“…C control; Ac 1 and Ac 2 acute exposure to 10 and 30 lg Cd/g dry food; Chr 1 and Chr 2 chronic exposure to 10 and 30 lg Cd/g dry food; Rec 1 and Rec 2 recovery from 10 and 30 lg Cd/g dry food cleavage of S-S bonds and the formation of bridges between the metal and sulfur in the peptide chains of proteins (Van Straalen and Donker 1994). It was established that in different organisms, the presence of heavy metals was found to reduce the activities of some enzymes: ATPase in rats (Carfagna et al 1996) and the shrimp Penaeus indicus (Satyavathi and Prabhakara Rao 2000), aminolevulinic acid dehydratase in wolf fish Hoplias malabaricus (Costa et al 2007), cholinesterase in Daphnia magna (Diamantino et al 2003) and alkaline phosphatase in Lymantria dispar (Vlahović et al 2009). It is interesting that these enzymes are not specific enzymes for metal detoxification, as well as midgut non-specific esterases.…”

“…Changes in variation of enzyme activities as well as changes in variation of phenotypic plasticity can also be used as indicators of exposure to contaminated environment (Callaghan et al 1998;Vlahović et al 2009). Many ecotoxicological studies discovered the existence of genetic variability for the adaptive responses of a population to acute changes in the environment.…”

Many biochemical, physiological and histological criteria have been used as indicators of exposures and effects of the contaminants. These changes can indicate the response of an organism to a specific environmental stressor. In the present paper, the effect of the acute and chronic exposure to cadmium as well as recovery from two cadmium concentrations (10 and 30 μgCd/g dry food) on gypsy moth (Lymantria dispar) midgut esterases was investigated. The influence of cadmium on trait plasticity was also examined. Esterases showed great sensitivity to low metal concentrations during acute and chronic treatments. Their activities during short-term exposure and after recovery significantly depended on cadmium concentrations. The esterases had greater index of plasticity during chronic treatments with 10 and 30 μgCd/dry food. Five esterase isoforms between 64 and 250 kDa were detected. Isoforms of esterases exposed to any of the two cadmium effects differed among several egg-masses. Isozymes were distinguished in one egg-mass during different cadmium treatments. We conclude that these enzymes could be considered potential and sensitive non-selective biomarkers for the presence of cadmium in food.

“…Under the influence of dietary cadmium, L. dispar 4 th instar was prolonged, with a reduction in larval mass (Ilijin et al 2010), changes known to be a consequence of high levels of juvenile hormones in the hemolymph. Vlahović et al (2009) found that cadmium induces inhibition of alkaline phosphatase an enzyme whose activity is partially under ecdysteroide control (Nemec & Ženka 1996). All previously published results from our group and the results of this experiment indicate that, cadmium induce similar effects as starvation in gypsy moth caterpillars.…”

The specific response of gypsy moth A1 neurosecretory neurons to different environmental stressors

et al. 2014

Changes in the number and morphometric parameters of A1 neurosecretory neurons (nsn) were analyzed in Lymantria dispar 4 th instar caterpillars, exposed for 3 days to different stressors: cadmium, high temperature and tannic acid. The relative cytoplasm density of A1 nsn was also estimated. Caterpillars reared on a diet supplemented with cadmium exhibited increased size of A1 nuclei (10 and 250 µg Cd per g of dry food weight), increased number of nucleolii in nuclei and raised relative cytoplasm density in all experimental groups. Cadmium obviously induces intensive synthetic activity in A1 nsn. The second stressor was high environmental temperature of 35• C. Decrease of all analyzed morphometric parameters suggests that acute exposure of 4 th instar caterpillars to 35• C, as well as 12 h recovery at optimal temperature of 23• C, reduced the activity of A1 nsn. Tannic acid was added to the artificial diet in the following concentrations: 1%, 2.5% and 5%. All estimated morphological parameters did not change after addition 1 and 2.5% of tannic acid. After addition of 5% of tannic acid, the activity of A1 nsn declined.

“…Despite significant differences between the results for both sexes, decrease in body weight under the impact of the studied metals was observed. Mircic et al (2010Mircic et al ( , 2013 and Vlahovic et al (2008Vlahovic et al ( , 2012 studied the impact of cadmium on the larvae of Lymantria dispar (Linnaeus, 1758), using a concentration of Cd at 50 mg kg -1 of fodder. When the larvae were given food containing this dose of Cd, the chronic effect on their body weight was found significant.…”

Martynov, V.O., Brygadyrenko, V.V., 2018. The impact of some inorganic substances on change in body mass of Tenebrio molitor (Coleoptera, Tenebrionidae) larvae in a laboratory experiment. Folia Oecologica, 45: 24-32.Addition of low concentrations of metal ions to the diet of saprophagous insects can impact on their metabolism over a short period of time, causing an increase or decrease in their body mass. This article presents a 14-day laboratory experiment evaluating the changes in the body mass of larval stage 3 of Tenebrio molitor (Linnaeus, 1758) induced by adding different inorganic substances (350 mg kg -1 of dry fodder) to the diet of the larvae. Following the addition of inorganic substances to the fodder, the most marked differences compared to the control were observed in the groups which consumed substrate with lead nitrate (the mass of the larvae increased on average by 102.6% compared to increase in mass in the control variant of the experiments), cobalt nitrate (by 96.9%), calcium chloride (by 89.1%) sodium triphosphate (by 86.0%), zinc chloride (by 83.5%). A nonsignificant effect (a tendency of increase in the body mass) on T. molitor larvae was caused by manganese sulfate (by 57.8%), aluminium nitrate (by 57.3%), iron oxide (by 51.5%), barium nitrate (by 47.9%), orthophosphoric acid (by 47.4%), manganese chloride (by 46.5%), calcium carbonate (by 27.7%), iron sulfate (by 24.2%) and ammonium heptamolybdate (by -7.5%). Therefore, 5 out of the 15 studied inorganic substances significantly stimulated the increase in the body weight of T. molitor larvae, and 7 manifested these capacities at the level of tendency (stimulated an increase in body weight averaging 43-58% over the 14-day experiment). The obtained data indicate a necessity for further study on the impact of inorganic pollutants on different stages of insects.
