4) for RGR and DT; as well as between T1 and T4 for RGR and larval mass. On
treatments T1, T2, T3, there are significant positive correlations between larval mass and RGR, while on
T2, T3 and T4, there are significant negative correlations between RGR and DT. Changes in insect fitness
traits can be the first warning signal of the aluminum presence in food.
